"Well the technician got there in the allotted time frame, called 30 minutes before he came to let me know he was on his way, very promp, professional service Tech, I told him I wasn't interested in any high pressure sales for a new unit, just wanted it fixed. Byron was excellent. He understood my apprehension and assured me Hufts is not all about the sale, its the service. I was very impressed as being a first time home owner I was expecting the worse and had my game face on. But to my surprise no pressure at all, I know in the future I will need a new unit and I will definitely contact Hufts for my purchase and install, will highly recommend as they were to me. Great experience!!!! Thank You Angie's List!!:)

"Internet connection was weak, garbled communication. But, they remained very professional and we could crack a joke every now and then when things got annoying. Once up and running the diagnostic test was done in 5 min. Confirming my suspicions. Part number was sent within minutes."

"Hired to remodel 2 bathrooms. I should have hired Arayik to do the tile in the showers and floors only. The tile work was fine but electrical, plumbing and woodworking was unacceptable. Electrical outlets that were relocated had to be reset and wall repairs had to be redone to allow texture and paint to be done. Base boards installed by Arayik had very uneven gaps above tile floor and had to be replaced."
