    Then David gave me a very straightforward quote on what I would call an unusual instillation request at an extremely reasonable price.

    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.

    I have 100+ year old home so my heating system is a boiler that generates steam through the…read moreradiators. Over the years, it has been difficult to find contractors that work on boilers, and it was during Covid that I got a recommendation for Koz heating when I asked who works on boilers. I would almost have to say that they specialize in boilers because the first time I had a repair the gentleman was so knowledgeable about everything going on with my boiler which was from the 1970s. This past Sunday I started having a leak in the basement so when I called the phone number they asked if I wanted an emergency call on Sunday or wanted to wait until Monday but I was concerned so he came out on Sunday and was able to tell right away that the boiler was shot. He said he would have to schedule it as soon as possible after he was able to order a boiler and he told me to plan on them working on it from eight in the morning until six at night. They showed up with three trucks and six guys the following Thursday and they were actually there from about 8:45 AM until 9:15 PM and it looks perfect and it works perfect. Thank you to Koz Heating and all of the wonderful guys who put in a great new quiet and energy efficient boiler!!!

    We bought our late 90s built home in 2012, and it only had a standard (at the time) 6-inches of…read morepink BATT insulation in the attic. So, our furnace has been working harder and more frequently to keep the house adequately heated for the past several winters. We finally got fed up of this lack of additional barrier between us and the cold outside. I was inspired by Consumers Energy offering a rebate check when insulation is upgraded by an approved vendor. I found AEE as the only Gold-star rated, licensed and insured installer in my area and approved by Consumers Energy. They earned their stars and stripes. I set up a free quote with the straight to the point and knowledgeable company owner, John. He explained his recommendations for adding about 11-12in.of fiberglass/wool blend blow-in insulation into the entire attic for a total of 17-18in., as well as having his field manager and caulk expert Mark seal all our windows and doors. He left me with a competitive quote and let me take long as I wanted to think on it and get other quotes. After a few quotes - my gut instinct gravitated me to AEE. I wanted to 'Art of the Deal' a bit with John to bring his quote closer to another competitor's. He was fair in working with me. We struck a deal. His 2-man insulation team came to our home around 10am and worked until about 4-5pm thoroughly insulating my attic. His field manager and caulking expert Mark did a great job sealing all the windows and doors for air leaks in a matter of 1-2 hours tops. They went above and beyond my expectations and were honest fellows. At one point when they realized they slightly undershot the amount of product needed for the job - they went and got more product to complete the job. John was a man of his word - he honored the contract without trying to work in the marginal unforeseen product and labor. They were thoughtful enough to blow some extra insulation into the space above our toddler's bedroom - which is definitely the problem area with our climate control. The workers used slip covers on their shoes and used towels to keep hoses from damaging walls. They vacuumed and cleared all waste after their work. Fast forward a week, and I will tell you that this was one of the best upgrades we have done for our home. The disparity in climate and cold drafts in different areas of our home is way better now. Upstairs is improved, the den stays toastier now, and the kitchen side of our house now holds heat better. A marked difference in the radiant heat comfort throughout the house. It is no placebo effect. The furnace is able to drive the temp up quicker, then the temp holds better and drops slower. So the furnace does not have to stay on as long of duration, and the interim between it firing up has increased. Savings on gas, and less wear and tear on the furnace too! Wish I had done this back when we bought the home. Better late than never. Highly recommend AEE. Just follow the simple steps I detailed above, get the work done, and get that rebate. You will have a top notch upgrade, at a great bottom line price. Two thumbs up!

    AEE engineers came to my house and identified areas of improvement that I frankly would never think…read moreare a problem. I had an extensive energy audit performed, indoor air quality check, insulation installed, window caulking, rim joist seal/insulation, thermometer replacement, and various other home improvements. This was after the cost vs. benefit was explained to me with the supporting data. Once everything was completed, they walked me through the utility company rebate and tax credit process to ensure I received the full benefit of all work performed. Ultimately, I made money from the inspection and walked away with a house that was significantly more energy efficient with lower utility bills. It's a shame that it's so rare to find great companies with great people nowadays. AEE (John and Mark in particular) were super professional, friendly, polite, and extremely knowledgeable. It was an absolute pleasure working with them and I was able to learn quite a bit. These guys are not your typical salesmen, they are subject matter experts and come with only the highest of recommendation from me!

The unit has never run smoothly; literally ever. In 2023, the unit required a whole new coil. Fast forward to 2025 and yet another new coil needed. I was told I would be called on Monday with a quote (technician came out on a Friday). It's now been a week with no call (mind you this also happened in 2023 as well; was told I'd be contacted and never was until I called). To add, the technician who came out was extremely rude. He placed the full blame for the new issue on my dog (for peeing on the unit) and told me I could not use my warranty because of it. Which I'm not saying he never has, HOWEVER, pretty sure multiple animals go through yards and an AC technician is not a fricken expert on the "smell" of dog pee. On top of that, had two other companies come out for quotes and discovered two errors made on the original install; one of which is ILLEGAL. Better yet, was told by both companies, the original issue with the AC unit could have certainly been due to a faulty install....which now makes sense given the multiple errors discovered with the original installation. Save your money and your sanity and take your business elsewhere. This company is simply out to scam you of your money. Unqualified, unprofessional.
