Hillside Heating & Air Conditioning

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.
