Trane COM13118 Compressor

The Trane COM13118 Compressor is a high-efficiency 3.1-ton scroll compressor engineered specifically for 200-230V, single-phase residential and light commercial HVAC applications. This unit serves as the direct OEM replacement compressor for legacy models COM8676 and COM7036. When servicing split systems, technicians should utilize KIT18829 for proper integration; for package systems previously using COM7036, KIT18830 is required. If the application involves a heat pump, the installation of sump heater HTR15994 is necessary to manage refrigerant migration and ensure reliable startup. Built to handle R-410A pressures, this Trane replacement part features advanced internal motor protection and optimized mechanical tolerances to maintain system subcooling and superheat levels within manufacturer specifications. Whether you are performing a compressor changeout or a full system overhaul, the COM13118 provides the exact mechanical lift and volumetric efficiency required to restore original equipment performance in XR and XL series units.

• Direct OEM Fit: Eliminates piping misalignment and mounting footprint issues during field replacement.
• High Volumetric Efficiency: Optimized for low-ambient cooling and high-load heating demands.
• Internal Protection: Features robust internal pressure relief and thermal overloads to prevent motor burnout.
• Optimized for R-410A: Designed to withstand the higher operating pressures of modern refrigerants.
• Verified Compatibility: Replaces COM8676 and COM7036 across multiple Trane and American Standard platforms.

What is the direct replacement for COM8676?
The COM13118 is the primary replacement; however, split system installations require KIT18829 for a complete repair.

Can this compressor be used in a heat pump?
Yes, but you must order and install sump heater HTR15994 to prevent liquid slugging and ensure reliable operation in heating mode.

Which refrigerant is compatible with COM13118?
This compressor is specifically designed for systems utilizing R-410A refrigerant and POE oil.
