Nine steps for preparing your air conditioning system for an Ottawa winter.
Maintenance tasks
Clean or replace the air filter. This maintains efficiency and improves indoor air quality through the heating season too.
Clean the outdoor unit. Use a garden hose to remove accumulated debris and trim nearby vegetation.
Protection measures
Cover the unit. Once cleaned, cover with a breathable, waterproof cover to shield against snow, ice, and wind.
Inspect refrigerant line insulation. Damaged sections should be replaced to prevent freezing and maintain optimal performance when spring arrives.
System preparation
Turn off the power. Switch off the outdoor unit at the breaker to prevent accidental activation and electrical issues from moisture.
Schedule a professional inspection. Catching issues now is cheaper than discovering them when you turn the system back on in May. See our AC maintenance service.
Home improvements
Check for air leaks. Around windows and doors. Easy wins for winter comfort.
Have ducts cleaned. Healthy ducts mean efficient heating too.
Install a programmable thermostat. Year-round energy savings.
