How Much Does Furnace Replacement Cost in Southern Oregon?
Published national cost guides for 2026 put gas furnace replacement at roughly $2,500 to $8,000 installed. At Stone Heating and Air in Central Point, we see Southern Oregon homes land all across that range — where yours falls depends on home size, ductwork condition, electrical panel capacity, and the equipment tier you choose. A ducted heat pump or a full AC-plus-furnace system costs more, which is why an honest quote starts with your house, not a phone-call average.
This guide is the conversation we'd have with you at your kitchen table: what the published numbers actually say, how a furnace compares to a heat pump for cold Rogue Valley winters, what those efficiency ratings mean in plain English, and when replacement genuinely beats another repair. If your heat is out right now on a freezing night, skip ahead to our guide on what to do when your furnace fails on a cold night and call us — we're on call 24/7. Otherwise, our heating installation and replacement in the Rogue Valley team can turn this general picture into a firm number for your home.
What Do Furnace and Heat Pump Replacements Cost Nationally in 2026?
A gas furnace replacement in the Rogue Valley typically falls somewhere inside the national 2026 range of roughly $2,500 to $8,000 installed, with the spread driven by equipment tier, venting, and how much work the surrounding system needs. Here's how published national cost guides for 2026 compare the three paths most Southern Oregon homeowners weigh:
• Gas furnace replacement — National installed range (2026): Roughly $2,500–$8,000 — What it covers: New furnace on your existing ductwork; keeps your current AC
• Ducted heat pump — National installed range (2026): Roughly $4,500–$14,000 — What it covers: One system that heats and cools; cold-climate models at the top of the range
• Full system (AC + furnace) — National installed range (2026): Roughly $6,500–$16,000 — What it covers: Both sides replaced at once with matched equipment
These are national published ranges, not a local price list — and the honest truth is that no contractor can tell you where your home lands without looking at it. Ductwork that needs sealing or repair, an electrical panel that's already full, a larger home that needs more capacity, or a jump from builder-grade to variable-speed equipment each move the number. That's exactly why we quote firm prices after evaluating the home instead of quoting a made-up "average price in Medford."
Gas Furnace or Heat Pump: Which Makes Sense for Rogue Valley Winters?
For most Southern Oregon homes, both options genuinely work — Rogue Valley winters bring freezing nights and long stretches of valley inversion fog, but modern cold-climate heat pumps are built for exactly this kind of climate, and gas furnaces remain a proven, lower-upfront-cost choice. The right answer depends on your fuel situation, your cooling needs, and your budget, not on a blanket rule.
• A gas furnace usually costs less up front, delivers hot, fast heat, and is a straightforward swap if you already have gas service and healthy ductwork. If your AC is newer and you only need to solve heating, this is often the simplest path.
• A ducted heat pump replaces both your furnace and your air conditioner with one system — a real advantage in a valley where summers regularly hit 100°F and cooling is not optional. It costs more up front, but you're buying two systems' worth of function, and extended-capacity cold-climate models are designed to keep producing heat through freezing Rogue Valley nights.
• Electric-resistance heat households have the strongest case for a heat pump, both on operating logic and on incentives: the 2026 Energy Trust of Oregon ducted heat pump incentive specifically applies when the heat pump replaces an electric forced-air furnace as primary heat.
Incentives can tilt the math. Energy Trust of Oregon's 2026 residential incentives — available to Oregon customers of Portland General Electric or Pacific Power, and much of the Rogue Valley is Pacific Power territory — include $1,000 for a standard owner-occupied ducted heat pump (HSPF2 7.50 or better, replacing an electric forced-air furnace as primary heat), $3,000 for rentals, attached homes, or income-qualified Savings Within Reach households, and $1,000–$2,000 for extended-capacity cold-climate models. Amounts are reviewed annually, so confirm current figures at energytrust.org before signing. One thing not to count on: the federal 25C tax credit for heat pumps was terminated and doesn't apply to equipment placed in service after December 31, 2025.

What Do AFUE Efficiency Tiers Actually Mean?
AFUE — Annual Fuel Utilization Efficiency — measures how much of the fuel a furnace burns actually becomes heat in your home, with the rest lost up the flue. A higher AFUE rating means less wasted fuel for the same warmth, and it's the single clearest spec for comparing one furnace against another. In practice, furnaces sort into two broad tiers:
• Standard-efficiency furnaces are the entry tier: lower purchase price, conventional venting, and proven reliability. For a tight budget or a home you don't plan to stay in long, they're a legitimate choice — a properly installed standard-efficiency furnace beats a poorly installed premium one every time.
• High-efficiency condensing furnaces capture extra heat from the exhaust that standard models send up the flue, which is what earns them their higher AFUE ratings. They cost more up front and use different venting, but they waste less of every heating dollar across the cold months — and Rogue Valley winters give them plenty of runtime to make that difference felt.
• Staging and blower type matter alongside AFUE. Two-stage and variable-speed (modulating) furnaces run longer at lower output, which means steadier temperatures, quieter operation, and fewer of the hot-cold swings you feel with a single-stage unit cycling on and off through a freezing night.
Our advice as the people who install and then service these systems: don't buy AFUE in isolation. A high-efficiency furnace attached to leaky ductwork loses its advantage in the crawl space. When we quote a replacement, we look at the whole delivery path — furnace, ducts, controls — because our motto is "do the job right the first time," and efficiency ratings only hold up when the installation does.
When Does Replacement Beat Another Repair?
Replacement beats repair when the repair bill is large relative to the equipment's remaining life — an aging furnace with a failing heat exchanger is a replacement conversation, while a young furnace with a bad igniter is just a repair. The pattern we watch for is repeat failures: if you're calling for the second or third significant repair in a couple of winters, each fix is buying less time than the one before it.
There's also a safety dimension with gas equipment. A cracked heat exchanger isn't something to patch and hope; it's a genuine replace-now situation, and our NATE-certified technicians will show you what they found rather than asking you to take it on faith. For the borderline cases — where the furnace still runs but the math is getting questionable — our repair-or-replace guide and the $5K rule gives you a simple, unemotional framework for the decision.
And if the numbers say replace but the timing is hard, you don't have to pay it all at once: we offer financing through GreenSky, and our GreenSky financing guide explains how the application and payment options actually work before you're standing in a cold house making a rushed decision.
Frequently Asked Questions About Furnace Replacement Cost
Why do furnace replacement quotes vary so much between homes?
Because the furnace is only part of the job. Ductwork condition, venting requirements, electrical panel capacity, home size, and equipment tier all differ house to house, and each moves the price. Two neighbors in Medford can get honestly different quotes for the same model of furnace — which is why we price from an evaluation of your home, never from a phone script.
Is a high-efficiency furnace worth the extra cost?
Often, but not always. A high-efficiency condensing furnace wastes less of every heating dollar and gets plenty of runtime in a Rogue Valley winter, so the longer you plan to stay in the home, the stronger the case. On a tight budget or a short ownership horizon, a properly installed standard-efficiency furnace is a legitimate choice. We'll quote both tiers so you can compare real numbers instead of guessing.
Should I switch from a gas furnace to a heat pump?
It depends on your fuel situation and cooling needs. If your AC is also aging, a ducted heat pump replaces both systems at once, and cold-climate models handle freezing Rogue Valley nights. If you heat with an electric forced-air furnace, 2026 Energy Trust of Oregon incentives of $1,000 to $3,000 may apply for qualifying ducted heat pumps — confirm current amounts at energytrust.org and check that you're a Pacific Power or PGE customer.
How long does a furnace replacement take?
A straightforward like-for-like gas furnace swap on healthy ductwork is typically about a day. Add time for venting changes, duct repairs, electrical work, or a conversion to a heat pump. When we quote your project we include the expected timeline, so you know how long you'll be without heat — and in winter we plan the work to keep that window as short as possible.
Can I finance a furnace replacement?
Yes. Stone Heating and Air offers financing through GreenSky, which lets you spread the cost of a replacement into monthly payments instead of one lump sum. It's especially useful when a furnace dies mid-winter and the decision can't wait for savings to catch up. Ask us about current options when you get your quote, or see our financing page for details.
Who should I trust to do the replacement?
Look for a licensed contractor who inspects your home before quoting, prices in writing, and stands behind the installation. Stone Heating and Air is licensed (Oregon CCB #224159), a Carrier Factory Authorized Dealer with NATE-certified technicians, and 4.9-star rated by Southern Oregon homeowners — and we've built our reputation on doing the job right the first time.
