Our 20 year old furnace died one night and since the clear Homestars.com choice is Heating Plus, we called them in. Paul came the next day, identified the problem and we decided to replace rather than fix. The price quoted was very competitive and came with a 10 year parts and labour warranty. The guys who came to do the replacement were very professional (and although they were late, Paul's wife was kind enough to call ahead and let us know, so there was little aggravation on our part). All in all, the furnace works great and we're very satisfied with the work and value for money.

Since this review was posted, we've experienced some serious problems with our furnace, namely that it stopped working altogether. We had a professional HVAC contractor look at our furnace and he told us it was amateurishly installed. We also found out to our utter stuptefaction that our thermostat was set up for a single stage furnace, meaning that all of that energy savings from our double stage furnace were never realized. Then we checked the Better Business Bureau - they get an "F" grade (the lowest possible) and were suspended as members. STAY AWAY
