      Go to bad referral area. They separated them. There are almost 300 horrific complaints.

      The intelligence card they said was $797!!

      Molly completed today our first annual maintenance to our furnace. She was patient and answered our questions. She was knowledgeable and very kind. Each technician that has come to our home has been equally professional as we replaced this past year; furnace, hot water heater, central air, and sump pump/backup system. We highly recommend KOTZ to family and friends. Thank you, KOTZ and Associates. Joe & Myriam Manrriquez

      Wow! What an incredible experience. I was referred to the Kotz team by a coworker when my ELDERLY VETERAN father needed the entire house redone. I wish I could have given them an even better rating but 5 was the most amount of stars possible. They were upfront about the entire process: HONEST hardworking people. They kept him involved the entire way and even followed up a week later to ensure that everything was working properly. Costs were extremely fair and they did fantastic work. I have taken the "cheap" way out before and that is why I needed to have all of the work redone. Great service, fair, honest, smooth process. I cannot say enough about how incredible and caring my technician was. I could tell he treated my father like he treats his own. 10/10!

      Horrible. Have used Kotz in the past with no problems. Both furnace and water heater. This time had to schedule 2 weeks out for a kitchen sink and told it would be between 10-4. Fine. Took time off to be home. At 1pm had to call to see if everything was still on track. Talked to Riley. Was told no notes by the tech so everything should still be a go. At 2pm was called by Teresa and told that the tech 'was having a problem' and I would have to reschedule for next week. Told her no thanks but thanks for wasting 3 weeks of my time including a whole day off for a no show.

      Couldn't have a more opposite opinion of other reviews. While Kotz isn't cheapest group around, the quality of the service, the professionalism and punctuality of their people, etc. has always been great. They always clean up and make sure everything looks the same or better then when they came. Technician even offered for me to sit with him to watch what he was doing and inspecting. Have used them for new installs and ongoing maintenance and never had an issue.

      BEWARE!
      Kotz charged us over $700 for a simple blower motor replacement, they got lucky because I was out of town and called them and needed the furnace working again for my wife, had I been home I would have found many reputable HVAC companies that said they would have only charged me about $300. Kotz does that so you can get a $400 credit towards a new furnace IF you purchase one within two weeks of the service.

      Be very cautious considering a 'service' plan. We paid up front for 3 years over $500 for twice a year service. Nick, the guy who came to service was great.

      But, when trying to schedule service, it's a 2.5 month wait every time. For maintenance service, that was paid up front. It's a classic take the money and run.

      Based on this, I would recommend to NOT do business with them at all. We were told if it was an emergency, they could get someone out here sooner. I assume because that would be paid work.
      If my HVAC fails, I will NOT purchase or have them install or ever service.

      When we asked for a refund of the balance of the service plan, the lady (her name was Star) got very rude with my wife on the phone.

      !!!!!Poor business practice!!!!!

      Very dishonest business. Came to my house and charged my AC unit with 1.5 Lbs of R410. I was charged $514. Never fixed the leak as I was asked for $369 more for the die! Two days later I called someone else who came added the die for $90. I asked how much it ccharge for refrigerant? The response was $80 per pound. I do not recommend .

      We were charged 224.00 to be told that our AC unit was freezing up because we use a 3M furnace filter! It took Anthony 1 hour to tell us that. So, we were charged 84.00 service "diagnostic fee" and one hour "labor fee". We will NEVER call this scam of a company again. Oh, and I called to make a complaint and was told the managers were "in a meeting ". Yeah, okay. If you dont work hard for your money and enjoy tossing it out a window, then give these guys a call!

      Scam, They prey on the elderly. DON'T BUY A SERVICE PLAN!

      An elderly family member has kept a service plan with KOTZ for several years, maybe decades. I moved into her house when she became ill and received a postcard from Kotz saying her yearly checkup had been prepaid the previous year and I needed to schedule. I scheduled it that week. I thought great! They'll come out, clean the furnace and AC, maybe make some adjustments, fill a little Freon, change the filter and let me know if there were any major problems. Everything had been working great, cold air, and no problems. When the tech showed up, ALL he wanted to talk about was getting me to pay upfront for service calls for the next 3 yrs. She had paid $279 for this one yearly visit- he offered $600 for 3 years. I asked what was included and was told absolutely NOTHING was included!! The $279 covered him to come out. It didn't cover any adjustments, filter or Freon. I asked, why wouldn't I just call if I had a problem? He said I could but there was a $125 service call fee- THATS LESS THAN HALF OF THE $279!!! He did an inspection and said he could add Freon and change a capacitor (just because) and it would be $400-600 depending on how much Freon he needed. If my aunt had been there I'm sure she would have been worried and payed the $400-600 plus the $600 service plan renewal. I told him to get the hell out of the house. The furnace and AC has worked flawlessly now for a year without his recommended repairs. They should be asshamed
