What hvac pros earn in each metro

Cheapest time for furnace replacement in either city
A furnace or AC that dies mid-heat-wave gets replaced at whatever the on-call crew charges. One that gets swapped in April or October gets a competitive, unhurried quote instead.
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
Where you face brutal summers or hard winters, a higher SEER2/AFUE system or a heat pump runs enough hours to claw back its premium through lower bills — and utility or state rebates can still trim the sticker even though the federal 25C/25D credits closed at the end of 2025. Do the payback arithmetic before you reach for the cheapest box on the lot.
The budget-first case
Run a Manual J load calculation, then buy the standard tier — 80% AFUE, 14.3 SEER2 — and stop there. Where summers are short and winters are gentle, the equipment idles most of the year, so premium efficiency never gets enough runtime to earn back its price. Paying for SEER2 you'll rarely tap is the classic way a mild-climate homeowner overspends.
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.
Skip the brand debate. A correctly sized system, an efficiency tier that fits your climate, and a properly commissioned install will save you more than any label ever could.
Dallas vs San Antonio
Is furnace replacement cheaper in Dallas or San Antonio?
San Antonio comes out ahead here, at roughly $5,050 for furnace replacement compared with $5,250 in Dallas — a 4% ($200) gap as of 2026.
Why does furnace replacement cost more in Dallas than San Antonio?
Dallas's higher labor index (0.97 vs 0.95 in San Antonio) is the biggest factor, with the hot/hot climate split and permit fee differences playing a smaller role.
How much is furnace replacement in Dallas, TX?
In Dallas, furnace replacement typically runs $3,750–$6,700 in 2026, with most homeowners paying around $5,250.
Do hvac pros really charge more in one city?
It's not a myth — BLS data puts installer wages at about $29.7/hr in the Dallas-Fort Worth-Arlington 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.

No, the seasonal pattern is the same in Dallas and San Antonio: book during Spring and fall (Mar–May, Sep–Oct) for about 5–15% in savings. Peak summer and mid-winter is the priciest stretch in both cities, mostly due to emergency replacements.
Should I choose where to live based on furnace replacement cost?
Probably not. Yes, $200 is a real gap, but it's a one-time cost you can partly offset in Dallas with off-season timing and tighter bids. Long-term factors like energy prices and home condition matter more than this one number.
