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."

"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."

FAQs for central humidifier installation and replacement projects in San Jose, CA
Unless you have advanced HVAC, plumbing, and electrical skills, hiring a pro is worth the investment. Improper installation can strain or even damage the furnace, leading to repairs that dwarf the cost of professional labor. Certified installers deliver a precise, code-compliant setup and help the system run efficiently for years.
Your whole-house humidifier choice comes down to budget and upkeep. Drum models cost less but demand frequent pad changes and vigilant cleaning to avoid mold. Flow-through units carry a higher price tag yet need less maintenance because water drains away rather than sitting in a reservoir. Decide how much ongoing work you’re comfortable handling before you buy.
Whole-house humidifier repairs average $230 but can reach $500, based on unit type, repair complexity, and local labor rates. Systems tied into extensive ductwork or large homes tend to cost more to fix. Routine maintenance, like the occasional pad change, cleaning, and inspection, helps you avoid those higher repair bills and keeps the humidifier working longer.
If indoor humidity regularly falls below 30%, a whole-house humidifier is a smart upgrade. Dry air aggravates allergies, chapped skin, and static, while ENERGY STAR recommends 30% to 50% year-round (30% to 40% in cold climates to curb condensation). If levels climb above that range, consider a whole-house dehumidifier instead.
A well-maintained whole-house humidifier lasts for 10 to 15 years. If yours is pushing a decade and performance drops or energy use climbs, start planning for a replacement. Upgrading boosts efficiency and indoor comfort, and an HVAC pro can confirm whether repairs or a new unit make better financial sense.
A whole-house humidifier is installed directly into your HVAC system and positioned near the furnace or air handler to maximize performance. It connects securely to both the ductwork and plumbing systems, ensuring complete integration. Hiring a professional guarantees a safe, efficient, and permanent installation that protects your system from future operational issues.
