HVAC reviews in Dearborn Heights, Michigan

My AC went out and I called A to Z. The tech, Robert, was very professional and polite. He was very quick to troubleshoot the problem and not only fixed the problem but detected some issues I was about to have in the near future and corrected them. He also adjusted my fan motor speed and got better efficiency out of my AC. I couldn’t be happier with the how fast and professional the experience was. I tech sound systems for a living and Robert is a top notch troubleshooter. I highly recommend.

We have been customers for fifteen yrs. The staff, the service and quality are great. We are loyal fans and would not hesitate to recommend them for all your A/C and heating needs...

Robert has been our tech numerous times in the last 6 years. He is courteous knowledgable and we are grateful for his help. Thanks for aleays being there when we need it . Thanks A to Z Heating and Cooling

We went from an unsafe self installed tankless to a safe, efficient tank. Reason being is because we purchased this home with this self installed tankless hooked up, which was producing carbon monoxide and leaking. A to Z took the job, when no one else wanted too, and for a great price. I am very grateful. If you need a hot water tank installed, call them. Their prices are great and so is their work. You won’t be disappointed.

Great service Everytime. Also very friendly call staff with knowledgeable experience. Laura was very helpful and got us an appointment right away. Techs are friendly and give helpful advice. Would definitely advise a friend.

Been a customer for a while now and every experience with A to Z has been top notch. Robert was professional, pleasant and knowledgeable when answering questions. I have recommended A to Z to all my family and friends.

This is my third hot water tank from A To Z for multiple properties. They also installed a furnace for me. Great company fair pricing and awesome customer service. If you want your Hvac service done professional contact A To Z. They will get you together ❤️

I have been a customer of A to z for years now. I am enrolled in their PM service program which offers peace of mind heading into each season. Their staff is always professional and friendly from your initial phone call to the technician in your home.

Called to get carbon monoxide testing done in order to sell. Got a same day appointment and Steve also looked into another question without hesitation. Used them for the initial install as well. No issues, great communication and friendly.

Nick and Steve fixed our no heat condition in a half hour. We are extremely pleasrd with thier service and professionalism. Thanks A&Z for the great service.

A to Z total heating &cooling ; Lisa who set up everything was great. steve who came out and look over the job was great aswell. Marvin and Andrew came out ,and performed at a very high level ,down to earth and courteous and they were very helpful to me when I was asking questions about the job they were doing. I would recommend A to Z total heating and cooling to all of my neighbors and friends they get 5 ⭐️ ⭐️ ⭐️⭐️⭐️ from me.

I highly recommend A-Z. They have always done a great job for me. This is the reason I always call them for repair and maintenance needs.
Steve, my technician was very thorough, efficient and great in communicating all issues to me.

Good experience, Steve explained everything well and answered all my questions when he came out for estimate. Price was the lowest from other 3 estimates I got. Installation was good and installers answered all my questions. I would recommend to anyone looking for furnace replacement.

This weekend when I turned on my furnace, it was blowing cold air. I contacted A to Z Heating and Cooling and talked to Lisa (who was absolutely amazing) and had Chris out within 20 minutes of my call. Chris came in and assessed the situation, and is able to fix the furnace. He said that we will be his first stop in the morning! I highly recommend Lisa and Chris from A to Z Heating and Cooling!

My 17 year old furnace broke down in the middle of a below freezing week. Technicians Marv and Joe were able to quickly come out and replace the furnace. I am very happy with the new unit. The technicians were detail oriented with their work and A-Z provided a quality furnace. Thank you!

UPDATE: Months later I asked A-Z about replacing my 30 year old AC system and broken water heater. Joe came over same day to provide me with options. He was so kind and knowledgeable. Technicians David, Brian, and Chris did a beautiful job. Im very happy that my home is now fully serviced by A-Z.

Hey, they're good. They came out early was here in about an hour. Did all the maintenance was worth? It changed all the filters cleaned. Vacuumed, it cleaned up the igniter to for the furnace, and I'm very confident that my furnace is going to get me through the winter. Steve c was very nice, very professional.. o

Amazing service and super fast turnaround time. Lisa and the crew are rock stars. Steve and the other tech (I apologize for not remembering his name) were professional and kept me informed throughout the furnace install. Highly recommend.

Lisa was awesome to work with to get our home back comfortable. Chris did a fantastic job when he came out and diagnosed the problem we were having. The two techs that came to install the new furnace were so nice, and explained everything that they did. If you're having heating or cooling needs I highly recommend this company. You will not be disappointed! Thanks you all so much ❤️

Highly recommend! Robert came out to fix a quirky thermostat- he quickly assessed the problem, resolved the issue and had us back nice and toasty warm in a short time. Robert was personable, professional, efficient and effective well done!

Great efficient service. Very family oriented. Fast and friendly responses. 2nd time (house) we hired them for a complete furnace & AC systems. After DTE couldn’t fix our furnace for 10 days and 3 different techs later with no heat for 2 full weeks, AtoZ got the job done! Thank you.

I needed to get a boiler inspection done to complete my rental application. The house was vacant so I shared with them the lockbox code. I was not able to be there in person. The technician realized that one of the two thermostats was not working due to dead batteries. He then went ahead and replaced them with an emergency set he keeps in the truck and he was able to successfully complete the boiler check and approval. He could’ve easily said that the test could not be completed because the thermostat is not working and had me replace the batteries and reschedule the inspection. Instead, he did right for the customer, differentiated the company he represents and save all of us hours of headaches. Well done!
