Full system diagnostic
We test the refrigerant circuit with manifold gauges, the control board with a multimeter, and the blower motor with a clamp meter. That takes 30 to 45 minutes and tells us exactly what failed before we quote a single part.
When you search for heating and cooling repair near me Milwaukie OR, you want a tech who shows up today, not next week. ThermexaPro serves homeowners and businesses across Milwaukie, Oregon and Clackamas County with same-day diagnostics, honest pricing, and repairs done right the first time. Whether your furnace quit at 2 a.m. or your AC is blowing warm air in July, we carry the parts and tools to fix it on the spot.

heating and cooling repair near me Milwaukie OR is a licensed diagnostic and repair service that restores furnaces, air conditioners, heat pumps, and ducted systems when they stop heating, stop cooling, or start costing you money. It is needed whenever your system short-cycles, blows lukewarm air, leaks refrigerant, or trips the breaker. A proper visit includes a full electrical and refrigerant check, not just a filter swap. We test capacitors, contactors, blower motors, and thermostat wiring with a multimeter and clamp meter before we quote a single part.
Milwaukie homes take a beating from wet winters and dry, smoky summers. Furnaces that sat idle from April to October often fail on the first cold snap, and AC units that ran fine last August can freeze up when the first 90-degree day hits. If you need Milwaukie OR heating and cooling repair, we stock R-410A refrigerant, universal capacitors, and common blower motors on every truck. That means most repairs finish in one visit, not two. We also handle 24/7 heating and cooling repair in Milwaukie when a no-heat call can't wait until morning.
Every repair visit covers a full diagnostic, the repair itself, and a post-repair test. Here is what is standard on the call versus what we quote separately, so there are no surprises when the invoice arrives.
We test the refrigerant circuit with manifold gauges, the control board with a multimeter, and the blower motor with a clamp meter. That takes 30 to 45 minutes and tells us exactly what failed before we quote a single part.
You see the price on paper before work starts. It lists the failed component, the labor, and the warranty. No hourly meter, no surprise line items, no pressure to replace a system that only needs a repair.
Our trucks carry R-410A refrigerant, capacitors, contactors, igniters, and common blower motors for Carrier, Trane, Lennox, Goodman, Rheem, and York equipment. That inventory is why most repairs finish in one visit.
After the fix, we run a full heating or cooling cycle and measure the temperature split at the register. If the system is not hitting the right numbers, we keep working until it does. You see the results before we pack up.
Every repair carries a written warranty on both the part and our labor. If the same component fails inside the warranty window, we come back and fix it at no charge. That is a real commitment, not a marketing line.
We tell you what to watch for and when to schedule the next tune-up. A pre-summer AC tune-up or winter furnace tune-up catches small problems before they turn into emergency calls on the coldest or hottest day of the year.
You call (855) 947-9500 and talk to a real dispatcher, not a call center. We ask what your system is doing, how old it is, and whether you have heat or cooling at all. That five-minute conversation lets us load the right parts before the truck rolls.
Your tech arrives in a marked van, pulls on shoe covers, and runs a full diagnostic: manifold gauges on the refrigerant circuit, a multimeter on the control board, and a clamp meter on the blower motor. Expect 30 to 45 minutes. You get the findings in plain English, not jargon.
Before any repair starts, you see a flat-rate price on paper. It lists the failed part, the labor, and the warranty. If the fix is not worth it on a 20-year-old unit, we tell you that too and quote a replacement instead. No pressure either way.
Once you approve, we make the repair. Capacitor swaps take 20 minutes; blower motor replacements run 90 minutes to two hours. After the fix, we run the system through a full heating or cooling cycle and verify the temperature split at the register before we pack up.
We show you what failed, what we replaced, and how to keep it running. You get a written warranty on parts and labor, plus a reminder for your next tune-up. If anything we touched fails inside the warranty window, you call us and we come back at no charge.

Used to read high-side and low-side refrigerant pressures on AC and heat pump systems. The pressure readings tell us whether the charge is low, high, or right where it should be.
When a repair requires opening the refrigerant circuit, we recover the existing charge with a recovery machine, then pull a deep vacuum with the vacuum pump before recharging. This is EPA Section 608 required practice.
The multimeter tests control boards, thermostats, and wiring. The clamp meter reads amp draw on the blower motor and compressor, which tells us whether a component is failing or just working harder than it should.
Electronic leak detectors find refrigerant leaks at Schrader valves, flare fittings, and coil joints. Finding the leak is the only way to fix it properly instead of just topping off the charge.
The fin comb straightens bent condenser fins to restore airflow. The duct cleaning vacuum removes debris from ductwork and returns. Both are standard on our maintenance and repair visits.
The tube bender shapes copper tubing during line-set repairs without kinking it. The thermostat screwdriver set lets us open and service Nest, Ecobee, and standard thermostat housings without stripping screws.

A homeowner in Ardenwald called at 11 p.m. in January with a furnace blowing cold air. The house had dropped to 54 degrees. The furnace was a 12-year-old Goodman with a failed igniter and a dirty flame sensor.
After: Our tech arrived at 1 a.m., replaced the igniter, cleaned the flame sensor, and verified the ignition sequence. Heat was back on within 40 minutes. The temperature split at the register read 42 degrees, right in spec.

A homeowner in Oak Grove was told by another company that their 9-year-old Trane AC needed full replacement. The system was blowing warm air and the compressor was short-cycling. The quoted replacement was over $6,000.
After: We tested the capacitor and found it reading 40 percent below rated microfarads. We replaced the capacitor, found and repaired a Schrader valve leak, and recharged the system with R-410A. Total cost was under $500, and the AC cooled the house to 72 degrees that afternoon.

A heat pump in Linwood was icing over every few hours in January, forcing the auxiliary heat strips to run constantly. The power bill had jumped by $180 in one month, and the house still felt cold.
After: We diagnosed a failed defrost control board on the Mitsubishi Electric unit. After replacing the board, the heat pump returned to normal defrost cycles and carried the heating load again. The auxiliary strips stopped running, and the next power bill dropped back to normal.
Book this service →Most no-heat and no-cool calls trace back to a handful of failures. Here are the ones we see most often in Milwaukie homes, what happens if you ignore them, and how we fix them.
Ask a pro →We test the igniter, flame sensor, and gas pressure, then replace the failed component. Most ignition repairs finish in under an hour, and we check the heat exchanger for cracks while we are in there.
We check the capacitor and contactor first, then test the refrigerant charge with manifold gauges. If there is a leak, we locate it with a leak detector, repair it, and recharge with R-410A.
We check airflow first, then test the thermostat and control board. A dirty air filter or clogged condensate drain is a quick fix. If the thermostat is malfunctioning, we can install a Nest or Ecobee while we are there.
We thaw the coil, clear the clogged condensate drain and PVC line, then find the root cause. Usually it is a dirty filter or low charge. We verify the fix with a temperature split test before we leave.
