Attic air handler filter.

Since the ahu is the central unit that moves the air throughout the ductwork it is important to make sure nothing obstructs the airflow through the air handler such as dirty or clogged air filters. This air handler has a filter base under the unit the air filter might be on top below or on the side of the air handler depending on what kind of air handler you have. If you changed the filter and the evaporator coil still continues to freeze you may have a refrigerant problem or worse. Your air handler consists of an evaporator coil blower motor air filter and the electrical and electronic components required to deliver enhanced levels of indoor comfort.

This allows the filter to clean the air coming from your house before it enters the hvac unit. Air handler filters may be located between the return air plenum and the rest of the air handler which contains a cooling coil for air conditioning or a heat exchanger for heating systems and also a blower fan that causes air to move across these components and out into the supply ducts. It s generally located in your attic basement closet or crawlspace. Having your hvac system in your attic isn t dire though you ll need to do some work to keep your air conditioner or furnace system running as efficiently as possible.

The air filter is usually located in the return air duct or blower compartment before the return air reaches the air handler. The first and possibly most important thing is to make a commitment to yourself to change your hvac filters regularly. Call your local phoenix hvac technician as soon as you can.
