"He reattached the air condition hose to the vent but never came back with the part he said I needed and would not return my calls. He never finished the job. I hired someone else to complete his work. Beware."

"Shawn Thompson did a great job diagnosing our AC issue and repairing it promptly. He is an above-and-beyond the call of duty kind of guy who came out after hours to help us out during a heat wave. I couldnâ t recommend him more highly."

"Young man who came to do the job told us that they sent him to 3 wrong houses before they found ours. He proceeded to unclog the drain in the basement using the mechanical drain. Took him maybe an hour to clear it and also ran our sinks and toilets to make sure we wouldn?t have another problem. The young man left our house, however proceeded to sit in his running van, parked in my parking spot. I had no issues with this service until I saw the bill. $1000 to snake a drain for an hour? When we inquired about the bill they told us that their rate is 300$ an hour and that the job took 3 hours. In my opinion, if it takes you 3 hours to snake a drain, then someone should be fired or retrained at their job. My assumption is that their scheme involved sending this young man to multiple wrong houses and him sitting in my driveway for a prolong period of time, so that they could charge us for 3 hours of ?work.?

FAQs for central a/c service or repair projects in Harvard, MA

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.
