Tips for Maintaining Your Air Conditioning Unit

3. Air Conditioning Checklist

1. How Does Air Conditioning Work?
Air conditioners work by removing heat and moisture from the air. As weather gets warmer, your air conditioner has to work harder. In the summer you can reduce solar heat gain by shading with awnings or trees on the eastern, southern, and western sides of the building.To keep your home from getting hot in the first place, reduce the amount of heat generated inside by inefficient appliances, lights, etc. Make sure that windows are adequately sealed so that there are no leaks, and reduce solar radiation with window coverings. Adequate insulation in the rest of the house will help maintain a comfortable temperature, and elastomeric roof coating can reduce your air conditioning load. Make sure your unit is efficient; the highter the SEER rating, the more efficient the unit.We sell 10, 12, 13 & 14 SEER units. We recommend a unit with a 12 SEER rating for more efficient energy use.

2. How Can I Save Money?
Set your thermostat to auto/cool. If it is set under 72, it will run all the time and increase your energy bill. If you are leaving for only a few hours, set your thermostat about 5-8 degrees higher than you usually have it. For every degree you raise your thermostat above 75 degrees you save about 5 percent on your air conditioning bill. If you turn your unit off, any potential savings may be lost when you try to bring your temperature back to where you are comfortable.

Make sure that you maintain your A/C unit. Have it serviced & inspected annually, keep filters changed regularly; once a month will help your system to run efficiently. We carry permanent and disposeable filters.  Keep  return air grilles clean & clear of any potential obstructions. A hot water heater blanket can can result in long term savings.
3. Air Conditioning Checklist

1. Disconnect electrical power at the fuse or breaker box before you begin servicing your air conditioner.

2. If you prefer, have your unit serviced by a licensed contractor. We would be happy to provide you with a no-charge referral to one of our Preferred Professional Installers.

3. If your A/C is not cooling, check the temperature setting, breaker box, and filters.
