Spring Air Conditioner Maintenance Checklist for Toronto Homes

Get your AC ready for a humid Toronto summer. Homeowner checklist plus what a professional tune-up covers.

Why spring maintenance matters

The first heat wave of the year is when we receive the most AC repair calls. Many of those breakdowns — failed capacitors, clogged drains, dirty coils — could have been caught weeks earlier. A spring tune-up costs far less than an emergency repair and keeps your system running efficiently all summer.

What homeowners can do

Replace your furnace filter, since your AC uses the same blower and ducts. Clear leaves, grass clippings and debris at least two feet around the outdoor unit. Gently rinse the outdoor coil with a garden hose from the inside out, with the power off at the disconnect. Make sure supply and return vents inside aren't blocked by furniture or rugs.

Check the condensate drain near your furnace. If you see standing water or a slow drain, it may need cleaning before it overflows.

What a professional tune-up covers

Our AC tune-up includes checking refrigerant pressures, testing capacitors and contactors, cleaning the condenser coil, inspecting the evaporator coil, flushing the condensate line, measuring temperature split and airflow, tightening electrical connections and calibrating the thermostat. We'll give you a written report and let you know about anything that needs attention.

Signs your AC needs repair, not just maintenance

Warm air from the vents, ice on the lines, a humming outdoor unit with no fan, or water around the furnace all point to a repair. Turn the system off and call us — running it can make the problem worse.
