How to Prepare Your Home for the Seasons

    • Prepare Your Home for the Spring

    • Spring into action and be prepared for summer!

      • Chemically clean your condenser coils
      • Remove leaves from your condenser
      • Trim branches and shrubs from around the condenser
      • Clear the drain line to prevent water damage
      • Have your unit professionally cleaned
    • Lower that power bill!

      Depending on the size of your home, you can save 3% on your cooling costs for every degree you raise your thermostat in the summer. Raising the thermostat from 73 to 78 degrees can mean savings of up to 15% in cooling costs!

    • Prepare Your Home for the Summer

    • Temperatures are rising, Stay cool!

      • Keep your thermostat at 78 degrees to save money
      • Change your filters often
      • Make sure bees or ants have not built nests in your condenser
      • If the unit suddenly stops working check your breaker then call a professional.
    • Check your Fan Man!

      Make sure your fan is spinning clockwise. This will create a wind-chill effect. Turn your ceiling fan off when you exit the room. Fans cool people not rooms.

    • Prepare Your Home for the Fall

    • An ounce of prevention...

      • Change the filters before the system fails
      • Check the batteries in your thermostat once a year
      • Clean sticks and leaves from around the condenser
      • Have the furnace inspected before it's put to use.
      • Clean your drain lines
    • Batteries can be the culprit!

      Change the batteries in your digital thermostat annually: People forget that their digital thermostat has batteries in it. If you get in the habit of changing the batteries annually, you can eliminate a no-heat situation.

    • Prepare Your Home for the Winter

    • Our Winter Tips! Be Safe!

      • Have your furnace's heat exchangers inspected to ensure safety from carbon monoxide
      • Keep the system at 68 degrees to save money
      • Make sure your home is sealed tight so no air leaks out or in
      • Ensure your attic is properly insulated
      • Make sure that your system's gas lines and electrical system are checked for safety.
    • Saving energy saves you money!

      Set your thermostat at 65°-68° F during the winter while you're home during the day, and lower it at night or while you're away to 55°-58° F. Seniors and individuals with health problems may require a warmer setting
