Riverside Plumbing Company operates out of Corona in Riverside County and carries CSLB license #1082213, classification C20 — Warm-Air Heating, Ventilating and Air-Conditioning, C36 Plumbing. License status at the time of compiling this listing: active, with no suspension recorded.
HVAC contractors carry the C-20 classification, which covers equipment replacement, duct systems, and the airflow and combustion venting that make them work safely.
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 whether the duct system is being tested. California’s Title 24 energy code requires duct leakage testing on many change-outs, and leaky ducts waste a large share of what the equipment produces.
License status can change at any time. Confirm license #1082213 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
