5 Air Conditioner Ideas that Keeps Repairman Away
                     5 AIR CONDITIONER IDEAS THAT 
KEEPS REPAIRMAN AWAY
OVERVIEW
Regular maintenance is necessary for an air conditioner to work 
effectively and efficiently over its many years of service. In order to 
maintain a consistent level of air conditioning performance, it is 
important to not neglect necessary maintenance. However, energy 
consumption will continue to rise.
AIR CONDITIONER 
FILTERS
Routinely changing or cleaning your filters 
is the most important task to maintain your 
air conditioner's efficiency. Filters that are 
dirty or clogged can reduce airflow and 
reduce efficiency. Airflow can also be 
obstructed and air can flow through the 
filter, causing dirt to build up and 
contaminate the evaporator coil, reducing 
its heat-absorbing ability. You can reduce 
your air conditioner's energy use by 
replacing a dirty or clogged filter. This will 
help you to lower your energy consumption 
by between 5% and 15%.
DIRTY AC
Over the years, dirt builds up on the 
condenser and evaporator coils of an 
air conditioner. The evaporator coil will 
not become soiled quickly if it has a 
clean filter. However, dirt will 
eventually build up on the evaporator 
coil. The dirt can reduce airflow and 
insulate the coil, which will decrease its 
ability to absorb heat. This problem can 
be avoided by checking your 
evaporator coil once a year and 
cleaning it as needed.
COILS
Aluminum fins found on condenser and 
evaporator coils can be bent easily and 
block airflow. A "fincomb", a tool that can 
be used to comb the fins back to their 
original condition, is available from 
wholesalers of air conditioning.
WINDOW SEALS FOR 
ROOM AIR 
CONDITIONERS
Each cooling season, check the seal 
between your window frame and the 
window air conditioner to make sure it is 
in contact with the metal case. This seal 
can be damaged by moisture, which will 
allow cool air to escape your home.
