Get matched with top heating and air conditioning pros in Grass Valley, CA

"Mr Spoor does thorough work. He has been in the business a long time and knows the field. I did not know him and called his company to give me a bid on a project. He took time to do some measurements and convinced me of a better course of action. I respect his knowledge of the field and will call him first."

"Great price, quick efficient service. Very satisfied"

"Found Justin very easy to work with. Honest recommendations ie: short term fix or long term purchase. Haven't made up our mind yet and have not been pressured in any way. Whatever we decide, we will be hiring Justin."

"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."

"The team was respectful of my property and worked diligently to ensure that the project was completed within the timeframe and budget we had discussed."
