What hvac pros earn in each metro

Cheapest time for furnace 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?
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 budget-first case
In a temperate region the smart move is to size the job correctly with a Manual J and take the base efficiency tier. A system that spends most days coasting can't recover the cost of a high-SEER2 compressor, because the savings only show up under heavy load you don't put on it. Match the equipment to how little you actually run it, not to the brochure's top number.
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 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.
Get the sizing and the commissioning right and the brand debate mostly disappears. Insist on a Manual J, pick an efficiency tier your climate can justify, and pocket every incentive that still applies after the federal credits lapsed.
