"I looked at a number of different options and they had the best pricing and they also specialize in just doing central air. So they were also sort of a plumber and gas fitter, anything like that, and so they really specialized in what I was looking for. So that is sort of their core business. They were good and they did a very nice, clean job. The house was built in 1901 and so they did a great job of removing the old radiators and radiant based heat systems and replacing it with a new central air set up."

Customers say: Super punctual
"I did everything I can to clear the blockage in my kitchen sink drain but it is totally blocked. I called Milltown Plumbing in the morning and they expected to send someone over later the day or the next day depends on how quick they can finish other works. They keep me updated when they can send someone over on the same day. Pedro came and fixed the blockage in no time with no mess. He is professional, kind and considerate. I'd rate their service 6 stars if it exists."

"My initial inquiry to Pinnacle to get a proposal on installing central a/c in our 1935 home. Of the various companies we met, Pinnacle was the most responsive and best understood our needs. The advice we received was fantastic and led us to make decisions that were absolutely the right ones for us: two zones with heat pumps, a third area with mini-split. The installation crew was respectful of our space amidst the disruption that is naturally going to occur, and always very pleasant to have around the house. I was so impressed with the work that I went on to have an aging boiler replaced with a new Viessmann boiler and am so pleased to have made that additional investment in our overall HVAC systems. These guys really are the best. I'd be happy to be a reference."

"My central AC system had gone several years without service so I wanted it brought back to peak efficiency and this is exactly what Jay did. After changing some parts and cleaning it, he pronounced it as running perfectly. Jay was very friendly, courteous and professional and his can-do philosophy assured me that the system would be running well and I could depend on them to keep it that way."
