What Davis's homes mean for your air conditioning repair
With a median build year of 1983, the typical home in Davis is middle-aged, about 43 years old. Systems installed before 2010 may still run on R-22, and later ones generally use R-410A. Both can be repaired, but the EPA notes R-22 now comes only from recycled or stockpiled supply, and a complete new system today generally must use a lower-GWP refrigerant such as R-454B or R-32.
About Davis
Davis runs a Resale Program: residential properties must go through either a city resale inspection or self-certification before a sale, with 1-, 2- and 3-unit properties subject to the inspection process, to confirm minimum building, health and fire-safety standards.

Local rules, utilities and conditions in Davis
PG&E delivers natural gas in Davis, which matters if your AC shares an air handler with a gas furnace. If you ever smell gas near the furnace, leave the home right away and call 911, then PG&E at 1-800-743-5000, as PG&E advises. Where PG&E also supplies electricity, its residential rebates page does not currently list an AC or heat pump rebate, and the statewide TECH Clean California heat pump incentives were reserved as of November 14, 2025. Income-qualified households can ask about PG&E's no-cost Energy Savings Assistance program. On PG&E's E-TOU-C plan, power costs the most from 4 to 9 p.m. every day.
Replacing an AC, heat pump, or mini split in Davis requires a building permit from City of Davis Community Development and Sustainability Department. Under California's 2025 Energy Code, which covers permits filed since January 1, 2026, the ducts connected to new equipment must be sealed and tested by a third-party rater to 10% total leakage or 7% leakage to the outside, and the refrigerant charge must be verified on heat pumps and on air conditioners in most inland climate zones. Your contractor normally pulls the permit. CSLB warns against any contractor who offers a lower price to skip it, because the permit is what gets the work inspected.
Davis is on the Sacramento Valley floor, where summers are long and hot. The National Weather Service explains that the Delta breeze, a sea breeze that forms at the Carquinez Strait, can push cooler marine air inland when the marine layer is deep enough. Let the AC carry the afternoon, then open windows once it's cooler outside and close them in the morning. Attic ducts bake in valley summers, so sealed, insulated ducts matter as much as the AC itself.
Flood notes for Davis
The City says FEMA's current flood hazard areas south of I-80 stop at the west levee of the Yolo Bypass; FEMA's flood layer maps roughly 8% of the city as Special Flood Hazard Area.
Renting in Davis?
About 44% of homes in Davis are owner-occupied, so many residents rent. California law requires landlords to keep rentals habitable, and the Attorney General's tenant guide lists working heating, but not air conditioning, among the basics. Senate Bill 655 (2025) made a safe maximum indoor temperature state policy but did not create a statewide AC requirement for existing rentals. If your unit came with AC, check your lease for who handles repairs, report problems to your landlord in writing, and keep copies. Get written permission before hiring your own technician for a landlord's system.
