The short answer
A heat pump can replace both your air conditioner and gas furnace in San Gabriel, and it should be sized for the area's hot inland summers. Rebates depend on whether LADWP or Southern California Edison serves your address, and the federal 25C tax credit no longer applies to new installations.
If you're thinking about replacing an aging air conditioner or gas furnace in San Gabriel, a heat pump can handle both jobs with one system. AllPro HVAC Services installs ducted and ductless heat pumps for homes in the 91776 ZIP code, about 7 miles east of our Los Angeles base. This page covers what matters locally: how inland summer heat affects sizing, what regional furnace rules mean for your choice, and how to figure out which rebates apply to your address before you buy.
Sizing a Heat Pump for San Gabriel's Climate
Los Angeles has a Mediterranean climate with dry summers and mild winters, but conditions vary a lot across the region. San Gabriel sits inland in the San Gabriel Valley, and inland areas run much hotter in summer than neighborhoods near the coast. That means the cooling side of a heat pump does most of the work here. The system should be sized for long, hot stretches, not just the occasional cool night.
Fall Santa Ana winds can also bring hot, dry spells after many people assume summer is over. A properly sized heat pump keeps up during those periods without running nonstop. In winter, the same equipment reverses to provide heat, and mild nights are well within what modern heat pumps handle efficiently.
Replacing a Gas Furnace With a Heat Pump
Many homes heat with a natural-gas forced-air furnace. South Coast AQMD Rule 1111 limits NOx emissions from natural-gas fan-type central furnaces sold and installed in our region, and the air district has been amending the rule toward zero-emission requirements. The district sets and revises the compliance dates. If your furnace is near the end of its life, check the current rule before you decide what to replace it with.
A heat pump is one way to replace a furnace and an air conditioner at the same time while moving away from gas heat. We'll walk through the options with you, including whether your existing ductwork can be reused.
Rebates Depend on Who Serves Your Address
Which equipment rebates are available depends on the electric utility that serves your home. San Gabriel is outside the City of Los Angeles, and many homes outside the city are served by Southern California Edison rather than LADWP. Your electric bill will tell you which one serves you.
If your address is an LADWP residential electric account, the Consumer Rebate Program offers rebates on qualifying heat pump HVAC systems. The amount is based on the unit's SEER2 and HSPF2 ratings. You apply after the equipment is purchased and installed, within 12 months of purchase, so keep your paperwork. Whatever your utility, we confirm the current offer before including it in a quote.
One change to know about: the federal Energy Efficient Home Improvement Credit (25C) covered qualifying heat pumps placed in service before December 31, 2025. It is not available for new installations after that date, so don't count on it when planning a project now.
Ducted or Ductless: Choosing the Right System
If your home already has ducts in decent condition, a ducted heat pump can often replace the existing furnace and outdoor AC unit. We inspect the ducts for leaks, sizing problems and damage first. A new system connected to leaky ductwork won't deliver the comfort or efficiency it should.
Homes without ducts, room additions and converted garages are often better served by ductless mini-split heat pumps. These mount indoor units on walls or ceilings and connect to an outdoor unit through a small line set. Some homes use a mix of both.
What Installation Involves
A typical heat pump installation follows these steps:
- A load calculation based on your home's size, insulation, windows and sun exposure, not just the size of the old unit
- A duct inspection, plus any needed sealing or repairs
- A check of your electrical panel, since a heat pump replacing a gas furnace may need added electrical capacity or a dedicated circuit
- Removal of old equipment and placement of the new outdoor unit on a level pad
- Permits and inspection as required by the city
- Startup, refrigerant charge verification and airflow testing
- A walkthrough of the thermostat and filter maintenance
