Cromwell Energy, Inc.

Absolutely excellent company! My 25 old furnace failed just as cold weather rolled in Dec 2025 a week before holidays. Within a day Cromwell energy came in and gave an estimate. Out of 5 vendors who provided quotes Cromwell Energy was very competitive on price. Even though they were booked I pleaded to help expedite installation and to my amazement the following day Jeff managed to rearrange crew's schedule and 2 guys came in the afternoon and worked late until installation was completed. 2 guys were working non-stop that day. Superb work ethics and job was done very professionally. Later on home inspector came in and praised work that was done. For any heating/cooling future problems Energy Solutions would be contacted first.

I recently had a new furnace installed by Cromwell Energy after a friend’s recommendation, and the entire experience was flawless. Every team member—from administration and sales to the installation crew—was professional, punctual, and polite. I was especially impressed by the neatness of the installation. The technicians addressed all my questions immediately and with courtesy. I highly recommend Cromwell Energy for their top-notch service.

SHORT REVIEW: Honest, polite, punctual, reliable, and educated me on all steps for a MAJOR overhaul with a complex steam boiler replacement in an old home in Middletown, CT. They completed the job flawlessly. If they are skilled enough to do what they did at my house - they can definitely get you hooked up right. FULL STORY REVIEW (AND RATIONALE FOR WHY THEY ARE GREAT): In June 2024, My wife and I purchased my grandparent's former farmhouse in Middletown (it had not been occupied since 2008). The steam boiler was from ~2006 (but looked like it was taken off the titanic and installed on bricks in the cellar). After doing some amateur youtube research on steam boilers, I ran a couple of test runs and determined it was super sketchy/didn't seem safe running (the autofill was not working

Highly recommend Cromwell Energy. Very responsive and professional. Every tech has been a pleasure to deal with and very knowledgeable and courteous. They have previously installed and/or repaired my entire HVAC system with exceptional results. Eric came today and repaired a minor leak and the issue was explained and resolved immediately. Thank you all!

110% satisfaction guaranteed. I’ve been a customer for a long time and have had nothing but easy and pleasant transactions In addition to the great prices for products or services. I buy home heating oil from them, have repairs and service done, they even assisted me with a new oil tank and radiant heating for a new construction project. A+++ All the time. And they’re always there to help 24/7. Thank you, Cromwell Energy! -Matt Dunn
