Customer Testimonials

Great company for heating oil and HVAC needs. Staff provides excellent service and is very friendly and courteous. I have used them since 2018 and will continue to use them going forward. Can't recommend them enough!

I have use Cromwell Energy for over 20 years and still couldn't be more pleased with the service I received for both my air-conditioning unit and boiler. The team was prompt, professional, and incredibly knowledgeable. They always take the time to explain what was needed to be done, answered all my questions with patience, and made sure everything was running smoothly before they left. Cromwell Energy clearly takes pride in their work and truly cares about their customers. The quality of service is top-notch-from the initial appointment to the final check. It's rare to find a company that's this reliable, respectful, and efficient. Highly recommend to anyone looking for trustworthy HVAC professionals.

Great local company with excellent customer service. We have had Eric service our furnace the last few years and we have been very pleased with his professionalism and timeliness.

My 30 year old boiler finally called it quits. I contacted a number of companies for estimates and I found Cromwell Energy to be the most responsive, flexible and willing to work with me. Today, their team of technicians remove the old and installed my new boiler. Once installed they took the time to go over the features. Technicians were neat and professional. Happy to be a new customer

Great service as usual from Cromwell Energy. Technicians were on time and very effecient. Highly recommend!

First time dealing with them. Annual service on a Navien Combi unit installed 2 years ago, they were great would highly recommend!

Cromwell Electric was wonderful to work with. Jeff gave a clear explanation of estimate for mini split a/c and installation happened within a few weeks (earlier than expected)! Tom, Jason and Ken were extremely professional and friendly. Got work done in a day without interrupting us in the home. Everything was cleaned up and took time showing us how to work the units and care for them. We will continue to use this company for multiple services when needed. A+++.

Eric Mori came to do my annual service and he was exceptional! He took the time to answer all my questions, thorough and polite ! I was so pleased and he was neat and timely! He did both my AC and heating!

In the middle of a heat wave, our AC quit. Having used Cromwell Energy for furnace maintenance previously, I recalled the excellent service they provided. They did not disappoint again. Even though they were scheduling a week out, a technician became available the next day. Eric was professional, courteous, answered all my questions (and then some), and clearly was an expert in his field. Thanks to Eric and the excellent office staff, our AC stands ready for the next heat wave! Highly recommend Cromwell Energy!!

Cromwell Energy has always given us excellent service and we highly recommend them!

I have used Cromwell Energy for more than 15 years. Eric performed the annual tune-up of my furnace and central A/C. He does a great job of explaining what is being done, was prompt, professional, and experienced. Highly recommend!

Great service today on my air conditioner from Eric! He knows his stuff 🙂

We called Cromwell Energy for a recent AC issue because they promptly fixed an issue we had a cpl years ago. Rep Eric came to our home, quickly identified the issue and had the AC running in no time. He was obviously very knowledgeable as well as courteous and thorough! Once the AC was on he verified the issue was resolved completely before leaving. Cromwell Energy was reasonably priced, will definitely call them again!

Central A/C wasn't working when I needed it. Cromwell Energy sent Eric over the same day. They called before he came and he came when he was supposed to. He was very professional and methodic in tracking down and resolving the issue. I have been a custom for years and the service is always excellent.

Great service, extremely professional, very responsive to heating and cooling needs! My review is based on many years relying on Cromwell Emergy’s services.

Have used Cromwell Energy for several years and always happy with their work. Eric performed the annual service on my HVAC today, very pleasant and knowledgeable technician.

We have been a customer for many years and are always extremely satisfied with the service. Eric was out today to check our air conditioner unit. He was very knowledgeable, courteous and professional. We would recommend Cromwell Energy and we are grateful for the great service with Eric!

I recently encountered a problem with my A/C unit, and Cromwell Energy promptly sent a technician. He conducted himself professionally, clearly explaining the problems and available repair options. Before the technician was dispatched, I had the opportunity to speak with a service manager which is impossible for some companies. So big shout out to their technician Keith, great job.

I have been a customer of Cromwell Energy for many years. They are an OUTSTANDING Company with an Excellent staff. Eric has been servicing my system for the past few years and I have found him to be VERY Professional, Knowledgeable, Helpful and friendly. What more could a costumer ask for?

First time using their service, and I am more than pleased with them. AC unit was leaking and not cooling. Called them, and they quickly scheduled me for a visit. David quickly identified the issue and fixed it on the spot. Truly recommend them.

I have been happy using Cromwell Energy for 40 years. Just wanted to comment on my experience with Eric. He has been here the last few times I needed help with my furnace and AC. He is so friendly to work with, always explaining any issues and what he did to resolve problems. In the past dealing with Brian has also been very helpful. Kim Z., Cromwell

We have been using Cromwell Energy for years and years. I can't say enough about the quality of their service--this company is amazing. They have cared for our boilers (we live in an own a 2-family) and installed a very complex, energy-efficient HVAC during a process that required multiple trips to our tiny attic and cellar. Throughout every visit, whether for installation or annual service calls, the technicians not only show great expertise, but are friendly and kind. And the office staff (thank you, Ronnie!) are exceptional, too. Thank you, Cromwell Energy! We feel lucky to be one of your customers.

Always prompt and excellent service from Cromwell Energy. Employees knowledgeable, polite and helpful. David is great and Ronnie, the secretary, is a pleasure! Lou carries on the family tradition.

Service and staff are top notch. They have exceed my expectations when it comes to customer service. Staff is super friendly, professional, and care about their customers. I would highly recommend.
