  • 5 star review  What a great team! Easy to work with over the phone (and they answer the phone and keep in touch as needed) and their team shows up on time and solves problems, communicating well along the way. And they charge very reasonable prices. I will continue to use them for all of my HVAC needs in my home and other properties.

  • 5 star review  Gelinas is a great company! They have done some plumbing for me and fixed my furnace. They are always available when you need them. I have referred them to many friends because I trust that they will do a great job - quickly, but right.

  • 5 star review  My heater had become unreliable and needed maintenance. I was a little stressed because it needed to happen ASAP and I had a busy week ahead. However, my technician, Ron, was able to come right over and get the heater working properly again. He also pointed out where the concerns were so I could start planning future purchases and maintenance. I am so appreciative of Ron and Gelinas' responsiveness, attention to detail, and follow-up.

  • 5 star review  A few weeks ago I called for a plumber and spoke with Gary. I told him I was having problems with my water pressure. He gave me some tips over the phone to try to fix it. When that didn't really work he came out to take a look and figured out that I needed the whole pump replaced in the well. He recommended who I should call to have the job done. It was fixed the same day. Gary did not charge me at all for his visit and diagnosis. I love Gelinas and Gary is a big part of the reason.
