Improve Your Cooling Equipment and Beat the Heat

Make a Cool Change to ENERGY STAR

Nearly half of the average home's energy bill during the summer goes to cool the home. If your cooling system's more than 10 years old, now is the time to consider upgrading to a new unit that has earned the ENERGY STAR. Older units may not cool efficiently, costing you more than they should on your energy bills. And, when you use less energy, you help protect the environment. In fact, if just one household in ten bought ENERGY STAR heating and cooling equipment, the change would prevent 17 billion pounds of air pollution.

If sized and installed correctly, and supported by a properly sealed duct system, ENERGY STAR qualified heating and cooling equipment

  • can save you up to 20 percent on your annual energy costs;
  • will use 25 to 40 percent less energy than a new conventional system.

Consult our "Time for a Change" Cooling Checklist PDF to find out if it might be time for you to make a change.

Buy High Quality Cooling Products

When you purchase cooling equipment that has earned the ENERGY STAR, you know that it meets strict energy efficiency guidelines set by the US Environmental Protection Agency (EPA), with no compromise on quality. When you use less energy, you help to protect the environment while saving money on your energy bills.

Install Energy-Efficient Products

Central Air Conditioners that have earned the ENERGY STAR have a higher Seasonal Energy Efficiency Ratio (SEER) than standard models. The higher the SEER, the more energy and money you will save on energy bills. ENERGY STAR qualified central air conditioners use 25 to 40 percent less energy than new conventional models.

Air-source heat pumps remove excess heat from indoor air by pushing it outdoors. An air-source heat pump that has earned the ENERGY STAR is at least 20 percent more energy-efficient than a standard unit.

Geothermal heat pumps use the ground instead of outside air to heat and cool the home. A geothermal heat pump that has earned the ENERGY STAR is at least 30 percent more energy-efficient than a standard unit.

Programmable Thermostats that have earned the ENERGY STAR allow you to pre-program up to four settings to consistently control your home's temperature on weekdays and weekends, saving you approximately $100 a year in energy costs — while simplifying your life.

Seal Your Home

Sealing your home “envelope” — the outer walls, ceiling, windows and floors-can help increase the energy efficiency of your home. This includes adding insulation, especially to the attic; sealing air leaks to stop drafts and get full performance from your insulation; and, choosing ENERGY STAR qualified windows when replacing old windows.

Effective air sealing, combined with the right amount of insulation, can save up to 10 percent on energy bills. Energy used in our homes often comes from the burning of fossil fuels at power plants, so sealing your home helps protect the environment. Learn more about home sealing.

Seal Your Ducts

When you upgrade to energy-efficient cooling equipment, be sure to properly insulate and seal the ducts that deliver your system's cooled air. Eliminating leaks increases your system's efficiency and can save you 10 percent on energy costs each year. Download Duct Sealing Fact Sheet PDF.

Find Experienced, Licensed Contractors

Every year, you should have a licensed contractor do a check-up on your cooling equipment to test its performance and energy efficiency. Having a pre-summer inspection is best, as it can prevent future problems and costly repairs at the height of summer when product demand is high and supply is low.
