What hvac pros earn in each metro
About 60% of a full HVAC system replacement bill goes to labor, so wage differences between these two metros matter more than almost anything else. These are real, government-sourced (BLS OEWS) installer wages, not estimates.

Cheapest time for full HVAC system replacement in either city
Demand for HVAC work falls off a cliff in the shoulder months, and contractors discount to keep their crews booked. Wait for a 100-degree day or a hard freeze, though, and you're paying emergency rates for a system that just quit.
How much should you really budget for HVAC in 2026?
What you pay for HVAC hinges less on the badge than on how the quote is built — the load calculation behind it, the efficiency tier, and the markup. Our take on where each one lands.
The efficiency-first case
High runtime changes the math. In a demanding climate the extra efficiency of a heat pump or a top-tier SEER2/AFUE unit gets paid back month after month on the utility bill, and state and utility incentives can shave the upfront figure further now that the federal 25C/25D credits have expired. Price the lifetime bills, not just the tag, before you default down.
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.
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 costly errors in an HVAC job are a bad load calculation and a sloppy install — not the logo you chose. Size it with a real Manual J, let your climate set the efficiency tier, and claim whatever rebates you still qualify for.
