"Jack Smith came by to look at our unit which was not functioning properly as it didn't cool. He fixed it for less than 15 minutes! He was very courteous, wore a mask and even put on shoe covers when he entered the home which was greatly appreciated since we have a newborn in the house. We couldn't be happier with the service. Highly recommend!"

"I had an outstanding experience with Keith from KCAC Home Repairs. When my A/C was on the fritz, Keith came to the rescue, and I couldn't be happier with the service. First and foremost, Keith was incredibly easy to work with. His professionalism and communication throughout the process made it a breeze. He took the time to explain the issue and the necessary repairs, which made me feel confident in his expertise. What truly impressed me was how quickly Keith got the job done. He wasted no time in diagnosing and fixing the problem, demonstrating remarkable efficiency. In no time, my A/C was up and running, cooling my home like it was brand new. I can't stress enough how satisfied I am with the service provided by KCAC Home Repairs. Their speed, efficiency, and the end result â my perfectly working A/C â left me thoroughly impressed. If you're in need of home repairs, I wholeheartedly recommend Keith and his company. They're the epitome of professionalism and excellence in their field."

FAQs for central a/c service or repair projects in Knoxville, TN

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.
