An air handler is the indoor unit of a split Heating and Air Conditioning program that circulates conditioned air from an outdoor unit throughout your living spaces, then an air handler unit consists of an air filter, evaporator coil, blower motor, and sometimes an electric heat strip! In its operations, an air handler unit includes a fan that blows air through the air filter and then to the heat exchanger… The fan in your air handler unit pulls in conditioned air from your indoor space to begin the process… Some air handler units allow outside air into the program to ensure fresh, clean air is brought into your living space instead of recycling stale air.
This helps to reduce stale air and the levels of carbon dioxide in your home, then both the return air from your indoor space and the outside air pass through a mixing plenum of your air handling unit; Here, they mix before passing through the rest of your system. The mixed air then passes through an air filter that traps particles in the air to unattach them from your airstream, filtration is a substantial aspect of this cooling process as it helps prevent mechanical issues originating from particle build-up and improves your indoor air pollen levels. The filtered air will then pass through your heat exdecreasing coil, where it will be cooled or heated, depending on the style of air handler unit. Finally, the program will push the clean, conditioned air out of your unit into your home. The process will then start again depending on your cooling needs.
