Frozen AC Unit Repair in Plano, TX
A frozen AC unit happens when refrigerant or airflow problems cause the evaporator coil to drop below freezing, coating itself in ice and blocking all cooling. Running the system harder does not help — it makes the freeze worse. The ice itself is just a symptom. The real cause is usually low refrigerant from a leak, a dirty filter restricting airflow, or a failing blower motor that can't move enough air across the coil. We find the cause, not just thaw the coil.

When to Call
When You Need Frozen AC Unit Repair
- You can see ice on the refrigerant lines coming out of your indoor unit

- You noticed water pooling around your indoor air handler after the system ran during peak afternoon heat
- Your system works fine in the morning but freezes up every afternoon during Plano's hottest weeks
How It Works
Our Process for Frozen AC Unit Repair
- 1
Safe Shutdown and Thaw
We shut the compressor off and run the fan only to thaw the coil safely, usually one to two hours, before any diagnosis can happen.
- 2
Airflow Inspection
We check filter condition, blower motor speed, and every return grille to rule out restricted airflow as the cause before touching refrigerant.
- 3
Refrigerant and Coil Evaluation
Once the coil is clear, we check refrigerant pressure and inspect the coil for leaks, dirt buildup, or damage that would cause temperatures to drop too low.
- 4
Repair and Test Cycle
We correct the identified problem — whether a leak repair, blower fix, or coil cleaning — then run a full cooling cycle to confirm the freeze does not return.
Plano Context
Why this matters in Plano
Plano's extended 100-degree stretches in July and August push AC systems hard for weeks at a time. Units with even minor refrigerant loss that survive spring can freeze solid once ambient temperatures stay high and the system never gets a break.
Straight Talk
About pricing & scope
Cost depends on whether the cause is a simple filter or blower issue versus a refrigerant leak that requires locating, repairing, and recharging. A leak repair is more involved and more expensive than airflow correction.
