Genuine ActronAir Valves | Reversing Valves, Expansion Valves & Service Ports

Is your air conditioner stuck on cooling during winter or failing to chill on a hot summer day? A faulty reversing valve or Electronic Expansion Valve (EEV) is often the culprit behind a system that has lost its climate control. At National AC Parts, we supply genuine ActronAir valves and coils designed for the high-pressure demands of your Serene, ESP, or Classic series. These authentic components ensure precise refrigerant metering and reliable switching, restoring the full reverse cycle functionality of your unit. With same-day dispatch nationwide, we help you get your home’s temperature back under your command.

Valve failures—particularly 'stuck' reversing valves or blocked expansion valves—are complex repairs that require an ARC-licensed technician to open the refrigeration circuit. If your system is ageing and experiencing repetitive flow issues, the labor costs for a valve replacement can be a significant portion of a new unit's price. Now is the perfect time to explore a full system upgrade. Many new ActronAir inverter models qualify for the NSW Energy Savings Scheme (ESS), providing upfront government discounts to help you transition to a more reliable, energy-efficient system.
