We joined Angie's List in August of 2007 and have earned their Super Service Award every year since 2009 when they started that program. HARP Home Services, LLC is here to take care of all your heating and air conditioning needs. Whether you are looking for a free quote on a new central air conditioning system or are ready to install radiant floor heating or a new boiler for those chilly winter months, we're just a phone call (or e-mail) away. Residential & Commercial.

"This is the latest after HARP has been out to try and fix an AC system they installed. Mind you 4 different technicians have been to the property and none seem to have been informed on the repair or what it would take to fix it. I had another AC company come out an inspect the unit HAAP installed. This is what the report stated: ent to look at heat pump system in the apartment. Outside I found the condenser line set to be kinked, uninsulated, the wrong size and the system to already have dye added to the system so someone has tried to leak check the system. The problem with the dye is that it should never be used in a system because it contaminates the refrigerant and the oil in the unit, these actions have taken years off the operation of the unit. Inside starting at the thermostat to be wired incorrectly which may be a leading cause to why the system is running incorrectly. Also found that part of the ductwork was cut out of the way by the previous company and they did not put the duct work back together and in fact just covered the whole on the end of the duct. The line-set is wrong as it is suppose to be 3/8 3/4 line-set and it is only 1/4 1/2 line-set which leads to less life of the system and improper running of the system. In order to fix the system we would have to reclaim any refrigerant from the system and then un do the brazed connections, run line hide, drill out the building pull new thermostat wire and a new line-set between the two units, braze pull a vacuum, charge the system and then re wire the system.

FAQs for central a/c service or repair projects in Guilford, CT

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.
