How to change your air conditioning filter (5 easy steps)

Services for Real Estate Pros with HomePointe



1. First find the air filter. So, where is the air filter? In an air system, there is supply air and return air. The air filter is always in the return air duct. The return air is where it pulls in the air from inside the house. This is often found in your hallway and is the largest of the vents in your home.



2. Now, turn off the air system. There are 3 places to turn off the air unit: We suggest turning the system off at the thermostat (temperature regulator). The reason the power must be off is because it’s safest for you and to prevent the older air filter dust from getting in the air unit.



3. Decide the correct air filters size and filter type. There should be a number label in the air filter side, it looks something like this: 20x20x1, 8x16x1 etc.   Choose which air filters are best for your home. There are air filters that collect dust mites, pollen, tobacco smoke, spores or viruses. Any filter will do, so long as one is used and changed every 3 months. Economy filters can be purchased for under $3.00 at your local hardware store or a store such as Target.

4. Remove the old air filter. Clean dust off of the metal grill with a dusting cloth and be careful when removing to not accidentally dump older air filter dust in the unit or on yourself.   Before you put in the new air filter there should be an airflow arrow printed on the outer frame of the air filter. This arrow shows which way to insert the filter.



5. After inserting, close the metal filter grill and reattach accordingly. Now that your done we recommend marking your calendar 3 months from the date you changed the filter, a reminder to change it again.
A clean filter is healthier, saves you money on your energy bill, and protects the most expensive appliance in your home.







Always follow the proper installation instructions on the package… HomePointe is not responsible for any air filters improperly used or replaced.
