California Title 24 โ€” What Homeowners Need to Know

California's 2025 Energy Code (Title 24) updated HVAC efficiency requirements effective January 1, 2026. ECO Heating & Cooling ensures every installation is fully compliant, properly permitted, and inspected.

Title 24 โ€” The 2026 California Energy Code Update

California's Building Energy Efficiency Standards (Title 24) are updated every three years. The 2025 standards, effective January 1, 2026, include several important changes relevant to HVAC installations and replacements.

Key Title 24 Changes Affecting HVAC

  • Updated efficiency minimums for all HVAC equipment types
  • Encourages heat pumps through updated energy budget calculations
  • Requires electric-ready infrastructure in new multifamily buildings
  • Mandates heat pump or high-efficiency replacements for certain commercial RTU alterations
  • Updated HVAC controls requirements for zoning and smart thermostat compatibility

What This Means for Homeowners Replacing HVAC

When you replace your HVAC system, the new equipment must meet current Title 24 standards โ€” not the standards that were in place when your old system was installed. This is one reason why it's critical to work with a licensed, experienced contractor who stays current on code requirements.

ECO's approach: Every ECO installation includes permit filing with the local building department and a final inspection. We don't do "unpermitted" HVAC work โ€” it creates liability for you and voids manufacturer warranties. Title 24 compliance is built into our process, not an add-on.
