Save on energy this summer


Maintaining your air conditioning can mean savings not only in energy, but also in cold cash.

Here are some tips from Palmetto Electric Cooperative:

  • Set thermostats to 78 degrees in summer
  • Run ceiling paddle fans on medium, blowing down, in summer
  • Change HVAC filters monthly.
  • When installing new air filters, make sure they are facing in the correct direction. (Look for arrow on side of filter.)
  • Keep windows locked; they seal better.
  • Insulate electric wall plugs and wall switches with foam pads.
  • Caulk along baseboards with a clear sealant.
  • Caulk around plumbing penetrations that come through walls beneath bathroom and kitchen sinks.
  • Caulk electrical fixture wire penetrations at the top of the interior walls.
  • Close shades and drapes during day to help keep heat out during summer.
  • Make sure your attic access door closes tightly and insulate attic access door. Verify blown insulation in your attic has not shifted over into your soffit area, blocking your soffit vents.
  • Do not close off unused rooms that are conditioned by forced-air systems.
  • Do not close supply air registers.
  • Ensure return air grilles are not blocked by furniture or bookcases.
  • Make sure youre windows and doors are properly weather-stripped.
  • While outside, verify soffit vents in roof eaves allow for free air passage to keep attic cooler in summer and dryer in winter.
  • Do not use roof-top power ventilators for attic exhaust as they may evacuate conditioned air from your home.
  • Have your HVAC system serviced once per year by a NATE-certified technician. (Visit to find one.)
  • Ensure floor registers are not blocked with rugs, drapes or furniture.
  • Ensure your outdoor heat pump/air conditioning unit’s coils are kept clean and free of debris.
  • Outside your home, caulk around all penetrations including telephone, electrical, cable, gas, water spigots, dryer vents, etc.
  • Caulk around storm windows.
  • Verify your supply air duct “boots” (behind supply air registers) are caulked to your ceiling or wall sheetrock, or flooring.
  • Verify all outside doors and storm doors close and seal tightly.
  • In two-story homes serviced by one HVAC system, a paddle fan at the top of the stairs can push down hot, second-floor air.
  • Install 15 minute, spring-wound timers on bathroom ventilator fans.
  • Always run your HVAC system fan on “AUTO.” Running it on “ON” uses more electricity and can decrease your air conditioner’s ability to remove moisture.
  • Keep your garage door down. A warmer garage in the winter and cooler garage in the summer will save energy.
