I have had a wonderful relationship with John Nugent and sons. I have been a customer of there's for about 40 years. When we lived in Mclean, VA we started doing business with Nugent & Sons in 1974. In Mclean, when we converted from oil to gas, it was Nugent & Sons who installed the furnace, and air conditioner. In Gainesville, they put in my new air conditioners last year for me and my son.

John Nugent & Sons service call - My experience
Kenny called 40 minutes prior to arrival on site to install the outdoor unit fan motor, we did not answer and he left a message. He knocked on the door and rang doorbell when he arrived, again we did not answer as we were getting ready for work and did not hear. He again knocked and rang doorbell to let me know that he was onsite and that he was about half way through the installation of the fan motor, he wanted to make sure that I knew he was there. After completion of installation of the outdoor unit he knocked on door and rang doorbell, my son answered and he presented his invoice for payment. NOTE; He has yet to come in the house to see if the AC is actually working. My son provided a CC for payment, it was processed and Kenny advised that we would receive an email with the receipt. My son asked if was going to come in and check the system, he said no, the system is working fine.
Question? How would he know this without coming into the house and measuring the temperature of the air at the vent and comparing it to the return temperature? Starting AC: Delta T between 16°F and 22°F. When you start AC, the difference between the current temperature in the room and the air coming out of the AC vents (in HVAC, we refer to this difference as ‘Delta T’) should be the highest.
Running AC: Delta T between 14°F and 18°F. When the AC is running for some time, you should see the temperature coming out of the AC vents lower by about 1°F-4°F.
AC Close To Set Temperature: Delta T between 10°F and 14°F. When the temperature in the room is close to the temperature you set on the AC thermostat, you should see that the air coming out of the AC is not as cold as it was below (Delta T reduction).
My son told me that he had paid Kenny and that he left. I asked if he came in the house and checked the system. He said no, Kenny told him that we needed a maintenance contract for him to perform that work. How can he know that the AC system is working without checking it? Telling me that the motor is running pulling the correct amperage has nothing to do with the system cooling. That tells me that the fan is working properly. I approached Kenny in his vehicle and asked if he was going to check the system, he said no, it was working fine. I asked him how could he know if he didn’t come inside? He said I needed to call the office and get a maintenance contract. He did not check the temperature of the air at the vents. He did not check the indoor unit, the pan, over flow switches, filter condition, nothing. He replaced the fan motor and left. In closing, I will never use John Nugent & Sons again. I will make sure to post this review on social media. I would certainly never purchase or recommend a maintenance contract based on this level of service for a repair call. invoice# 644566 John Richardson
