Bill Scott's Heating & Air Conditioning | Certified HVAC Repair in Austin, TX

In Austin's humidity, a frozen evaporator coil is often caused by restricted airflow or low refrigerant. Dirty air filters, closed vents, or a failing blower motor can reduce airflow, causing the coil to get too cold and freeze. Low refrigerant from a leak has the same effect. Our technicians will check your filter, airflow, and refrigerant levels to diagnose and fix the root cause, preventing future freeze-ups.

Warning signs include weak airflow from your vents, unusual humming or screeching noises from the indoor unit, the system frequently tripping its circuit breaker, or a complete lack of air circulation. Since the blower motor is crucial for both cooling and heating, a failure will stop your system completely. We recommend calling us at the first sign of trouble to prevent a total breakdown, especially during Austin's peak summer heat.

Absolutely. Our preventative maintenance service is specifically tailored to combat issues like blower motor strain and coil freeze-ups. We thoroughly clean system components, check electrical connections, verify refrigerant levels, ensure proper airflow, and lubricate moving parts. This proactive care reduces wear and tear, improves efficiency, and helps catch small problems before they lead to a major repair, saving you money and discomfort.
