Finding the Right HVAC Part


Match the manufacturer, part number, revision, and voltage from your unit's nameplate or existing part. Many HVAC boards have revision letters that matter, so double-check before you order. For help, email sales@hillcountryliquidators.com or call 210-632-2018.

Why Technicians Buy Surplus HVAC Parts

OEM boards and controls can be expensive and hard to get for older units. Surplus parts help contractors complete repairs at a lower cost and keep customers cooling or refrigerating without a long wait.
