Hot inland summers strain air conditioners, coastal fog and cool nights make heating and humidity control matter, and dry seasons can stress every component. Grayarea HVAC LLC serves residential and commercial customers across California, bringing a focused approach to keeping indoor air comfortable through all of these conditions.

What the license covers
C-20Warm-Air Heating, Ventilating and Air-Conditioning
California is in the DOE Southwest region: new central air conditioners installed since January 1, 2023 must meet at least 14.3 SEER2 and 11.7 EER2 (13.8 SEER2 and 11.2 EER2 for systems 45,000 BTU/h and larger). Heat pumps must meet 14.3 SEER2 and 7.5 HSPF2 nationwide.
Since 2025, new systems are built for lower-impact refrigerants such as R-454B or R-32. Ask which refrigerant a quoted system uses and for its AHRI certificate number, which confirms the matched system’s rated efficiency.
CSLB lists #1084528 as active (record dated Aug 4, 2026). Licensed since 2021. Re-check it yourself before work starts — it is free and takes a minute.

Ask for proof of insurance
We have no insurance details on file. Ask for a certificate of general liability and workers' compensation coverage before anyone works in your home.
Ask who pulls the permit
Replacing an AC, furnace, heat pump or water heater usually needs a local permit and inspection. A licensed contractor normally pulls it — ask that the permit is included in the written quote.
Ask for local references
We do not have review data for this business yet. Ask for two or three recent customers near you.
California homeowner protection
California law caps the down payment on a home improvement contract at 10% of the contract price or $1,000, whichever is less. Never pay more up front.
