Heating and cooling in Simi Valley
A furnace change-out in the same location is $117.72 under Appendix F, the mechanical fees in Simi Valley's service charges schedule effective July 1, 2025. Swapping only the A/C condenser is $98.00. Doing both at once, in the same spot, is still $117.72. Issuing the permit adds $71.05, and building inspection is billed at $197.21 an hour. Filing happens online. HVAC is on the Building & Safety Division's list of simple residential permits taken that way, and help with online submittal is at (805) 583-6723, as an April 22, 2026 copy of the city's page shows.
California law wants every home improvement contract over $500 in writing. It has to carry a Three-Day Right to Cancel notice, or five days when the buyer is a senior citizen. Don't sign without that notice. Census data put Simi Valley's median year built at 1980. By the state's maps, the city's reference point is Edison territory for power and SoCalGas territory for gas, though an address near a line can differ.
A new gas furnace there may earn SoCalGas's rebate, which runs from $1.40 to $25 per kBTUh. It has to be an ENERGY STAR model with 92% AFUE or better. A contractor holding a CSLB license has to put it in, with the permit closed. Households get one. If you suspect a leak, SoCalGas wants you out of the house first, then calling 1-800-427-2200 from somewhere safe.

Permits for heating and cooling work in Simi Valley
Under the California Mechanical Code, replacing a furnace, air handler, coil or condenser needs a building permit, and so does adding ducting, as the Contractors State License Board (CSLB) told C-20 contractors in a 2010 letter. Code details vary by city and county, so ask the building department for your address what it needs.
