Buying a new AC or heat pump in California

  • 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.

  • 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.
