"I called ThermoTech Solutions and they sent out a technician within 24 hours. I was pleasantly surprised that the technician was the same gentleman I talked to over the phone so I did not have to retell what was wrong with my system. Jason my technician who is also the owner was great. He tested my system, knew exactly what was needed, and had it repaired the very same day. He did not try to sell me on upgrading my unit or a bunch of repairs I did not need. The service was fast, very reasonably priced, and I have had no issues since. Will definitely be having ThermoTech Solutions come out for all my HVAC needs in the future!"

"Called this company for their $77 dollar, which they advertised with a flyer, for a tune-up and cleaning for my heating system. They are a Hayward company and I was told that our Castro Valley home was not in their service area. I bet if I called to buy a new heater they would be out in a day."

"Very disappointed. This guy is a crook. I paid way too much for what he did and he did not do the work properly. He replaced pipes that were leaking from our upstairs shower. I had another leak a few weeks after he did the repair. 2nd leak was not related to the pipes he repaired, but the 2nd plumber who came out for the 2nd leak had to cut into the ceiling where HK&S Plumbing replaced the pipes and told me that the work was not done properly. He did not glue the pipes properly and he used a rubber coupling that is not allowed in California. The other plumbing company said they would fix his work for 65% less than what I paid HK&S. When I asked HK&S about all this, he gave excuses about the small space and how much more work it would have been to do the work the right way. When I asked him again for a refund, he is now saying his work will last "forever" (really?) and has nothing to say about what he did wrong. He is not giving me a refund. Not sure I will use anyone thru Angi again."

"My AC stopped working last November, and since then i had 4 contractors i called to fix it, i was turned down by everyone. i called Tyndall and peter came out and talked about it with me, actually troubleshot it, and 2 days later had parts and fixed it. i would give them 6 stars if i could. im so glad to have my ac running again. my recommendation, if you want something done, call Tyndall, because the rest of the contractors seem to just say its not fixable and leave without even looking at it. these guys were the first people that listened, then looked at the unit before declining service, and then actually fixed it. 10/10 great job and thank you."
