There are a few things that most homeowners can do themselves to help maintain their air conditioner:
- Ensure the filter is clean or replaced regularly. Disposable filters are inexpensive and should be replaced once per month during high use periods.
- Trim back plants so there is at least one foot of clearance from the A/C unit – this allows proper air flow, reducing motor strain.
- Sand and other debris can get sucked into the condenser coils. To clean the coils, first disconnect the power to the A/C and then use a garden hose to spray the coils clean.
Even if you do these things, you should have an annual maintenance service performed by a professional air conditioning technician. Always ensure the following items are included in the maintenance service:
- Condenser – check pressure, oil motor bearings, and current electrical draw; tighten all hardware and visually inspect wiring and condenser coils.
- Air Handler/Evaporator – Visually inspect wiring and oil motor bearings; clean or replace filter, tighten all hardware, inspect condensation drain, pan, pump, and auxiliary pan; clean drain system, and check that evaporator coils are clean and free of damage.
With proper maintenance, the air conditioner should run smoothly for years.
