HVAC Repair Blacksburg VA | Call Commonwealth Heating & Air Conditioning

A failed air handler fan is a common issue here, often due to a faulty capacitor, motor, or accumulated debris. First, check your circuit breaker and air filter. If those are fine, it's best to call a professional. Our technicians can quickly diagnose the problem—whether it's a simple part replacement or a sign of a larger issue—to restore airflow and prevent further strain on your HVAC system.

This is frequently caused by a stuck or failing reversing valve, a critical component for mode switching. In our area, valve issues can stem from refrigerant problems, electrical faults, or wear from frequent cycling. Don't force the system. Our experts can test the valve and its controls, performing a precise repair or replacement to restore your heat pump's proper function for our region's seasonal temperature swings.

Proactive maintenance is key. We recommend twice-yearly tune-ups. Before cooling season, we'll clean the air handler, check fan motors and capacitors, and ensure proper airflow. Before heating season, we'll inspect the heat pump's reversing valve operation, check refrigerant levels, and clean coils. This local-focused service helps catch small issues before they lead to major failures, saving you money and discomfort.
