When it is time to cool a medium-to-large home (up to 2,500 square feet), you need an outdoor system built for absolute reliability and efficiency. The Trane XR16 4 Ton Air Conditioner Condenser (4TTR6048N1000) delivers 48,000 BTU of premium cooling power. Operating as a highly dependable single-stage system, this heavy-duty AC unit achieves an impressive 16.2 SEER2 efficiency rating. This means it aggressively cools your home while utilizing significantly less electricity than older, legacy systems, resulting in noticeable summer utility savings.
Trane designs the XR16 series to survive the harshest outdoor environments. Rather than using generic parts, this unit features proprietary Trane engineering—from the all-aluminum Spine Fin™ coil to the rust-proof composite base pan. The result is a cooling system that resists weather, yard hazards, and internal wear to provide years of uninterrupted comfort.

- DuraTuff™ Non-Corrosive Base Pan: Manufactured from an advanced composite material that will never warp, crack, or rust over the lifespan of the condenser.
- Weatherguard™ Fasteners: Zinc-coated, corrosion-resistant fasteners secure the cabinet, preventing unsightly exterior rust streaks from bleeding down the unit.
