But first, knowing how to find your AC filter is essential.
Follow this procedure to change your air filter at home.
How to Change Central AC Filter
Find the Filter location
In your house, the air filter is often located in a return duct next to the thermostat. Or, it’s probably close to the air handler cabinet for your AC system.
For most systems, however, the filter is located where the return duct meets the air handler. Nonetheless, in the unlikely event that you only have one and not the other, this is how each will appear:
- Return Ducts
This air conditioner features a grate on the ceiling, wall, or floor with slatted gaps that allow the air to travel through. They often have a larger vent size than your typical air duct.
To find a return vent, hold your palm or a scrap of paper up to the vent while the AC’s fan is turned on. If you feel a suction effect or the paper is drawn toward the vent, it’s a return vent.
- Air Handler
The air handler is a big metal box that houses the AC’s fan and motor. It usually resides in the basement or attic.
When you see it, search on the appliance’s left, right, top, or bottom to locate the changeable filter.
Sometimes, air handlers must be unbolted by hand or with a tool to reach the AC filter.
Once you’ve located either system, search for a slot in which an air filter should fit. Larger residences may have many units, each with its filter.
Get the Right Replacement Filter
Getting the correct filter size for your AC can be tricky. Although the filter size is usually labeled on the side of the filter, you can quickly get the measurements wrong.
When in doubt, the most straightforward approach is to ask your HVAC technician to get you a batch of suitable filters for your AC. Or, you can request them to show you the filter size information so you can buy them from your local hardware store.
Also, remember that you may want filters that go the extra mile. Keeping dust out of your AC may not be sufficient for you.
If that is your preference, invest in HEPA filters with a MERV rating of 10 or above.
They will enhance your home’s air quality by eliminating pollen, mold, and other potentially dangerous particles.
Replace Your Air Conditioning Filter
Follow these simple steps to replace your central AC unit’s filter and keep your unit running properly.
Unplug the power source
Your safety and that of your equipment are why this step is crucial. If you come into contact with live voltage, you risk getting electrocuted.
Also, running air conditioners might draw more dust and debris into the unit while you’re uninstalling the clogged filter.
You must turn off the electricity at the circuit breaker and the appliance itself.
Put on a mask and gloves
First things first: If there is even a remote possibility that virus particles or molds are in your environment, they might get lodged in your AC filter. Therefore, put on a mask and gloves while replacing the filter.
Take out the old filter
Just remove it from the slot that keeps it in place.
Examine the condition
Examine the AC filter’s condition once you’ve removed it. Does it seem stacked with debris and dust? If it’s clogged, there’s probably less light penetrating through if you raise it to the sky.
Depending on your brand, you’ll have to clean or change that filter. The best option is to replace it, even if it has been in use for a short period. Many things might influence how quickly your filters get clogged.
For instance, New York’s smog alone can reduce an air filter’s lifespan.
Dispose of the old filter safely
If there are impurities on the filter, throw it in a carrier bag and dispose of it in a trash can outside your property.
Clean the new air filter
Do you have washable or disposable filters?
Generally, a disposable filter features a cardboard canvas and a surface made of paper or fiber mesh. On the contrary, a permanent, reusable filter has a durable metal frame glazed with a unique coating to make it washable.
If you’re using a reusable filter, be sure to follow the manufacturer’s washing guidelines.
However, you’ll likely need to rinse it with water and let it dry thoroughly.
Or, in certain circumstances, you may vacuum the dust away.
Replace the old filter
All that’s remaining is to reinstall it correctly. On the filter’s frame, you’ll see an arrow showing you the direction in which the air should recirculate through the filter. That direction is toward the air handler system and away from the return air duct.
If you do it in the opposite direction, your air filter will malfunction.
That wasn’t so hard, was it? Now that you understand how to replace or clean an AC filter, set a monthly reminder, so you don’t forget.
Also, if your furnace’s filters are isolated from your air conditioner, don’t forget about them.
