As the temperatures rise, you may want to turn your air conditioner up full blast to enjoy the cool air. It’s best to give your AC a check-up before you do so.

Window unit air conditioners need regular maintenance to keep performing at their peak. With some simple DIY care, you can help keep your energy costs down and extend the life of your air conditioner.

However, you may still need to call a professional repair service like West Coast Chief from time to time for the maintenance that you can’t do DIY.

1. Clean the Coils

Coils are responsible for transferring heat, and if they’re clogged with dust and dirt, your air conditioner will have to work harder to cool your home.

To clean the coils, you’ll need to:

• Turn off the air conditioner.
• Remove the front panel of the unit.
• Clean the fins with a soft brush (a vacuum attachment will also work).
• Wash the coils with a foaming coil cleaner or a solution of water and vinegar.

2. Clean the Filter

A dirty filter can restrict airflow, reducing the efficiency of your air conditioner and increasing your energy bill.

To clean the filter, you’ll need to:

• Remove the front panel of the unit.
• Take out the filter and wash it with soap and water.
• If the filter is damaged, replace it with a new one.

3. Clear Debris from Around the Unit

If your air conditioner is located near trees or other plants, it’s important to clear away any debris that could fall on the unit and block the vents.

• Remove any leaves, twigs, or other debris from around the unit.
• Trim back any branches that are hanging over the unit.

4. Straighten All Fins

The fins help transfer heat. Bent fins are inefficient fins.

To straighten the fins, you’ll need a fin comb (available at most hardware stores).

• Turn off the air conditioner.
• Remove the front panel of the unit.
• Gently comb all the fins in one direction.
• Apply subtle, slow pressure to avoid damage.

5. Keep It Covered

When your air conditioner is not in use for extended periods (i.e., fall and winter), cover it to protect it from the elements and help it last longer.

You’ll need a tarp or heavy-duty plastic sheet and a pair of scissors.

• Gather the tarp around the air conditioner to cover it completely.
• Cut a hole in the tarp for the power cord to pass through.

6. Schedule an Annual Tune-Up

Even if you perform all of the above maintenance tasks on your air conditioner, it’s still a good idea to have it professionally serviced once a year. This tune-up will ensure that your air conditioner runs efficiently and prolong its lifespan.
