Salesman was friendly and personable. Did not push extras and was very easy to negotiate with. Price was right and below the competition. Installation team arrived when they said that they would, went about their business quickly and efficiently, answered any question that I had during installation and explained what they had done when finished. I have used Mr. Furnace for repair in the past and they have always been great. Installed AC, Humidifier and thermostat.

Had great experience with Mr Furnace! The split unit in my rental went out in the middle of high heat season this summer. They came out the same day to try diagnose and fix it. When he was determined that the unit need to be replaced, the owner reached out to me personally. He took the time too, walk me through the situation and answer all of my questions. And it was installed in a few days with great customer service. Would definitely recommend using them in the future.
