Hvac attic filter.

Changing the filters in the hvac unit.
Most updated central air conditioned homes have a new air conditioner split system meaning the ac is broken up into parts.
So why put an hvac system up in the attic at all.
This arrow needs to point in the direction of your hvac s airflow.
Hidden away in your basement or attic the air filter in your hvac system is something you probably don t think about much.
Find the right filter size.
The air handler is the large metal box containing the fan and fan motor.
An outdoor unit which houses the fan condenser and compressor and an indoor unit which holds the evaporator and fan.
Typically the unit would be found in a basement an attic or sometimes in the back of a closet.
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.
Your ac s air filter is usually found in these 2 places.
Return vent with grate in place on the left and open return vent without the grate where you can see the filter and ductwork on the right 2.
Change the air conditioning or heating system air filters every month when the air conditioning system is in operation.
The air filter is usually located in the return air duct or blower compartment before the return air reaches the air handler.
Make sure you find all of the filters as some systems have multiple filters and even multiple types of filters installed such as a fiberglass or pleated paper filter a washable filter and an electrostatic air cleaner.
But a good air filter keeps your furnace and central air conditioner.
Air filters come in all different sizes and range from about an inch thick to a few inches thick.
In this case your air filter is most likely located right next to your furnace or air conditioning system air handler.
