Tips to get the most out of your system

Air conditioners maintain indoor comfort by removing heat and moisture from the air. As the weather gets warmer, air conditioning equipment has to work harder and will use more energy to maintain comfort conditions in your home. Consumption can increase significantly from one month to the next, even if thermostat settings are not changed.

You can also expect operating costs to increase if your air conditioning equipment is not properly serviced and maintained.

Remember these tips when you use your air conditioner.

  1. Keep the thermostat set at 78 or higher. For every degree you raise your thermostat above 75 degrees, you can save about five percent on your air conditioning bill.

  2. Clean or replace filters each month.

  3. Keep furniture and other obstructions away from return air grills.

  4. Have the air conditioning inspected or serviced annually.

  5. Keep the area around the outside condensing unit clear of grass and other obstructions.

  6. Use fans to increase your comfort at higher thermostat settings. An oscillating or ceiling fan uses about as much energy as a light bulb. Using a fan to offset your need for cooler air conditioner settings will save money on your cooling bill. Remember, fans don't actually cool the air; they just make you feel cooler. Turn them off if no one is in the room.

  7. Reduce solar heat gain by shading south and west facing windows during the summer.

Energy-saving air conditioning tips:

Humidity makes your home uncomfortable in hot weather. Save moisture-making jobs like mopping, dishwashing, laundry and bathing for early morning or nighttime. Set your thermostat on the highest comfortable setting. Raising the temperature just 2 degrees will reduce cooling costs by 5 percent...

Close the blinds, shades or draperies in your home during the hottest part of the day. Turn off unnecessary lights. Much of the energy from a light bulb is heat.
Make sure your attic is properly ventilated to relieve heat buildup caused by the sun. Plant trees to help shade your house. But make sure your air conditioner is kept free of any plant overgrowth that would interfere with air circulation.
Light colors on the outside of a house reflect the sun's rays, reducing the temperature inside. If your cooling bills are higher than your heating bills, consider a light-colored roof shingles when you must replace your roof. If you have central air conditioning, make sure your registers for supply and return air are not blocked by furniture or drapes...

Cook out or prepare cold meals to avoid heating up your kitchen. Place heat-producing appliances such as lamps and TV's away from your thermostat.


With the temperatures nearing the 100 degree mark, and the heat index already surpassing 100 degrees, it's time to think about routine maintenance for your A/C unit. As with any electrical appliance--remember to disconnect all power to your air conditioning unit before you remove the access panels to perform routine maintenance, and be aware that there may be more than one connection that you must disable. Do-It-Yourself Routine A/C Maintenance Check and change dirty air filters every month. A dirty filter makes your air conditioner work harder and costs you more money on your utility bill. Your indoor coil should be dusted. Use the soft-brush attachment to your vacuum cleaner to accomplish this task and make sure the coil is dry before you start. Make sure your outdoor condensing unit is free of any debris--keep grass clippings, leaves, plants, and other items away from your unit. Occasionally you should check the base pan which is located under the unit and remove any debris that has collected. Be sure the support for your outdoor unit has not settled and caused your unit to become unlevel. If you see that it is not level, you will need to re-level it to keep moisture properly draining out. When Your A/C Is Not Cooling Be sure your circuit breakers are on and that the fuses have not blown out. Check your air filters, and make sure they are clean and not obstructed by any debris. Make sure your thermostat is properly set to cool. Most service dealers recommend that you have your unit inspected and serviced by a professional at least once a year and many offer service contracts which cover seasonal inspections. Finding Air Conditioning Service Hopefully, the routine maintenance you perform will prevent a breakdown from occurring. But if you find yourself, on one of these sweltering summer days, caught with an air conditioner that is not operating properly, contact your regular service contractor or one of the following service providers.


BEN reminds you... Routine maintenance for your heating system, cooling system, and appliances is as important as changing the oil in your car. FILTERS: Dirty furnace filters can lead to more serious problems. A system running all time and not performing as normal is a sign of a dirty filter. Make sure you check monthly. THERMOSTAT: Always pick a temperature setting and leave it there. CONDENSORS: Any refrigeration equipment operating 10 to 20 degrees above operating temperature could be a sign of a dirty condensor. Check and clean as needed. Location of condensor on most household refrigerators is underneath in the front or rear. For all other refrigeration equipment the condensor is normally in the compressor area.
