Culzac Heating & Air Conditioning

Great A/C service, same day service (within 5 hours of calling), on a hot day too - they must have been busy. Fixed the unit quickly for a reasonable price. We also got the same company to replace our furnace a few years ago, and it was the same experience - prompt, efficient & reasonably priced.

Excellent work, was impressed!!!
Culzac Heating and Airconditioning was provided the best service you can ask. Professional, affordable, great costume service! Definitely recommend to friends and family.

Dwayne installed a new furnace and water heater for us years ago. Recently our A/C needed a repair. I emailed him one evening, and by 10:30a the next morning it was fixed, at a fair price. Super impressive!

My wife & I used Dwayne to replace our A/C unit way back in 2010. The unit that he & his asst. Gary installed then has worked flawlessly since. We wouldn't hesitate to recommend him & his company. Thanks Dwayne!

I don't usually bother leaving reviews unless someone impresses me - which is very hard to do. Dwayne has been my go to HVAC guy for years and did not disappoint a single time. Very competitive prices, prompt responses, punctual, great to deal with and does very clean installs.

Beside some service calls in the past he just recently replaced both my furnace and water heater and I cannot be happier with the install.

We moved into our house 5 years ago and since then Dwayne has been our go to guy for our annual boiler and AC units maintenance. He is dependable and always takes the extra time to explain things to us and consult on extending the life of our units. When the time comes to replace our boiler, we will definitely be reaching out to Dwayne for his support.

Dwayne is the GOLD standard in HVAC in Toronto. He has serviced my old AC unit in the past to give it more life until we could replace it to a more efficient one. He is very responsive and arrives when he says he will. He installed a great new York unit in a tight spot on my zero lot line. I had a small issue with the new unit (not related to Dwayne's install, but a manufacture defect) and it was resolved promptly. I've had him install a furnace at my mother's house and he and his crew did a fantastic job. I wouldn't hesitate to recommend him. I wish all contractors had this level of professionalism.

I had Dwayne service my home a few years back and was extremely impressed with his work. I had him come out today to service my AC system and furnace which was leaking in the basement. Folks, you will not get better service from anyone but Dwayne Culzac. This guy is the real deal who goes beyond what he has to do to satisfy his customers. You just don't get honest service like this anymore these days. It is indeed refreshing to see this type of integrity and attention to detail in all aspects of his work. You will not be disappointed.

I can't overstate how impressed I was with Dwayne. He came highly recommended to me by my new contractors. My old contractors had damaged my old York furnace (losing the two front panels) during the renovation and I didn't like their HVAC guy (he seemed lazy and and always in a hurry to leave). Dwayne got me a good price on the panels (I was quoted 50% more by the HVAC company that supplied my furnace), then came out and diagnosed the problem in the board (a few pins got bent or broken all together). He then fixed some weird wiring the old guy did, and tagged the furnace after checking the gas lines.

I then had him look at my second furnace in my basement apartment that the old guy installed, because it smelled like gas in the furnace room. Dwayne did a bubble test and sure enough the old guy had left me with a leaking pipe. Turned out it just needed a couple of more turns to seal properly (but like I said, the old guy was lazy). He then double checked the rest of that guy's work and it happened to be okay. I'm so glad I found Dwayne & Culzac's as he knows what he's doing and honest about what's going down.

Dwayne sends regular emails about maintenance that I use to keep my furnace and AC in top shape. He is thorough and reliable (always on time and does a great job). In the summer, he replaced a vent that had developed a leak and replaced parts to make my AC quieter. When one part later failed, he promptly replaced it without charge. Great and dependable guy!
