Heating and Cooling 101: What Do HVAC Contractors Do?

When it comes to furnaces, boilers, air conditioners, and the like, there’s no one better to turn to than an HVAC contractor. HVAC contractors rule the domain of heating and cooling and offer a number of services to both home and business owners. 

Wondering what exactly HVAC contractors do? Then read on for the details below. 

Install HVAC Systems

One of the primary responsibilities of HVAC contractors is to install HVAC systems. HVAC systems are machines that help control the climate in a building. Some of the most commonly used HVAC systems include the following. 

Central Air Conditioner

A central air conditioner is air conditioning that makes use of a duct system. The cool air is generated in one area and then pumped through the ducts so that it can reach different areas of the building. 

Central AC is used on both houses and commercial properties. Due to the fact that it requires a duct system, its installation is generally fairly extensive. 

Ductless Air Conditioners

While central air conditioning is the most popular option, another form of air conditioning has grown in popularity as of late: ductless air conditioning. This includes the installation of a single unit, one side of which contains the AC condenser and the other side of which contains the AC blower. 

The unit is mounted on a wall and is just big enough to provide cooling to a single room. Ductless air conditioners are most typically used in situations where only a room or two require AC. That said, it is possible to install a ductless AC unit in every room of a house. 

Heat Pumps

Heat pumps make use of geothermal energy as a means of both cooling and heating their respective homes. If you’re looking to do both with a single system, this is the system to choose. 

When HVAC contractors install heat pumps, they must take great care to install them in the correct area of the house. Because they rely on geothermal energy, their placement can make or break their functionality. 

When installed correctly, heat pumps are extremely efficient and can save their users substantial amounts of money. Just be sure to choose a reputable HVAC contractor. 


When it comes to heating the home, no HVAC system is more popular than the furnace. Furnaces come in both gas and electric models and are generally quite efficient in performing their tasks. 

HVAC contractors are well-versed in the installation of furnaces and are capable of installing them in a proper and safe manner. For this reason, when installing a furnace, it’s always recommended that you utilize the services of a heating and cooling specialist. 

Keep in mind that, like central AC, furnaces make use of a duct system. As such, their installation is quite extensive. 


Some homes use boilers to obtain heat. Boilers heat water to exceedingly high temperatures and then pass it through a series of pipes. These pipes radiate heat and essentially encompass rooms with warmth. 

The installation of boiler systems requires not only the installation of the boiler itself but the installation of the pipes as well. As such, like central AC and furnace installation, boiler installation is a big project. 

HVAC Repair

While a good deal of an HVAC contractor’s work includes HVAC installation and HVAC replacement, HVAC contractors also deal in HVAC repair. HVAC systems are fairly resilient in their operation. However, they do suffer impairment from time to time. 

For instance, something might get stuck in your air conditioner condenser, causing damage to its impeller. If so, your HVAC contractor will have to open the condenser up, remove the offending item, and then probably replace the impeller entirely. 

You could also have a problem with carbon monoxide leaking out of your gas furnace. This is a potentially deadly problem that needs to be rectified immediately. Again, your HVAC contractor will be able to assist. 

Other problems you might encounter include broken belts, diffused pilot lights, dirty ducts, and dirty internal components, to name just a few. In any of these cases, your local HVAC contractor can help you. 

It is important to note that your HVAC system will likely suffer an impairment at some point. Rarely does an HVAC system make it from the start of its life to the end of its life without needing a repair of some kind. So, save money for the occasion and ensure that you’re able to pay for the necessary repair services whenever they’re needed. 

HVAC Maintenance

If you want your HVAC system to last as long as possible and to perform to the best of its capabilities, you need to maintain it. This includes changing its air filter, cleaning its internal components, tuning it up, and more. 

Of course, as a busy person with a lot on your plate, you might not have the time to do all of these things. In fact, you might not even know how to do them. This is when it’s time to call up an HVAC contractor. 

HVAC contractors know everything there is to know about HVAC maintenance. Not only can they swap out filters and clean ducts, but straighten the fins on air conditioners, inspect for irregularities within the system’s structural components, and more. 

Generally speaking, it’s good to have your system inspected by a professional HVAC specialist either yearly or bi-yearly. Your HVAC contractor will not only assess the system to ensure that everything’s alright but will also make small repairs as needed. 

In fact, some manufacturer warranties even require that you have your system maintained by a professional. So, if you want to keep your warranty valid, schedule that appointment!
