How do San Diego homeowners pick a licensed Heat Pump Installation contractor — quick, city-specific answers
- What's the difference between a dual-fuel and a standard heat pump?
- A dual-fuel (hybrid) system pairs a heat pump with a gas or propane furnace and switches between them at a set outdoor temperature. The heat pump handles mild weather; the furnace takes over in a hard freeze — cheaper backup than electric strip heat where gas is inexpensive. One duct system, one dual-fuel thermostat.
- Does a dual-fuel system still qualify for rebates now that the tax credit ended?
- The federal 25C credit expired Dec 31, 2025. State and utility rebates remain, but eligibility varies — some electrification programs exclude systems that keep gas backup, while others allow hybrids. Confirm the specific program covers dual-fuel before you count on the money.
- Does Title 24 affect a replacement or upgrade of a heat pump in San Diego?
- Yes — Title 24 often expands scope for replacements and upgrades; expect efficiency checks and permit documentation.
- When is a dual‑fuel system a reasonable choice for a San Diego home?
- A dual‑fuel system can suit homes needing gas backup during rare cold snaps or where existing gas infrastructure is already present. Evaluate local fuel costs, home insulation, and the contractor's experience integrating gas furnaces with heat pumps. Request performance comparisons for both modes.
