What Does An HVAC Contractor Do?

HVAC stands for heating, ventilation, and air conditioning. The job of an HVAC is not only to cool and heat, but also to filter clean air throughout the building. Nearly every building in Charlotte, NC, has some sort of climate control system.

HVAC technology has improved significantly over the years, but it has also made the systems more complicated. There are many moving parts that all must work together to keep the appliance working. That’s where an HVAC professional comes in. 

If you are not familiar with HVAC technology, you may be wondering, what does an HVAC contractor do? HVAC contractors are specialists in HVAC systems and can perform maintenance, installation, and repairs. 

What Specific Work Do HVAC Technicians Perform?

HVAC professionals are trained to work on a range of HVAC systems, both commercial and residential. But what does an HVAC contractor do day-to-day? Read on to learn about the major service areas of HVAC technicians.


HVAC maintenance is a major part of HVAC work. Diligent homeowners schedule a yearly HVAC maintenance visit during which the technician will check ductwork, parts, and connections to ensure everything is working properly. 

During a maintenance visit, a technician can make adjustments or repairs if they find any underlying issues. They can also change filters and give the homeowner or business owner a status update on their system.


Even though HVAC systems are durable and designed to last for many years, most systems will eventually need some sort of repair. Sometimes parts go bad, the system can freeze up, or normal wear and tear can cause a breakdown. 

HVAC technicians inspect the system, identify the underlying issue, then perform the repair to get the system back to good working condition. In Charlotte, NC, many HVAC professionals have routinely replaced parts and a full set of tools with them at all times so they can perform many repairs on the spot.


Installation is one of the most important parts of HVAC training. If a system is not installed correctly, it can cause big problems down the road. During an HVAC installation, a technician will survey the installation area and take measurements to determine the appropriate size and system capacity. 

They will remove the existing system if there is one, then carefully install the new system. Finally, they perform a series of checks to ensure the system is in good working order before leaving.

Duct Cleaning and Repair

When you think of HVAC, you may think of the outdoor unit that powers the system. But a critical part of any HVAC system is the ductwork. All of the air that circulates throughout a home or business goes through the ducts. 

If the ducts are dirty or if they require repair, the whole system can be compromised. HVAC technicians often perform duct cleaning. They also inspect the ductwork and repair any faulty parts or leaks.

Indoor Air Quality

Many HVAC contractors are experts in indoor air quality. They can test the quality of the air inside a home or building and determine what level of allergens, pathogens, and other unwanted particles are in the air. They can then recommend solutions to improve indoor air quality, such as adding humidifiers, air cleaners, filters, and more. 

If you are looking for a nearby technician in Charlotte, NC, for indoor air quality assessment, just make sure that the HVAC contractor you choose is specifically trained in indoor air quality. Not every HVAC technician has the appropriate training.

Other Services

Just like other professional industries, there are areas of work that some HVAC contractors specialize in. For example, boilers and water-based or solar-based heating systems require a unique set of skills that only a specialist will have. 

What to Expect When You Hire an HVAC Contractor

If you’ve never hired an HVAC contractor, you may not know what to expect. While no two HVAC companies are the same, most of them have similar practices. 

Your HVAC contractor should be transparent and communicative as soon as you hire them. They should be able to work around your schedule and even give you an estimate for the work, depending on your situation.

When the contractor arrives, they should start with an initial inspection, then talk to you about next steps before performing any work. If your HVAC system does need repair, they will let you know a price estimate and how long the work will take. They will also walk you through exactly what is wrong and why it needs to be fixed.

Once the contractor has completed the work, they will give you a rundown of job and a status update on your system. If you hire a nearby technician, they will be there to support you after the work is done.
