AC Evaporator Coil Replacement in Spokane, WA
The evaporator coil sits inside your air handler and absorbs heat from your home's air as refrigerant passes through it. When the coil corrodes, cracks, or develops a refrigerant leak, the system loses its ability to cool effectively. Evaporator coil replacement is an involved job — it requires pulling the air handler apart and recovering refrigerant. It's not a quick fix, but it's often the right one when the coil is truly failed.

How It Works
Our Process for AC Evaporator Coil Replacement
- 1
Leak Confirmation
We verify the leak is at the evaporator coil and not at a nearby fitting or valve before opening the air handler.
- 2
Refrigerant Recovery and Coil Removal
We recover refrigerant, disconnect the lines, and remove the failed coil from the air handler — this takes time to do right.
- 3
New Coil Installation
We install the correct replacement coil, braze the refrigerant connections, and pressure test before pulling a vacuum on the system.
- 4
Recharge and Airflow Check
After recharging to spec, we check temperature split across the coil and verify airflow is adequate before closing the system up.
Spokane Context
Why this matters in Spokane
Spokane homes with older air handlers — especially those installed during the housing booms of the 1990s and early 2000s — are hitting the point where evaporator coil corrosion is becoming a real issue. Formicary corrosion from household chemicals and copper coils is something we see regularly.
Straight Talk
About pricing & scope
Cost varies based on the coil model your air handler requires and how accessible the unit is in your home. Attic installations take longer than utility closet setups, and that affects labor.
