Tips for End of Summer Air Conditioning Savings

As we approach the end of summer, it’s a good idea to give your air conditioning system some service, as it’s been humming along for a few months and may need attention.  

Most of these tips are things you can do to make your system more efficient and protect it from unnecessary wear and tear.

  • Check the air filter for the blower. When the filter collects too much dust and airborne particles, it slows the passage of air through the blower. This makes cooling your home more difficult and it raises your energy bills. Eventually, the dust can collect on the air conditioner’s evaporator coil, which may cause it to freeze over and waste energy. When the frost melts, it may cause water damage should it flood the drain pan.
  • Inspect the condition of the outdoor condenser. Bent or dirty fins slow the cooling process. The refrigerant passes through a coil inside the condenser and the fins help dissipate the heat, much like your vehicle’s radiator does. If a summer’s worth of grass clippings have collected on the fins, it’ll take longer for the heat from your home to cool. Hosing off the fins and coil for the air conditioning compressor restores its efficiency.
  • Remove any vegetation that’s collected near the condenser. You should have two feet of clear space on all sides of the condenser for the best ventilation. Be sure that the top of the condenser has at least five feet of unobstructed space above it. The fan inside the condenser brings air through the fins and coils, and anything that slows the process increases your electric bills.

Have your air conditioning system maintained by an HVAC professional if you haven’t already. When the technicians service your system, they go through your entire system, cleaning and adjusting the components, bringing it as closely back to factory standards as possible.

    They don’t have to be done at the same time. You can have your furnace checked in January or February and the A/C unit inspected in July or August when it is in use. All the suggestions here are easy things that you can do yourself.
    I was once told to cover only the to of the unit [a piece of plywood and a brick], as opposed to wrapping the whole unit. This is supposed to prevent damage from condensation. Any comments?

    It is also recommended you switch off the fuse for the air conditioner as it will continue to draw power over the winter even though you are not using the unit. All ac units should have a dedicated fuse.

    You say that the air conditoner should be maintained at the end of the summer.. Isn’t it funny that two days ago I got a phone call from Reliance about my hot water tank & i mentioned that I thought the furnace filter should be changed & the Air conditioner should be looked at. The reply was that I had a maintance check done in February & I was only entitled to one a year… I don’t believe in February anyone put he air on to check it.
