Hot Water Heaters

We install and service oil, gas and electric hot water heaters, using the finest brands like Heat Flow, AO Smith and Navien.

From new water heater installations to annual maintenance and repair, our technicians are well-versed in all brands and models.

Water Heater Installation Services

Older model Hot Water Heaters can account for up to 15% of a home’s total energy cost. If your current hot water heater is not delivering hot water the way your family would like, it may be time to consider a new, modern Hot Water Heater, like a high-efficiency tankless model. Many times the newer models and technology available today in Hot Water Heaters can deliver higher capacity at twice the efficiency of a standard older model. We install oil, gas and electric hot water heaters, using the finest brands like Heat-flo, AO Smith and Navien. Hot Water Heater tanks are extremely well insulated today, with very little loss of heat, resulting in lower oil, electric or gas bills for you.

    Water Heater Maintenance & Repair Services

    If you need repairs or service to your existing hot water heater, our technicians are well-versed in all brands and models, and can provide a quick response to help our customers when they are without hot water. Maybe you are having problems with your hot water demand outpacing the capacity of the hot water system in place now. We are happy to look at your needs and provide a written estimate that thoroughly covers any work, parts, or hot water heater replacements that may be called for. Choose from the best brands, like Heat-flo, AO Smith and Navien.

      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!!

      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.
