We have been working with Rod for about a year now and he is our go-to. He works diligently and is extremely knowledgeable about what he is doing. He worked on numerous projects for us and we have been nothing short of extremely satisfied. Our house had a couple of faulty installations when it was being built — namely in HVAC, and we got to know about Ontario HVAC, and since then, Rod has fixed everything efficiently. 10/10 recommend!!
