AC Evaporator Coil Replacement Service in Arlington, TX
The evaporator coil sits inside your air handler and absorbs heat from your home's air as refrigerant passes through it. When it develops a leak, refrigerant escapes and the system loses cooling capacity progressively until it stops working. Coil leaks are usually caused by formicary corrosion — a reaction between copper tubing, moisture, and household chemicals. Replacing the coil is a significant repair, but continuing to add refrigerant to a leaking coil is a short-term fix that costs more over time.

When to Call
When You Need AC Evaporator Coil Replacement Service
- A technician confirmed a slow refrigerant leak at the indoor coil through leak detection

- Your air handler is original to a home built before 2010 and refrigerant is low again
How It Works
Our Process for AC Evaporator Coil Replacement Service
- 1
Leak Confirmation
We use electronic leak detection and UV dye tracing to confirm the evaporator coil is the leak source, not the lineset or fittings.
- 2
Refrigerant Recovery
All remaining refrigerant is recovered into a certified recovery cylinder before the system is opened — it doesn't get vented.
- 3
Coil Replacement
The old coil is removed, the new factory-matched coil is installed, and all connections are brazed and pressure-tested before recharging.
- 4
Recharge and Verify
We recharge to manufacturer spec by weight, then verify superheat and subcooling readings confirm the system is operating correctly.
Arlington Context
Why this matters in Arlington
Arlington homes built in the late 1990s and 2000s have air handlers reaching the end of their typical coil lifespan now. Formicary corrosion accelerates in homes where cleaning products, paint, or adhesives are used regularly indoors.
Straight Talk
About pricing & scope
Cost depends on coil size, refrigerant type, and whether the replacement coil must be special-ordered. Homes still using R-22 refrigerant face higher material costs due to that refrigerant's limited availability.
