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?
Sizing, efficiency tier and brand pull a quote in different directions. Here's how our editors weigh the trade-offs that decide what you actually pay.
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
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 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.
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.
