Steps for Changing AC Filters

It might seem very easy to change your air conditioner’s filter, but there are some things to consider before and after changing AC filters. Let us discuss the steps first, then move on to the rest of the topics.

Get the necessary equipment.

A few essential tools are needed to perform the task of replacing AC filters correctly. Get a replacement air filter that fits the specs on your unit, a screwdriver in case you need it, and a vacuum cleaner so you can clean up afterward. Although not necessary, gloves help keep your hands clean while working.

Power Down Your AC

Keep safety first and turn off the electricity to your air conditioning system before making any changes. The main electrical panel, or disconnect switch, is typically located close to the outside unit. Make sure everything is off by flipping the switch.

Hunt Down the Filter

Depending on your arrangement, your AC filter may lurk in many locations. Look behind the return air grille, into the return air duct, or inside the air handler cabinet. If in doubt, pick up your handbook and quickly peruse its contents.

Say Goodbye to the Old Filter

Your previous filter has served its purpose, so say goodbye! The grille or cover keeping it in place should be carefully removed. Depending on your system, you might have to slide it out or unscrew it. Note which direction the old filter’s airflow arrow points.

Toss Out the Trash

New and improved, let the old go! Throw away your disposable filter by throwing it in the trash bag. If it is reusable, take care of it according to the manufacturer’s recommendation. Ensure it’s out of sight and out of mind in either scenario.

Spruce Up the Surroundings (Optional)

It’s time to do some fresh cleaning! Look around the filter area and use your reliable vacuum cleaner to kill dust bunnies. The task is significantly more accessible when the workplace is organized.

Slide in the New Filter

Now for the exciting part: installing the new filter! Ensure the airflow arrow points correctly when you slide it into position. It should be as tight as a bug, with no openings for air to scuttle through.

Add Cover Back On

It’s time to hide your filter now that it fits tightly, like an issue. Make sure everything is perfectly aligned before replacing the cover or grille. Depending on how you have it configured, give it a little push or screw it in firmly.

Flip the Switch

Now that everything is back where it belongs, turn on your air conditioning system again. Return the switch to the “on” position by going to the electrical panel or disconnecting it. Await the sensation of that refreshing wind once more!

Set Yourself a Reminder

Finally, just as importantly, remember to give yourself a small reminder for when you need it. Make a point to check your filter frequently, whether it’s on your phone, your calendar, or a sticky note. You should replace it every one to three months, depending on how often you use your air conditioner and how dusty your home is.


Although replacing AC filters may seem like a bit of an operation, we assure you it is a game-changer. By adhering to these ten simple procedures, you can maintain cool, clean air and an efficient air conditioning system. Experts check air filters prior, showing their significance during an AC repair or service. Try it now, and bask in the satisfaction of a job well done! You’ll be grateful to your lungs and your house for it.

Do air filters help with efficient heating?

By capturing dust, debris, and other particles that may impede airflow, air filters are essential in energy-efficient heating. A clean filter allows the heating system to operate more efficiently and distribute warm air throughout your house, eventually increasing heating efficiency.

What should you consider before changing the AC filter?

Consider your AC filter’s size, kind, and compatibility with your unit before replacing it. For information on how often to return, consult the manufacturer’s guidelines. To choose the proper filter efficiency, evaluate the amount of dust and other pollutants in your house as well.

Does my AC filter need replacing?

If there is obvious dirt and particle accumulation, lower vent circulation, higher energy bills, and decreased cooling performance, it’s time to replace your AC filter. It is advised to do routine inspections every one to three months to guarantee peak performance and indoor air quality.

What happens if your AC filter is dirty?

An accumulation of debris, dust, and pet dander on your air filter limits the airflow into your air conditioner and puts stress on the blower. Your home may have hot and cold areas due to the decreased air movement, making it more difficult and expensive to achieve the ideal indoor temperature.
