Based in Yucaipa, San Bernardino County, Oakridge Construction & Energy holds California contractor license #975448, classified A (General Engineering, B General Building, C2 Insulation and Acoustical, C7 Low Voltage Systems, C10 Electrical, C20 Warm-Air Heating, Ventilating and Air-Conditioning, C27 Landscaping, C36 Plumbing, HAZ Hazardous Substance Removal Certification). At the time this listing was compiled, the license was active with no suspension on record.
The C-20 classification covers complete HVAC systems: heating and cooling equipment, ducting, and the controls and venting that go with them.
Working in the Inland Empire: Expansive clay soils are common across the inland valleys, and they move enough with the seasons to matter for foundations, flatwork and anything tied to them.
Before you hire any hvac or air conditioning contractor: Ask for a load calculation rather than a like-for-like swap. Oversized equipment short-cycles, costs more to run and does a worse job of controlling humidity.
License status can change at any time. Confirm license #975448 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
