If your furnace or AC is getting old, you have probably heard about heat pumps. Here is a plain-English comparison for San Fernando Valley homes, where summers are hot and winters are mild.

How they work
- Gas furnace: burns natural gas to heat air. You still need a separate air conditioner for summer.
- Heat pump: an electric system that moves heat instead of burning fuel. In summer it works like an air conditioner; in winter it runs in reverse to heat your home. One outdoor unit does both jobs.
- Dual fuel: a heat pump paired with a gas furnace that takes over on the coldest nights.
Why heat pumps fit the Valley
Heat pumps are most efficient in mild weather, and Valley winter nights rarely get truly cold. If you need a new AC anyway, a heat pump can replace both your AC and furnace with one system.
Pros and cons
- Heat pump pros: one system for heating and cooling, no gas burned inside the home, efficient in mild weather, and LADWP has offered rebates on qualifying models.
- Heat pump cons: it may need electrical upgrades, and the upfront cost can be higher than replacing a furnace alone.
- Furnace pros: a familiar technology, strong heat on cold nights, and often cheaper up front if your AC is still in good shape.
- Furnace cons: you maintain two systems, and it needs gas lines, venting and combustion safety checks.
Things to check first
- Electrical panel: older homes may need a panel upgrade for a heat pump. A contractor or electrician can check capacity.
- Ductwork: leaky or undersized ducts hurt any system. Ask about testing and sealing.
- Sizing: ask for a load calculation instead of just matching the old unit’s size.
- Permits and rebates: replacements in the City of Los Angeles generally need an LADBS permit. Check LADWP rebates before you buy.
Questions to ask a contractor
- Would a heat pump, a furnace or dual fuel be best for my home, and why?
- Does my electrical panel have room for a heat pump?
- What efficiency rating are you quoting, and what will it do to my bills?
- What do the equipment and labor warranties cover?
