As the weather starts to warm up, you might be thinking about turning on your air conditioner for the first time in months. But before you do, it’s essential to ensure that your AC is in good working order. After all, the last thing you want is for your air conditioner to break down in the middle of a heatwave!

Luckily, you can do a few simple things to keep your AC running smoothly all summer long. This blog post will share an air conditioner maintenance checklist to help you get your unit ready for action. So without further ado, let’s get started!

Inspect and Clean the Unit Regularly

One of the most important things you can do to keep your air conditioner running smoothly is to inspect and clean it regularly. At least once a week, look at your AC unit and remove any debris, leaves, or other objects that may have gotten caught in or around it. In addition, be sure to check the coils and fins for dirt or debris build-up and clean them as needed.

Change the Filter Regularly

Another critical element of AC maintenance is changing the filter regularly. Depending on your filter type, you may need to change it as often as every month or two. Clogged filters not only reduce the efficiency of your air conditioner but can also lead to costly repairs down the road. So be sure to check your filter regularly and change it as needed.

Schedule Annual Maintenance Checks

In addition to regular inspections and filter changes, you should also have your AC unit serviced by a professional at least once a year. During these annual maintenance checks, a technician will thoroughly inspect your unit, clean all of its parts, and identify any potential problems. These maintenance checks have been vital in keeping your AC unit running smoothly and efficiently for years.

Keep the Area Around Your AC Unit Clean

Your AC unit needs room to breathe! Be sure to keep the area around your unit clean and free of debris, leaves, twigs, and other objects. In addition, trim back any bushes or trees that may be growing too close to your unit. Allowing your air conditioner to have proper airflow will help it run more efficiently and prevent potential problems.

Clean the Condenser Coils

One of the essential parts of AC maintenance is cleaning the condenser coils. These coils are responsible for dissipating heat, so keeping them clean and free of debris is critical. The best way to clean them is to use a coil brush and gentle cleanser. Brush away any dirt or debris, and then rinse with the cleanser. Be sure to let the coils dry completely before moving on.

Check the Freon Levels

Freon is a refrigerant that helps transfer heat from your home’s air to the outside air. If your AC unit is low on Freon, it won’t be able to cool your home effectively. You’ll need a professional to check and refill your Freon levels. However, you can check the pressure gauge to see if it’s low. If it is, call a professional as soon as possible.

Inspect the Ductwork

The ductwork is what carries cooled air from your AC unit into your home. If there are any leaks in the ductwork, cooled air will escape before it has a chance to reach your living space. To check for leaks, hold a piece of tissue near each connection point while the AC unit is running; if the tissue moves, there’s a leak that needs to be sealed.


By taking the time to do some essential maintenance on your air conditioner, you can extend its lifespan and make sure it runs smoothly. So don’t wait until it’s too late—use this checklist as a guide and get started on AC maintenance today!
