HVAC stands for Heating Ventilations and Air Conditioning. It is the complicated system that helps you condition the air inside your home regardless of season and outside temperatures.

A HVAC is primarily composed of three parts: the indoor thermostat/unit, the outdoor unit and the duct system. All of these need to be properly maintained, in order for your HVAC system to function properly. Thus, a HVAC system can last for 15 to 25 years. Therefore, it is very useful to understand how it works.

The outdoor unit is typically visible outside your home. The refrigerant used by the indoor unit comes from the outdoor unit, and this the part that most people are familiar with. This unit contains a fan for cooling the refrigerant.

The indoor unit has a filter for both heating and cooling the air. Blowers, pans and coils sometimes need cleaning, so make sure you check them from time to time.

Ducts have the role of removing heated or cooled air. This part is also responsible with the quality of the air that enters your home, and therefore is involved in the ventilation process of your home. Without the duct unit, the air would become stale and unwanted odors would remain inside for a longer time.  It’s important to have a furnace repair Denver CO technician service your furnace as well as all the units in your HVAC system.
