Is the price difference a dealbreaker?
That 4% gap is small — for furnace replacement it's usually less than the spread between two local contractors' quotes, so the metro matters far less than who you hire and when you buy.

What hvac pros earn in each metro
Since labor accounts for around 60% of what a furnace replacement job costs, it's the biggest lever behind any price gap between cities. What you're seeing below is actual BLS metro wage data for skilled installers — not a guess.

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?
An HVAC budget isn't one number — it's a set of trade-offs between sizing accuracy, efficiency tier and brand. Our editors walk through how each one moves the price.
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
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 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.

Should I choose where to live based on furnace replacement cost?
That would be a stretch. $250 is a one-time difference, not an ongoing one, and off-season buying plus apples-to-apples bids in San Diego can close a good chunk of it. What matters more long-term is energy costs, climate and the condition of the home.
