Is a heat pump worth it in West Covina?
A heat pump earns back its extra cost in West Covina within a sensible timeframe. $1,000 is what West Covina would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. That premium is recovered through $323 of lower running costs every year, landing the payback clock at roughly 3.1 years. The window here is reasonable, and it's specific to what West Covina actually pays for power and gas.
West Covina's weather, in the numbers that matter
West Covina barely has a winter to speak of — 686 heating degree days a year against a 65°F base — and summers are hot enough that cooling matters as much as heating, at 2300 cooling degree days. 39.2°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 37.4°F on file. Worked through the model, that's a seasonal COP of 3.37 on the standard unit fit for this climate. West Covina's winters don't get cold enough to need the cold-climate premium — a standard unit holds up fine. Climate figures trace to the nearest NOAA station, EL MONTE AIRPORT, 7.3 miles from West Covina.
West Covina's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 515 heating kilowatt-hours annually on top of cooling, totalling about $813 a year on electricity. That compares with roughly 7 Mcf a year of gas at West Covina's 22.01 per-Mcf rate — about $1,136 a year — against a local electricity rate of 32.83¢/kWh. Looked at as a full purchase rather than an incremental one, payback here is roughly 34.1 years, leaving the 15-year total $3,842 ahead.
The other scenario: no gas furnace to begin with
Gas isn't universal in West Covina — many houses run on electric heat already. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. About $736 a year comes back this way, enough that the 7.5-year payback clears the $5,500 premium comfortably within the equipment's life.
Where West Covina ranks in this dataset
