What hvac pros earn in each metro
Labor is about 60% of a furnace replacement bill, so local wages drive most of the gap. These are real metro hourly wages for skilled installers (BLS OEWS), not estimates.

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 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.
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 longevity case
The most expensive variable on the quote isn't the logo — it's whether the system is sized right and installed well. Oversize a premium unit and it short-cycles, wears fast and underperforms; commission a correctly sized mid-tier one and keep up the annual service, and it simply lasts longer. Spend on the installation, not the badge.
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.
Frisco vs San Antonio
Is furnace replacement cheaper in Frisco or San Antonio?
Yes — San Antonio costs more. Expect around $5,050 for furnace replacement there against $4,650 in Frisco, about $400 (9%) apart in 2026.
Why does furnace replacement cost more in San Antonio than Frisco?
San Antonio's higher labor index (0.95 vs 0.87 in Frisco) is the biggest factor, with the hot/hot climate split playing a smaller role.
How much is furnace replacement in Frisco, TX?
Frisco homeowners can expect $3,350 to $5,950 for furnace replacement in 2026, with $4,650 the typical number.
Do hvac pros really charge more in one city?
Yes — and the wage data shows it. A skilled installer earns about $24.2/hr in the McAllen-Edinburg-Mission area versus $28.4/hr around San Antonio-New Braunfels (BLS metro wage data). Since labor is roughly 60% of a furnace replacement job, that wage gap is the biggest reason the installed prices differ.
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 Frisco 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, $400 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.
