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.

We very highly recommend Sentry Oil. We had some disappointing experiences with several other companies before we found Sentry, but unlike those other companies, Zach has consistently come through for us 110% any time we've needed anything. We now entrust Sentry for everything we need: home heating oil, furnace, air conditioning, and even a new water heater. Every job has been high quality, performed professionally and in the timeframe committed.

My husband and I had a mini-split ductless AC Unit installed into our home. I had gotten 4 different quotes from other companies and met with many individuals to discuss the job.
Zach of Sentry Oil ended up with the job. He was extremely thorough in making sure the unit would be the right fit for my home. He took a lot of time with me, both through several in-home visits, emails and phone calls. He was extremely knowledgeable and experienced. I had a lot of questions, and he always took the time to give me the information I needed. He sells top quality equipment with an outstanding warranty and

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!

Sentry Oil has been our oil delivery and furnace maintenance for 22 years! They have always been professional, honest, reliable, on time, and very pleasant! It is a family run business and available if you have any issues. They deliver my oil on an automatic delivery system according to our prior usage and the weather. So convenient. You can always count on Sentry Oil!

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!!

I've been using Sentry since I bought my house (11 years). They have been outstanding with their service. My furnace was 30 years old and they kept that thing going for 8 years, coming out at a moment's notice every time it failed. Even when they said I don't know if this will work they got it going again. I can't say enough good things about them. Always friendly and explained everything. When it finally came time for a new furnace there was no question on who I went with to replace it. Thank you Sentry for keeping my family warm!!

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.
