Walter A. Stolpp started Hillside Heating & Air Conditioning, Inc. on September 1, 1980 to fill a need he saw in the light commercial HVAC market for improved Preventative Maintenance, Service, Repair and Retro-Fit Installation in Orange County and the Inland Empire. Since that time we have expanded into the residential market and developed into a Second Generation family-run business whose primary goal remains, “Excellent Customer Service.
Hillside puts contract customers first. We do not take on commitments that would affect our ability to offer fast, honest and reliable service. We do this in two major ways. First our technicians do not work on commission and secondly we do not hire untrained personnel before summer and then lay them off during the winter. This means that all of our technicians are experienced with Hillsides ethics and procedures. In addition to our field employees our office personnel offer excellent record keeping, immediate response time and unparalleled organization. Try us out and see what you have been missing.
