How Does an HVAC System Operate?

The HVAC system in your house or business plays a significant role in your comfort and wellbeing. As heating and cooling technology have improved over the years, more of the newer systems pull fresh air from the outdoors instead of recirculating indoor air. As you can imagine, this helps increase indoor air quality.

It takes nine different components to provide three essential functions: heating, cooling, and ventilation. These nine parts include:

Air Return - The air return is where your HVAC system begins. Air gets pulled in, filtered, and circulated for heating or cooling. For best results, keep your air returns free from dust and debris to keep your system running cleanly.

Air Filters - Air filters take on the task of removing particles of dust, dirt, and other debris before the air gets circulated into your HVAC unit for treatment. Ideally, air filters should get replaced every 30 to 90 days to keep your unit running smoothly.

HVAC Exhaust - The exhaust system and vents get used to expel exhaust created by your HVAC system. To avoid the potential for blockages, check your vent stack or chimney flue every year.

Ductwork - The ductwork is what moves treated indoor air throughout your home or office. Much like filters and air returns, keeping your ducts free from dust, debris, and other contaminants improves indoor air quality.

Electrical Components - The electrical components in your HVAC are what keep it operational. If you're experiencing issues, calling for HVAC services in Arlington can help you get your system back on track.

Outside Unit - The outdoor unit is likely the part that comes to mind most when discussing your HVAC system. This portion of your heating and cooling system contains the fan that keeps the airflow and circulation running. Keeping this area clear from obstructions provides the best results.

Compressor - You'll find the compressor housed in the outside unit of your HVAC unit. The compressor turns refrigerant into a liquid from gas as it passes through the coils.

Coils - Also found in the outside unit. These coils use the refrigerant from the compressor to cool the air as it passes. Your coils should get inspected annually to prevent them from freezing up.

Blower - Your blower pulls in warm air using to keep your unit running efficiently. A clean fan helps to keep your HVAC system running optimally.

The heating system generally refers to the boiler or furnace used to heat the home. Instead of cooling, it heats the house during the cold weather months.
