Full system diagnostic
We test refrigerant charge with manifold gauges, check electrical components with a clamp meter, and inspect the blower motor, capacitors, and contactors. You get a clear explanation of what failed and why.
When your furnace quits on a 28-degree night or your AC blows warm air in July, you need HVAC repair near me Milwaukie OR that shows up fast.

HVAC repair near me Milwaukie OR is the diagnostic and repair work that gets your heating, cooling, or ventilation system running again after a breakdown, strange noise, or temperature failure. That means tracing the fault with manifold gauges and a multimeter, checking refrigerant charge on your R-410A or R-22 system, testing capacitors and contactors, and confirming your blower motor is moving the right CFM. We repair Carrier, Trane, Lennox, Goodman, Rheem, York, Mitsubishi Electric, and Daikin equipment, and we work on Nest and Ecobee thermostats too.
Milwaukie homes take a beating from wet winters and hot, dry summers. Furnaces that sat idle since March often fail on the first cold snap, and AC units that ran through August develop refrigerant leaks or frozen evaporator coils. When you search Milwaukie OR HVAC repair near me, you want a tech who knows this climate. We also clear clogged condensate drains, replace dirty air filters, and repair duct leakage that wastes 20 to 30 percent of your conditioned air.
Every repair visit starts with a full diagnostic and ends with a tested, running system. Here is what is covered in a standard call, and what we quote separately if your job needs it.
We test refrigerant charge with manifold gauges, check electrical components with a clamp meter, and inspect the blower motor, capacitors, and contactors. You get a clear explanation of what failed and why.
Capacitors, contactors, igniters, flame sensors, thermostats, and blower motors are stocked on our vans. Most replacements finish the same visit, usually within 1 to 3 hours of arrival.
We locate leaks with an electronic detector, repair the line or fitting, then recharge your R-410A or R-22 system to factory spec. We verify the charge with gauges before we leave.
Clogged condensate drains and dirty filters cause a large share of no-cool calls. We clear the PVC line, check the drain pan, and confirm airflow so the system runs at the right CFM.
We run the system through a full heating or cooling cycle and record supply and return temperatures. You see the numbers that prove the repair worked before we pack up.
You call (855) 947-9500 and tell us what is happening: no heat, no cool, weird noise, water on the floor. We ask a few quick questions to figure out whether this is a repair or an emergency, then book a same-day window that fits your schedule.
A NATE-certified tech arrives in a stocked van, typically within 2 to 4 hours. He runs a full diagnostic with manifold gauges, a clamp meter, and a leak detector, then shows you exactly what failed and what it costs to fix. You approve before any work starts.
Most repairs take 1 to 3 hours. We replace the failed capacitor, contactor, blower motor, or refrigerant charge, then run the system through a full heating and cooling cycle to confirm temperatures and airflow hit spec. We clean up and haul away old parts.
Before we leave, we walk you through what we fixed and show you the readings. We check your air filter, note the size you need, and point out anything else that looks worn. You get a written summary of the work and the parts we installed.

Used to read high-side and low-side refrigerant pressures on R-410A and R-22 systems. The readings tell us whether the charge is correct or whether there is a leak.
Pinpoints refrigerant leaks at fittings, Schrader valves, and coil joints. Finding the leak first prevents us from recharging a system that will just leak again.
Tests capacitors, contactors, and blower motor amp draw. These readings confirm whether a component has failed or whether the problem is upstream in the control board.
Used when a repair requires opening the refrigerant circuit. The recovery machine captures refrigerant per EPA rules, and the vacuum pump pulls the system down before recharging.
Straightens bent condenser fins and clears debris from ductwork. Both improve airflow, which is one of the most common causes of weak heating and cooling.

A homeowner in Oak Grove woke up to a 54-degree house in late November. The furnace was running but blowing cold air. The previous company quoted a full furnace replacement at $4,800.
After: We diagnosed a failed hot surface igniter and a dirty flame sensor. Both parts were on the van. Total repair: $310, completed in 90 minutes. The furnace fired and held 68 degrees through the night.

An Ardenwald homeowner's AC ran constantly but the house would not drop below 79 degrees in August. The system was 6 years old and low on R-410A, but nobody had found the leak.
After: We located a leaking Schrader valve with an electronic detector, replaced the valve, pulled a vacuum, and recharged the system to factory spec. Supply air dropped from 68 to 55 degrees. The repair cost $540.
