Customer Testimonials
At Cromwell Energy, customer satisfaction is always our highest priority. Read some of our many 5 star reviews!
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.
