It’s summer time.  The AC has been working overtime and the freezer has been churning out ice cubes for those tall glasses of lemonade.  In our efforts to stay cool it is important to keep our cooling equipment from overheating, you can prevent this from happening by keeping the following tips in mind: 

  1. Checking the filter monthly (and changing it when it is dirty or when the manufacturer recommends) in your central air conditioning (furnace) is the easiest thing to do to keep your AC working efficiently.  The filter prevents dust and particles from damaging the coil in your HVAC equipment and helps clean the air as it circulates through the house. The filter is the first line of defense to stop indoor air pollution.  When the filter gets dirty less air flows through the coil and it takes longer to cool the house.  Change dirty filters promptly.  A clogged, dirty filter can reduce the efficiency of your air conditioning unit by as much as 15%.  It is always a good idea to have a few spare filters on hand.


Just a couple of weeks ago I was visiting a group home whose AC had not been working for two days.  I opened it up and as you can see,  it was definitely time to change the filter.

  1. The condensing unit of the AC system (the metal box outside the exterior wall) should also be cleaned regularly during the summer.  The condenser draws air up through the coil and disperses the heat outside.  A dirty coil prevents the heat from dispersing and makes it more difficult to cool the house.  Leaves, fuzz, and debris can get stuck in the coil reducing the effectiveness of the system.  A soft broom, or spray from the garden hose can be used to clean the coil.  Be careful as you do not want to bend the aluminum fins on the coil.


  1. Your fridge is also like an air conditioning system.  It removes heat from inside the fridge and sends it into the room.  Most fridges have a condensing coil on the bottom, behind the removable kick plate, under the door. Cleaning this coil will also increase the efficiency of your fridge as you can imagine a large amount of dust can get drawn up through the coil.  Remove the kick plate clean the coil with the soft brush attachment on your vacuum cleaner.  A flash light may be needed to see exactly where all the dust is hiding.  You will be amazed at how much dust has collected under your fridge, and how much faster a clean fridge can make ice cubes.   Try doing this twice a year.


  1. Replacing or cleaning filters in all types of equipment is important and a good first step in planning maintenance to save money.  The range hood, and dryer are good places to start looking for dirty filters.  Your dryer will run more efficiently too with a clean lint filter.  Take time to go outside and clean the inside of the dryer vent as well.


  1. While you are outside walk completely around your building and look for any damage that may have been caused by severe weather.  Look for missing pieces of shingles, metal trim that is bent or eaves troughs that have come away from the building.  Wind can tear off shingles and rip flashing off the roof, and hail can put holes in vinyl siding and damage the shingles.  Torn shingles left unattended on your roof can soon develop leaks.  It is easier to replace a few torn shingles than replace wet drywall on the ceiling.   If you find you have damage caused by severe weather call your insurance company.


By following these tips you will be sure to have the rest of your summer to relax and enjoy the sunshine – and that refreshing blast of AC.
