Will a heat pump pay off in Morgan Hill, CA?
In Morgan Hill, the extra upfront cost technically comes back, just not before the equipment wears out. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $1,000 after a $2,000 federal tax credit. That premium is recovered through $10 of lower running costs every year, landing the payback clock at roughly 103.6 years. That's a technicality, not a recommendation, for anyone actually living in Morgan Hill.
Morgan Hill's weather, in the numbers that matter
2513 heating degree days pile up here every year, so Morgan Hill has a mild winter by US standards; the cooling side runs to 665 cooling degree days, where summers add a moderate cooling load. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 32°F, against a record low of 32°F. That puts the seasonal coefficient of performance at 3.15 for the recommended standard unit. Morgan Hill's winters don't get cold enough to need the cold-climate premium — a standard unit holds up fine.

What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 2,020 kWh a year to keep it warm, plus cooling, for a combined electric bill near $849 a year. That compares with roughly 26 Mcf a year of gas at Morgan Hill's 22.01 per-Mcf rate — about $859 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 1139.9 years, leaving the 15-year total $855 behind.
Electric resistance heat in Morgan Hill, compared
Not every home in Morgan Hill has gas service. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $1,523 a year, which recovers the extra $5,500 spent going electric in roughly 3.6 years.

What to do with this number in Morgan Hill
Morgan Hill, California is home to about 45,952 people, and the figures above are the same ones a local HVAC contractor uses to size and quote a system — this site doesn't guess where a real quote would land, it just tells you whether it's worth asking for one. In Morgan Hill, nothing is lost by holding off until the current equipment genuinely fails.
Ask a local HVAC contractor for a quote before committing either way.

Nothing above is a black box: the methodology guide shows the full arithmetic behind Morgan Hill's 3.15 seasonal COP and payback figure. Morgan Hill technically clears a payback on paper, just past the equipment's own working life — the no-payback guide explains why that distinction matters.
