Who HVAC Contractors Are and What They Do

Ventilation and heating are important for every residential and commercial establishment. That is why heating, ventilation, and air-conditioning (HVAC) systems are installed in homes. Ventilation refers to how outdoor air is transferred to an indoor space either naturally or mechanically. This process removes stale air and maintains indoor air quality. Proper ventilation can also remove smoke, moisture that may have accumulated inside the home, indoor pollutants, and cooking odors. Moreover, it controls the level of heat in attics, crawlspaces, and basements.

On the other hand, heating is a process by which the temperature in an enclosed space is raised. This process is done with heating machines powered by gas, oil, coal, or electricity. The primary purpose of this procedure is to provide comfort to the occupants of a room. Still, it is also a popular method used for maintaining the structural, electrical, and mechanical systems of buildings.

Heating businesses and those involved in HVAC installations are crucial for the maintenance of ventilation and heating systems. These mechanisms can suffer from wear and tear and other issues that may need the expertise of HVAC technicians. These skilled workers provide three major services and include the following: installation, maintenance, and repair.


The installation of an HVAC system is a daunting process. Unlike some air-conditioning units, which can be installed through DIY, HVAC installations may require knowledge on regulations set by the local authorities regarding installation procedures. Also, it requires knowledge and expertise on tubing, ductwork, piping, and connecting to electrical supply. Installation may also require a thorough inspection of the area where the system will be fitted. If the area has an existing HVAC unit, it will have to be carefully removed before the new system can be installed. All these require the knowledge and expertise of authorized and licensed HVAC contractors.


The upkeep of an HVAC system requires more than just ordinary cleaning of the device’s parts. It also involves a thorough inspection of the entire structure, including checking the electrical lines, inspecting exhaust pipes, checking refrigerant levels, examining fuel connections, evaluating the condition of the condensate drains, and many more. Once all parts are examined, the technician will then have an idea of what needs to be done to maintain the unit or if repairs are required. For dirty systems, maintenance usually involves removing dust, pollen, vermin, insects, and debris that may have lodged inside the ducts, pipes, blowers, condensing units, and in other parts. The thermostat may also be recalibrated or repaired if the technician finds something wrong with it. In some instances, the moving parts in the HVAC unit may be lubricated to keep them working efficiently.

The condensing units, compressors, exhaust outlets, and other essential parts of an HVAC system may require repair if found to be damaged. The contractor will assess the extent of the damage and if repair is possible. If not, they may recommend replacing the parts or, in some instances, the entire unit.

Repairs are usually required during emergencies, such as the sudden breakdown of the unit. Sudden failure of the machine to do its function usually means faulty or damaged parts in the device.

An HVAC expert may recommend replacement of the unit based on the following assessments:

  • The system is too old to be repaired. HVAC systems over ten years old may no longer work efficiently despite the number of maintenance services. In such cases, a replacement is inevitable.
  • The system poses a hazard to the occupants. Sometimes, HVACs can malfunction, and instead of providing quality air to the occupants inside the home, they emit poisonous gas. Faulty and damaged parts may cause this. Some faulty units may also pose fire hazards to the home.
  • Constant repair is required. If the HVAC system is constantly requiring repair, it is time to let it go and look for a replacement. A new installation may cost lower in the long run than constantly spending on costly repairs.

The bottom line is that HVAC contractors can provide tremendous assistance when it comes to installation, repair, and maintenance. Different contractors may offer different services, though, so it is also important to do some research before hiring one. It may also help to ask for bids from different contractors before making a decision. This way, you can make a well-informed decision easily.

Other ways to know which contractor can be trusted is to know their reputation, verify their insurance, and check their licenses. Checking their previous work experiences may also help assess their practicability.
