Cheapest time for furnace replacement in either city
Crews are busiest — and priciest — exactly when it's hottest or coldest, since that's when systems fail under load. Book in the mild months and you're negotiating from a position of choice, not a broken furnace.
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 efficiency-first case
Where you face brutal summers or hard winters, a higher SEER2/AFUE system or a heat pump runs enough hours to claw back its premium through lower bills — and utility or state rebates can still trim the sticker even though the federal 25C/25D credits closed at the end of 2025. Do the payback arithmetic before you reach for the cheapest box on the lot.
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
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.
Climate decides the efficiency tier; a proper load calculation decides everything else. Nail both, stack the rebates you can, and you've sidestepped the two mistakes — wrong size, rushed install — that actually inflate the lifetime cost.
