Friendly and knowledgeable staff. They came out and installed a new furnace and AC unit for a great price!

Great service. Honest people. I’ve used them for multiple properties I own and they’ve been great.

First class install of new heat pump. Shawn and his crew were so nice to work with. Highly recommended

Able to come out same day and fix the air conditioner with one small part! He even cleaned out the unit. Helpful, quick, and reliable! Thanks!

Quick, friendly service. Thorough technicians. This is a family owned business and you can really feel that. There are many ways to pay your bill with ease. I'm way more than satisfied with this company and will not go anywhere else. Thank you so much!

Central air unit was acting up on friday7/16 …. And one phone call to Kate in the office got the response we needed… the techs Steve and Aidan were professional and solved the problem pretty quickly… we have been customers of Duffeys for 35 years and I would recommend their services to anyone!

Its too bad there isnt a Six star rating because this company deserves it. They are always very fast with service calls, ie my oil furnace problems, the tech guys who arrive are polite, knowledgeable and get the job done right, and are happy to point out the details of how the equipment functions.

Had an issue with my furnace on a Sunday. Sent an email inquiry and they responded immediately on Monday morning. Came out same day and diagnosed and fixed the problem. Friendly and upfront about issue, options and price. Highly recommend.

Amanda is always comforting and professional on the phone when I call. Dan came out to fix my heating system after my hot water component stopped working. He was kind, professional, and efficient.

Excellent customer service!
Returns calls. A valuable tool to all customers.
Good communication and expert in providing details to our heating system and service.

Joe and his crew spent two days installing a Combi boiler to replace old boiler and water heater. They were on time, cleaned up, and the installation looks great. Joe explained how the unit operated and marked all the shut-offs and pipes. I can't comment yet on the unit itself yet but the company takes their work seriously.

As a naive new homeowner, I ran out of oil right when it got cold. I called DE Duffey and had my tank full and heat running in an hour and a half, including the bill settled. I also appreciated that they didn't try to sell me anything except the service I asked for. I will definitely continue to do business with this company.

Duffey has a customer for life in me! They recently installed two Weil McLain boilers in my home and had a team work in a couple days to get the job done right. It’s refreshing to have a professional job and receive what you expect when hiring a company. Thank Duffey team!

Great people who work here. 4 employees from Duffey hopped out of their work truck to assist my wife and the police who were broken down on side of the road. Really appreciate it and will be calling them for our next service. Thanks to those workers at ridge and butler.

I truly could not recommend this company enough! I recently purchased a home with oil heating and was unfamiliar with what it entailed. Not only did they send someone out to check on my system, but they were incredibly honest/transparent about how much oil I REALLY needed to purchase to heat my home (i.e. didn’t try to upsell me even though I was clearly in unfamiliar territory). The tech and his partner who were sent out answered every silly question I had and were incredibly kind and respectful. The team at DE Duffey is knowledgable, professional, and epitomizes what it means to have good customer service. I’d give 6 stars if I could!

Pete and Joe's team did a great job installing our new heating system. They had a few guys come out so it was nice to get the job done in less than 2 days. We were very comforted by Ken's knowledge in explaining what system would be best for our house too. Thanks all!
