The best time to service your air conditioner is before
you actually need it.
Regular maintenance and cleaning are extremely important.
Change your filter monthly. Other than the regular
filter, there are additional ones you can use, but you
need to check with your air-conditioning maintenance
You can get a cap from your hardware store to put
on the end of your air-conditioning drain (figure A).
After capping it, you can find the end of the drain outside
and you can use a dry vacuum to suck out the dirt. Be
sure to remove the cap once you have vacuumed.
An air-conditioning technician needs to use a high
pressure vacuum to clear the drain. It should be done
yearly to avoid any backup that could cause mold growth
in your air conditioner and water damage to ceilings
To clean the air-conditioner coils, make sure the
power from your unit is disconnected first! Then wet
the area you are cleaning with the garden hose. Using
gloves and safety glasses spray the commercial air-conditioner
cleaner (available at an HVAC supplier) onto the coils
(figure B). Let is set for a short while and then rinse
it down thoroughly with your garden hose.
