"Aldo came to the job site the next day after we spoke by phone. He sent a quote for the work later that same day. He completed the project (replacing 2 gas wall furnaces) in a single day and the heaters were working that night. He was prompt, reliable and easy to work with. I highly recommend him."

"Carlos and his team were absolutely fantastic! I had a significant leak under my home, and he was the only contractor to respond quickly. He provided multiple detailed options for additional work I had requested (copper re-pipe and connection to the water main, sewage line repair) and was not pushy about any particular solution. Every step of the way he explained why he was doing what he was doing and showed me the progress; I learned a lot in the process! The piping in my crawl space is now up out of the way and was beautifully done. Carlos even updated some of my outside valves and was very thorough about back-washing all the sinks and cleaning the filters to remove any leftover particles in the lines when the work was complete. Most importantly, he showed up when he said he would, completed the work when he said he would (just 2 days), made repairs to my irrigation system, and put everything back the way it was (including my yard!). So glad I went for the updated piping; it has made a world of difference in my water flow. I would absolutely call High Tech Plumbing for any future work and I would highly recommend them to friends and family."

"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."
