We recently had our 24 year old HVAC system replaced in our home with Carrier 18 SEER variable Heat Pumps and eFurnaces. We had originally planned to replace our Furnaces and Compressors but unlike other companies Lar came out and explained in detail - very simply - the difference in functionality and efficiency between our current system and a variable heat pump/blower/coil system. He examined what we had and where the new system components would be installed, taking into account all codes and checking potential issues with the inspector real time beforehand. Henry the owner even came out to check potential issues within minutes...There were no surprises whatsoever! The cost to replace our current HVAC system with Heat Pumps vs. furnaces and compressors was the the same, except there are no rebates when replacing furnaces. However, we will be receiving 11.5K in rebates total for installing electric heat pumps. In addition we won't be paying gas for furnaces and heat pumps are way quieter and way more efficient than our current compressors!Product and labor warranties second to none! John & Alex did an amazing job on the installation. They were super professional, clean and respectful and completed the job in a very timely manner. They even installed an additional vent in our family room a no cost! Andrew has been with us every step of the way regarding rebates...Our experience with Therma Tech has been a delight and we highly recommend them! Excellent teamwork across the board from start to finish -- an outstanding organization!Tracy and Juvy Zappel

Therma Tech recently installed an HVAC system and replaced all the ducting in my home. From the estimate to the installation I found Therma Tech to be a quality company with excellent employees. The discussion of the project and the estimate was with Lar who I found to be knowledgeable and an excellent communicator. He worked with me to understand all aspects of the project and installation I greatly appreciate the time he devoted, and for providing the written estimate the same day as his initial visit. Jose and Jesus who were responsible for the installation were outstanding as well. They were very pleasant to work with, timely showed up promptly at the same time each day, and worked very hard to complete the installation as soon as possible - providing heating a day earlier than I expected. They were also careful with my home, and cleaned up the space every day.
