Kotz Heating & Air Conditioning

Founded 1987 • With Angi since February 2008

Kotz Heating, Cooling and Plumbing is a customer focused heating and air-conditioning company that was originally started in 1987. Located in Waterford, MI, we employ highly trained people whose goal is to make our company the best service company in Oakland County Michigan. Our company specializes in designing, engineering, and installing complete comfort systems for owners of existing homes and buildings just like yours. We take special pride in the craftsmen we train and employ--a fact you'll notice immediately in the attitude and integrity they bring to your job site. Our entire company works hard to make your experience with us hassle-free and enjoyable. Should we make a mistake, we will do everything in our power to correct it to your satisfaction. From the professionalism of our sales engineers, to the dedication of our field personnel, we are dedicated to delivering you the best. We take our responsibility very seriously when you place your trust in us. We pledge to always tell you up front what your cost will be to complete your job correctly. We make it a point to go over any details or limitations of the proposed system that will affect your enjoyment of the end result. You are told exactly what to expect up front. We back this philosophy with our exclusive written guarantee when choosing Kotz Heating, Cooling and Plumbing to contract your job: “If at any time during the first year of installation, you are not 100% satisfied with the performance of the equipment, our service or even our people, we will, within 30 days of your request, remove the system and cheerfully refund the entire amount of the contract.” Compare our guarantee with the limitations, fine print and exclusions other companies tend to use to back their work today. Others will typically guarantee only the functionality of the equipment--not your satisfaction with the process or that the finished job lives up to your expectations.

Beware! This company quoted me an AC/Heating system but did not include vital parts of the system that I had directly spoken to the salesperson about. When the parts died (6 months later), they stated that they didn't replace the items because they were working when they installed the new system. When they came to install the parts, which I was going to pay for, the maintenance man discovered that when they installed the furnace, they apparently never installed a humidifier pad, so it leaked all over my Furnace room and grew mold. When they were trying to install the parts, dry the water under the heater, and fix the humidifier pad, they broke my instant-on hot water heater. When confronted, they said they couldn't fix it, the maintenance man drove away - leaving my garage open, which caused further damage, and when I called, they told me they 'fired me as a customer'???? I have bought two full systems from this company and referred them to three other people who also installed entire new systems. This is shocking business behavior by any standards.

I was not having any issues with my current system but wanted to update the system (~18 years old and low efficiency). Kotz did an excellent job of inspecting my current system, highlighting what needed to be done, and bid very competitively. They listened to my concerns and talked me through the causes and what could be done to improve them. They estimated it would be a two day job. On the 1st day of install they showed up on time, protected my homes floor, and went right to work. I had hot water and a functional furnace at the end of day 1 and the AC system was also installed. Day 2 was used to install the remaining humidifier, finalize the AC install and fix some duct work that was done incorrectly by builder or previous owner. The installers were very professional and friendly and made sure my house was cleaned up at the end of each day. I'm an engineer and was curious about some aspects of the system and they explained how everything work clearly. They don't just install they understand how the systems work. I was very pleased with the service, the quality of the installation, the attention to detail, and with the comfort of my home after we have used it the past week.

They are expensive and they did have to come back more than once for a job, but they did it to the best of their ability. The one guy misquoted our big job, so I'm sure it wasn't that much cost benefit for them.
Description of Work
Lots of plumbing work, replaced toilets, new shower drain, all of the plumbing into the shower

After fixing the AC wiring problem, the Technician inspected the Furnace since the he knew this older furnace has some issues. Found several cracks on the heat exchanger, which could produce deadly carbon monoxide! Was not asked to check the furnace and Kotz does not sell furnaces. Left after many thank yous with no mention of a furnace seller. Great old-fashioned work ethic: Honest and one who considers the customer FIRST! HIGHLY RECOMMENDED!!!

It went better than expected. Thought we would have to replace the entire unit, Salesman sent to give us a quote took a look and explained that it appeared to be a simple part replacement instead of a total replacement of the unit.

Mr. Josh Thompson was on time at my house on March 25th for the estimate and he acted professionally and seems to be knowledgeable. However, all the professionalism ends there: he promised to send me the quote by March 29th but I never got it. I even called Kotz Heating back on April 5th to check if they were still working on it and I was informed that Josh was on vacation and he would get back to me on April 18th. Today is April 25th and I still didn't hear anything from them. Not that I need it anymore (I already hired another company) but I feel that that was unprofessional.

They worked for us for several years and on a yearly basis, and they're excellent. They were in a transition period between, they were just doing heating, and then they were in the process of adding plumbing. And the only negative we had is we delayed a service call, because he wanted the same service man to come back. They scheduled, they sent that service man, but it's not the service man that came. But the service was fine, we've no complains the whole time. They were very reliable and thorough.
Description of Work
They made us air conditioning, furnace, heating and cooling. They checked out all aspects of the air conditioner and furnace. Replaced filters and just had everything running the way it should be running.

We have used Kotz. They replaced our air conditioning and furnace and then, they service it. The price was fair. It is market. It is not a super sale or anything, but what you get there that you do not get from the other company because it is family owned. Everybody is very courteous and their service people, you feel like you can trust them. If you have an issue, you call them up. They come out and take care of it.
