3 Ton EcoTemp 15.5 SEER2 R454B Central System W5A5S36AKDWA, WCHL365AB
This EcoTemp system pairs the W5A5S36AKDWA single-stage condenser with the WCHL365AB multipoise ECM air handler, AHRI certified at 15.5 SEER2 (#217423600). 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 20 kW available.
Is a 3 Ton Air Conditioning System the Right Size?
A 3 ton system is often used in 3-bedroom homes around 1,500–1,800 sq. ft. as a general guide. Hot, humid climates may need more capacity.
At 3 tons, return air sizing often decides whether the system delivers its rated capacity. Pair a Manual J load calculation with a duct check.
Ideal for: 3-bedroom single-family homes, larger townhomes and manufactured homes.
Want higher efficiency? See the 3 Ton EcoTemp 16 SEER2 R454B Central System W5A5S36AKDWA, WCHL425AC, which pairs the same condenser with a larger air handler.
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.

Frequently Asked Questions
How is this system different from the 16 SEER2 3 ton EcoTemp?
Both use the W5A5S36AKDWA condenser. This system pairs it with the matching 3 ton WCHL365AB for 15.5 SEER2, while the 16 SEER2 version uses the larger 21-1/8" wide WCHL425AC.
How big is the WCHL365AB?
It's 49-5/8" tall, 17-5/8" wide and 22-1/16" deep and ships at 148 lbs, with a 1/2 HP ECM motor rated for 1,050 CFM.
What subcooling target does the 3 ton condenser use?
The spec sheet lists 8°F required subcooling for the 36 size with the indoor TXV.
Is there a 3 ton EcoTemp heat pump system?
Yes. The 3 Ton EcoTemp 14.5 SEER2 R454B Heat Pump System W5H5S36AKAAA, WCHL365AB uses the same air handler and adds heating from the outdoor unit.
What electrical service does the 3 ton W5A5S condenser require?
The spec sheet lists 17.6 minimum circuit amps and a 30 amp maximum time-delay fuse or breaker at 208/230V single phase.
How much service clearance does the WCHL365AB need?
EcoTemp calls for 21" of clearance in front of the air handler for service access.
