Get matched with top central a/c installers in Graham, NC

"The technician cleaned and calibrated the air conditioner. He pointed out that we had a part that was aging and could possibly fail at any time. He asked if we wanted to replace it. We told him to do what he needed to do to get the air conditioner working at full capacity. He quoted a price of $132. After checking our account, he returned to tell us that the part is covered under the 10 year warranty. He was very thorough and meticulous with his work.
We have dealt with Duggan for 8 years and had our unit serviced spring and fall each year. The office always communicates with the customer and let you know when the technician is on the way. During the eight years, all the technicians were knowledgeable, professional and  are always very polite. They wear shoe covers when in the house and leave their work area clean.
Highly recommend Duggan.

They have installed 2 air conditioners in the past in 2 different years followed by water heaters. Happy home is reliable and trustworthy and truly a joy to work with from start to finish. Ananya"

"Excellent service! We had a problem with our HVAC unit that had persisted from the time we bought the house, almost 3 years ago. In fact, a discount was given us by the previous owner due to problems that existed with the HVAC system. Over a span of 2+ years we have had the unit looked at, serviced and repaired by three different companies, but each time the problem would eventually return. The technician from Miller services however, dug down until he identified the underlying issue that had been affecting the operation of the unit for years. From the time of the repair and through one of the hardest winters I have experienced in this state over the 67 years of my life, our HVAC system has performed flawlessly. I would recommend this company to anyone needing HVAC services of any kind."

"Estimate was quickly provided and job was done within estimate range. Installers were very knowledgeable and had quite a bit of experience with whole-home systems. They arrived on time and took the necessary time to do the install the correct way. Would highly recommend."

"Jim with North Alabama Technical Services removed some items from my computer so that I could send emails and attend to items I needed to address that day. As planned, the next day he thoroughly cleaned my computer, he also made helpful suggestions while working on my computer. I would call him again if needed and I thought the fee was reasonable."
