Evaporator Coil Replacement in Frisco, TX
Evaporator coil replacement is the repair for when the coil inside your air handler is leaking refrigerant, corroded through, or physically damaged beyond what any patch can hold. The evaporator coil is where refrigerant absorbs heat from your home's air — if it's compromised, the whole system's cooling capacity collapses. This is not a small job, but it's far less expensive than replacing the full system when the rest of your equipment is in decent shape. The coil has to match your system's tonnage and refrigerant type exactly.

When to Call
When You Need Evaporator Coil Replacement
- A technician found formicary corrosion pitting your evaporator coil and refrigerant is escaping from multiple points

- You replaced your outdoor unit but the old evaporator coil inside is mismatched and inefficient
- The evaporator coil froze solid repeatedly this summer and cleaning revealed collapsed fins and cracking
How It Works
Our Process for Evaporator Coil Replacement
- 1
System Evacuation and Refrigerant Recovery
We recover remaining refrigerant from the system legally before opening any lines — nothing gets vented into the air.
- 2
Coil Removal
We disconnect the refrigerant lines, pull the failed coil from the air handler cabinet, and inspect the drain pan and surrounding components for damage.
- 3
New Coil Installation
We install the matched replacement coil, braze the line connections, and pressure-test the entire refrigerant circuit before pulling a vacuum.
- 4
Recharge and System Startup
We recharge to the correct weight, start the system, and verify pressures and temperature differential are within spec across the full operating cycle.
Frisco Context
Why this matters in Frisco
Many Frisco homes built between 2000 and 2012 have original copper evaporator coils that are now showing formicary corrosion from household cleaning product fumes. That corrosion works from the inside out and isn't visible until refrigerant is already escaping.
Straight Talk
About pricing & scope
Coil cost depends on the tonnage, brand match requirements, and whether a cased or uncased coil fits your air handler. Lead time on some coil sizes can affect scheduling, and we'll tell you upfront if that's the case.
