Air 1 Heating and Cooling takes pride in our heating and air conditioning expertise. We ensure optimum quality and customer satisfaction, with every project. Call us for a free estimate on direct replacements and new installs of equipment. We offer 24 hour emergency service.

"They installed our unit in March 2015, and the unit induced motor was found to be defective in Nov 2015. They not only charged us for the service call but also charged us for the part which was under warranty. It was very unprofessional. The same part after less than 5 years failed again, and they took no responsibility for their workmanship. Customer service Person does not deal with the customer on the request. This time again they were charging us for the defective part and exorbitantly for the service call under the pretext that we did not sign a maintenance contract with them. So we did not finally go with them but went with another vendor who is far better and professional."

"Changing my 5 star review to 2 stars. We have had a HE Boiler as well as a AC/Heat Pump installed by them. Unfortunately we needed service today. I was willing to pay for Emergency service. They said they couldn't make it out for 14 days, because we did not have a service contract. Spent about $25k for the installations. Which apparently means nothing to them What makes matters worse, the Emergency Service we paid through another HVAC provider was only necessary because of an issue they created during the installation. During the installation Speer Air originally ran the line for the residual pump over the copper hot water line. Which over time burned through the residual line, and then cause a hole and leak on the copper pipe."

"This company will try to rip you off any chance they get. Scheduled non-emergent repair/service of my humidifier on their website. The tech was on time, professional, and cordial. I informed him the humidifier was not operating correctly and the water inlet valve may be stuck in the shut position. After 30 minutes he informed me the humidifier was running but the inlet valve was now leaking water onto my water heater and would need to be replaced. He proceeded to call the office to see if a plumber could come out and to get an estimate for the work. After 20 minutes they said one of their plumbers could come do the job for $600. I immediately said no thank you and informed them i would get an estimate somewhere else. They then said they could discount the work by $100. Making it $500 to replace a $30 valve.

FAQs for central a/c service or repair projects in Mendham, NJ

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.
