Trane COM7074 Compressor

The Trane COM7074 is a professional-grade 0.75 ton rotary compressor engineered for high-efficiency cooling in light residential and commercial applications. Operating at 230V single phase (208-230V/1Ph/60Hz), this OEM Trane rotary compressor is the standardized replacement for decentralized splits and packaged heat pump units requiring precise refrigerant management. Built for stable performance across a temperature range of -23.3°C to 12.8°C, the COM7074 features a compact footprint and 24.5-lb chassis, making it a drop-in solution for aging HVAC infrastructure. As a genuine HVAC replacement part, it ensures proper oil return and thermal protection within the sealed system, maintaining the integrity of the original equipment's SEER rating. This rotary refrigeration compressor is designed for technicians who demand high torque and quiet operation in tight installs.

Key Benefits:

• OEM Precision: Genuine Trane COM7074 ensures exact physical and electrical compatibility with existing line sets.
• Optimized Efficiency: High-efficiency rotary design reduces amp draw during peak cooling loads.
• Durable Construction: Engineered to withstand harsh cycling in vertical or horizontal airflow configurations.
• Direct Replacement: Simplifies field installation with standard 208-230V single-phase wiring patterns.

Common Questions:

What refrigerant is the Trane COM7074 compatible with?
This compressor is typically utilized in systems using R-22 or compatible modern drop-in replacements, depending on the original system's lubricant specs and expansion valve settings. Always verify oil compatibility before charging.

Can I use this compressor for a 1-ton system?
No, the COM7074 is rated strictly for 0.75-ton (9,000 BTU) capacity. Under-sizing a compressor will lead to evaporator freezing and premature motor failure.

What are the electrical requirements for installation?
It requires a 208-230V, 60Hz, single-phase power supply. Technicians should verify capacitor ratings and contactor condition during replacement to ensure optimal startup torque.
