"I worked with Charles and honestly his attitude and assurance that I?d be working with him sold me on they?re company Well after I signed I never seen Charles again no finish walk through with the client just job is done where?s the money. 26,767.50 for new furnace and a/c I expect an attic access to be finished properly and with quality materials. As you can see they can?t get a mitre corner completed properly. And then use construction grade plywood material NOT good finished grade. So I?ll do it myself the right way. I wonder if Mr. Pelle?s home is finished in junk material like this. If they can?t do this properly who knows what else is done poorly. Another thing the workman asked where I?d like the thermostat I pointed at a location. Well he just starts drilling away and hit a metal vent. Being in design build and construction I know to scan the wall with a stud finder that shows where pipe elec, etc are. Now there?s a vent in a wall with a hole. Zero follow up!!!?"

"Called this company for their $77 dollar, which they advertised with a flyer, for a tune-up and cleaning for my heating system. They are a Hayward company and I was told that our Castro Valley home was not in their service area. I bet if I called to buy a new heater they would be out in a day."

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."

Heating Oil questions, answered by experts

You need to service an HVAC system about twice per year, with a service including an inspection and basic maintenance. It’s best to schedule maintenance in the spring (after the furnace has been running and before the AC kicks on) and in the fall (after the AC worked hard all summer and before winter’s first chill arrives). 

Regular HVAC services will keep the system working as efficiently as possible, saving you money on utilities and larger repairs. HVAC maintenance costs around $250 per visit, while bigger repairs from forgotten upkeep could cost thousands.

Leaks, poor airflow, reduced efficiency, and loop blockages are common problems requiring service.

Most maintenance checks take 2-5 hours, though extensive repairs may take longer.

For most systems, an annual HVAC system service is more than enough. Some homeowners prefer a twice-a-year visit to ensure the system is ready for the upcoming summer and winter seasons. If you need to call an HVAC pro more often than this, it may be time to check if your system is getting old enough for a replacement.

Yes, technicians check refrigerant levels, loop performance, and system calibration for peak efficiency.
