Zack and Matt and their crew installed a Mitsubishi air conditioner in my home today. They were in and out in less than 4 hrs with the unit cooling like a champ when they left. I was very impressed with their knowledge of the product and the quality of the workmanship they delivered.
Thanks guys. Steve Burke Jefferson, Ma.

So if you are looking for service this is the company to use. My heat hadn't been working for a couple days, had another company look at it. Twice. I literally called at 8 this morning and they had Zach here at 11 and he fixed the issue in literally minutes. All this amazing service and I wasn't even a customer. Until today. Loyal customer as of today. Thanks guys for being awesome!

Had a furnace issue during a Nor'easter. Their team showed up within an hour, diagnosed the issue and we had heat back within the hour. We have used Sentry for years, and they always provide fast and affordable service.

Sentry came to my rescue this morning after I ran out of oil and had no hot water. They responded quickly and went out of their way to help me. Their business ethics and standards are outstanding! To Brian and staff, thank you again!!

Well, if your service is anything like the way one of your techs drive, I give you a thumbs down. It's probably not a good idea to cut someone off and squeezing them out of a lane and being reckless in your bosses' truck. Heck, maybe you were the owner. Dave, you are not alone.

Did business with them for about 10 years, but not anymore. The technicians that came out were pleasant and very helpful. The owner is not a fun person to deal with.
