American Innovation LLC is a licensed California contractor based in Corona, Riverside County, holding CSLB license #1103552 under classification B — General Building, C20 Warm-Air Heating, Ventilating and Air-Conditioning, C27 Landscaping, C36 Plumbing. License status at the time of compiling this listing: active, with no suspension recorded.
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: Inland Empire summers are long and hot, and Santa Ana wind events each autumn put real load on anything attached to the outside of a building.
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 #1103552 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
