We have had their service on more than one occasion, the always show up when they say they are going to. We were extremely happy when they were able to install our AC , no other businesses would even come and give us a quote.

I chose E.C based on the reviews. So I want to thank those before me for being honest. The service was great. I removed the fan on my air conditioner because themotor was so hot. When the tech came he could of made a comment, but he just put it back in and fixed what was wrong. Took more time to put the fan back then it didto fix the issue.

A/C went out this last hot stretch. Brian came out within a half hour of me calling. They sure did not need to attempt to fix the inefficient dinosaur that is my a/c unit, but knowing the forecast they did! Meanwhile, they patiently explained all my options for new. Pleasure to work with all of E.C. Merril; Brian he is a hard worker (outside when it's 90!), courteous, patient, cleans up after the work is done and makes sure I know what's going on.
