Stephen gave us exceptional service. He was thorough in his maintenance of the unit and in his explanation of everything he was looking at and for in terms of its health and longevity, even resetting the thermostat for us and explaining its time settings and showing me how and when to adjust the humidifier.
There is no question that Stephen loves his work and job and reflects a dedication to excellence all around.

I awoke this morning with no heat. Furnace motor was running but there was no heat. The first company I called could not come out until Monday (This is Saturday morning in MIchigan---snowy and cold), My good friend suggested I call Sun Heating and I did. I talked with the person who answered and she took my information and said a technician would call me back. Within 30 minutes I received a call back from the technician who said he would be able to come out later in the afternoon to see what the problem was. His name was Jacob. About an hour later I received a call from a different technician,

A Sun Heating technician was scheduled to arrive between 10 and 1 today. At 10am on the nose my front doorbell rang. It was the Sun service tech. I invited him in and he introduced himself. We spent a few minutes discussing my concerns and he went to work on my two zone furnaces. He was here to do general maintenance and it was the first time Sun has been my service company. Well, I am happy to report that my tech was absolutely fantastic. He was thorough. He was extremely polite. He was wonderfully trained and he found a number of issues that needed attention. When he left my home I was completely

Sun Heating and Cooling review;
I needed diagnostic test of my heating and cooling system; SH&C had great marketing (I LOVE THOSE GUYS!!) and I contacted them to do my analysis;
The guys who came over for an “inspection” of my furnaces were really nice guys; Charlie was a trainee who I wish a great future and success . His trainer; Ash; another very nice man.
The reason for service call was because one furnace did not kick on.
Upon arrival I was informed that the $89 check up was for 1 furnace and since I have two; it’s a double fee. Okay. Analysis was a blown fuse in one furnace which

Our AC had completely died about 2 weeks ago and these days we've had temps in the high 80s outside, we were anxiously waiting installation for a new unit.
Travis and Ricky came out this morning arriving promptly at 8 as we were told. They were friendly, polite, professional, no fuss just working away at getting the top part of the furnace completely replaced and the vacuum pump outside too. It was a FIVE hour job given the complex setup we had here, and they were even cognizant that I had meetings I was attending from home.
The AC has now been running for over an hour and is much more effective

I would most definitely recommend SUN Heating & Cooling Company for any HVAC issues. Started using SUN last fall, very professional and knowledgeable. I signed up for the maintenance contract, which does save you money & you get service quickly. Had Richard from SUN today, he was extremely patient with me, explaining step by step what he did (I… had a whistling sound coming through registers every time furnace turned on, was driving me nuts). I asked for his opinion on the "NEST" app where I would be able to control what I want my heat & AC on via my phone. I appreciated him

I've been with Sun Heating close to 30 years now. They have always done a great job for me and my family. When we move... they'll be coming with us to our new home. Cam was here this past week and did a wonderful job. Kind, respectful and (as always) did a great job!
