Our mission revolves around providing transparent, competitive pricing, ensuring every task is executed with exceptional precision and a focus on detail.

"Be cautious of Radiant Plumbing and AC's deceptive pricing practices! Avoid hiring them! here is my story: I hired Radiant Plumbing and AC, based on their advertised $40 introductory visit fee, to check for a water leak issue caused by the clogged AC drain pan/drain line. The technician verbally quoted $67.10 for cleaning up the clogged drain pan/drain line, but the final invoice was $671. After arguing, he explained that the $67.1 was mentioned as a saving amount. This misleading tactic makes me believe and proceed with the service. If he said clearly that $671 was final, i wouldn't have chosen them as it is way over-charged. I then try to call the office but never get a reply back."

FAQs for central a/c service or repair projects in Round Rock, TX

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.
