White Vernon Heating & Cooling - Rolla's Expert HVAC Repair

This is a classic sign of an evaporator coil freeze-up, a common issue in Rolla due to our humidity and system strain. It's often caused by low refrigerant, a dirty air filter, or a failing blower motor. The ice blocks airflow, making the problem worse. Turn the system off to let it thaw, and call us. Our technicians will diagnose the root cause, fix the leak or blockage, and get your cool air flowing again safely and efficiently.

An outdoor fan motor failure means your AC can't expel heat, causing the system to overheat and shut down. First, check your circuit breaker. If it's not tripped, the issue is likely a faulty capacitor or motor. Continuing to run it can cause severe damage. Give White Vernon a call. We'll troubleshoot the electrical components, replace the failed part with a high-quality replacement, and get your unit back to cooling your Rolla home reliably.

Proactive maintenance is key. We recommend bi-annual tune-ups—once before summer and once before winter. Our service includes cleaning coils, checking refrigerant levels, testing electrical components, and lubricating motors. This helps prevent the freeze-ups and motor failures we often see locally. A well-maintained system runs more efficiently, lasts longer, and is less likely to break down on the hottest or coldest days. Ask us about our affordable maintenance plans for year-round peace of mind.
