Heat Pump & Air Conditioner

SPLIT AIR CONDITIONER OR HEAT PUMP MAINTENANCE
The heat pump for these systems must be inspected, cleaned and serviced regularly. Contact your Carrier dealer for maintenance services or tips.

THE COIL
Make sure that there is nothing obstructing your outdoor unit’s air flow, including grass, leaves, plants, or paper. To clean the coil, you may vacuum it or wash it down with a garden hose after switching off the main disconnect. Keep the fan motor and control box as dry as possible. After cleaning the coil, flush any dirt from the base pan.

Caution: You should contact your Carrier dealer to have your coil installed, serviced, or replaced.

FAN MOTORS
Normally, your motor should not need oiling for years. If it does, check your unit for motor lubrication ports first. Use 10-15 drops or ¼ tsp of SAE 20 non-detergent electric motor oil or automobile oil ONLY to lubricate each bearing. If you have an add-on type system, you should do the same for the furnace blower motor.

FILTERS
Filters should be checked each month for optimum efficiency. Dirty reusable filters should be washed with a mild detergent or replaced altogether. When installing a new filter, the airflow arrow should match the direction of your duct’s air flow.
