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.

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

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+++.

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!!
