A plastic condenser pad provides a lightweight but extremely durable foundation for your outdoor unit to sit on. Unlike heavy concrete, these pads are easy to maneuver during installation but are built to resist cracking and UV damage for decades. We offer several sizes, including the 18x40x4 Plastic Mounting Pad. Using a pad ensures your Central Condenser stays level, which is critical for proper oil circulation and line set longevity. It also keeps your unit out of the dirt and away from weeds that could clog the Condenser Coil. These pads are an essential part of any ground-level Single-Zone or Multi-Zone project. They are designed to absorb vibrations and stay put through all types of weather. It’s a foundational piece of equipment that every homeowner should include in their initial HVAC order.
