Considering we’re still using our warm blankets in bed at night, it might not seem the time to think about that air conditioner.
But Metro Vancouver weather is unpredictable and summer could arrive soon (sound of fingers crossing)!
Your air conditioning unit has been lying dormant since last fall, so it’s time for some maintenance to ensure it’s ready and raring to go when the temperature heats up.
No matter how big or small a unit you have, or if it’s indoor or outdoor, it needs to be professionally inspected in late spring. A Lewis MacLean 24-hour Residential Air Conditioning Professional will ensure your AC hums along smoothly all summer. However, there are some things a homeowner can watch for as well. These are some of the items that need to be addressed by you or your Lewis MacLean Professional.

Inspect the unit for the correct level of refrigerant
Clean out all the yucky dirt, leaves and debris that have accumulated
Inspect the base pan for drain openings that have become clogged
Inspect coil and cabinet
Inspect the fan motor and fan blades for wear and tear
Inspect the control box, wiring and connections. Controls may include contactors, relays, circuit boards, capacitors, sump heat and other accessories. All control box and electrical parts should be checked for wear or damage.
Inspect compressor and associated tubing for damage

Inspect and clean blower assembly
On older models, a little more TLC is needed, such as lubricating the motor and replacing the fan belt
Inspect evaporator coil, drain pan and condensate drain lines.
Inspect control box, associated controls, wiring and connections
Clean or replace the air filters
Inspect conditioned airflow system (ductwork)—check for leaks

Listen for abnormal noise
Search for sources of unusual odours
Measure temperature rise and adjust airflow as needed
