Is the gap worth worrying about?
A 15% gap is meaningful on a project this size — about $1,850. That's real money, but it's often within reach of off-season timing and a tighter apples-to-apples bid in San Francisco.

Cheapest time for full HVAC system replacement in either city
Installers cut prices in spring and fall because job volume drops and crews sit idle — the opposite happens during a summer heat wave or winter cold snap, when a dead system forces homeowners into a full-price emergency swap.
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
In a hot-summer or cold-winter region, a higher SEER2/AFUE unit — or a heat pump — earns its premium back in lower bills, and utility and state rebates can still cut into the sticker (the federal 25C/25D credits ended Dec 2025). Run the payback math before defaulting to the cheapest box.
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.
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.
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.
