There are a variety of scenarios in which heating, ventilation and air conditioning (HVAC) professionals find themselves when working on heating and cooling systems. While there are a variety of tools needed for these jobs and the possibilities are almost endless, there are several different scenarios that lend themselves to a fundamental group of HVAC tools.

In-floor radiant heating HVAC tools
Radiant heating is becoming more popular as it’s a proven way to save energy in the home, so more heating and cooling professionals are being asked to install this type of heating system. Drawing from the tools already at their disposal, those who work in the heating industry are often able to tackle these jobs without any additional supplies besides those that come as part of the floor heating system. There are specific radiant heat tools, and those include a foamboard stapler, foamboard staples, pex-to-wire tool (for securing pex-to-wire with a steel clip), and, of course, the pex-heating tubing itself and the fittings that go with it.

Fiberglass ductwork HVAC tools
Working with fiberglass is probably one of the most common materials that HVAC professionals come in contact with. It is involved with many heating and cooling systems, and thus, the tools needed to work with or repair it are an important part of any heating and cooling worker’s arsenal. There are a number of types of equipment specific to working with fiberglass, such as knives, ties and tools. One such HVAC tool, the flex duct tool, provides three-in-one capabilities, allowing workers to cut through duct and wire, as well as providing a tie tensioning mechanism.
Several other tools in this vein are a good investment for ductwork.

Metal ductwork HVAC tools
This genre of heating and cooling work perhaps comes with the requirement for the most equipment! HVAC workers typically use hammers, saws, riveters, drills, caulking, power tools, and other equipment to make the job easier. There are a number of folding tools to consider for this type of work, which free up space in your bag. A few include the hand seamer, which provides powerful leverage but is still compact; the mini brake, which makes a bend in galvanized steel up to 135 degrees; and alignment tools that fold down to relatively small sizes.

Multi-purpose HVAC tools & equipment
There are of course a number of other types of HVAC equipment that are necessary on the job. They include things that make work a bit easier and more comfortable: items like aprons, knee pads, face masks, power tools and the like. It’s also a good idea to have a reliable bag large enough to carry the necessary equipment but not too heavy or cumbersome. The larger specialty HVAC tools don’t have to be carried around at all times. With these HVAC tools, working in the heating and cooling field will be that much easier, and workers will have what they need to get a variety of jobs done properly.



Air filters are a big part of HVAC systems and their main job is to trap any debris or particles that can otherwise congest the HVAC unit. The indoor air consists of dust particles, microorganisms, animal fur and other smaller debris that can easily pollute the air. If that happens the HVAC needs to have a way of screening the incoming air so that the particulates can be left on the filter. In some units, you will find that even the outgoing air finds a sieve right before it exits the system not to run the risk of some particles being blown back to the system. In simpler words, the filter’s main role is to allow only the air to enter the heating and cooling unit and block the entry of debris. A system that can cause balanced air spots in the entire house must be very expensive and we need to take care of it. When you replace a blocked and damaged af, you can help prolong the life of your costly HVAC system. You are advised to assess the unit often to find out if there is a need to change the filter.

Some filters are not long-lasting, and they easily get damaged. If you prefer using these cheap items you should also be ready to replace them often to avoid affecting the efficiency of your systems. If you need an economical product, you may go for the spun fiberglass material. Even if they are inexpensive, you need to note that they are only good at trapping big particles. As a result, you need to change them at least once a month. These can be expensive in the long run because they are limiting you to not more than one month replacement period.

The other common types are called pleated HVAC filters which are more reliable than the fiberglass options. They can catch slightly smaller air particles than the types described above because of their pleats. Even so, they need to be changed occasionally.

Another very effective and reliable item is called electrostatic. It is specifically designed to catch the tinier debris that would otherwise pass through if one uses the aforementioned sieve options. If it can capture tiny debris then catching larger ones is not a problem. As their name suggests, these items use static charges which are generated as air is passed through them. The charge lures and captures the particulates regardless of their size. These items are versatile as they are reusable but they are expensive, unfortunately. Since they can be reused, electrostatic filter styles are more costly than disposable styles. If you clean them regularly you can use them for a much longer time.

Another highly dependable option is called the high-efficiency particulate arrestance or HEPA. It is one of the most highly efficient HVAC filters you can find and its success rate is ninety-nine-point-seven percent. Apart from the air particles, these sieves are known to prevent even allergens from entering the heating and cooling system.


HVAC control systems allow building operators to properly control the temperature, humidity, and ventilation throughout a building. The first HVAC control systems were pneumatically operated. However, technological innovations have standardized electronic and direct digital controllers. Some control systems are more sophisticated than others. Some are programmable, while others can even be operated via the Internet.

Pneumatic controls
Pneumatic controls use compressed air as a power source. These analog controllers were once the most commonly used in non-residential buildings. Pneumatic control systems make it simple to regulate temperature, humidity, and pressure. There are still a large number of pneumatic control systems in place in older buildings. However, pneumatic control systems are quickly being replaced by more sophisticated analog, electronic and digital controls.

Analog electronic controls
Due to increased flexibility, analog electronic controls began to replace pneumatic controllers. Analog electronic controls utilize analog semiconductor components as a power source. Many times a single device was able to manipulate several electronic controllers. This control device is designed to operate all functions of a specific application such as control of a single zone air handler. Due to their high cost analog electronic controls are being replaced by direct digital controls.

Direct digital controller
Unlike analog electronic controllers, direct digital controls usually have analog and digital inputs and outputs. The inputs are used to measure temperature, humidity, and pressure. Digital inputs normally use contacts from a control device. Analog inputs, on the other hand, measure a voltage or current from a sensing device that measures temperature, humidity, velocity, and pressure. Many direct digital controllers are programmable, meaning their program codes may be manipulated for individual preferences.

Control valves and dampers
One of the most common methods HVAC systems use for controlling the flow of air is control valves. In an HVAC system, a valve is a pipe fitting used to control the flow of air through opening, closing, or partially obstructing entryways into specified areas in a building. Control valves are usually either two-way or three-way mixing valves. A damper is a specific type of valve that regulates airflow from inside an air duct. Dampers commonly come in the form of plates which may open and close manually or electronically.

HVAC control systems use actuators to move or control the system’s valves. Actuators usually operate by either electricity or pneumatic pressure. The electric actuators can be either direct or remote mount. Actuators can also be spring return or non-spring return. Some HVAC control systems use low-voltage actuators, which are available through select manufacturers. HVAC systems designers may choose between factory-mounted actuators or linkages for field installation.

Building automation systems
Some HVAC control systems can link to a building automation system, a computerized network of electronic devices that allow monitoring and controlling of the climate of a building. This includes lighting, temperature, humidity, and other variables. Building automation systems allow operators more control over HVAC system functions by allowing local or remote control, as well as occupancy scheduling or configuration.

Knowledge of HVAC control systems and products will allow you to make informed decisions when installing and designing your HVAC project. Some simpler projects will only require minimal controls and will not need some of the more sophisticated features. Other larger projects may require advanced integration into building automated systems.


HVAC professionals and engineers may choose to use HVAC design software to assist in creating plans for installing an HVAC system in a building. The software assists in various aspects of the HVAC design process, such as calculating room-by-room loads and airflow, duct system layouts, and determining necessary materials for the specified project. However, each software is different. Some are more specialized in certain functions than others.

HVAC system analysis software
Many software companies offer HVAC system analysis tools, which are designed to quickly evaluate the energy and economic performance of a prospective design. This type of tool is appropriate for an initial sketch of a proposed design. This will give HVAC professionals and engineers a general idea of how various system and equipment combinations would work to help make the most efficient choices. The analysis software usually produces reports and graphs comparing each proposed design’s benefits.

Comprehensive HVAC modeling software
Creating a proper HVAC system design can be complicated, due to all the various factors involved. However, a comprehensive HVAC modeling software will include a variety of designs, analyses, and calculations you need to create the right HVAC system design. HVAC modeling software can save time and energy compared to creating blueprints by hand. Modeling software assists in designing pipe and duct configurations. Usually, the software allows the user to apply the proposed design to chosen specifications.

Materials selection software
Building and installing an HVAC system usually requires a large amount of materials and parts. It can be confusing trying to decide which parts are compatible with other parts and which ones are the most economical. A materials selection software program will calculate the performance of components in a proposed HVAC design. This will allow the user to test the performance of various combinations of parts and materials for different design possibilities. This gives the user the necessary data to make the best decisions when purchasing materials.

Electronic charts and calculators
Other useful software tools commonly available on the HVAC market are calculators and electronic charts. Calculators assist in determining leed compliance on proposed HVAC system designs. Electronic charts are useful for measuring and comparing different variables, such as the range of temperatures, which would be comfortable for cooling applications. Some charts calculate the condenser relief before inputting the data into system analysis. Charts for constant condenser temperature unloading curves are also available.

Software support resources
It is recommended to consider available software support resources provided by the software company when considering what HVAC design application to purchase. A software company needs to offer an effective and efficient customer support service to help with any usability issues or questions. The company should have a customer service hotline available to all who have purchased their programs. Additionally, an online knowledge base may help to provide some solutions.

An overview of HVAC design software and all the various options is important when choosing the right program for a company or HVAC project. Each company and project works differently, but there will usually be a software program that will work for each individual circumstance. The key is to gather as much information as possible on the various software options before making a decision.


A reliable heating, ventilation and air-conditioning (HVAC) unit must have professionally installed ductwork. The main role of ducts in this HVAC system is to bring incoming air and remove outgoing air. They are airflows or air paths for supplying, returning and exhausting air from the system. Hence, their main role is to enable safe indoor air quality and comfortable temperature levels.

The system’s success mostly depends on the duct design. There are many types of ducts and some of them include the following:

Pre-insulated air ducts – the older duct system is made of sheet metal, which is first fixed according to the selected design and then cushioned to create insulation. Today this is undesirable. There is a version of pre-insulated aluminum ducting that features very solid insulation panels that do not require added lagging. They are fixed once and for all. Even so, the pre-insulated styles that are mainly in use now are two: polyurethane foam panels and phenolic foam panels. The former comes in various forms. However, today, the type which substitutes various gasses for water is very much in use. It uses pentane as the foaming instrument instead of hc, cfc and other related gasses. These panels are also covered with aluminum sheets on each side using varying thicknesses. Sometimes, the manufacturers coat the inside using aluminum sheets and two hundred micrometers of pre-painted sheet metal on the outside.

Phenolic foam panels are rigid to offer good insulation. They are almost the same as polyurethane foam panels. Flex- these are also called flexible ducts and boast many different shapes. Regarding HVAC use, however, flex ducts consist of plastic mounted over a wire coil. For insulation, the item may use glass wool, polyester fiber, and polyethylene. These are mostly used to fix the supply air outlets to the solid ductwork.

Fabric, alternatively called textile ducts or air socks. Fabric ductwork is made of a certain polyester textile. The aim is to allow an even air distribution down any length of a given system. They can be made of porous or non-porous textiles and feature any color or design You could ask your HVAC designer to recommend the best item to use.

Fiberglass panels consist of pre-installed thermal insulation and are known to absorb sound more than any other type of ducting system. They need to be prepared by an HVAC installer because of cutting given angles accurately. The HVAC ducts consist of various elements besides themselves. These include take-offs that can be described as branch ducts used when ductwork possesses a main straight branch with many other sub-ducts branching from it. Other elements include vibration isolators inserted into the duct unit to reduce the noise and vibration caused by air handlers blowers.

Heads, boots and stacks are other common components to expect. The stacks are vertical ducts formed using oval or rectangular sections. The boot is used as a way of changing from a large duct to a narrow wall-mounted type. The head allows a transition to a wall-mounted air register or back to regular ductwork. Other parts include the volume control dampers, plenums, air terminals, and fire dampers.


By far, most of the resume advice given assumes that the job-seeker will be working in a corporate environment. For those working in the skilled trades, some of the corporate advice is not useful, and there are several things a skilled tradesman should include on his resume that are often overlooked by professional resume writers, who most frequently work with corporate job-hunters. When writing a resume for an HVAC professional, there are several things to remember:

Stick with the format to an extent for the most part, an HVAC professional should stick with the standard resume format. A good resume will have an objective statement. HVAC resumes should have a section for previous work experience, education and training. One thing to remember is that not all HVAC training occurs within the confines of a college or university setting. HVAC professionals should include the most significant training they have undergone and some of that training will very likely be training from professional seminars or workshops.

HVAC professionals will need to include a section for professional licensing and certifications. In addition to including information about state licensing, an HVAC professional will want to include any manufacturer certifications they may have obtained.

HVAC professionals can also benefit from including information about any unions, trade organizations, or professional bodies they belong to. Be specific, there can sometimes be a tendency to gloss over the job description segment on a resume when it feels like all the jobs have been virtually identical. A closer examination will reveal that this is not the case.

A good resume will include specific information about jobs and accomplishments. For example, installation and maintenance often require very different skill sets, and a job-seeker who has dealt primarily with installation should include descriptions of installation procedures that they have gained familiarity with.

Additionally, HVAC professionals should remember that the first person who reads their resume may not be another HVAC professional. Their resume may be reviewed by a secretary or human resources professional before being forwarded to the HVAC supervisor, so they should keep their resume free from jargon as much as possible.

Job-seekers will want to mention any equipment specialties they have learned through job experience or individual training, such as commercial refrigeration or residential maintenance. Tailor the resume to the job. As with standard resumes written for corporate job-seekers, HVAC resumes should be tailored to the specific job. For example, if the job description calls for experience with large-scale commercial HVAC equipment, the job-seeker will want to highlight the experience that they’ve had with large-scale equipment. When the job description specifies a list of equipment or processes the technician will be required to perform, it is worth it to include those same specifics in the job description or education section of the resume where applicable.

As many HVAC jobs require state licensing and/or EPA certification, it is wise to include a section in the cover letter or on the resume itself that specifies driving record, licensing information, and eEPAcertification number available upon request. It is not normally required that you include your driver’s license number, state licensing number, or EPA certification number in your resume, but inserting that sentence into your resume or cover letter shows that you have read the job advertisement and understand the requirements.

Consider a related job – in these tough economic times, finding a job can sometimes be challenging. HVAC professionals may wish to consider a job related to HVAC contracting. For example, they may wish to work in the sales department of an HVAC company; this job would most likely have more regular hours and a different pay scale than working as an HVAC technician, but the skills required might differ. For seeking a position in HVAC sales, the job-seeker will need to highlight his ability to work as part of a team and his ability to work directly with customers. He or she may also wish to accentuate any previous experience in HVAC installation.

Some HVAC professionals may wish to start a new career as an HVAC instructor. This can be an excellent related career for somebody who has had extensive experience in the HVAC industry. Applicants for these jobs will want to highlight their supervisory experience, particularly as that supervision was related to training less experienced employees. These positions will usually offer more regular hours and better pay than working as an HVAC technician.

The cover letter
While most job hunters focus on the resume, the cover letter is equally important. A good cover letter should be carefully tailored for each specific job opening and should explain any information on a resume that might be questionable. For example, if a job hunter has been out of work for eight months, the job hunter will need to include an explanation of this period of unemployment and a positive spin on it. For example, after XYZ company went out of business last February, I have been seeking a new position. I have worked temporarily as a laborer for ABC Staffing but am seeking a more permanent position. In this example, the job-seeker explains that while he has not been working regularly, he has not been idle.

Cover letters should also be tailored to the specific position. For example, if the job description states that the new technician will be working on state-of-the-art equipment, a job seeker may wish to include a statement that says, for the past four years, I have worked in HVAC maintenance. Much of that experience has been on older HVAC models. I look forward to the opportunity to work on state-of-the-art HVAC systems and to expand my knowledge about more modern HVAC equipment.

References and referrals
While networking is a common buzzword in corporate circles, it applies even more to skilled tradesmen. The best place to find a new job as an HVAC technician or professional is to consult with others in the HVAC industry. In some cases, the person responsible for hiring new technicians is not a professional hiring manager but a senior HVAC professional. Because of their experience in the industry, they will often be more favorable towards a candidate if that candidate comes referred by a colleague whose work they respect. Job-hunting can be stressful even in the best of circumstances, but a good HVAC resume will help a candidate stand out from the rest. While resume writing differs for HVAC professionals, it is no less complicated. Writing a resume for an HVAC professional is an essential part of any job search.


An HVAC (heating, ventilation and air-conditioning) system humidifier is an appliance that is used to raise the amount of moisture in the whole house, a single section of a house or a furnace/boiler. Its counterpart is called a dehumidifier which is used to minimize the moisture content inside a house. If you want to moisten your home some more, you may want to know which humidifier options can connect to your existing HVAC unit. They include the following:

Evaporative humidifiers, alternatively called wick or cool mist, evaporative humidifier consists of three main parts including the fan, wick and reservoir. Even so, there is a natural type that uses only two of these parts: the reservoir and the wick. There are also a few other traditional types that are no longer reliable because they become contaminated easily. Now, there are ultrasonic humidifiers that consist of one unit that has a humidifying chamber for outdoor air, an electric and external air supplier unit and a water storage tank. This tank has an inlet perforation in the bottom. The humidifying unit has a water-feeding perforation in the lower section of the compartment that divides the water tank and humidifying chamber. The older humidifier which consists of the wick, fan and reservoir would develop molds as minerals present in water accumulate on the wick over time. The work of the wick is to absorb and sieve water from a reservoir while offering a bigger surface area for evaporation. The work of the fan which is situated directly opposite is to propel a gush of air onto the wick to accelerate moisture evaporation. To avoid a gradual damage to the wick you should replace or rinse it often. If you do not, then it will become difficult for air to penetrate and your humidification efforts will hence be futile.

A steam humidifier or vaporizer is a special type that heats water to the boiling point and enables steam and water into the air. Some people add medicated inhalants to the steam to enhance their safety. The boiler requires more energy to heat the water.

Forced air humidifiers increase the moisture in the air for the entire house. They are used in buildings that have a forced air HVAC furnace in place. These are further grouped into bypass or drum, disc wheel and bypass flow-through styles. Each style is unique and has its pros and cons. The drum style consists of a pipe that conveys water into a reservoir connected to the furnace. The amount of water in the reservoir is leveled by a float valve. It also has a foam pad fixed on a drum and then linked to a tiny motor. This is inexpensive and requires only a change of pads. However, it can encourage the growth of molds if not maintained and assessed regularly. Disc wheel style looks like the drum bypass but it substitutes the foam pad for plastic discs that have tiny grooves on each side. The disc wheel neither demands replacement nor regular checkups. Even though expensive, it also has a larger surface area and is highly efficient. The bypass flow-through uses an electrically-controlled valve and a pipe for carrying water. The air is passed via an aluminum pad often called a biscuit with a matte ceramic coating to enhance its surface area.


What are zoning systems?
HVAC zoning systems have become a very popular option for new homes and homeowners use them to help conserve energy and reduce their monthly power bills. Zoning units are mechanisms that are controlled by thermostats. They are installed in various parts of a house to control the heating and cooling process according to the owner’s needs. For instance, if there are sections of your house that you do not use often, an HVAC zone unit can regulate air conditioning in those areas. It can let you heat or cool the areas only when you want to use them. For instance, the guestrooms lack regular demands for cooling and heating until guests come. If the room is not used for a whole month the owner can avoid using lots of energy to make the air in it comfortable. In simpler words, zones are just like the light switches you can turn on or off as you please.
It has programmable thermostats that you can manipulate as you wish. The item is very economical in that it can be used to minimize the number of times that an air conditioner or the boiler goes on and off within a day. Do you know why this is beneficial? It helps to elongate the lifespan of your equipment and also saves you money. If you want to install the zoning system in your house, the following tips might be useful to you.

How many zones are necessary?
This is a question that is asked by many building owners. The homes that currently are not applying the zoning technique have mainly one thermostat heating their main floor. The homes also use one air conditioning equipment and a furnace. So the thermostat facilitates the heating and cooling needs of the main floor and when it reaches satisfactory levels it shuts down the air conditioning equipment. The attic and basement heating and cooling needs, in this case, are disregarded even if necessary. The owners of such a house are likely to have a case of overheated or under heated spots in the entire house. To solve such a problem, one can introduce the zoning systems in the house. The attic, main floor and basement can get one or more thermostats. This will ensure that even the areas that are not used regularly have a thermostat for controlling warmth and coolness. The number of zones needed should mainly depend on the size of your home and your air conditioning preferences. On some occasions, the installation of many zones can cause some challenges. For instance, if the airflow via the evaporator coil is not enough, this could cause the system to ice over. The problem can be prevented by installing a two-stage outdoor condensing system instead of a one-stage air conditioning unit.

Important considerations
You should consider the budget before installing a new HVAC zone system. The more zones you want to fix the more money you have to spend. As a result, you have to plan the project carefully with the help of an HVAC professional. Remember that even an expensive project can be done carelessly thus costing you more money and time in the future.


Have you ever heard of the HVAC design calculations? They are usually done using some standard methods recommended by Acca (Air Conditioning Contractors of America). These include the manual j, manual d and manual s procedures. They are the approved protocols for creating safe and reliable heating ventilation and air-conditioning systems. In the US, some codes demand these procedures to be confirmed before a building permit can be issued. The manual j is normally used to compute heat loss and gain in different rooms in a house, while the manual d calculations facilitate the determination of the right ductwork. Manual s is used to identify the right HVAC equipment for the chosen design. As a homeowner, why should you insist on the use of these calculations? As a homeowner, the project is yours and is meant to improve the air quality inside your house. You are also responsible for the cost of the project and that is why you deserve only the best. If the project is completed carelessly, you will be the person to suffer and regret. It is therefore important to insist that the task be done correctly even if your HVAC technician is a renowned expert.

There are advantages you can enjoy by doing things the right way and some of them include the following:

Many contractors also follow the right protocols. So if you decide to do things the right way you will have numerous interested contractors willing to use the above explained calculations to do your project. If you emphasize that you want real calculations done by the recommended procedures, you will eventually get what you pay for. Value for one’s money counts a lot regarding any home remodeling project. You can avoid repeat jobs in the future. A trial-and-error method of determining the correct HVAC design, equipment sizing, and ductwork is much more likely to produce some errors. If errors arise right in the initial step of identifying and analyzing the design, the implementation or installation procedure will most likely turn out bad.

Manual j, d and s calculations can enable the contractor to make the right recommendations and facilitate a homeowner’s decision-making process. This can prevent issues such as improper-sized equipment and poor installations. If you want to upgrade your HVAC system, these calculations can be used to determine the items that need to be changed and their proper sizes. By emphasizing these computations you can say something positive about yourself such as the seriousness involved in your project. This can help you attract serious contractors only. Since no paperwork is involved, your contractor can concentrate on implementing the HVAC design, which is finally suggested. Since your project would be done following all the right steps, you can expect to spend high amounts of money at the beginning. In the future, you will receive tax credits and rebates to help you recover your initial installation costs.

In today’s US economy, where low-paying jobs are becoming infrequent and menial, becoming an entrepreneur is the golden dream. By starting and operating an HVAC small business, the average working person could find themselves making over $100,000 a year; if they can successfully monopolize the market within their respective area. Yet, like any other business, an immense amount of dedication and determination is needed to reach the top of the financial ladder.

Capital investment
The initial capital for any small business should always be enough to cover company operating costs for the first three to six months. As the new business competition will be extremely fierce, profits may dip into the loss category until a respectable reputation is established within the service area. To fund such a venture without going into the negative, consumers should look towards angel investors and small business loans. Angel investors will fill the gap if an individual cannot obtain a small business loan from the government. In contrast, a small business loan is optimal for those who meet or exceed qualifications.

Obtain all certificates & licenses
It’s nearly impossible to get anywhere in an HVAC business without the proper certificates and schooling since the job requires extensive knowledge of technology and energy-efficient machines. Obtaining a certificate from an accredited college or trade school boosts the company’s reputation and lets consumers know they are in the hands of professionals. Someone with years of experience installing/repairing energy-efficient goods, such as air conditioners, will usually be able to gain a certification after just 40 hours of class time and work experience. Meanwhile, a novice to the field should spend at least 6-24+ months in training before they graduate as they’ll need to learn the basics. Afterward, a standard license to operate and own an HVAC small business should run no more than $200-$300 dollars per year. However, depending on which state one chooses to operate in, additional costs and restrictions may be placed before an actual license is granted to the requesting party. It’s best to research state laws and regulations before applying for a license to avoid rejection and red tape.

Tools of the trade
When working in a business that deals with a high risk of electrocutions, burns, fires, and other mishaps, insurance should always be the first service bought. If a major accident occurs, within a residential or commercial space, and the HVAC company doesn’t have insurance… The business owner is basically liable for all damages. To avoid this scenario the average business should always make sure to get more than $300,000+ of insurance, as that price range has been proven to be the most ideal in paying for household disasters and botched jobs. If adding other employees becomes a reality, workers’ compensation insurance should be bought as soon as possible to ensure every worker is cared for if an injury occurs. Once all insurance is paid, buying items like safety goggles, first aid kits, shoe covers, flashlights, pressure gauges, helmets, foil duct tape; carbon monoxide detectors, emergency contact cell phones, coil fin tools, refrigerant leak protectors, van, and other goodies can make most tasks safer and somewhat easier.

The market
The HVAC business is extremely competitive in the current market since more and more people find it a worthwhile endeavor that doesn’t require much input to gain a favorable output. To stand out and be heard, business owners need to be tech-savvy, creative, and willing to push marketing campaigns toward a broader audience so they don’t fall into that under-the-radar category. The best-proven strategy deals with networking, the internet, word of mouth, print media, and visual representation on the streets. A smart business owner should be able to produce and steadily update a Facebook page that lists and describes the company’s start-up, goals, main services, contact information, and any other extra information the owner desires. Traffic won’t magically hit the Facebook page online. So, it’s best also to run tangible paper ads, short radio ads, post flyers near home improvement stores, and advertise on the company van. The key here is to be creative and push the envelope since people make decisions based on what they see the most.

Unlike marketing, there is no set way to network when building a small business within a niche field. The idea behind networking is generally to interact with people, talk to them about common interests, occasionally name-drop the HVAC business of choice, and casually end the conversation on a good note. That person will eventually meet another person who might need assistance from an HVAC business, and the name is dropped once more. By being friendly and not aggressively pushing the business, future clients don’t feel like they’ve wasted time on a sales pitch. The name-dropping technique works even better when free service is rendered in exchange for positive reviews since a customer is more likely to brag about the generous gesture to a friendly face time and time again. Networking in present times stands to be the cheapest form of marketing, as well as the most beneficial since home improvement stores are always willing to partner up with a business that is well-known within the community. Usually the better the reviews and ratings, the better discounts a small business shall see from a sponsorship.

So in general, while starting and operating an HVAC small business isn’t rocket science, it requires intense thought and dedication before profit becomes a leading factor. An individual must be willing to work long hours and abide by state laws and regulations to avoid harsh penalty fees and bad business reviews. Marketing and networking should always be an ongoing routine until the company steadily shows a faithful client list.


A humidifier is used to increase the moisture content in the interiors of a home. There are many types of humidifiers, including a bypass, powered, steam and others. In this article, you will learn more about bypass humidifiers. Just like all other humidification gadgets, a bypass type should be regulated using an item called a humidistat. It is usually attached to the return air duct and can be integrated into the thermostat. Bypasses are very common gadgets and their price range is between three hundred and fifty dollars to five hundred and fifty dollars. Some of the best options use hot water and are best used on a forced-air furnace as the key heat source. Since the installation of this item is not all complicated, some of you can try it out. The following steps describe the procedure for installing a bypass humidifier:

Choose where you want to install the item and the position should be on the return ducting part of your HVAC unit. Grab your pattern and fix it in place with tape. As you do this, ensure the template is positioned properly and then draw the opening to be cut. Take away the pattern/template, and now use the trace to cut an opening in the ductwork. Dismantle your bypass humidifier up to the housing, pick up the housing and place the opening you have just cut. Attach it using metal screws via the already-formed slots. This will depend on the humidification unit you have purchased. Some have clips for attaching them to the ductwork.

Next, you must cut another opening in the supply plenum where a six-inch pipe starter collar should be mounted. Using the six-inch pipe start collar mentioned above, connect the supply plenum to the humidifier opening. At the same, install another six inches damper in the ducting and mark its position. Now, it is time to return all the components of your bypass humidifier into the housing. You have to do this correctly to avoid any repeat jobs later on. Attach the water supply tube to the upper part of the water panel and fix a twenty-four-volt transformer to the side of the air handler. Just ensure that the position you install will be convenient for wiring.

Complete the wiring process on the high voltage section of the transformer and then mount the humidistat above the humidifier. The work of the humidistat is to analyze how humid the air is in a given area. Complete the wiring process on the low-voltage section of the transformer. If you are unsure how this is done, refer to the producer’s instructions for different types of heating sources. Next, you want to fix the drain tube to any other operational drain location in your home. Check if your humidifier has a saddle valve attached to a metal water line. Since it is self-serving, the water line should fill as you tighten the valve.
