What's included
What is included in an HVAC replacement
Every replacement quote we write covers the equipment, the labor, the permit, and the cleanup. Add-ons like duct sealing or a smart thermostat are priced separately so you can see exactly what you are paying for.
Oregon CCB permit
We pull the mechanical permit and schedule the inspection. You do not have to call the city or chase paperwork. The permit is included in the quoted price.
Refrigerant recovery and disposal
Old R-22 or R-410A refrigerant is recovered with an EPA-compliant recovery machine, not vented. We haul away the old equipment and dispose of it properly.
Thermostat wiring and setup
Standard thermostat wiring is included. If you want a Nest or Ecobee, we install and configure it during the visit so scheduling and humidity control work from day one.
Commissioning and airflow check
We measure temperature split, static pressure, and gas pressure before we leave. If airflow is off, we adjust the blower speed or recommend duct fixes on the spot.
1-year workmanship warranty
Our labor is warrantied for one year on top of the manufacturer parts warranty. If something we installed fails, we come back and fix it, no trip charge.
How it works
Our HVAC replacement process, step by step
We ask the age, brand, and symptoms of your current system, plus your address in Milwaukie. Most calls get a same-day or next-morning appointment window, usually two hours wide.
A NATE-certified tech measures your home, inspects ductwork, checks the electrical panel, and tests static pressure. This takes 45 to 60 minutes and ends with two or three equipment options at different price points.
You get a line-item quote the same day: equipment model numbers, SEER rating, labor, permit, and haul-away. No surprise add-ons later. Quotes hold for 30 days.
We arrive at 8 a.m., protect floors, recover refrigerant with a recovery machine, and pull the old unit. New equipment is set, copper tubing brazed, PVC condensate line run, and the system charged by weight per the data plate.
We verify temperature split, static pressure, and gas pressure, then walk you through the thermostat. Total install time is typically 6 to 10 hours for a furnace and AC combo.

Tools & methods
Tools and methods we use on every install
Manifold gauges
Used to read suction and liquid pressures during charging so the system is set to the manufacturer's target superheat and subcool.
Vacuum pump and recovery machine
We pull a deep vacuum on the new line set before charging and recover old refrigerant from the unit being removed, per EPA Section 608.
Leak detector and multimeter
Electronic leak detection finds refrigerant leaks, and a multimeter tests capacitors, contactors, and control boards before we condemn a part.
Clamp meter
We measure amp draw on the compressor and blower motor to confirm the new equipment is running within its rated range, not just turning on.
Tube bender and fin comb
Clean copper bends on the new line set and straightened condenser fins keep airflow and efficiency where the spec sheet says it should be.
Duct cleaning vacuum
When ducts are visibly loaded with debris, we vacuum them before the new system goes in so the blower motor and air filter are not fighting the mess.
Real results
Before and after.
hvac replacement
1998 furnace and AC in Hector Campbell
A 1998 gas furnace and 10-SEER AC ran nonstop in August and struggled below 30 degrees in winter. The homeowner was paying $310 a month in combined gas and electric during peak months.
After: We installed a 96 percent AFUE furnace and 16-SEER2 AC with a new line set and sealed return. Peak-month bills dropped to about $215, and the house holds temperature within 2 degrees.

R-22 heat pump swap in Lake Road
A 2004 heat pump with an R-22 leak needed $480 in refrigerant to get through the season, and the compressor was drawing above its rated amps. The homeowner was facing a second recharge within a year.
After: We replaced it with a Mitsubishi Electric cold-climate heat pump, recovered the old refrigerant, and ran a new line set. Winter heating costs dropped roughly 30 percent, and the Oregon Energy Trust rebate covered part of the install.

Duct sealing plus new AC in Ardenwald
A 1,600 sq ft ranch had a 12-year-old AC that could not cool the back bedrooms below 78 degrees. Static pressure tested high, and accessible ductwork showed visible leakage at joints.
After: We installed a 2-ton 16-SEER2 AC, sealed the accessible sheet metal ductwork, and rebalanced registers. Back bedrooms now sit within 2 degrees of the thermostat, and the system runs shorter cycles.

Problems a new system solves in Milwaukie
Most replacements start with a symptom you have been tolerating for months. Here are the ones we hear most on the phone.
Ask a pro →AC not cooling on a 95-degree August afternoon
We test refrigerant charge, capacitors, and contactors first. If the compressor is done or the system is R-22, we quote a replacement and can often install within 48 hours.
Furnace not heating in a January cold snap
We diagnose ignition, flame sensor, and heat exchanger on the first visit. If the exchanger is cracked, we shut the gas off and quote a replacement that day.
Refrigerant leak that keeps coming back
We use an electronic leak detector to find the source. If repairs exceed $1,200 or the system is over 15 years old, replacement is the honest answer and we say so.
Duct leakage wasting half your conditioned air
We test static pressure and inspect accessible ductwork during the assessment. Sealing and repairing sheet metal ductwork is quoted alongside the replacement so the new system actually delivers.
