Covering commercial refrigeration and residential HVAC repair from Santee's Magnolia Avenue, All Temp Refrigeration Air Conditioning and Heating operates out of Suite 146 at 8733 Magnolia Avenue in the Prospect Avenue industrial corridor. The commercial refrigeration scope serves restaurant walk-in coolers, reach-in display cases, and ice-machine systems that complement the residential heating and cooling work performed by nearby contractors such as Straight Shooter Heating & Cooling on Mission Gorge Road. Service calls on the residential side address split-system AC repair, furnace troubleshooting, and heat-pump diagnostics. Energy-efficiency upgrades that pair HVAC replacement with window improvements are coordinated alongside glazing specialists including Budget Windows on Mission Gorge Road to reduce thermal load before new equipment is sized. Walk-in cooler installations require dedicated 208/230-volt circuits, refrigerant line sets rated to the specific compressor tonnage, and digital temperature controllers calibrated to maintain product-safe holding ranges within one degree of setpoint.
