Toronto summers are humid, and a broken air conditioner turns a home uncomfortable in hours. Our technicians diagnose and repair central air conditioners, ductless mini-splits and air handlers, with fully stocked vans so we can often fix the problem the same day you call.
Common AC failures include bad capacitors, failed contactors, frozen evaporator coils, clogged condensate drains and refrigerant leaks. We find the cause, not just the symptom: if your system is low on refrigerant, we look for the leak instead of simply topping it up and sending you a bill again next month.
