Mark is a highly professional and knowledgeable HVAC contractor. He is very customer oriented and strives for customer satisfaction. I highly recommend his services. Some details below, if you have time to read!
AC service: We had Mark Shasho install 3 Fujitsu ductless AC units in our son's apartment in Brooklyn. Mark is very detail oriented. His estimate included a lot of details (unlike other estimates I received) regarding the piping, communication wires, pumps and their warranties, in addition to standard information re. capacity and warranty about outdoor condenser and indoor wall units. He worked closely with my architect and electrician to get the required city permits. (It is important to know that ductless units require not only mechanical permit, a separate electrical permit.)
Although the ductless units were installed last year, because of other builder-related issues (totally unrelated to Mark's work), we could not use the AC units last summer. They were taped shut for almost a year. When we started the units this year, it was shooting debris and water. We contacted Mark again. He readily cleaned off all construction debris and power washed them. He did not charge any extra fee since he understood that we never enjoyed the units. I call that excellent service.
Heating service: Our home is a historic house and came with an old gas furnace. We had heating issues and I called Mark’s service (and other HVAC companies for estimates). Mark (and his worker) found issues with the heating pump and expansion chamber. He recommended that we replace them and add new thermostats and new control unit to isolate the 2 family units. Mark also said that the furnace we have, although old, is a good system. This advice helped/worked out cheaper compared to other HVAC guys who recommended that we put in new furnace, and new “everything” which would have been very expensive.
(Text him with the nature of the urgency, if phone call is not answered or your call is not returned immediately. He is usually a busy guy because of his reputation and repeat customer work.)
