Furnace Installation & Replacement in Boise

Replacing a furnace in the Treasure Valley isn't one-size-fits-all. A 1910 North End craftsman with original gravity-heat bones has completely different needs than a two-story in a new Kuna subdivision. We run a proper Manual J load calculation on your home — not a guess based on the old unit's size — because an oversized furnace short-cycles, wears out early, and leaves rooms unevenly heated.

We'll walk you through the efficiency tradeoff honestly: with Intermountain Gas rates and Boise's real winter, a 96% AFUE high-efficiency furnace pays back faster here than in milder climates — especially in larger two-story homes. Either way, you'll get a written, itemized quote — equipment, labor, permits, and haul-away — before we schedule anything.

What We See Most in Boise

• Your furnace is 15+ years old and repairs are stacking up
• Cracked heat exchanger — a carbon monoxide risk, not a repair item
• Heating bills climbing every winter despite tune-ups
• Some rooms never get warm no matter how long it runs
• Furnace is oversized and short-cycles constantly
• You're switching from electric resistance heat to natural gas to cut bills

What a New Furnace Costs in the Treasure Valley

Service	Typical Boise Price

Every install quote includes removal and disposal of the old unit, new gas flex connector and shutoff as needed, thermostat wiring check, startup testing, and manufacturer warranty registration. Permits pulled where required — Boise, Meridian, Nampa, and Ada/Canyon County each have their own process.
