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."

FAQs for central a/c service or repair projects in San Jose, CA

A condenser fan motor is a crucial part of your air conditioner that prevents the compressor from overheating. It pulls heat from your AC unit to cool the refrigerant moving through the condenser coils. This allows your system to blow cool air and keeps everything running smoothly.

The most common causes of AC fan motor failure include loss of lubricant in the system due to overheating and a rusted or leaking run capacitor. Poor lubrication can also cause failure in the belt drive, which may impact the AC fan motor. Weather and electrical components can also affect your AC. For example, a storm could send water into your motor windings and damage the internal components.

Air conditioner fan motors last about 12 years on average, though they can last longer if maintained well. This includes keeping them clean and cooled as needed with annual air conditioner checkups. Routine maintenance is essential to catch AC fan issues early. An HVAC inspection can cost between $70 and $500, while AC cleaning services may range from $100 to $400.

A broken AC fan motor may need replacement because this part usually can’t be repaired. Several things indicate it’s time to replace your AC fan motor, including buzzing noises, a constantly running fan, unusually high energy bills, or an aging system. If you notice these signs, call an HVAC pro for help before the faulty motor starts to strain other parts of the AC system.

There are clear warning signs of a bad AC fan motor, including unusual interruptions in the fan operation. The motor might be malfunctioning if you hear weird noises like grinding or rattling or if the fan continues to spin when the unit is off. These indicators compromise your AC’s cooling performance and increase your energy costs. Addressing these issues immediately by contacting a trusted HVAC professional prevents further damage and safeguards your HVAC's efficiency.

Replacing your AC fan motor takes a professional one to four hours. The technician will start by assessing your system and safely removing the damaged motor. If a new part needs to be ordered, it might take a few days. Once the part is available, your pro will install it properly and make sure your system is running smoothly.
