"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."

"I was extremely impressed with the service provided by Air Sharks, who replaced my aging furnace and damaged heat ducts. Elizabeth provided a detailed explanation in a friendly, professional and understandable way. Pricing seemed reasonable, and was 25% below a previous estimate. Daniel and his crew did a fantastic job removing and replacing the new furnace and the duct system in a very tight crawl space. They left the furnace looking absolutely beautiful and clean. I highly recommend them"
