AIR CONDITIONER MAINTENANCE

 WARNING:

To prevent electrical shock, personal injury, or 

death, disconnect all electrical power to the unit 

before performing any maintenance or service. 

The unit may have more than one electrical 

supply.

Proper maintenance is important to achieve optimum 

performance from the air conditioner. The ability to properly 

perform maintenance on this equipment requires certain 

mechanical skills and tools. If you do not possess these 

skills, contact your dealer for maintenance. Consult your 

local dealer about the availability of maintenance contracts. 

Routine maintenance should include the following:

•  Inspect and clean or replace air filters at the beginning of 

each heating and cooling season, or more frequently if 

required.

•  Inspect the condensate drains in the units basepan and 

the outdoor coil at the beginning of each cooling season. 

Remove any debris. Clean the outdoor coil and louvers 

as necessary using a mild detergent and water. Rinse 

thoroughly with water.

•  To access the outdoor coil on units equipped with louvered 

panels, refer to 

Figure 2

 for panel removal and 

Figure 3

 

for panel installation.

• Inspect the electrical connections for tightness at the 

beginning of each heating and cooling season. Service 

as necessary.

•  Do not attempt to add additional oil or grease to motors 

unequipped with oil tubes or grease fittings.  Most outdoor 

unit motors are manufactured with sealed, permanently 

lubricated bearings that are designed for the life of the 

equipment without maintenance.

•  The compressor is hermetically sealed and shipped from 

the factory with the proper oil charge for most installations.  

Lubricating oil should only be added by trained personnel 

and is typically only required for long line-sets or tall riser 

applications.
