Jn Construction INC

Jn Construction INC is a licensed California contractor based in Ontario, San Bernardino County, holding CSLB license #1001396 under classification A — General Engineering, B General Building, C10 Electrical, C16 Fire Protection, C20 Warm-Air Heating, Ventilating and Air-Conditioning, C36 Plumbing. 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 #1001396 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
