2 Ton EcoTemp 16 SEER2 R454B Central System W5A5S24AKAWA, WCHL245AB
This EcoTemp system pairs the W5A5S24AKAWA single-stage condenser with the WCHL245AB multipoise ECM air handler, AHRI certified at 16 SEER2 (#214878128). It runs on R-454B, a low-GWP A2L refrigerant, and the air handler has a refrigerant leak detection and dissipation system and a factory-installed TXV. It's cooling only, with electric heat kits from 5 kW up to 15 kW available.
Is a 2 Ton Air Conditioning System the Right Size?
A 2 ton system commonly fits 2-bedroom homes and larger condos around 1,000–1,300 sq. ft. as a general guide.
Sun exposure, ceiling height and insulation can shift that range in either direction. A Manual J load calculation gives the real answer.
Ideal for: 2-bedroom homes, larger condos, townhomes and manufactured homes.
Need more capacity? Step up to the 2.5 Ton EcoTemp 15.5 SEER2 R454B Central System W5A5S30AKAWA, WCHL305AB for a larger load.
Recommended home sizes are general guidelines only. Actual system requirements depend on insulation, climate, windows, ductwork, occupancy and a proper load calculation. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.
