+ -1 moreDennis is extremely knowledgeable and has always explained what's wrong in a way that I can easily understand. He is very easy to talk to and is one of the most trustworthy individuals we have worked with in the past.
Description of Work: We moved into a new home that had a furnance on its last leg. Dennis has bent over backwards to help us with our furnance issues, from maintenance, circuit boards to the fan motor.
