"They installed a furnace and had to keep coming back to adjust it and even replaced a part. The warranty ran out a year later. But now, a year and a half later, they replaced it free of charge with a different brand."

"I own a business and had a company come out to fix our air conditioner. They came out 4 times, charged for all those time and the unit still was not working properly. I then decided to try someone else, so I called Thermotech on the referral of a friend. They came out, diagnosed the problem within 10 minutes (it was an old crumbling circuit board), showed me that bad part, ordered it and had it fixed in less than 24 hours. We have not had a single problem since! I was so happy with their service that I ended up using them for my home HVAC system.. I even referred them to a family member and they did a home install of a brand new HVAC system and they were very happy with the price, install, workmanship & fair pricing. Thermotech has found a customer for life with me. I have had so many bad experiences over the years with other companies telling & thermotech has been a game changer."

"Computer did the "gotta send info to Microsoft" but when tried to reboot it ran through automatic repair without success. I did all the alternative without any success. He came and picked up the hard drive on Tuesday and returned it on Saturday. Fortunately he was able to "restore" without any data loss. Very happy with outcome."

"Good work on the toilets. They tried to get the rocking toilet to level out by adjusting the bolts but finally the repair person recommended pulling the toilet and starting over. Since the floor was tile, the original tile installer did not level the tile with the drain properly, so the toilet need to be leveled in several areas. Appreciated that the repair person took the time to do the job right! The other toilet had some minor roots in the drain from the ill placed wisteria bush directly outside the bathroom, and the repair person gave recommendations on products to kill the roots. Still having some problems though, and will have to have them come out to go deeper into the line to pull the now dead roots out of the line. And lastly, the faucet that was leaking outside turned out to just be the hose itself was leaking - I thought this was so simple an issue that the call out fee could have been waived on that minor item, no repair was even done, he just looked at it. I put a new hose on it and problem solved. They responded promptly and clean up after themselves very well. This company was referred to me by the home warranty service that I have."
