Always have been very happy with the quick service, the service people are neat, friendly and helpful. I give them a five star rating. Thank you, joanne Jones

Joe was great, showed up on time and had everything working within an hour. Also gave me good information about my options. Thanks

Troy does an excellent job. He is very courteous and professional.

I just had a humidifier and chimney liner installed in my home. The entire experience with KOTZ was easy, and done properly. Josh came out to inspect what I wanted done, and was helpful and professional. Mark and Dave showed up to do the job on time. They were easy to get along with and did a great job. No hidden fees, great experience, cool people. Highly recommended!

I trust Kotz Heathing & Air Conditioning. Joe came out to handle a leak promptly and stood behind their work with a good attitude. He assured me everything was checked over thoroughly and explained where the problem occurred. When employee's speak highly of their employer, it tells me a lot. Lake Orion

Tom hooked up a new water conditioning system and a rust removal in my home and made me feel comfortable with the system. He worked diligently and completed it quickly. Thanks Tom.

Service tech Troy did a great job once again,answered all of our questions and even scheduled an air duct cleaning for us. Could not ask for more.

Mark was very professional and helpful with the installation of our air conditioner. I would pick Mark to do all of our installs and repairs.

Had Matt out for the second time this year, once for AC once for the furnace. Did a great job for our annual checkup. Very professional and friendly. Highly recommended! Thanks Matt!

Michael was on time and very helpful and friendly. Will have to call back as the quick solution didn't work but it was worth a try.

I have used Kotz over the years for both heating and cooling needs and believe in their knowledge of equipment and repair with highly trained technicians like Troy. I believe they are trust worthy and will only due what is necessary and not charge you for anything you do not need. KS.

Troy (and John) arrived after calling first to let me know he was coming. Troy talked to me about adding the cleaning of the electronic filters, which he did and then walked me through the results of their work. Just what I wanted, competent work with minimum hassle.

Joe was on time and very professional. Work was completed on 1st visit. Will request Joe next time I need service. Very Happy with service experience.

I have used Kotz for several years and have been completely satisfied. Troy was just here today for our annual air conditioning maintenance. Troy was very professional, punctual, and informative.

Just a pleasure to do business with. I called today 6/22/15 at 9:00 AM for an A/C problem and I had Michael at my door at 10:45 AM, Very professional, didn't try to sell me anything, didn't use scare tactics to replace this or that, just came in did the work and did it correctly, and then stayed around to make sure it was doing what it was supposed to do. These guys have my business from now on. Totally satisfied with the company and Michael (Thank you for the rapid response and concern)
