"Ariel has serviced and maintained my AC for awhile now and recently replaced my ancient metal ducts with new ducts and vents. He is the best! Reliable, honest, hard working, efficient, neat and well organized, exceptional work ethic, a master craftsman. He is a joy to work with and I highly, highly recommend him. You couldn't be in better hands when you work with him. Forget 5 stars ---- he is at least 10 stars!!!!"

"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.
