Heat pump vs. gas furnace in Hollister, CA

Here in Hollister, the honest answer is that a heat pump raises your annual running cost. Against a like-for-like gas furnace and AC swap, going electric costs $1,000 more up front here (already netting out a $2,000 tax credit). The heat pump would cost about $32 more a year to run than the furnace it replaces — a premium with no payback. That's Hollister's own climate and rates talking, not a hedge or a caveat.

Hollister's weather, in the numbers that matter

2815 heating degree days pile up here every year, so Hollister has a mild winter by US standards; the cooling side runs to 454 cooling degree days, where summers add a moderate cooling load. Sizing runs off the design temperature, not the average day: 32°F here (record low 30.2°F), which works out to a seasonal COP of 3.15 for the standard class of unit this climate calls for. Hollister's winters don't get cold enough to need the cold-climate premium — a standard unit holds up fine. These numbers come from HOLLISTER MUNICIPAL AIRPORT, the closest NOAA station, 3.2 miles out.

Hollister's running-cost comparison, in dollars

A 2000-square-foot house here would pull roughly 2,263 heating kilowatt-hours annually on top of cooling, totalling about $870 a year on electricity. The gas furnace it replaces burns roughly 29 Mcf a year at 22.01 per Mcf here, for a running cost near $838 a year (electricity here runs 32.83¢/kWh). Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs past the 15-year equipment life, for a 15-year net position $1,473 behind.

Electric resistance heat in Hollister, compared

Gas isn't universal in Hollister — many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Hollister's answer improves. The saving here runs about $1,663 a year, which recovers the extra $5,500 spent going electric in roughly 3.3 years.

How Hollister compares nationally

Hollister lands at position 1987 out of 3206 cities on heating severity (coldest is 1), and 914 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.

Where Hollister's figure comes from

Every constant behind this page — the 3.15 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Hollister is one of the cities where running costs land higher every year, not just slower to pay back — the guide to where this happens lays out why.
