Check that grass, leaves, dirt etc. do not obstruct the out door coil. The coil fins may be cleaned by flushing with a water hose. Be sure to shut off power to unit before flushing to avoid electrical shock hazard. Do not flatten or bend coil fins, as this will harm unit efficiency.
The outdoor unit should be set with proper slope and graded so there is no buildup of water around unit. If there is a water drainage problem, give us a call to have the condenser re-leveled. Do not attempt to move the unit yourself as this may damage the unit’s piping connections, resulting in refrigerant leaks and an inoperative system.
Your condensing unit cabinet has been designed for minimum care. An occasional coat of wax will help to prevent deterioration of the finish and enhance its durability.
Condensation takes place on the indoor cooling coil and is piped to a suitable drain.
Check the condensate drain for free and running condition. If water does not run freely, the drainpipe must be cleaned. Some coils are equipped with an auxiliary drain (secondary drain). This drain is usually piped to an outside location where it can be observed. The auxiliary drain is a safety device to prevent overflow of condensate into the house. If water runs from the auxiliary drain, it indicates that the main condensate drain is clogged. Immediate steps should then be taken to service the main drain. Your Central City Air serviceman is properly trained to remedy this problem, and should be consulted in the event of this poor drainage condition.
Air filters should be checked monthly. A dirty filter should be replaced or cleaned immediately as it will cause your equipment to work a great deal harder than necessary, resulting in energy waste and possible internal damage.
CAUTION: Shut power off to unit before removing access panel to change filter. Wait for blower to stop.
If the filter appears dirty, change it out for a clean one.
