Homeowner’s Information

Important System Information

  •   Your system should never be operated without a 

clean air filter properly installed.

  •   Return air and supply air registers should be free 

from restrictions or obstructions to allow full flow of 

air.

Regular Maintenance Requirements

  Your system should be regularly inspected by a  

qualifed service technician. These regular visits may 

include (among other things) checks for:

  •  Motor operation

  •  Ductwork air leaks

  •  Coil & drainpan cleanliness (indoor and outdoor)

  •  Electrical component operation & wiring check

  •  Proper refrigerant level & refrigerant leaks

  •  Proper airflow

  •  Drainage of condensate

  •  Air filters(s) performance

  •  Blower wheel alignment, balance & cleaning

  •  Primary & secondary drain line cleanliness

  •  Proper defrost operation (heat pumps)

  There is some routine maintenance procedures you 

can do to help keep your system operating at peak  

performance between visits.

Air Filter

  Inspect air filters at least monthly and replace or clean 

as required. Disposable filters should be replaced. 

 

Washable filters may be cleaned by soaking in mild 

 

detergent and rinsing with cold water. Replace filters with 

the arrows pointing in the direction of airflow. Dirty filters 

are the most common cause of poor heating/cooling  

performance and compressor failures.

Indoor Coil

  If the sytem has been operated with a clean filter in 

place, it should require minimal cleaning. Use a vacuum 

cleaner and soft brush attachment to remove any  

accumulation of dust from the top and underside of the 

finned coil surface. However, perform this maintenance 

only when the coil is completely dry.

  If the coil cannot be cleaned by this method, call your 

dealer for service. It may need a detergent solution and 

rinsing with water for cleaning, which may require coil 

removal, You should not attempt this yourself.

Condensate Drain

  During cooling season check at least monthly for free 

flow of drainage and clean if necessary.

Condenser Coils

  Grass cuttings, leaves, dirt, dust, lint from clothes dry-

ers, and fall off trees can be drawn into coils by  

movement of the air. Clogged condenser coils will lower 

the efficiency of your unit and cause damage to the 

 

condenser.

Periodically, debris should be brushed from the  

condenser coils.

SHARP OBJECT HAZARD!

  WARNING

Condenser coils have sharp edges. Wear adequate 

body protection on body extremities (e.g. gloves) .

FAILURE TO FOLLOW THIS WARNING COULD  

RESULT IN BODILY INJURY.

  Use a soft brush with light pressure only. DO NOT 

damage or bend condenser coil fins. Damaged or bent 

fins may affect unit operation.

Painted Surfaces

  For maximum protection of the unit’s finish, a good 

grade of automobile wax should be applied every year. In 

geographical areas where water has a high concentration 

of minerals (calcium, iron, sulfur, etc.) , it is recommended 

that lawn sprinklers not be allowed to spray the unit. In 

such applications, the sprinklers should be directed away 

from the unit. Failure to follow this precaution may result 

in premature deterioration of the unit finish and metal 

components.

  In sea coast areas, special maintenance is required 

due to the corrosive atmosphere provided by the high salt 

concentration in ocean mists and the air. Periodic  

washing of all exposed surfaces and coil will add  

additional life to your unit. Please consult your installing 

dealer for proper procedures in your geographic area.

IF YOUR SYSTEM DOES NOT WORK,  

BEFORE REQUESTING A SERVICE CALL:

1.  Ensure thermostat is set below (cooling) or above 

(heating) room temperature and that the system lever 

is in the “COOL”, “HEAT” or “AUTO” position.

2.  Inspect your return air filter: If it is dirty your air condi

-

tioner may not fuction properly.

3.  Check indoor and outdoor disconnect switches.  

Confirm circuit breakers are ON or that fuses have not 

blown. Reset breakers/replace fuses as necessary.

4.  Inspect the outdoor unit for clogged condenser 

coils,(grass cuttings, leaves, dirt, dust or lint). Ensure 

that branches, twigs or other debris are not obstructing 

the condenser fan.

IF YOUR SYSTEM STILL DOES NOT OPERATE, CON-

TACT YOUR SERVICING DEALER.

  Be sure to describe the problem, and have the model 

and serial numbers of the equipment available.

  If warranted replacement parts are required, the war-

ranty must be processed through a qualified distribution 

 

location.
