Well, regrettably, we are coming up on that time of year when we begin to remove window air conditioners. Throughout my career, I have installed and removed hundreds of window air conditioners. Yet, I can only recall a handful of times when a homeowner has asked me to inspect the window and surrounding area for any collateral damage that may have been caused by the usage of the window air conditioner.
While window air conditioners provide us with comfort and
seem to be relatively maintenance free, the reality is that you need to check
for wear and tear of the unit and surrounding area of your house with each
removal.
As for the air conditioner, you want to check the filter
and insure it is clean. Also check to make sure there is no built up water in
the unit. If you have built up water, check the braces to insure the air
condition is angled the proper way. Water should not back up in your unit or
window if the unit is pitched properly. Clean the entire exterior of your unit
before storing away, as this will help prevent discoloration and rusting. Also,
check the power cord for any cracks or breaks in the outside wrapping. Check
the sliding accordion sides for cracks and tears.
Once the unit has been inspected and repaired, it is time
to inspect the window and surrounding area for wear and substantial damage.
Check window sill and trim for wetness and/or cracking
and peeling of paint. Use an awl to probe for soft areas if you notice a
severely wet area in the wood. If you have an older home, check the cords
attached to the window weights for dry rot.
Inspect your wall directly under the window where air
conditioner has been used. Often times when water runs back towards the wind,
it finds its way down into your walls. You will also want to check exterior
wall for wetness too. Finally, check directly under window to make sure your
air conditioner has not been dripping all summer onto something below that can
be damaged by water constantly running over it.
