Trane 5TTR7048A1000A – 4 Ton 17 SEER2 Multi-Speed Air Conditioner with ComfortSeek™

Experience powerful, energy-efficient cooling with the Trane 5TTR7048A1000A, a 4-ton multi-speed air conditioner engineered with ComfortSeek™ inverter technology for enhanced residential comfort and performance. As part of Trane’s 5TTR70 series platform, this R-454B system features an inverter-driven scroll compressor, variable-speed outdoor fan, and Spine Fin™ coil for precise temperature control and long-term durability 

Inverter-Driven Scroll Compressor with Multi-Speed Operation
The 5TTR7048A1000A utilizes a single inverter scroll compressor with multi-speed operation (1 – Multi configuration) operating on 208/230V, 1-phase, 60 Hz power. Minimum Branch Circuit Ampacity is 33 amps with recommended/max breaker ratings of 35/50 amps. The inverter drive modulates capacity to match load demand, improving efficiency, humidity control, and overall comfort consistency 

4 Ton Cooling Capacity with 17 SEER2 Platform
Model nomenclature identifies this unit as a 4-ton system (48 = 48,000 BTU nominal capacity) within the 17 SEER2 product family. The unit is certified in accordance with AHRI Standard 210/240 and rated under AHRI Standard 270/275 for verified cooling and sound performance 

Variable-Speed Direct-Drive Outdoor Fan
The outdoor fan features a 27.5-inch propeller with a direct-drive variable-speed motor (1 – 1/2 HP). Operating between approximately 600–1050 RPM, the fan adjusts airflow based on system demand. Full load amps are rated at 2.3, supporting responsive condenser performance under varying cooling loads 

Spine Fin™ All-Aluminum Outdoor Coil
The outdoor coil incorporates Trane’s patented Spine Fin™ design with 1 row at 24 FPI and 27.87 sq. ft. of face area. The 3/8-inch tube construction enhances heat transfer efficiency while the all-aluminum design and louvered panels protect against corrosion and outdoor elements 

R-454B Refrigerant & Charging Specifications
The 5TTR7048A1000A utilizes R-454B refrigerant with an approximate factory charge of 7 lb, 1 oz. Rated line sizes include 7/8" O.D. gas and 5/16" O.D. liquid connections. Charging specification is 12°F subcooling for proper system setup 

Quiet Multi-Speed Operation with AHRI-Rated Sound Performance
Under AHRI Standard 270 test conditions, the 5TTR7048A delivers an A-weighted sound power level of 70 dB(A) at minimum speed and 75 dB(A) at maximum speed in cooling mode, helping maintain controlled outdoor sound levels even during high-capacity operation 

Durable Weather-Resistant Cabinet Construction
The cabinet is constructed of heavy-gauge G60 galvanized steel with weather-resistant powder paint on louvered panels and a corrosion-resistant CMBP-G30 DuraTuff™ base. This rugged construction supports long-term durability in outdoor installations 

Operating Range & Built-In Freeze Protection
Designed to operate in cooling at outdoor ambient temperatures from 55°F to 120°F, the system includes built-in freeze protection. When operating below 55°F, capacity is reduced or the system cycles off to prevent operation under adverse conditions 

Engineered for Larger Residential Cooling Loads
Ideal for larger homes and higher heat gain applications, the Trane 5TTR7048A1000A delivers 17 SEER2 multi-speed performance, inverter-driven efficiency, variable-speed airflow control, and Spine Fin™ durability in a 4-ton outdoor air conditioning platform built for precise comfort and long-term reliability.
