What Does an HVAC Expert Do?

Residents of Mint Hill, NC, know that the seasons here call for heating and cooling systems that work all year round. If you are a homeowner in the region, the chances are you’ll need to hire someone to work on your HVAC system eventually. So what exactly does an HVAC expert do? 

An HVAC expert is someone who is trained in HVAC systems and equipment and provides several services related to these HVAC systems. HVAC technicians install, repair, and perform maintenance on heating and cooling systems. 

Some technicians are generalists, while others may specialize in installing, furnace repair, or another discrete area. Technicians may also specialize in different types of HVAC systems, such as solar technology or commercial units. 

Typically, an HVAC technician is responsible for installation, maintenance, repair, and even sales.


An HVAC professional is responsible for installing new HVAC systems in all types of residential settings. 

The installation process involves transporting the new system to the residence, installing it, and disposing of the old system. Installation jobs can take anywhere from a few hours to several days, depending on the size and the type of system.


As part of the installation process, HVAC experts perform a number of tests to ensure that the system will fit and work in its new location. They test the unit, its components and parts, and any electrical circuits to ensure that the system is functioning before they complete the job.  


Like many appliances, HVAC systems need maintenance. In order to keep a system in top working condition, it should be serviced once a year to ensure that all parts and components are functioning as they should. 

An HVAC expert is responsible for completing maintenance on a variety of heating and cooling units. Maintenance visits generally entail a detailed inspection of the system that includes testing parts, clearing the system of debris, testing the thermostat, and more. During a maintenance visit, the technician may:

  • Test pipe or tubing joints or connections
  • Check electrical circuits
  • Check electrical components 
  • Change filters
  • Clean ducts
  • Refill refrigerants
  • Adjust the thermostat
  • Adjust system controls 

If the technician uncovers any underlying issues during the inspection, they can then make the necessary adjustments. If more than a minor adjustment is needed, they will talk to the homeowner about any necessary repairs.


HVAC systems in Mint Hill, NC, are generally running hard all summer long. This heavy use means that the system withstands a lot and will naturally experience wear and tear. Years of constant use will eventually lead to the need for repairs.

An HVAC technician is responsible for diagnosing the problem with the system, determining what repairs are needed, then completing the repairs. Many repair jobs are straightforward, as most HVAC systems are similar and experience similar issues. 

However, some HVAC system problems aren’t so obvious and may require the technician to troubleshoot to determine the issue. Years of experience come into play when determining issues with a specific HVAC system.


As part of their routine job duties, HVAC experts may also engage in HVAC system sales. Sales duties could include advising a client on what type of system is appropriate for a replacement or working with a homeowner who is installing a new system in a new home they are building. 

Generally, homeowners aren’t familiar with the various types of HVAC systems, so they rely on an HVAC professional to help guide them when they’re considering a replacement or a system for a new build site. 

HVAC professionals draw on their experience to determine what type of system is appropriate for a particular home or construction project.

HVAC Technician Working Conditions and Hours

HVAC technicians generally work indoors in buildings but may spend some time outdoors to service outdoor HVAC components. Technicians are sometimes required to operate in tight spaces if they need to inspect ductwork or access an HVAC system that doesn’t have a convenient inspection point. 

While conditions are normally comfortable, occasionally, a malfunctioning HVAC system may create unusually warm or cold working conditions. 

Although most HVAC technicians work full-time with their core schedule during normal business hours, it is not uncommon for technicians to work overtime or during odd hours. HVAC breakdowns don’t always happen at convenient times, so professionals must be ready to service systems after hours and on weekends. 

In addition, during unusual weather events or storms, many people in a community may need service at the same time. This increased demand means that technicians may be expected to work overtime.
