5 Ton EcoTemp 14.5 SEER2 R-454B Heat Pump System – W5H5S60AKAAA & WCHL605BD
The EcoTemp W5H5S60AKAAA and WCHL605BD are the top of this R-454B heat pump line. They deliver 60,000 BTU/h of heating and cooling at 14.5 SEER2 for the largest residential loads. The outdoor unit has its own larger 35" cabinet. The two-piece modular WCHL605BD air handler moves 1,750 CFM nominal and can be carried in sections into attics and crawlspaces.
Is a 5 Ton Heat Pump System the Right Size?
Five tons is the top of the typical residential range. Choose it only when a load calculation shows demand near 60,000 BTU/h, which is common in large homes, open floor plans and high-glass designs. Oversizing a single-stage system this large hurts humidity control, so verify with our tonnage and BTU calculator and a Manual J.
Ducts must handle about 1,750 CFM, and the electrical service must support the outdoor unit plus any large heat strip. This listing offers heat strips from 5 to 20 kW.
Ideal for: Large single-family homes, open-concept and vaulted floor plans, high-load homes, and replacement of existing 5 ton heat pump systems.
Prefer cooling only? Compare the 5 Ton EcoTemp 15.5 SEER2 W5A5S60AKAWA & WCHL605BD Central System, which uses the same air handler with an R-454B air conditioner.
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.

Frequently Asked Questions
Can a 7/8" line set be used instead of 1-1/8" on the 5 ton?
Yes. The W5H5S60AKAAA is rated with 1-1/8", but 7/8" is an acceptable vapor diameter, with 0% cooling capacity loss at 26–50 ft and 1% at 51–80 ft per the spec sheet. 7/8" x 3/8" line sets are offered with this listing.
What is the benefit of the modular WCHL605BD design?
The WCHL605BD comes in two pieces, which makes it easier to carry through attic openings and crawlspace access points before assembly.
How much vertical separation is allowed if the 5 ton unit sits below the air handler?
For the 60 size, total equivalent length is limited to 190 ft at 31–40 ft of separation, 150 ft at 41–50 ft and 110 ft at 51–60 ft. Separation beyond 60 ft is outside the acceptable range.
What pad size does the W5H5S60AKAAA need?
The spec sheet lists a 35" minimum ground-mount pad dimension for the 60 size, larger than the 31-3/16" pad used by the 1.5 to 4 ton models.
What electrical service does the 5 ton outdoor unit need?
The W5H5S60AKAAA requires 31.1 MCA and a 50 amp max time-delay fuse or HACR breaker. The air handler needs a separate circuit sized for the heat strip.
Is there a cooling-only version of this 5 ton EcoTemp system?
Yes. The 5 Ton EcoTemp W5A5S60AKAWA & WCHL605BD Central System pairs the same air handler with a 15.5 SEER2 R-454B air conditioner.
