"⭐️⭐️⭐️⭐️⭐️ I want to start by highlighting the *above and beyond* service I received from Keep Smiling Heating & Air. In the midst of a brutal Atlanta heatwave, I called in a panic because my newer AC unit had suddenly stopped blowing cold air. From the first point of contact, the experience was incredibly professional and reassuring. I received a confirmation text, a follow-up call when the technician was in route, and even a text introduction with a picture and background info on the technician. Who does that? **Keep Smiling does.** Technician **Byron Solares** was exceptional—knowledgeable, professional, and genuinely empathetic. I explained that I have my elderly father with a breathing condition living with me, and Byron not only resolved the issue efficiently, but took the time to explain everything clearly. Thanks to his quick work, we’re resting comfortably tonight."

At Casteel Heating, Cooling, Plumbing and Electrical, we provide world-class service to our customers, just as we have since 1987. Founded by Jan and Bob Casteel, our company was built on honesty and customer-focused care. To this day, we offer our Amazing Care Guarantee: We’ll take amazing care of you or we’ll refund your service call fee. Our expert team of plumbers, electricians, HVAC technicians, and system design managers performs top-quality repairs and installations while ensuring you are completely satisfied with your entire customer service. Because we offer so many services under one roof, you’ll save time and money by making one phone call to Casteel. Formerly: Knight Air Conditioning and Heating Company

"The heating was fixed but I am very unhappy about the pricing and lack of transparency. The service technician tried to upsell me a $200 safety valve that I “absolutely needed” (but online said should be able to be installed for less than $50 and was just another added feature to shut off the AC if the drain was clogged). The technician said he would not charge me for the repair on my dampener but I got a $40 charge anyways after refusing to pay for the safety valve, which I said I would buy myself. When I had spoken with Casteel on the phone the night before, they said the $40 charge would be for a second HVAC unit, which ultimately did not get serviced. I never received a detailed explanation of these charges and instead said this was a “miscellaneous fee” for repairs. They got the job done but I do not think I would hire again solely because I felt like I was being taken advantage of for most of the visit. I could not get the $40 charge removed after calling Casteel and explaining the situation. So it was a $129 service call with no parts replaced more expensive than other providers."

FAQs for central a/c service or repair projects in Lawrenceville, GA

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.
