Frequently asked in Ontario

Why is my AC running but not cooling?

If your AC unit in Ontario is running but not cooling your home effectively, there are several common reasons. These can include low refrigerant levels, a dirty air filter, a malfunctioning fan motor, or issues with the outdoor condenser unit. Sometimes, a simple fix resolves the problem, but other times a professional diagnosis is necessary to identify the root cause.

What does a typical AC repair cost?

What is the 3-minute rule for AC?

The 3-minute rule for AC systems advises waiting at least three minutes after your unit has shut off before restarting it. This pause allows the internal refrigerant pressures to equalize, preventing unnecessary stress on the compressor. Adhering to this simple guideline can help extend the operational life of your AC unit in Ontario.
