How Your HVAC System Works

How Your HVAC System Works

HVAC systems are a part of everyday life. Your HVAC system provides a comfortable temperature and air quality in your home. As a homeowner, it is important to understand the key roles of your HVAC system and how they operate.


The forced air system is the most popular type of heating system today. It uses a furnace to heat the air and distribute it through ducts and in-room vents.

Radiant heating systems use stoves or a boiler. They disperse heat via electric heating coils or hot water tubing.

Geothermal heating uses the constant ground temperature by absorbing the sun’s rays. It disperses heat for your home via a heat exchanger. Whichever type of system you have, it thankfully provides warmth for you and your family in winter.


Ventilation maintains your home’s indoor air quality. You can do this through mechanics, fans, and windows, or through a combination of the two.

Forced air systems distribute the air through an air filter. This keeps volatile organic compounds (VOCs), and allergens out of your home. You can also use air cleaners, air purifiers, humidifiers, and dehumidifiers. Ventilation can address breathing or allergy issues in the family throughout the year.

Air Conditioning

The refrigerant reaches the compressor as a low-pressure gas. It leaves as a high-pressure, hot gas, and moves to the condenser. The condenser converts the hot gas to a much cooler liquid. The fluid goes into the evaporator and evaporates into a gas. The AC sucks surrounding air to cool gas in the evaporator. Fans in the evaporator then blow the cooled air back into the house. The process starts all over when the gas goes from the evaporator back to the compressor.

Understanding your HVAC system prepares you to maintain it. You can determine what is missing and buy a new system if the time comes. Advent Air Conditioning is the comfortable solution for all your HVAC troubles. Call us today at (469) 240-5456!
