How
Heating and Air Conditioning Systems Operate

Knowing your how HVAC Systems operate can be helpful in understanding the important role AC Filters and Furnace Filters play in the efficient operation of the HVAC system and how it impacts your indoor air.

Below is a drawing of the typical central heating and/or air conditioning system used in a home or small office. Often referred to as a "loop system", the air passes through the HVAC system, and is circulated in an endless loop.

The loop begins when air comes into the system through the return air ducts located throughout the building and into the ductwork. Air then passes through the ductwork and the ac filter or furnace filter and then into into the actual HVAC system where it is forced out into the ductwork and through the register vents into each room of the dwelling.

Each component of the HVAC system is designed for a specific function. All of the components except the ac filter and/or furnace filter are fixed. Consequently, the only way to significantly improve the quality of the air that passes through the HVAC system is through improving the quality of the ac filter and/or furnace filter.

(It is important to note that proper maintenance is crucial, including routine cleaning of the coils and other parts of the HVAC system and occasional ductwork cleaning. Be advised, this work should be performed by a licensed HVAC technician.).
