Customer Service is Job #1 at Cromwell Energy!
Cromwell Energy is not the biggest company in the area, but we do know our customers by name not by a number. Our bottom line is all about making sure the customer is satisfied, not about short-term profits and impersonal business-only relationships. We actually like our work and love keeping our customers happy.
Right from the start of Cromwell Energy, Bud Spada and Tom Allessio made the decision to put you, the customer first. They knew that by creating satisfied customers, they could build a solid reputation and grow the business. Word of mouth and repeat customers has “fueled” that growth now for over 35 years!

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 🙂
