Beat the Heat: Air Conditioner Maintenance Tips to Kick Off the Summer Right
June 3rd, 2025
As days lengthen and temperatures rise, restarting your air conditioner without proper
care can lead to breakdowns, overconsumption, and discomfort. A preseason tune-up
ensures optimal performance, extended lifespan, and energy savings. Follow these key
steps before you switch on the cool air.
1. Shut off the power
Before any work, turn off the breaker for both the indoor and outdoor units. This simple
precaution prevents short circuits and electrical hazards.
2. Clean or replace the filters
Filters trap dust, hair, and pollen. A clogged filter reduces airflow, overloads the
compressor, and encourages mold. Remove them, wash under warm water with mild
soap, let them dry completely, or replace if they look worn.
3. Inspect the evaporator and condenser coils
Both sets of coils must be free of dust and debris. Use a soft brush or an HVAC-specific
cleaning spray to dislodge impurities. Optimized heat exchange lowers consumption and
improves comfort.
4. Clear the area around the outdoor unit
Ensure branches, tall grass, and debris do not obstruct airflow. Maintain at least 50 cm
clearance on all sides and keep pruning shears handy to trim vegetation quickly.
5. Check refrigerant pressure
A leak or low refrigerant level reduces cooling efficiency. If your unit struggles to cool or
frost appears on the coils, have a certified technician verify and refill as needed.
6. Flush the condensate pan
Condensation normally drains through a pipe. Confirm it isn’t blocked and clean the
collection pan to prevent overflow or bacterial growth.
7. Reprogram your thermostat
If you have a programmable thermostat, set it to kick in before peak hours—early
morning or evening. This gradual cooling approach maximizes comfort and controls your
energy bill.
By rigorously applying these tips, your air conditioner will be ready to face summer
without surprises. For a full, professional service, Frigotech Outaouais offers tailored
