Should Richmond Hill switch to a heat pump?
A heat pump earns back its extra cost in Richmond Hill within a sensible timeframe. $1,000 is what Richmond Hill 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. Richmond Hill's residents would see roughly $294 a year back in running costs, putting the payback around 3.4 years. The window here is reasonable, and it's specific to what Richmond Hill actually pays for power and gas.
Richmond Hill's weather, in the numbers that matter
Degree days tell the story here: Richmond Hill racks up 1252 heating degree days each year (base 65°F), and summers are severe enough that cooling can dominate the annual bill, with 2806 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 26.4°F here (record low 24.6°F), which works out to a seasonal COP of 2.99 for the standard class of unit this climate calls for. Richmond Hill's winters don't get cold enough to need the cold-climate premium — a standard unit holds up fine. These numbers come from HUNTER ARMY AIRFIELD, the closest NOAA station, 13.1 miles out.
Richmond Hill's running-cost comparison, in dollars
Modelled on a typical 2000-square-foot house, the heat pump draws about 1,060 kWh a year to keep it warm, plus cooling, for a combined electric bill near $514 a year. That compares with roughly 13 Mcf a year of gas at Richmond Hill's 20.42 per-Mcf rate — about $808 a year — against a local electricity rate of 14.90¢/kWh. Buy it outright, not incrementally, and payback stretches to 37.5 years; over 15 years the net position sits $3,405 ahead.
Electric resistance heat in Richmond Hill, compared
Gas isn't universal in Richmond Hill — 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. The saving here runs about $500 a year, which recovers the extra $5,500 spent going electric in roughly 11 years.
How Richmond Hill compares nationally
Ranked against the other 3206 cities covered, Richmond Hill comes in at 2782 for heating severity — 1 would be the coldest place in the dataset — and 1940 by population, where 1 is largest. That's the mildest third of cities covered, where utility rates carry more of the answer than climate does.
What to do with this number in Richmond Hill
