Alonso Advanced Air

Alonso Advanced Air operates out of Hesperia in San Bernardino County and carries CSLB license #1091945, classification C20 — Warm-Air Heating, Ventilating and Air-Conditioning. 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 High Desert: Winter freeze cycles are a genuine factor above the Cajon Pass in a way they are not down in the valley, and work specified for Los Angeles does not always survive up here.

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 #1091945 is current, and check bond and workers’ compensation coverage, using the CSLB license lookup before signing a contract or paying a deposit.
