Evaporator Coil Replacement in McKinney, TX
The evaporator coil sits inside your air handler or furnace cabinet and is where refrigerant absorbs heat from your indoor air. When the coil develops a leak or collapses, the system loses its ability to cool and often starts producing ice on the lines or coil itself. Evaporator coil failure is less obvious than outdoor unit problems — it usually shows up slowly as declining performance. Replacement requires opening the air handler, recovering refrigerant, and properly sealing the new coil into the system.

How It Works
Our Process for Evaporator Coil Replacement
- 1

We recover all remaining refrigerant from the system before opening any lines to the coil.
- 3
Coil Replacement
We remove the failed coil, install a matched replacement, braze connections, and seal the cabinet properly against air bypass.

Evacuation and Recharge
We pull the system to a deep vacuum to remove moisture, then recharge and verify cooling performance at the registers.
McKinney Context
Why this matters in McKinney
High humidity in McKinney during spring and summer puts heavy condensation loads on evaporator coils. Coils that run constantly in that environment are more prone to developing pinhole corrosion over time.
Straight Talk
About pricing & scope
Coil cost depends on tonnage, configuration, and brand compatibility with your air handler. If your system uses R-22, the refrigerant itself adds to the scope — we'll explain that clearly upfront.
