10 Tasks You Can Do to Improve Central A/C Efficiency

Posted: June 2, 2025

Reduce Your Electricity Bill During Summer

Prolonged heat waves can result in shockingly high electricity bills during the summer months. However, there are easy yet important energy conservation tasks you can do that could add up to impressive savings over time. With that in mind, our team has compiled a top ten list of things you can do to improve your home’s energy efficiency during the summer.

1. Add a ductless system: This is an energy-efficient way to target certain areas of your home with cool air. These units can be installed as supplemental cooling sources in your home’s “hot spots.” This may allow you to turn down your central A/C in the rest of the house, saving energy and money.
2. Get annual maintenance on your A/C equipment: Regular air conditioning system maintenance won’t just keep your equipment running more efficiently, it will also help reduce repairs and lengthen the life of your cooling equipment.
3. Have your ductwork checked: If we find flaws in your ductwork, our proven duct-sealing service will improve both the air flow and indoor air quality in your home. Sealing your duct work could also save you up to 30% on your annual energy bills.
4. Use a programmable thermostat: Run your home’s temperature slightly warmer when no one is home or you’re asleep and you can expect to save money on air conditioning bills for each degree you raise the thermostat. You can save as much as 10% a year on heating and cooling by simply turning your thermostat back 7°-10°F for 8 hours a day from its normal setting, according to the U.S. Department of Energy.
5. Save money with ceiling fans: These fans are a great complement to your central A/C. With fans circulating cool air, you can raise your thermostat by about four degrees with no loss of comfort.
6. Check air filters: A dirty air filter cuts airflow, causing your air conditioner to overwork (and you to overpay for energy). Check your air filter a couple of times during the cooling season, replacing or cleaning it when needed. Refer to the manufacturer’s guidelines for proper filter maintenance.
7. Don’t run heat-generating appliances during the hottest part of the day: When you use appliances like stoves and clothes dryers, you’ll increase the overall temperature inside your home. Whenever possible, limit their use to cooler parts of the day.
8. Block the sunlight: Close your blinds, drapes or curtains during the day to block sunlight. This helps to reduce the effects of solar heat, which can make your air conditioner use more energy.
9. Insulate: Poorly insulated homes allow summer heat to enter, which needlessly strains your A/C system and raises your cooling expenses.
10. Replace your old A/C system: Home air conditioning systems lose efficiency over time, even when well-maintained. Replacing an air conditioning system that’s 15 years old or more with a high efficiency replacement system could save you up to 30% on annual cooling expenses.
