What do our customers have to say?

"Outside A/C was not starting"

We had several power hits on Sunday and when the power stabalized, our outside A/C unit would not start. I called 2 or 3 service companies and left messages as they were closed on Sunday. I got a call back from Orange County Mechanical on Sunday evening and the tech apologized for not being able to get to us that night as he had some more calls to make but could stop by in the morning. The tech showed up at 7:20am on Monday and we had A/C by 8:00am. He had to replace the capacitor in the unit. The service call and parts charges were very reasonable. I will definitely use this company again.

-Randy, Chester NY

"Replace central A/C unit and recharge other unit"

Were quick to respond and honest. They did the work that they promised. Reasonably priced and the quality of work was excellent.

-Jose, Newburg NY

"Needed a new air conditioner unit"

I needed a new air conditioner unit and a year later I needed a new hot water heater replaced. He also comes by twice a year for maintenance and everything runs great. It actually went fantastic. Ed was able to get me a warrantee that I did not even know that I had on both repairs.

-Mike, Congers NY

"Hot water heater"

Ed was completely knowledgeable about the work being performed. He explained everything to us. He was clean, on time and professional. We use him for all our AC/Heating issues.

-Todd, Congers NY

"Full inspection, renovation and new install"

I could not have imagined this Job going any better, seriously. I was previously quoted almost triple and that the job would take twice as long as it did. Ed was a true professional and down to earth. I don't know much about this kind of work so he took the time to walk me through everything. Most importantly, however, his craftsmanship was phenomenal, which was translated to the immaculate heating of my home. It's warm faster and I am even saving money as it's more efficient. I would wholeheartedly recommend Ed and his services to anyone, no qualms about it.

-Paul, Sullivan County NY

"I had a flood in my basement"

I had a flood in my basement due to my sump breaking down. He cleaned up everything carefully. I was very pleased.
