I also love their text feature where they send you a picture of the technician coming to your house and call you to let you know when they're on their way. Wonderful customer service!! Kevin was the technician who serviced my hot water heater and went above and beyond to help me. He was friendly and thorough with his work and also explained the diagnostics in simpler terms (for people like me who know nothing about this stuff LOL). He even helped me clean my filter that was dirty and left me some extra tape. I highly recommend this company and will use them again for any HVAC needs!

This is not to be confused with Comfort ZONE, which is also in Royal Oak - this is Comfort ZONES…read moreHeating & Air Conditioning. I made a Yelp page for them since the other business already has an established Yelp page. Last Tuesday, I noticed my hot water heater making odd noises, after I took a bath that night. I went to look and sure enough, there was about a half-inch of water on the floor. Last year I experienced a massive house flood, so I definitely didn't want that to happen again. I have an Appliance Plan with Consumers Energy so I called them, and they outsourced it to Comfort Zone. Comfort Zone showed up at my house the next morning, diagnosed the problem (water landing on top of the flame, apparently), and were able to install a new water heater the same day, which was great. The cost was $1470, which sounds like a lot but Lowe's was quoting me $1650+ that same day, too. The reason for the three stars is that they aren't great at answering the phone. The next day after the water heater installation, one of my sinks was operating at about 60-70% of its former water stream, so they said they'd send someone down to look at it (this was Thursday). By 4-5pm Thursday I hadn't heard back from them and no one had shown up, I left them a voicemail to say Friday would be fine. I called again Friday morning and got voicemail again; I said that 3:30pm would be the latest I could have someone over on Friday. Sure enough, at like 3:25pm one of the techs, Cory, did show up, and was able to fix the problem ... but there was no communication from either him or Denise, the receptionist (and possibly owner?), about this. That being said, I'd still use them again because they were able to quickly diagnose the problem + install a new water heater on the same day, so I didn't have to stay somewhere else overnight, since I had to turn off the water to my entire house.

He installed the heater and again the permit inspector told us that he did excellent work, and that in most cases corrections have to be made and he has to come out a second time.

Edit: We just had them back out to install a new ductless mini-split system to cool our home and their work was, yet again, top notch!
