D J Yonish

DJ Yonish, Inc. was established in 1969 as Furnace Repair, Inc. We have been at the same location in Bethel Park for the past 44 years servicing areas in Allegheny and Washington County. Heating and cooling have been our expertise for those years doing new construction, add-on replacement, and service work. The current owner, Don Yonish, has been in this business for 44 years, since 1975. He started out as an apprentice, working his way to an HVAC installer, then a service technician. Since 1981, he managed the company and was responsible for its complete operation.
