Call (855) 947-9500 for a same-day quote.
Air conditioner replacement Milwaukie OR is the full removal and re-installation of your outdoor condenser, indoor evaporator coil, line set, and thermostat controls, sized to your home's actual cooling load. We start with a Manual J load calculation, then match the condenser and coil to your ductwork and electrical panel. Old R-22 refrigerant gets recovered with an EPA Section 608-certified recovery machine, and your new system is charged with R-410A. Copper tubing, a PVC condensate line, and a fresh thermostat screwdriver set for the trim plate are all part of the job.
Most Milwaukie homes were built between 1950 and 1995, and many still run the original 10 SEER unit from the 1990s. Those systems use R-22, which has been phased out, so a refrigerant leak means a replacement conversation, not a recharge. If your AC not cooling calls have turned into weekly events, a Milwaukie OR Air conditioner replacement usually costs less over five years than three repair visits. We also see clogged condensate drains and frozen evaporator coils in older Ardenwald and Hector Campbell homes where return air is undersized.
Our installed price covers the equipment, the labor, the permit, and the startup. You are not paying extra for the line set flush, the pad, or the haul-away. Here is what shows up on the invoice and what we would quote separately if your home needs it.
We measure windows, insulation, and duct sizing, then calculate the exact tonnage your Milwaukie home needs. This is included on every quote because guessing tonnage is how you end up with a short-cycling system and a humidity problem.
The condenser and indoor evaporator coil are matched to the manufacturer's spec, which keeps your warranty valid. Mismatched coils are one of the most common problems we find on competitor installs, and they cost you efficiency every summer.
We recover the old R-22 or R-410A with an EPA Section 608-certified recovery machine, pull a vacuum to 500 microns, and weigh in the new charge. Superheat and subcooling get verified with manifold gauges before we call the job done.
New copper tubing, a level composite pad, and a code-correct electrical disconnect are part of the installed price. If your existing line set passes a pressure test and matches the new refrigerant, we can reuse it and pass the savings to you.
We wire and configure your existing thermostat, or install a Nest or Ecobee if you want one. Schedules, humidity targets, and away settings are set before we leave, so you are not reading a manual the first hot night.
You get the vacuum reading, refrigerant charge, and static pressure numbers on paper. We walk you through filter size, filter schedule, and the condensate drain location so you can keep the system clean between visits.
You call (855) 947-9500 and describe what the system is doing. If it is an AC not cooling call, we ask about age, refrigerant type, and whether the unit has been recharged before. If replacement is the smarter money, we say so on that call instead of selling you a repair you will repeat next summer.
We measure square footage, window orientation, insulation, and duct size, then run a Manual J load calculation. This takes about 45 minutes and tells us the exact tonnage your Milwaukie home needs. Oversized units short-cycle and leave humidity behind, so this step is not optional.
We walk you through Carrier, Trane, Lennox, Goodman, Rheem, York, Mitsubishi Electric, and Daikin options at your price point. You get the model numbers, the SEER2 rating, and the installed price before we order anything. No surprises on the invoice.
On install day we recover the old refrigerant with an EPA Section 608-certified recovery machine, pull the condenser and coil, flush or replace the line set, and set the new equipment. A typical changeout runs 6 to 9 hours. We protect floors, haul away the old unit, and leave the pad clean.
We pull a vacuum to 500 microns, weigh in the R-410A charge, and verify superheat and subcooling with manifold gauges and a clamp meter. Then we set your thermostat, walk you through the filter schedule, and leave the startup sheet with the numbers on it.

Used to read high-side and low-side pressures and verify superheat and subcooling after the new charge is weighed in. If the numbers are off, the system is not done.
Pulls the line set and coil down to 500 microns before charging. Skipping this step leaves moisture in the system, which forms acid and kills compressors early.
Recovers R-22 or R-410A refrigerant into a certified cylinder for proper disposal. Required under EPA Section 608, and we do not vent refrigerant to atmosphere.
Tests capacitors, contactors, and control boards, and measures blower motor amp draw. These readings tell us whether a part is failing or already failed.
Finds refrigerant leaks on existing line sets and coils before we decide whether to reuse or replace them. A leak we miss becomes a callback we do not want.
Bends copper tubing without kinking it and straightens bent condenser fins. Both are small details that protect airflow and refrigerant flow.
A 1994 Carrier 10 SEER unit running on R-22, leaking about a pound of refrigerant per season. The homeowner was paying $180 per recharge and the house would not drop below 78 degrees on a 95-degree afternoon.
After: We recovered the R-22 and installed a 2.5-ton 16 SEER2 Rheem with a matched coil. The house now holds 73 degrees, and the first full-summer power bill came in $58 lower than the same month the year before.

A two-story home where the upstairs never cooled below 78 degrees. Static pressure tested at 0.9 inches of water column, well above the 0.5 target, because of a crushed return duct in the crawlspace.
After: We repaired the return, sealed the plenum, and installed a 3-ton variable-speed Daikin. Upstairs and downstairs now sit within 2 degrees, and the system ramps to a lower speed instead of cycling on and off.

A Lake Road homeowner needed to replace a failing furnace and a 17-year-old AC before listing the house. Two separate contractors quoted two separate permits and two separate duct modifications.
After: We quoted a matched furnace and coil package, pulled one permit, and installed both in a single day. The startup sheet and permit number went into the disclosure packet, and the buyer's inspection cleared with no HVAC corrections.

Ask a pro →We check the charge with manifold gauges, test the capacitor and contactor with a multimeter, and inspect the evaporator coil for frost. If the compressor is gone on a 15-year-old unit, we quote replacement instead of a repair that will not last.
We recover the R-22 with an EPA Section 608-certified machine and replace the system with R-410A equipment. A new 16 SEER2 unit uses less power and comes with a 10-year parts warranty once we register it.
We thaw the coil, clear the drain, and test static pressure to find out why it froze. If the ductwork is undersized, we correct it during the replacement so the new coil does not repeat the problem.
We test the thermostat wiring with a multimeter, verify the blower motor amp draw with a clamp meter, and check the control board. If the equipment is sound, we replace the thermostat and set the new schedule.
Most Milwaukie AC replacements run $4,800 to $9,500 installed in 2026, depending on tonnage, SEER2 rating, and whether the line set needs replacing. A basic 2-ton 14.3 SEER2 single-stage system sits near the bottom of that range. A 3-ton variable-speed heat pump with a smart thermostat lands near the top. We quote the full installed price, permit included, before we order equipment.

A standard changeout takes 6 to 9 hours, so most Milwaukie jobs are done in a single day. If we have to modify sheet metal ductwork, run a new 240-volt circuit, or replace a rotted pad, add half a day. We schedule a morning start so your system is cooling by late afternoon. You do not need to move out, and you do not need to drain anything.
Replace when the unit is 12 to 15 years old, when it still uses R-22 refrigerant, or when repairs exceed $1,500 in a single season. In Milwaukie, the best window is September through November, after the cooling load drops but before the rain sets in. That timing gets you off-season pricing and a shorter install day. If your system dies in July, we still get you cool, just at peak-season pricing.
Call (855) 947-9500 and we will size your system, quote the installed price, and schedule the changeout. Same-day quotes, 5-year workmanship warranty, and Oregon CCB-licensed installs across Clackamas County.
