Spikes in your energy bills are common during summer, as your AC unit works hard to keep your home comfortable. Taking steps to reduce the system's workload can help lower your energy costs, allowing you to put that cash toward family outings, vacations, or financial needs. Here are a few ways to make your air conditioning unit more efficient.

How to Boost Your AC's Energy Efficiency

1. Change the Filter

One of the leading causes of reduced efficiency is a dirty filter. Clogged filters block airflow throughout the unit, forcing the blower fan to work harder to move the air. They also interfere with your system's ability to produce cool air, so your unit will kick on more frequently and stay on for longer periods. According to the Department of Energy, replacing a clogged filter with a clean one can lower energy usage by up to 15%. Change the filter every two to three months. 

2. Eliminate Drafts

Drafts in your home let warm air in and conditioned air out, and your unit will work harder to compensate for the air exchange. Seal gaps around doors and windows with caulking, and replace any weatherstripping that is torn, flattened, or otherwise damaged. Check your attic space for gaps in roofing or walls, and replace any insulation that has deteriorated or flattened.

3. Close Blinds & Curtains

The sun's rays can raise your home's temperature. Keep blinds and curtains closed during the day, especially on south-facing windows and when the sun is at its peak from mid-morning to mid-afternoon. If you don't mind losing radiant heat during winter, consider installing window film that blocks UV rays and heat, allowing you to enjoy natural lighting and views.

4. Clean & Shade the Outside Condenser

The outside condenser unit releases heat from your home into the outdoors, using a fan to cool the refrigerant in the coils before it's cycled back to the indoor unit. If it has limited airflow around it or is in direct sunlight, the fan will struggle to cool the coils adequately, drawing more power. To boost airflow, clear away debris, and ensure at least 2 feet of clearance on all sides, removing plants or tall grasses. Consider installing an awning for shade, but be sure it doesn't block airflow.
