Tip #1: Invest in regular maintenance

There’s a reason this tip is #1 on our list of ways to improve your AC's efficiency. Investing in annual AC maintenance is the best way to ensure that all parts of your system are working correctly and that your AC system is running as efficiently as possible.

When parts of your AC are worn-out or damaged, your AC system as a whole has to work harder to compensate. A quality technician will spot parts that need to be maintained, repaired or replaced so that your AC is functioning efficiently (and your bills are staying as low as possible).

Tip #2: Clean your air filter

Your AC cools your home by drawing in warm air, stripping away the heat, and then blowing the cool air back into your home. If your air filters are dirty, it is harder for your AC to suck air through them, limiting the supply of air and making your AC work harder to cool your home.

The solution? Check your air filter. If it looks like the filter on the right in the image below, it’s time to replace it. A good rule of thumb is to check and replace your filter every month during peak cooling season (the summer).

Tip #3: Turn up your thermostat

Turning your thermostat up a few degrees can help take the load off of your AC system.

According to Energy.gov, turning your thermostat up 7–10 degrees for 8 hours a day can increase the efficiency of your system and save you up to 10% in cooling costs.

An easy and efficient way to control the temperature in your home is to install a smart thermostat. With a smart thermostat, you can easily set your home’s temperature to follow a cooling schedule, so you don’t have to think about constantly adjusting your thermostat.

Tip #4: Keep curtains and blinds closed

Your home can absorb a lot of heat through uncovered windows and doors, especially if they are facing east or west. The hotter your home is, the harder your AC system has to work to cool your home.

To help your AC run more efficiently, you can reduce this heat absorption by keeping your blinds and curtains closed during the hottest parts of the day.

If you don’t have curtains, you can improvise by hanging towels or blankets over your windows during the heat of the day (light and medium colors usually work best).

Tip #5: Clean and open vents

Your AC needs a consistent supply of air to cool your home properly and efficiently. If your vents (both return and supply) are closed, dirty or blocked, they will limit the airflow to and from your AC system, making your AC work harder to produce cool air.

To help improve the efficiency of your AC system, clean your vents. You can do this by vacuuming around and inside the opening of vents.

It’s also important that vents aren’t closed or blocked by anything (like furniture). Why?

Your AC system is designed to deliver the right amount of air through each vent. When some vents are closed or blocked, it can throw off the balance of your AC system, making your AC work harder.
