5 Ton EcoTemp 15 SEER2 110K BTU Single Stage Gas System W5A5S60AKAWA, W5AM61M21XA, WFER110C060C
Five tons of residential cooling at 15 SEER2, which is the highest efficiency rating of any 4 or 5 ton system in the EcoTemp gas range. The W5A5S60AKAWA condenser delivers 60,000 BTU/h of R-454B cooling from a two-row, nine-circuit coil and is the only unit in the series with a 1-1/8 inch vapor connection. It pairs with the W5AM61M21XA cased coil on the 21-inch cabinet and the five-burner WFER110C060C furnace at 110,000 BTU/h input and 90,000 BTU/h output, 80% AFUE, whose 1 HP blower and 2,040 CFM rating are matched exactly to 5 ton airflow through the 060 designation. This is the configuration for 2,500 to 3,500 square foot homes, large open-plan layouts, and single-zone houses that have simply outgrown a 4 ton system.
Is a 5 Ton / 110K BTU Gas System the Right Size?
Five tons is the top of standard residential split-system capacity, and at 60,000 BTU/h of cooling it typically covers 2,500 to 3,500 square feet depending on climate and construction. Paired with 90,000 BTU/h of heat output, the balance suits moderate to cold four-season regions. Homes needing more cooling than this generally move to light commercial equipment or to two systems, which is often the better answer for large or multi-level houses where a single 5 ton system struggles to distribute air evenly.
At this capacity, duct design stops being a detail. Five tons requires roughly 2,000 CFM, which demands substantial trunk sizing, generous return grille and filter area, and enough branch runs to distribute the air without excessive velocity or noise. Many homes that calculate to a 5 ton load are better served by two smaller systems or a zoned design. Where a single 5 ton system is the right call, the 060-rated blower supplies the airflow capability required, but the ductwork has to be able to accept it.
Ideal for: Homes of roughly 2,500 to 3,500 square feet, large open-plan single-story layouts, houses with substantial existing trunk duct capacity, moderate to cold four-season climates, and 5 ton replacements where efficiency matters and a 21-inch cabinet fits.
Need more capacity? Step up to the 5 Ton EcoTemp 14.5 SEER2 135K BTU Gas System W5A5S60AKAWA, W5AM61M24XA, WFER135D060C for maximum heat output, or compare the 4 Ton EcoTemp 110K BTU Gas System W5A5S48AKAWA if the load calculation lands below 5 tons.
Recommended sizing ranges are general guidelines only. Actual system requirements depend on insulation, window area, air infiltration, duct design, occupancy, and local design temperatures. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

Two details set this system apart from everything below it. First, the 060 airflow designation on the WFER110C060C is matched precisely to 5 ton service, so the blower is neither oversized nor short. Second, the W5A5S60AKAWA steps the vapor line to 1-1/8 inch, which means a retrofit over 7/8 inch tubing from a 3.5 or 4 ton system is not a straight swap — plan for new line set from our copper line sets and fittings selection. The condenser also carries the largest factory charge in the range at 7.9 lb. Propane installations require the EcoTemp AGAGC8NPS01C LP conversion kit, available from the drop-down and sold separately.

Frequently Asked Questions
Why does the 5 ton system rate 15 SEER2 while the 4 ton rates 14.5?
Ratings depend on the specific coil and circuiting design of each capacity, not on a smooth curve. The W5A5S60AKAWA uses a two-row coil with nine refrigerant circuits and the largest factory charge in the series at 7.9 lb, and matched to the W5AM61M21XA coil it certifies at 15 SEER2 under AHRI 215197310. The 4 ton unit uses an eight-circuit coil and rates 14.5 SEER2.
Why does this condenser use a 1-1/8 inch vapor line?
Refrigerant mass flow at 5 tons is high enough that a 7/8 inch suction line would create excessive pressure drop and velocity, costing capacity and risking poor oil return. Stepping to 1-1/8 inch keeps both within design limits. It is the only unit in this range with that connection size, so retrofits from smaller equipment need new tubing rather than reuse.
Is 90,000 BTU of heat output enough behind 5 tons of cooling?
For a large home in a moderate climate, generally yes — 90,000 BTU/h of output serves a substantial house where winters are not severe. In cold climates, a home needing 5 tons of cooling often needs more than 90,000 BTU/h of heat, which is why the 132,000 BTU/h input version exists on the wider 24-1/2 inch cabinet. A heating load calculation at design temperature is what separates the two.
What is the W5AM61M21XA coil, and why is it numbered 61?
In W5AM nomenclature the digits after the series letters indicate the capacity code, and 60 through 62 designate 5 ton coils — so 61 is a 5 ton coil. The M21 that follows indicates the 21-inch nominal cabinet width, and the X denotes a factory-installed TXV. Its airflow range of 1,500 to 2,500 CFM brackets the roughly 2,000 CFM a 5 ton system requires.
Does a 5 ton system need a 50 amp circuit?
The W5A5S60AKAWA lists a minimum circuit ampacity of 31.1 amps and a maximum fuse or breaker rating of 50 amps. A 50 amp circuit satisfies it comfortably; a smaller circuit may also be acceptable if conductors meet the MCA. Size conductors, disconnect, and overcurrent protection from the installation instructions and local electrical code rather than from the previous equipment.
What are the most common applications for a 5 ton residential system?
Large single-story homes with open floor plans, houses of 2,500 to 3,500 square feet on a single zone, homes with extensive glazing or high ceilings, and light commercial spaces such as small offices, retail suites, and community rooms. Above this capacity the equipment class changes; see our straight cool 3 to 20 ton systems for light commercial options.
