Should Leesburg switch to a heat pump?
This one's marginal in Leesburg: it only clears if you stay long enough. Against a like-for-like gas furnace and AC swap, going electric costs $3,500 more up front here (already netting out a $2,000 tax credit). That premium is recovered through $251 of lower running costs every year, landing the payback clock at roughly 13.9 years. It's a genuine toss-up here — Leesburg's numbers don't point clearly either way.
Leesburg's weather, in the numbers that matter
3856 heating degree days pile up here every year, so Leesburg has a real but manageable winter; the cooling side runs to 1391 cooling degree days, where summers are hot enough that cooling matters as much as heating. Sizing runs off the design temperature, not the average day: 15.8°F here (record low 10.4°F), which works out to a seasonal COP of 3.08 for the cold-climate class of unit this climate calls for. Leesburg needs the cold-climate class of unit: past a 25°F design temperature a standard heat pump falls back on resistance backup often enough to eat the savings.

What it actually costs to run, year to year
Electricity use for heating alone comes out to about 3,170 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $722 a year. Leesburg's gas rate of 16.79 per Mcf, applied to the 40 Mcf a year the furnace burns, puts its running cost near $973 a year, against 16.58¢ per kWh for electricity. Looked at as a full purchase rather than an incremental one, payback here is roughly 53.8 years, leaving the 15-year total $264 ahead.
Electric resistance heat in Leesburg, compared
Plenty of homes in Leesburg heat with electricity alone, no gas line involved. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $1,196 a year, which recovers the extra $8,000 spent going electric in roughly 6.7 years.
Where Leesburg ranks in this dataset
Ranked against the other 3206 cities covered, Leesburg comes in at 1612 for heating severity — 1 would be the coldest place in the dataset — and 822 by population, where 1 is largest. That's the middle third for winter severity among the cities covered here.
Deciding what's next in Leesburg, VA
Leesburg, Virginia is home to about 49,831 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 Leesburg, nothing is lost by holding off until the current equipment genuinely fails.

More on how this number was built
Every constant behind this page — the 3.08 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Leesburg's 15.8°F design temperature is below the 25°F line, which is why a cold-climate unit is the right call here — see what that changes in the cold-climate unit guide.
