So far not so good. My service call got rescheduled 2 times and my AC isn't working as it should to begin with and they wanted to reschedule me after Memorial Day. They offer no compensation at all especially if I am purposely missing work because of this twice already. Now a third time. Again, so far, not so good service at all. We will see what happens on the third go around.

We have been using Elm for almost 10 years and they have always been responsive, prompt and reliable but we just had our annual service and Boris our technician was terrific. He is by far the best technician we have ever had. He took the time to explain what was necessary. We have a filter that is not standard size and Elm has not been able to provide us with the special measurement filter so we have made do with the filter we are given. Boris measured it to attempt to attain the proper size to potentially order the special size and even showed us how to tape the current filter in place so it could work properly. After all these years a simple trick of taping the filter in place solved the problem. We couldn't be happier with the service we just had.

We had a ductless unit installed in the lower level of our home yesterday. The two gentleman who did it were Moses and Andres. They were polite, efficient and fully explained how to use the system and how to maintain it. We were very pleased with their service. Have already recommended this company to others. Sincerely Jo-Tina and Joseph DiGennaro

I had a new a/c system installed to replace the a/c system that Elm A/C installed 22 years ago. Everything from the initial call for an estimate to the completed job went smoothly with no problems. I'm looking forward to the coming Summer season to see how much better my new A/C system is going to be. Thanks to everyone at Elm Air Conditioning for a job well done! Regards, Don Blixt
