"We had a wonderful experience with Comfort Energy! The service person, whose name was Chance, did a thorough evaluation of the problem with a focus on saving us as much money as possible, to either repair or replace our 30-year-old heat furnace. He quickly determined that our inlet filter was too dense (it was a Merv 11 and should have been a Merv 8) and that that was probably causing the heater to go off an on every 5-10 minutes. He then tested and confirmed his hypothesis. He also performed a CO test to make sure there wasn't anything more serious going on. Finally, he gave us a good idea of replacement options, which we should probably do before the next Winter, but not necessarily right away. All in all, this is exactly the kind of assessment we needed, and it cost orders of magnitude less than what was estimated by the first service company we had come out. Chance was great, and Comfort Energy is our go-to for heating and cooling service and/or installation from now on."

"The crew from Albert Nahman did a great job from start to finish. The project was to replace the original ductwork in our 60 year old house. Tom provided excellent advice for the estimate then Bryan’s crew did the job, 2 days, within a week of my acceptance of the proposal. Great work."

"Rittinger responded quickly. Alan, the tradesman they sent over was professional and quick. I hired them to install a clothes dryer vent and to open up a vent in my garage for the hot water heater. The work was high quality and installation was clean."

"Pacific Coast Home Services charged me $450.00 on May 10th to have my Air Conditioner repaired. On July 1st when the heat wave hit San Jose my air conditioner did not work. Pacific Coast did not stand by their GUARANTEE and I had to call another company to do the repairs. Thankfully, they were an honest company and made the repairs. Pacific Coast Home Services consisted of their salesman wanting to sell me a maintenance agreement for $900 ... I should have realized at that point he was not interested in fixing my problem and asked him to leave my house !!! He did remove a few leaves from the air conditioner and clipped a few nips off a bush nearby ... there was no repair done for his billing me $450.00. I am 92 years old and feel this was ELDER ABUSE !!! DO NOT CALL THIS COMPANY!!!"
