The short answer
A heat pump replaces a separate air conditioner and gas furnace with one electric system, which suits South Pasadena's hot summers and mild winters. AllPro HVAC Services sizes each system to the house, checks your ducts and electrical panel, and confirms which utility rebates apply to your address before quoting them.
A heat pump heats and cools your home with one system. Instead of burning gas to make heat, it moves heat: indoors in winter, outdoors in summer. In South Pasadena, that means one piece of equipment can handle warm inland summers and cool winter nights. AllPro HVAC Services installs heat pumps in homes throughout ZIP code 91030, about 4 miles east of our Los Angeles base. This page covers how we size and install a system for your house, what to check before you replace a gas furnace, and how rebates work for a South Pasadena address.
Why a Heat Pump Fits South Pasadena Homes
Los Angeles has a Mediterranean climate with dry summers and mild winters. South Pasadena sits inland from the coast, so summer afternoons run much hotter here than in beach neighborhoods. Fall Santa Ana winds can also bring hot, dry spells. Cooling capacity matters at least as much as heating.
Winters are mild, so a properly sized heat pump handles winter heating comfortably. For many homeowners, the appeal is simple: one system, one set of maintenance visits, and one thermostat for the whole year.
- One electric system for both heating and cooling
- No combustion inside the home for heating
- Can often connect to existing ductwork
- Ductless options for homes or additions without ducts
- Variable-speed models that run quietly and hold steady temperatures
How We Size and Plan Your System
We don't size a new heat pump by copying the label on your old equipment. We run a load calculation based on your home's square footage, insulation, windows, sun exposure, and ceiling heights. An oversized unit cycles on and off too often and leaves rooms clammy. An undersized one struggles on the hottest afternoons.
Next we look at your ducts. If your home is older, the ductwork may be leaky, undersized, or poorly insulated. We tell you what we find and whether repairs or sealing make sense before the new system goes in. If your home has no ducts, or a room the central system never reaches well, a ductless mini-split can serve those spaces directly.
Finally, we check your electrical panel. A heat pump usually needs a dedicated circuit. If your panel doesn't have the capacity, we explain that up front so it's part of the plan, not a surprise on installation day.
Replacing a Gas Furnace: Local Rules to Know
South Coast AQMD Rule 1111 limits nitrogen oxide emissions from natural-gas fan-type central furnaces sold and installed in the Los Angeles region. The district has been amending the rule toward zero-emission requirements, and it sets and revises the compliance dates itself.
If you're planning to replace a gas furnace, check the current version of the rule before you decide. For many South Pasadena homeowners, switching to a heat pump is a practical way to replace an aging furnace and air conditioner at the same time. We'll walk through both options with you.
Rebates and Tax Credits for a South Pasadena Address
South Pasadena is its own city, outside the City of Los Angeles. Equipment rebates depend on which utility serves your address. Many homes outside the City of Los Angeles are served by Southern California Edison rather than LADWP. We confirm the current offer for your address before we quote it.
If your home is served by LADWP, residential electric customers can apply for Consumer Rebate Program rebates on qualifying heat pump systems. The amount depends on the unit's SEER2 and HSPF2 efficiency ratings. You file the application after the equipment is purchased and installed, within 12 months of purchase, so keep your invoice and model numbers.
Note that the federal Energy Efficient Home Improvement Credit (25C) covered qualifying heat pumps placed in service before December 31, 2025. It isn't available for new installations after that date.
Installation Day and Beyond
On installation day, we protect your floors, remove the old equipment, set the outdoor unit, connect the refrigerant lines and wiring, and install the thermostat. Before we leave, we test the system in both heating and cooling modes and show you how to use the settings.
We also serve nearby Alhambra, San Marino, San Gabriel, Pasadena, and Monterey Park. If your system ever stops working on a hot night, AllPro HVAC Services offers 24/7 emergency service.
