Attic Ac Unit Filter Location

Changing the filters in the hvac unit in this case your air filter is most likely located right next to your furnace or air conditioning system air handler.

Attic ac unit filter location.

It s generally located in your attic basement closet or crawlspace. Look for a filter slot right where the return plenum contacts the blower fan assembly marked as air filter slot and yellow arrow in my photo. The air handler is the large metal box containing the fan and fan motor. You say you changed the two in the living areas suggesting that you have a dual zone system 2 floors.

The 2nd duct is the return duct that attaches to the return air vents and draws the stale air out of the house through the filter and conditions it again to return. So why put an hvac system up in the attic at all. There might be two removable front panels and you may have to lift the top one off first. Two large pipes or ducts extend from the package unit.

All central heating and cooling systems should have an air filter but the filter can be harder to locate on some hvac units than others. Well mainly it s a way to save space. Most updated central air conditioned homes have a new air conditioner split system meaning the ac is broken up into parts. Typically the unit would be found in a basement an attic or sometimes in the back of a closet.

One is the conditioned supply air that serves the house with warm or cool air attaching to the vents in every room. Sometimes the air filter is behind the bottom front panel of the air handler. An outdoor unit which houses the fan condenser and compressor and an indoor unit which holds the evaporator and fan. The return air plenum on an attic or basement air conditioner blower unit will usually be a large metal enclosure about the same dimensions in width and height as the air conditioner blower unit itself.

The filter is probably at the air intake not in the furnace blower unit up in the attic. If you don t see a panel on or near the air handler indoor unit that has filter stamped on it then try checking these locations. Attic hvac systems save space. This air handler has a filter base under the unit.
