Customer Success Story: Frozen A/C System Resolved | AC repair Irving, TX

📍 Location: Irving, TX
🏠 Service: HVAC Repair – Frozen A/C System
An Irving homeowner reached out after noticing their A/C system was iced up and not cooling properly. The issue had created discomfort and concern during peak usage hours. Our technician responded quickly and diagnosed two key problems:
• Malfunctioning indoor blower motor
• A faulty zone damper motor, restricting airflow to key parts of the home
🧊 What Causes a Frozen A/C System?
Freezing can happen due to multiple reasons, typically falling into three categories:
1. Airflow Issues: Dirty filters, blower failure, blocked ducts, bad dampers, or a dirty evaporator coil
2. Refrigeration Problems: Low refrigerant, clogged filter dryer, or restricted metering device
3. Heat Load Imbalance: Operating in low ambient temps or running too cold indoors
In this case, restricted airflow from the failed blower and malfunctioning damper caused ice buildup on the coil and poor cooling performance.
🛠 Our Solution:
• Replaced the damaged blower motor
• Repaired the faulty zone damper
• Fully defrosted the system and verified normal operation


✅ The Result:
• Strong airflow restored
• Coil thawed and cooling efficiently
• Homeowner relieved and comfortable again
