Lennox International Inc. 11 - Manual (Page 4)

Nobody knows more about the care and operation of
your new Lennox equipment than your independent
Lennox dealer. This means that your independent
Lennox dealer is your best choice for routine
maintenance or service. Lennox’ Quality Dealer
Standards program ensures that when you call your
independent Lennox dealer, you can count on
prompt, courteous and professional service.
Before the start of each cooling season, the following
air conditioning service checks should be performed
by a qualified service technician. As always,
electrical power to the unit must be turned off
prior to any unit maintenance.
● The outdoor condenser coil and indoor evaporator
coil should be inspected and cleaned. The outdoor
condenser coil may be flushed with a water hose.
● The refrigerant lines should be visually inspected
and the coils should be checked for leaks.
● Wiring should be checked for loose connections.
● Voltage must be checked at the indoor and
outdoor units (units operating).
● The amp-draw at the condenser fan motor and
indoor blower motor should be checked. Values
should be compared with those given on unit

● Indoor unit filters should be cleaned or replaced.
● The refrigerant charge should be checked and
system pressures should be gauged.
● The condensate drain line should be checked for
free and unobstructed flow and it should be
