Message from the Owner/ Founder: “As a third generation heating and air technician and retired 20 year veteran of fire and public safety, I wanted to create a service company that you could count on for its integrity and professionalism. When our service technicians arrive at your home, we want you to feel the same level of confidence and trust you get from a firefighter arriving at your home to help when you call 911. Our service technicians are professional, courteous, and well trained. I am comfortable allowing them into the homes of my families and friends who are firefighters, police officers and the public. Thank you for the opportunity to service your comfort needs and believing in our company. We look forward to a continued long relationship. Warm regards, Harry Abbott” Comfort Energy Inc is a full service provider of quality air conditioning and heating repair and installation. . Locally owned and operated, with over 30 years of experience. We are proud members of the Nexstar network of contractors. We specialize in helping homeowners make informed decisions to best meet your family's comfort needs. Spanish and Japanese spoken.
"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."

"Venice the technician was friendly and was able to quickly diagnose the problem which was the hose that connected to the pump broke and it looked pretty old. Since we couldn’t just replace the connector to the hose, getting a new part was the best choice."
