"Precise HVAC was wonderful. I actually was going to get more quotes but after working with their salesperson I decided to not even bother. They answered all my questions and made suggestions for things I didn't know about. I'm not even sure I care if I got a better quote or not. With Precise I know that they cross the t's and dotted the eyes and I don't have to worry about missing something."

"I needed quick service on a 45 year old hot water boiler in a 1938 house I recently purchased. While I could get the pilot light lit, nothing I did could get the boiler to fire (water was circulating).
On Wednesday I contacted Pelletier Mechanical as Gary (the owner) had been out giving me estimates on the various repairs and modifications I wanted to make. While Gary was out of the office training (again), Laura his admin arranged for Bill to come out on Friday. She provided an estimated cost (right on) and a 2 hour window.
Bill showed up on time and after a brief discussion get right to work. Bill spent about 15 mins. systematically determining why the flame would not light. He discovered that there the gas was not making it to the main control valve. He reset the safety shut off valve and the problem was solved. He then checked all the radiators to make sure that hot water was making it through out the house. After we determined that the upstairs radiators were not getting hot, Bill checked the water pressure and determined that the pressure was insufficient to fill the upstairs radiators in "real time". He suggested that the culprit was the 45 year old water valve and pressure release valve which being cast iron tend to corrode and clog in time. He proposed a replacement solution and priced it out, and offered to pick up the parts and replace the valves that afternoon. I decided to wait a few weeks so I could consider replacing the entire boiler.
While we were waiting on the boiler to come up to heat, Bill and I walked through the basement looking at the existing plumbing, tracing the water flow path and discussing the possibility of replacing the hot water tank with a tankless unit. (The hot water run is about 60-65 feet from HW tank to kitchen, bathrooms, etc.) Bill, like Gary, is knowledgeable and informative.
I will have Pelletier Mechanical back to do more work on the house."
