The short answer
In Temple City a heat pump should be sized primarily for long, hot summers, since winters are mild and heating loads are small. We evaluate ducts, electrical capacity and placement, explain current incentive facts, and install and commission the system in both modes.
A heat pump does two jobs with one outdoor unit: it pulls heat out of your home in summer and brings heat in during winter. In Temple City, about five miles southeast of our Pasadena shop, cooling is the bigger of those jobs by far, and that shapes how we design a heat pump system for a house in 91780. Get the cooling side right for a hot inland summer, and the mild winter heating takes care of itself. Here is how we approach the decision, the design and the installation.
Heat pump versus AC plus furnace
Mechanically, a heat pump is an air conditioner with a reversing valve, so its cooling performance is comparable to a modern AC of the same efficiency. The difference is heating. Instead of burning gas, it moves heat from outdoor air into the house using electricity. Because winters in the Los Angeles area are mild, the heat pump operates in its most efficient range for nearly all of the heating season.
For many Temple City homeowners, the timing question decides it. If both the AC and the furnace are aging, replacing them together with one heat pump system is often simpler than buying a new condenser and a new furnace. If the furnace is fairly new and only the AC has failed, a dual-fuel setup, where the heat pump handles most heating and the furnace covers the rare cold morning, is another route.
Design priorities for a hot valley home
Our design work focuses on the things that matter most in a long cooling season.
- Accurate load calculation based on the house itself, including windows, insulation, shading and room layout.
- Variable-speed equipment where the budget allows, for steady temperatures and lower noise during long run times.
- Duct systems that are sealed and well insulated, since attic temperatures in summer can be extreme.
- Return air paths large enough to move the airflow a heat pump requires.
- Thermostat setup that limits backup electric heat to the times it is truly needed.
What the site visit covers
Before we quote, we look at your electrical panel to confirm it can carry the new circuit, especially if gas heat is being retired. We inspect the attic ducts and the furnace location to see whether an air handler will fit where the furnace was. Outside, we choose a spot for the heat pump with clearance on all sides, a level base, and a path for defrost water to drain away from the slab and walkways. On many Temple City lots, the side yard is the natural spot, and we keep the unit away from bedroom windows where possible.
If part of the house was added later, or a garage has been converted to living space, we may suggest a ductless head for that area rather than stretching the main ductwork.
Incentives, stated accurately
Incentive programs change frequently, so we stick to verified facts. The federal Energy Efficient Home Improvement Credit applied to qualifying heat pumps placed in service before December 31, 2025, and it is no longer available for new installations after that date.
LADWP offers heat pump rebates to its residential electric customers, but Temple City is outside the City of Los Angeles, and many homes outside the city are served by Southern California Edison instead. Available rebates depend on the utility that serves your address. We confirm the current offer for your home before we include anything in a quote.
Installation day and beyond
With the permit in hand, the crew removes the old equipment, sets the outdoor unit and indoor air handler or ductless heads, installs and pressure-tests the refrigerant lines, and wires the circuit. After evacuating the lines and releasing the charge, we test cooling and heating, measure airflow and temperature change, and confirm defrost operation. You will get a walkthrough of the thermostat, filter changes and what defrost looks like on a cold morning. After that, a yearly maintenance visit keeps coils clean and the system running efficiently through Temple City's long summers. We also install heat pumps in San Gabriel, Arcadia, El Monte, Rosemead and San Marino.
