In the spring of 2025 I needed a new HVAC company to service my air conditioner and furnace. I…read morewanted to find a company that did not advertise or a chain HVAC company. I signed a maintenance contract with Zilka in May of 2025. I'm so glad I did. Yesterday Jack installed a new whole-house humidifier that is perfect for me. In addition, I had called around for pricing the unit offered and their initial price to me could not be beat. I'm delighted with their service. A big shout out to the knowledgeable ladies that work in the service department and to Nathan in the Parts Department who helped me in this transaction. This company is the real deal when it comes to service.

My 25-year-old furnace was limping along, and it was finally time to get a new one. I knew this…read morepainful day was coming sooner than later, and I didn't have a clue where to begin. I went through the three-estimate process (highly recommend it because you learn a lot!), and I chose Detroit Heating & Cooling. This was a significant purchase for me, and they were incredibly helpful and super patient. The installation went smoothly without any scary surprises. Justin and Travis were knowledgeable and professional. Justin explained the job and also showed me how to change a humidifier filter that hadn't been replaced in 15 years--oops. They are experienced and honest, and their pricing was very fair. I always dread dealing with any kind of home repair or installation, and I felt like DH&C genuinely worked in my best interest. Highly recommend.

I gave Thornton and grooms a second chance to complete my AC inspection. They arrived as scheduled,…read moreI was the first call of the day the service man, Kyle was thorough and provided me with a step-by-step analysis of my AC. I decided to sign up for the yearly service plan, because of the quality services that I receive from Kyle. My original assessment of Thornton grooms was a one star, but I've upgraded it to a five star based on this appointment that I had today. The only thing that I could recommend for future appointments is that Thornton and grooms provide a two hour window for serviceman to come out. Otherwise, I can highly recommend this company.

Very disappointed with Thornton & Grooms Plumbing…read more My elderly parents had previously used this company to unclog their main drain for about $100. This time, the technician arrived with a smaller machine that he admitted could not do the job. Instead of being upfront, the company tried to charge them $670 to "come back the next day with a bigger machine." This felt like a bait-and-switch tactic. When I called to speak with a supervisor, I was refused and told the customer service rep could "handle it." Rather than making things right or helping my parents with their plumbing issue, the company simply canceled the job and refunded the money, leaving my parents still without a working drain. While I appreciate the refund, the lack of transparency, poor customer service, and treatment of elderly customers is concerning. I would not recommend this company.
