Repair vs. replace
Six signs it's time to replace your furnace.
Newer systems are usually worth fixing. Older systems with multiple symptoms below are usually not. We'll model both paths side-by-side at the estimate so you can decide with real numbers — not a sales pitch.
System is 12+ years old
Furnaces typically last 15–20 years with maintenance. Past 12, efficiency drops noticeably and parts get harder to source.
Repair cost > 50% of replacement
If a quoted repair is more than half of a new system, especially on an older unit, replacement usually wins on a 10-year horizon.
Bills are climbing
A 12-year-old 80% AFUE unit burns ~20% more gas than a new 96% unit doing the same work. The math compounds every winter.
Long, uneven cycles
Some rooms freezing while others bake, thermostat fiddling, longer run times — classic late-life furnace symptoms.
Strange noises
Bangs at startup (delayed ignition), screeches (blower bearing), rattles (loose internals) — often signal end-of-life.
Safety concerns
Cracked heat exchanger, yellow flames, or persistent CO alarms — replace, don't patch. Carbon monoxide is not a corner to cut.
Smell gas, see a yellow flame, or hear a constant hiss? Shut the system off, leave the house, and call us — or 911 if it's urgent. Don't troubleshoot a gas leak yourself.
What's included
What we include in every furnace installation — four things most don't.
Anyone can swap a box. We do the work that makes the system actually last.
Manual J load calculation
Properly sized for your home — not rule-of-thumb guessed. Right-sized furnaces run quieter, last longer, and waste less gas.
High-efficiency equipment
Trane and American Standard gas furnaces, 92–97% AFUE on most replacements. Real efficiency gains over a 12+ year-old 80% unit.
Manufacturer-spec install
Vent sizing, gas-line check, combustion analysis, and electrical all to factory spec. The reason warranties stay valid.
Old system removal
We pull and dispose of the old furnace, recycle the metal, and leave the mechanical room cleaner than we found it.
On install day
Built to manufacturer spec — what installation by the book actually means.
Wire-by-wire to the factory diagram. Gas line sized for the BTU input, vent pitched correctly, condensate routed properly. The reason our installs hold up past warranty — and the reason most don't.
- Combustion analysis and start-up calibration
- Drop cloths, shoe covers, vacuum running
- Permit pulled and inspection scheduled
Right-sizing matters
Right-sizing your furnace — bigger isn't better.
Most furnaces in metro homes are oversized. Installers default up a tier to be “safe.” The trade-off is short-cycling, uneven heat, and a system that wears out years early. Manual J load calculation gets you the size your house actually needs.
Undersized
Runs constantly, never quite catches up. Comfort suffers, the blower wears prematurely, and the system fails years early from being overworked.
Oversized
Short-cycles: turns on, blasts heat, shuts off, repeats. Wear-and-tear from constant cycling, uneven temperatures, and worse efficiency than a smaller right-sized unit.
Right-sized
Runs in long, steady cycles that distribute heat evenly. Quieter, more efficient, and lasts the full 15–20 years it's rated for.
Manual J on every install. Square footage, insulation R-values, window area, ceiling height, climate zone, duct condition. The real calculation — not a rule of thumb — so the system you buy actually fits your house.
How it works
Our furnace installation process — four steps from cold house to fully installed.
- 01
Free in-home estimate
Manual J load calculation, ductwork inspection, gas-line check, written quote — all in the first visit.
- 02
Equipment + financing
We walk through three honest options. Wells Fargo financing applied at the kitchen table — most decisions same day.
- 03
Install day
Most replacements are a same-day job. Drop cloths down, vacuum running, the new system on and tuned before we leave.
- 04
Permit + warranty
We pull the permit, schedule the inspection, and register the warranty in your name. Paperwork lands in your inbox.
- Trane Comfort Specialist
- Manufacturer-spec installs
- Permit + inspection handled
- Wells Fargo 0% financing
After the install
Annual maintenance keeps the new system running like new, and keeps the warranty valid.
Trane and American Standard warranties require documented yearly service. Our Comfort Care plans handle scheduling, tune-ups, and member-rate repairs.
Furnace installation questions, answered.
- Most replacements run $4,500–$9,500 installed, depending on AFUE rating, size, and whether ductwork or gas-line work is needed. We give a real number at the in-home estimate — not a guess over the phone.
- Manual J load calculation. It accounts for square footage, insulation, window count, ceiling height, climate zone, duct condition, and orientation. Square-footage rules of thumb are notoriously wrong. That's how most homes end up oversized. We do the calc on every install.
- Most direct replacements are a same-day install. Full conversions (gas line, new ductwork, new venting) can stretch to 1–2 days. We'll tell you the realistic timeline at the estimate.
- If your AC is also aging, almost certainly yes. A heat pump replaces both your furnace and AC, qualifies for $1,500–$3,000+ in rebates, and runs efficiently in our mild climate. We'll show the side-by-side at the estimate.
- For installations, yes — those are the brands we trust to last. We service every major furnace brand for repair, regardless of who installed it originally.
- Energy Trust of Oregon offers rebates on high-efficiency 95%+ AFUE gas furnaces. Heat pumps qualify for substantially larger incentives. We'll model both at the estimate so you can compare.
- Headquartered in Oregon City, we serve the Portland metro across Clackamas, Multnomah, and Washington counties: Portland, Beaverton, Gresham, Lake Oswego, West Linn, and Clackamas.
