How do San Diego homeowners pick a licensed Heat Pump Installation contractor — quick, city-specific answers
- Can I replace my gas furnace with a heat pump?
- Yes — a heat pump both heats and cools, so it can fully replace a gas furnace. In colder areas a dual-fuel setup keeps the furnace as backup for the coldest days. Either way, insist on a Manual J load calculation; conversions can need duct resizing or an electrical upgrade.
- When is replacing an old heat pump better than repairing it?
- If it's past 12–15 years, still uses phased-out R-410A refrigerant, needs a compressor, or the repair bill approaches a third of replacement cost, replacing usually wins. A reputable contractor compares both paths before recommending.
- 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.
- How should homeowners vet electricians and panel upgrades tied to heat pump installations in San Diego?
- Verify that electrical work is performed by licensed contractors and noted in the scope. Ask for the electrician's CSLB information and whether they size panels for future loads. Confirm that proposed electrical upgrades are included in permit filings and that the contractor documents inspection signoffs.
- 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.
