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.
