About this service

What furnace replacement Milwaukie OR actually involves

Furnace replacement Milwaukie OR is the removal of your old gas or electric furnace and the installation of a new one that matches your home's actual heat load. We pull the old unit, inspect the heat exchanger and flue, then set a new Carrier, Trane, or Lennox furnace on a level pad. Copper tubing, PVC condensate lines, and sheet metal ductwork get checked and sealed before we fire it up.

Most Milwaukie homes built before 1990 still run original 80% furnaces. When those fail in January, you need heat fast. We stock Goodman and Rheem units locally so same-day furnace replacement Milwaukie OR is often possible. If you're pricing a new furnace Milwaukie, we give you a written quote before any work starts.

  • ✓ Lower winter gas bills
  • ✓ Heat that actually reaches rooms
  • ✓ No more 2 a.m. breakdowns
  • ✓ Code-correct, permitted install
What's included

What our furnace replacement includes

Every furnace replacement we do in Milwaukie includes the core work below. Add-ons like duct repair, AC install, or smart thermostats get quoted separately so you see exactly what you're paying for.

01
✓

Old furnace removal

We disconnect gas and electrical, recover any refrigerant if applicable, and haul the old unit away. No extra fee for disposal. We leave the pad clean and ready for the new furnace.

02
✓

New furnace installation

We set the new unit, connect gas lines, braze copper tubing, run a PVC condensate line, and wire the thermostat. Every connection is leak-tested before we fire the furnace.

03
✓

Duct inspection and sealing

We check accessible ductwork for leaks, disconnected joints, and crushed sections. We seal what we can reach with mastic and foil tape. Major duct repairs get quoted before we proceed.

04
✓

Combustion and safety testing

We run a combustion analysis, check gas pressure, and verify the flue is drafting properly. Carbon monoxide levels get tested. You get a signed checklist showing the furnace is safe to run.

05
✓

Permit and inspection

We pull the Oregon mechanical permit and schedule the Clackamas County inspection. You get the paperwork for your records. This matters at resale and keeps your warranty valid.

06
✓

Thermostat setup

We install and configure your thermostat, whether it's a basic model or a Nest or Ecobee. You get a walkthrough of schedules, filter reminders, and how to shut the system down if needed.

How it works

How our furnace replacement process works

You call (855) 947-9500 and describe the symptoms. If the furnace is dead, we book a same-day visit. If it's limping, we schedule a diagnostic. Either way you get a 2-hour arrival window, not a vague all-day promise.

A NATE-certified tech measures your home, checks insulation, window count, and existing duct size. We run an ACCA Manual J load calc so the new furnace isn't oversized. Oversized units short-cycle and wear out fast. This takes 45-60 minutes.

You get a line-item quote: furnace model, labor, permit, thermostat, and any duct repairs. No surprise add-ons. We walk you through Carrier, Trane, Goodman, and Rheem options at three price points so you choose with real numbers in front of you.

We arrive with the new unit, recovery machine, and vacuum pump. Old furnace comes out, new one goes in. We braze copper tubing, run a new PVC condensate line, seal duct connections, and wire the thermostat. Most swaps take 6-8 hours.

Before we leave we check static pressure with a manometer, verify gas pressure with a multimeter and clamp meter, and run a combustion analysis. You get a walkthrough of the thermostat, filter location, and shutoff. We don't leave until the heat is steady.

Tools & methods

Tools and methods we use

01
✓

Manifold gauges

Used to check gas pressure and verify the new furnace is running at the manufacturer's specified input. Wrong pressure means poor combustion and premature failure.

02
✓

Vacuum pump and recovery machine

If your system has AC or a heat pump, we recover refrigerant properly and pull a deep vacuum before recharging. EPA Section 608 rules require it.

03
✓

Multimeter and clamp meter

We test voltage, amperage, and continuity on the blower motor, control board, and igniter. Catching an electrical fault before startup prevents callbacks.

04
✓

Leak detector

We check every gas connection with an electronic leak detector and soap solution. A gas leak is not something we leave to chance.

05
✓

Tube bender and fin comb

Copper tubing gets bent cleanly to fit the new unit. A fin comb straightens condenser fins if we're working on the AC side during the same visit.

06
✓

Duct cleaning vacuum

When ducts are full of debris, we vacuum them out before the new furnace pushes air through. Your new system starts clean.

1994 furnace to 96% AFUE in Ardenwald

A 1994 80% furnace was short-cycling and leaving the back bedrooms cold. Gas bills had climbed to $210 a month in winter. The heat exchanger showed early cracking.

After: We installed a 96% AFUE variable-speed furnace, sealed accessible ductwork, and balanced airflow. Winter gas bills dropped to about $145 a month. Bedrooms now heat evenly.

Same-day emergency swap in Milwaukie Heights

A homeowner called at 7 a.m. on a January morning with no heat and a furnace that wouldn't ignite. The house was at 52 degrees and dropping. Two kids at home.

Furnace plus AC bundle in North Clackamas
furnace replacement

Furnace plus AC bundle in North Clackamas

A 2003 furnace and AC were both near end of life. The homeowner wanted to replace both but expected two separate projects and two permits.

After: We replaced the furnace and installed a matched Carrier AC in one day, under one permit. The bundle saved about $1,100 in labor and trip charges. Both units are warrantied.

Problems we solve

Furnace problems we solve in Milwaukie

Most furnace replacements start with a symptom you've been ignoring for weeks. Here are the common ones we see across Milwaukie and what happens if you wait.

Ask a pro →
01

Furnace not heating or blowing cold air

We diagnose the failure same-day. If the heat exchanger is cracked, replacement is the only safe option. We install a new furnace, often the same day, and test combustion before we leave.

↗
02

Rising gas bills with no comfort gain

We run a load calculation and quote a 96% AFUE furnace that cuts gas use 15-20%. Most Milwaukie homeowners see the upgrade pay for itself in 6-9 heating seasons.

↗
03

Frequent breakdowns and repair calls

We give you both numbers: repair cost versus replacement cost. If repair makes sense, we do it. If not, we quote a new furnace with a 10-year parts warranty and a 5-year labor warranty.

↗
04

Uneven heating room to room

We seal accessible ductwork and balance airflow during the furnace install. Rooms in Linwood and Hector Campbell that never warmed up finally do. No more space heaters.
