Thermostat Installation Companies in Concord, CA

"Edgar was a pleasure to work with. I would definitely recommend him."

"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."

"Pleased with every aspect of the job."

"Nice discussion of options that was balanced and thorough."

"Thank you Eric for getting me in your schedule so quickly, being on time and getting my heater working! You did a great job fixing my wall heater at a reasonable price and I now don’t have to shiver the rest of the winter. Most others I have had come over have tried to convince me into getting central heating as my only option, but you were able to make my wall heater work again (and quickly). The best part of this experience was how professional, courteous & knowledgeable you were. I will definitely work with you guys again!"

"Very responsive company. The owner Said is very customer service oriented. I had 411 install a first time air-conditioning system in our Concord home. He explained all my options with the compressor and ducting, which he recommended to be removed due to the asbestos taping and age of the house. We went with a two stage unit unit which is keeping our home nice and cool and I was really surprised that our PGE bill didn't go up any more then what we were experiencing with the two portable AC units we were using in our bedrooms. Would definitely recommend 411 to our friends."

"Quick response and reasonable prices"

"The service was wonderful! Scheduling was very easy and accurate and the technician was timely, knowledgeable, honest and direct. I would highly recommend this business."

"Called Trio Heating on a late Friday afternoon and they sent out two technicians (Jose & Dallin) the next morning to fix a gas heater that would not turn on. Their communication from beginning to end was great. They sent me a text 45 minutes before their arrival time and I was able to track their ETA which was extremely helpful. They explained to me what the issue was. I was able to run out and buy a new thermostat for them to install. They did a great job, cleaned everything up and put everything back together. They also typed up everything they worked on and took multiple detailed photos of the unit and emailed 10 minutes after they left. I think what they charged was extremely reasonable for the quality of work. I really appreciated not being charged a higher fee for coming out on a weekend. Will definitely use them again for my HVAC needs!"
