HVAC reviews in Detroit, Michigan

We got 2 AC and 2 furnace installed. Mark and his team was very professional and finished job in time with excellent quality. Mark also accommodated our request to add gas line . We are extremely pleased with work. Highly recommend.

Servicio a medias, párese que uno les hace el favor de venir a comprar ... Les falta trato y que alguien atienda a los que hablamos español .. que solos un buen mercado ...

Great guys working there and very knowledgeable.

Not open to the public. Fine I'll give my cash money to someone else

The workers there are just miserable and they are always getting the wrong parts and that's if they even know what the parts are. No common sense. Very unfriendly

I have had an account there for over eight years. Every time that I ever went to make a purchase one particular white guy was so nasty every time that I shop there.But today February 6 was the worst before I could say hello a white guy went ham on me. He said People watch YouTube come here thinking they can fix a furnace. What right did he have to even make that comment and what do YouTube have to do with anything. I checked him.The white guy was so mad that he called to check on the HVAC license that had expired.So I take it he’s the manager or owner son because no one could put up with that behavior on any job. I called to complain to a manager and told him yes, the HVAC was expired on the account, we can get that fixed tomorrow. Can that nasty rude personality of the person at customer service be fixed, he didn’t have an answer for that.
