2 Ton EcoTemp 15.2 SEER2 R-454B Heat Pump System – W5H5S24AKAAA & WCHL245AB
The 2 ton EcoTemp pairing has the highest efficiency rating in this heat pump line: 15.2 SEER2 from the W5H5S24AKAAA outdoor unit and WCHL245AB ECM air handler. It delivers 24,000 BTU/h of R-454B heating and cooling with a 71 dBA outdoor sound rating. It suits homeowners in smaller houses, townhomes and additions who want lower operating costs without moving to a multi-stage system.
Is a 2 Ton Heat Pump System the Right Size?
Two tons, or about 24,000 BTU/h, fits many townhomes, smaller ranch homes and well-insulated additions. Heat gain through windows, attic temperature and duct losses matter as much as square footage, so start with our tonnage and BTU calculator and confirm with a load calculation.
The WCHL245AB is rated at 700 CFM nominal and uses a 1/3 HP multi-tap ECM blower, so the installer can choose a speed tap that matches the duct system's static pressure. For colder months, backup heat strips of 5, 8 or 10 kW are offered with this system.
Ideal for: Townhomes, smaller single-family homes, additions and efficiency-focused buyers needing about 24,000 BTU/h of heating and cooling.
Need more capacity? Step up to the 2.5 Ton EcoTemp W5H5S30AKAAA & WCHL305AB Heat Pump System for homes requiring additional heating and cooling capacity.
Recommended applications are general guidelines only. Actual system requirements depend on insulation, climate, duct design, window load, occupancy and desired indoor temperature. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.
