A heat pump replaces your AC and your furnace with one system, moving heat instead of burning fuel to make it, and works well whether it is going into a Craftsman that has never had ductwork or a postwar home ready for a straightforward swap. We size every Pasadena heat pump with a real load calculation and back the installation with a written warranty.
A heat pump is not a different kind of AC. It is one system that both cools and heats your home by moving heat instead of burning fuel to create it. Here is what makes it worth considering for a Pasadena property.
Many Craftsman and early-1900s homes near the Arroyo Seco were never built with ductwork at all. A ductless heat pump zone adds both heating and cooling without a disruptive retrofit through original plaster and woodwork.
If your AC and furnace are both approaching the end of their life around the same time, replacing both with one heat pump is often more cost effective than replacing each separately.
Because a heat pump moves existing heat rather than generating it from fuel, it can run at 300 to 500 percent efficiency, far above a gas furnace's maximum of around 98 percent, which matters given how hard systems run here during a mountain-blocked heat wave.
Heat pumps often qualify for utility and manufacturer rebates that a standard AC or furnace replacement does not, given their role in reducing overall energy use.
Research and lab spaces near Caltech and JPL often need tighter, more consistent temperature control than a typical office, and a properly sized heat pump delivers that from one system.
Modern inverter-driven heat pumps run at variable speeds rather than cycling fully on and off, which typically means quieter operation and steadier indoor temperatures.
Heat pump performance is rated two ways, not one. SEER2 measures cooling efficiency, the same rating used on a standard AC, while HSPF2 measures heating efficiency, a number a straight AC system does not have at all. Standard heat pumps start losing heating capacity as outdoor temperatures drop below the mid-20s, and Pasadena's winters stay comfortably within the range where a properly sized heat pump performs at full efficiency without needing backup heat.
Summer sizing matters just as much here. The San Gabriel Mountains block the marine layer that cools much of the rest of Los Angeles, pushing summer highs into the high 80s to low 90s with a record of 113 degrees, so we size for both extremes rather than a coastal LA average. Whether the property is a century-old Craftsman needing a ductless zone or a postwar home with existing ducts, we size every Pasadena heat pump installation for both the SEER2 and HSPF2 numbers together, accounting for the home's actual construction, not just its square footage.
We run a Manual J calculation for both cooling and heating demand, since a heat pump has to be sized correctly for both seasons, not just summer.
You get a clear, itemized quote showing both efficiency ratings and total cost, so you know exactly what you are buying before anything is ordered.
Old equipment is removed, new line sets are brazed, and the heat pump is installed to manufacturer and code specifications, typically in a single day.
We verify refrigerant charge, test both heating and cooling modes, and walk you through the new thermostat and its heat pump settings before we leave.
Final pricing depends on tonnage, SEER2 and HSPF2 ratings, and your home's existing ductwork. These are typical ranges for a full heat pump installation in Pasadena.
| System Type | Typical Range |
|---|---|
| 2 to 2.5 ton, standard efficiency | $7,000 – $10,500 |
| 3 to 3.5 ton, standard efficiency | $8,500 – $12,500 |
| 4 to 5 ton, standard efficiency | $10,500 – $15,000 |
| High-efficiency upgrade (18+ SEER2 / 9+ HSPF2) | Add $2,000 – $5,000 |
| Ductless mini-split system (per zone) | $3,500 – $6,500 |
