Signs It’s Time to Replace Your Furnace

Most furnaces last around 15–20 years, but their lifespan depends on maintenance, usage, and installation quality. If you’re noticing any of the issues below, it may be time to replace your furnace in Eugene, OR, instead of continuing to invest in repairs.

If you’re wondering when to replace a furnace in Eugene, start with the unit’s age, repair frequency, efficiency changes, and any safety red flags.

Common replacement signals include:

  • Age and wear: A furnace nearing or past 15–20 years is more likely to break down and less likely to run efficiently.
  • Frequent repairs: If you’re calling for service more than once a season, costs add up fast.
  • Rising heating bills: Declining efficiency can show up as steadily higher winter utility costs.
  • Uneven heat or weak airflow: Cold rooms, short cycling, or long run times can indicate the system is no longer performing properly.
  • Unusual noises or smells: Rattling, booming, scraping, or persistent burning odors can be signs of failing components.
  • Comfort and air quality concerns: Dusty air, excessive dryness, or poor circulation can worsen as older equipment struggles.

Safety Concerns You Shouldn’t Ignore

If a technician identifies a cracked heat exchanger, replacement is typically the safest option. A compromised heat exchanger can increase the risk of carbon monoxide issues and should be treated as an urgent priority. Keep carbon monoxide detectors in working order and contact a professional if you suspect a problem.

Repair vs. Replace: How to Decide

Not every issue means you need a new furnace. If your system is relatively new and the repair is minor, a repair can be the smart move, especially if the furnace has a solid service history.

Replacement often makes more sense when:

  • The furnace is older (15+ years) and needs a major repair.
  • Repairs are becoming frequent, unpredictable, or expensive.
  • You want improved comfort (quieter operation, steadier temperatures, better airflow).
  • Efficiency is clearly declining, and you’d benefit from modern high-efficiency performance.
  • A safety issue is present, such as a heat exchanger concern.

If you’re unsure, start with an inspection and straight answers. If a repair is the best path, see our furnace repair service for help getting your heat back quickly.

What to Expect: The Furnace Replacement Process

A professional replacement is more than swapping boxes. Proper sizing, venting, airflow, and commissioning are what make a new furnace perform the way it should.

Here’s what a typical furnace replacement service includes:

  1. Home assessment and options: We look at your current system, comfort goals, and any issues like hot/cold rooms or airflow problems.
  2. Right-sizing (not guess-sizing): The best replacements are based on your home’s needs, not the size of the old unit.
  3. Clear estimate and equipment selection: We review efficiency levels, features, and what fits your budget.
  4. Installation planning: This can include venting changes for high-efficiency models, thermostat upgrades, and duct connections.
  5. Removal and haul-away: The old furnace is disconnected safely and removed.
  6. New furnace installation: Gas, electrical, venting, condensate for high-efficiency, and airflow components are installed to manufacturer specs.
  7. Start-up and testing: We verify safe operation, proper combustion/venting, and correct airflow and temperature rise.
  8. Walkthrough: You’ll know how to operate your system and what to expect for filter changes and maintenance.

Most furnace replacements can be completed in a single visit, but some upgrades (especially high-efficiency models) may require venting changes, condensate routing, or thermostat and control updates. If we find issues that would limit performance, like major duct restrictions or unsafe venting, we’ll explain what we’re seeing and the options to correct it.

To make comparisons easier, here are a few helpful questions to ask when you’re evaluating estimates for a new furnace in Eugene:

  • How was the furnace sized for my home?
  • What efficiency level (AFUE) am I choosing, and why?
  • Are venting, drainage, and airflow details included in the scope?
  • What maintenance is recommended to protect efficiency and reliability?

If you’re comparing options, our furnace installation page covers what a quality install should include.

Energy Savings: Why New Furnaces Make a Difference in Eugene

Eugene homeowners often heat their homes for a large portion of the year, so efficiency can have a real impact. Many older furnaces operate around 80% AFUE (Annual Fuel Utilization Efficiency), while modern high-efficiency units can reach 95%+ AFUE.

That efficiency improvement can translate to meaningful savings over time, often 20–40% more efficient compared with older equipment, depending on what you’re replacing and how your home is used.

Beyond energy savings, newer furnaces can also deliver:

  • More consistent temperatures with better staging (two-stage or modulating heat)
  • Quieter operation with improved blower and cabinet design
  • Better airflow and filtration compatibility, which can support comfort and cleaner indoor air

High-Efficiency Furnace Options for Pacific Northwest Homes

If you’re upgrading your system, it’s worth choosing features that match how homes in the Eugene area are heated: frequent run times, varying outdoor temperatures, and a need for consistent comfort.

If you’re planning to upgrade your furnace in Eugene, we’ll help you compare options that balance upfront cost with long-term comfort and efficiency.

Popular high-efficiency options include:

  • 95%+ condensing furnaces: These extract more heat from combustion and typically use PVC venting and a condensate drain.
  • Two-stage furnaces: Run on a lower stage most of the time for steadier heat, then ramp up when it’s colder.
  • Modulating furnaces: Adjust output in small increments for the most even comfort and often the best efficiency.
  • Variable-speed blowers: Improved airflow control can reduce noise and help with filtration and air circulation.
  • Sealed combustion: Helps reduce drafts and improves safety by drawing combustion air from outside.

Furnace Replacement Cost in Eugene: What Affects the Price?

The cost to replace a furnace in Eugene depends on your home, your equipment choice, and what’s required to install the system correctly. As a general ballpark, many installed replacements fall roughly in the $5,000–$12,000 range, but the total can be lower or higher based on project details.

Key cost factors include:

  • Furnace size and output: Proper sizing matters for comfort and longevity.
  • Efficiency level (AFUE): Higher efficiency can cost more up front, but may reduce energy use.
  • Features and comfort upgrades: Two-stage/modulating heat, variable-speed blowers, filtration cabinets, and smart thermostat compatibility.
  • Venting and condensate needs: High-efficiency furnaces often require different venting and a condensate drain setup.
  • Ductwork condition: Leaky or undersized ducts can limit performance and may need adjustments.
  • Electrical and gas connections: Sometimes updates are needed to meet code or manufacturer requirements.
  • Permits and inspections (when required): Proper documentation helps ensure safe, compliant installation.
  • Removal and disposal: Haul-away, recycling, and safe disposal are part of a complete replacement.

You may also be able to reduce your net cost over time by choosing equipment that lowers energy use and by taking advantage of available incentives. Rebates, utility programs, and tax credits change, but we can help you understand which efficiency levels and system types may qualify at the time of your estimate.

If you’re looking specifically at furnace replacement cost in Eugene, the fastest way to get accurate pricing is an in-home estimate that accounts for your home’s layout and your comfort goals.

Responsible Removal and Disposal of Your Old Furnace

Replacing a furnace should also mean getting rid of the old one the right way. We remove and haul away the existing unit, recycle materials where possible, and dispose of the remaining components responsibly. If your system includes additional equipment, like an A/C coil or other accessories, we’ll review what stays and what should be updated during the replacement.

Financing Options for a New Furnace

A new furnace is a major upgrade, and financing can make it easier to move forward without delaying a needed replacement. Ask Priority One Heating about available financing options and any seasonal opportunities that may help spread the cost over time.
