What hvac pros earn in each metro

Cheapest time for furnace replacement in either city
HVAC demand collapses in the mild shoulder seasons, so installers discount to keep crews busy. The most expensive time to buy is during a heat wave or cold snap, when a dead system forces a full-price emergency replacement.
How much should you really budget for HVAC in 2026?
Ask five contractors for an HVAC quote and you'll get five different numbers — usually because they disagree on sizing, efficiency and equipment tier. Here's how our editors think through those trade-offs.
The efficiency-first case
In a hot-summer or cold-winter region, a higher SEER2/AFUE unit — or a heat pump — earns its premium back in lower bills, and utility and state rebates can still cut into the sticker (the federal 25C/25D credits ended Dec 2025). Run the payback math before defaulting to the cheapest box.
The longevity case
The single biggest cost driver isn't the brand — it's correct sizing and install quality. A properly sized, well-commissioned mid-tier system with annual maintenance outlasts an oversized premium unit that short-cycles. Spend on the install, not the badge.
The budget-first case
Size the system to your home with a Manual J calculation and buy the standard efficiency tier (80% AFUE / 14.3 SEER2). In a mild climate the cheaper unit pays off because you rarely run it hard — paying for premium efficiency you won't use is the most common way to overspend.
Match the efficiency tier to your climate, insist on a real load calculation, and stack every rebate you qualify for. The expensive mistakes are wrong sizing and a rushed install — not picking the "wrong" brand.

It's not a myth — BLS data puts installer wages at about $23.7/hr in the El Paso area and $28.4/hr in San Antonio-New Braunfels. Given labor is around 60% of a furnace replacement job's cost, that gap explains most of the price spread.
When is the cheapest time to buy furnace replacement — and does it differ by city?
Timing doesn't change by city here — Spring and fall (Mar–May, Sep–Oct) is the cheapest window in both El Paso and San Antonio, saving roughly 5–15%. Avoid peak summer and mid-winter in either location, when emergency replacements push prices up.
Should I choose where to live based on furnace replacement cost?
Probably not. Yes, $450 is a real gap, but it's a one-time cost you can partly offset in San Antonio with off-season timing and tighter bids. Long-term factors like energy prices and home condition matter more than this one number.
