20 Tips To Save Energy And AC Costs


energy efficient home heating


Air-conditioning has long been a major energy waster. Although units are being manufactured with better intelligence and efficiency ratings there are still millions of old units in use. Here are some tips that will help save money and reduce CO2 emissions for no or very little investment on your part.

It is important to get the right size of air conditioner. Large units will waste a lot of energy and turn on and off frequently. Invest in an AC controller to optimize the efficiency of the unit and reduce cyling.

Many electrical appliances, such as motors, lights and electronic components generate heat that puts an extra burden on air conditioning. Turning off unsed appliances and lights will greatly reduce heat and consequently improve your AC cooling efficiency.

How To Reduce Your Air Conditioning Cost

Consider implementing some of the following no or low cost heat energy saving strategies:
  • Turn lights off when not in use. Electric lighting adds heat to a space that must be removed in the summer by air conditioning.

  • Don't block the supply air or return air ducts to the air conditioning system with furniture or drapes.

  • Keep doors open in all rooms cooled by a central air conditioning system.

  • The air conditioning system should be fully charged with freon so it will operate most efficiently when you need it.

  • Check your car and home air conditioning systems for freon leaks and repair them properly.

  • When the weather is nice outside leave the AC off and open the windows.

  • Use solar screens and film on south and west facing windows. It will reduce the cooling load of a building.

  • Clean air conditioning ducts in older homes to increase the efficiency of the air conditioning system.

  • Repair holes and broken seams in ductwork to be sure all the conditioned air arrives at the occupied spaces and is not lost in the attic or ceiling space.

  • Clean out bird nests and debris from attic louvers so that air can flow freely through the attic space. Your home will be cooler.

  • Exhaust all the hot humid air from the bathroom after bathing. Humid air puts a heavy burden on the air conditioning system.

  • Wear lighter clothing in warm weather and raise the AC thermostat.

  • Changing air filters for the air conditioning monthly during times of high use will keep the equipment working at peak efficiency.

  • A programmable thermostat at home can turn the central unit up a few degrees after you go to sleep in the summer and during the day.

  • Close off air vents and keep the doors closed to rooms that are seldom used to save on air conditioning and heating costs.

  • Use drapes and awnings to reduce the heat transferred through windows by closing them when a space is not currently in use. Even partially closed vertical or horizontal blinds help.

  • Install a thermostat to control the attic fan so that it operates only when the temperature is ten or more degrees above ambient.

  • Use reflective materials on the window side of draperies. This reflects solar heat when the curtains are closed and helps keep a room cooler during the summer.

  • Landscape shading of walls and roof will conserve on summer utility bills.

  • Install a replacement roof on your home that is light in color if the summers are extreme. Your air conditioning will work less to keep your home cool.

By implementing these tips, you will get definately get a lower air conditioning cost.
