Heat pump vs. gas furnace in Laredo, TX

Laredo is a clear case: a heat pump beats what you have by a wide margin. 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). Lower bills claw that back: about $381 saved annually, for a payback of roughly 2.6 years. Nothing about that conclusion is generic — it's built entirely from Laredo's own numbers.

Why Laredo's climate drives this number

Laredo barely has a winter to speak of — 538 heating degree days a year against a 65°F base — and summers are severe enough that cooling can dominate the annual bill, at 4810 cooling degree days. 28.9°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 24.1°F on file. Worked through the model, that's a seasonal COP of 3.06 on the standard unit fit for this climate. A standard ducted system is enough here; Laredo's design temperature doesn't justify the cold-climate premium. Climate figures trace to the nearest NOAA station, LAREDO INTERNATIONAL AIRPORT, 2.3 miles from Laredo.

The month-to-month numbers for Laredo

A 2000-square-foot house here would pull roughly 445 heating kilowatt-hours annually on top of cooling, totalling about $734 a year on electricity. That compares with roughly 6 Mcf a year of gas at Laredo's 19.42 per-Mcf rate — about $1,116 a year — against a local electricity rate of 16.15¢/kWh. Buy it outright, not incrementally, and payback stretches to 28.8 years; over 15 years the net position sits $4,720 ahead.

The other scenario: no gas furnace to begin with

Plenty of homes in Laredo heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Laredo's answer improves. The saving here runs about $493 a year, which recovers the extra $5,500 spent going electric in roughly 11.2 years.

Laredo against the rest of the country

Laredo lands at position 3045 out of 3206 cities on heating severity (coldest is 1), and 87 out of 3206 by population size (biggest is 1). 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 Laredo

About 261,260 people live in Laredo, Texas, and every number on this page is what a contractor would actually work from when quoting a system here — the point isn't to replace that quote, it's to tell you whether to bother asking for one. Here, it's worth getting quotes before your current system fails, not after.

Ask a local HVAC contractor for a quote before committing either way.
