  • Can you see discoloration on your condenser’s grills?
  • Have you recently had several power outages?
  • Does your thermostat cycle on and off too frequently?
  • Has ice has formed on your outside unit?

Tips To Keep Cool On The Hottest Days

Even the best system can’t overcome issues of poor insulation, or extreme heat. On those super hot days of summer, there are a few things you can do to help your AC run more productively:

  1. First – and always – check your filters.Are they clean or do they need to be replaced?
  2. Close window blinds and curtainsLimiting sunlight from coming in, will go a long way to keeping your energy bill down, and your home cooler.
  3. Limiting opening outside doors.The more warm air you allow in, the more cool air you allow out. Think of it as costing you money every time you open that front door. Be extra careful between the hours of 10AM-2PM – when the sun is at its hottest.
  4. Give your AC unit outside some shadeProtecting your system from the sun’s heat, gives up to a 3% boost to the efficiency of your system. Be careful that you are still allowing plenty of airflow around the unit.
  5. Look for gaps and fill them.Is weather stripping on your doors broken or missing?
    Is there a gap between the bottom or the top of the door and the frame?
    Do all your windows close and seal tightly?
    Is one room substantially hotter than another?
  6. While you are away keep your AC between 78-80 degreesIf you raise the setting higher than 80 degrees on hot days, when you return, it will put a higher load on your system and it will take longer to get your home to a comfortable temperature.
