Welcome to One Hour Heating & Air Conditioning

If you have a heating or air conditioning problem... DON'T PANIC! At last. A Serviceman who is... “Always on time... or you don’t pay a dime” (no one else makes you this bold guarantee!)

That’s the promise made by One Hour Heating & Air Conditioning, the leading “on time” service company in Ontario. In fact, if our serviceman is even one minute late the repair is on us. Plus, we have convenient appointment times that fit your schedule 7 days a week.

Life is rarely convenient so, of course, you needed it fixed yesterday… We’re on it! We’ve provided prompt, reliable service since 1989. Whether you need us to fix the old one or install a new state-of-the-art high efficiency comfort system, you’ve come to the right place.
