"My experience could not have been better, every time I needed Ariel. More than once my medical practice has had air conditioning problems and he has done everything he could resolve the situation as fast as possible. The same has happened at my home. I have the utmost respect for him and his business. He is efficient, very responsive and his price is very fair. He has never disappointed and I think anyone can expect the same outcome!!"

"We've had two visits by Core Mechanical.
One for diagnosis and customer approved temporary repair to allow time to acquire a replacement unit.
Second for replacement of faulty a/c unit.
Both occasions the service tech telephoned with expected arrival, and an updated weather delay.
Services performed quickly and with no difficulties.
Costs were as quoted.
We were happy to provide a gratuity beyond the quoted price.
We would not hesitate to recommend Core Mechanical to anyone needing their services.

"I was not sure what was wrong so I called these guys, described what I knew, and they said they would come look at it. They said there was an $85 minimum charge for an assessment but that it would be credited toward any kind of services and equipment that I needed. They showed up within 2 hours and even called me ahead of time to double check that I would be there. Once they arrived they checked several things before opening up the unit and then showed me where the electrical part of the system had melted, likely due to a power surge. So it had to be replaced, but they said they could replace the whole system (inside, outside and thermostat) that day. They even got a crane because the outdoor unit is on the roof of my condo unit. The techs were all quick, polite and respectful. They also helped provide photos and documentation should we need to submit a claim to the homeowners insurance company. I would highly recommend them and would use them again in a heartbeat. Big thanks to Alex Rodriguez and his team."
