2.5 Ton EcoTemp 15.2 SEER2 45K BTU Single Stage Gas System W5A5S30AKAWA, W5AM30M14XA, WFER045A036C
This configuration exists for one specific problem: needing 2.5 tons of cooling in a home whose furnace closet was framed for something much smaller. The W5A5S30AKAWA condenser produces 30,000 BTU/h of R-454B cooling at 15.2 SEER2, and it is matched here to a W5AM30M14XA cased coil and a WFER045A036C furnace that both stay on the narrow platform, 14 inches for the coil cabinet and 14-3/16 inches for the furnace. It is the largest cooling capacity EcoTemp offers on that cabinet width. The two-burner furnace supplies 44,000 BTU/h input and 36,000 BTU/h output at 80% AFUE, so the package is aimed squarely at warm-climate homes of roughly 1,300 to 1,700 square feet that need serious air conditioning and only occasional heat. As a bonus, the W5A5S30AKAWA is the quietest condenser in this entire system range at 71 dBA.
Is a 2.5 Ton / 45K BTU Gas System the Right Size?
The cooling side is the reason to buy this package. At 30,000 BTU/h nominal it typically covers 1,300 to 1,700 square feet in hot climates with reasonable insulation, and more in a shaded, tightly built home. The heating side at 36,000 BTU/h of output is deliberately modest, which is appropriate for Florida, the Gulf Coast, south Texas, Arizona, and southern California, where the furnace may run only a few dozen hours a season. Anywhere with a real winter, this heat-to-cool ratio will come up short and the 70K version becomes the correct choice.
Sizing accuracy matters more at 2.5 tons than at the bottom of the range, because the penalty for guessing high compounds. An oversized 2.5 ton system in a 1,100 square foot house short-cycles, leaves humidity in the air, and wears the compressor with frequent starts. Cooling load is set by glazing area and orientation, attic insulation and ventilation, duct location and leakage, roof and wall color, infiltration, and internal gains, and in humid regions the latent portion of that load deserves separate attention. Confirm that existing ductwork can carry the required airflow before assuming a straight capacity increase will improve comfort.
Ideal for: Warm-climate homes of about 1,300 to 1,700 square feet, Florida and Gulf Coast slab-on-grade construction, homes with large west-facing glass, single-zone two-story layouts in the Sun Belt, and 2.5 ton replacements where the existing closet or alcove will not accept a cabinet wider than 14-3/16 inches.
Need more capacity? Step up to the 3 Ton EcoTemp 15.5 SEER2 70K BTU Gas System W5A5S36AKDWA, W5AM36M17XA, WFER070B036C, or stay at 2.5 tons and add heat with the 2.5 Ton EcoTemp 15.5 SEER2 70K BTU Gas System WFER070B036C on the wider 17-1/2 inch cabinet.
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.

The 15.2 SEER2 rating reflects this specific pairing of a 2.5 ton condenser with a 14-inch coil cabinet. Moving the same condenser to the wider W5AM30M17XA coil, as the 70K version of this system does, raises the rating to 15.5 SEER2 — a useful illustration of how much indoor coil size influences system efficiency. If cabinet width is not a constraint in your installation, that comparison is worth making before ordering. Both configurations are AHRI certified as complete matches. Propane conversion uses the EcoTemp AGAGC8NPS01C LP kit, available as a drop-down option and not included. Pair the system with a compatible control from our thermostats and controls range.

Frequently Asked Questions
Why is this system rated 15.2 SEER2 when the 2 ton version reaches 16?
Efficiency ratings belong to the complete combination, not the condenser alone. As nominal capacity rises, holding efficiency requires proportionally more indoor and outdoor coil surface. Here a 30,000 BTU condenser is paired to a coil on the narrow 14-inch cabinet, which caps the rating at 15.2 SEER2 under AHRI certificate 214964857. The same condenser on the wider 17-1/2 inch W5AM30M17XA coil rates 15.5 SEER2.
Is 2.5 tons the largest cooling capacity available on the 14-inch cabinet platform?
Yes, within this EcoTemp gas system range. Above 2.5 tons the matched coils move to the 17-1/2 inch and 21-inch cabinets, and the furnaces follow to the B, C, and D chassis. That makes this configuration the ceiling for anyone whose installation space is fixed at the narrow width, which is precisely why it gets specified for closet retrofits in larger warm-climate homes.
Which condenser in this range runs the quietest?
The W5A5S30AKAWA used here, at 71 dBA. Sound ratings across the W5A5S line run from 71 to 75 dBA, and the 2.5 ton model sits at the low end because its six-circuit coil and fan arrangement move the required heat at lower fan speed relative to cabinet size. Installation position still governs perceived noise more than the rating itself.
Will the 1,080 CFM blower support 2.5 tons of cooling airflow?
Yes. A 2.5 ton system typically calls for about 1,000 CFM at 400 CFM per ton, and the WFER045A036C blower is rated to 1,080 CFM with airflow capability certified for cooling systems up to 3 tons. Reaching that airflow in the field still depends on duct sizing, filter selection, and total external static pressure, so the blower rating is a ceiling rather than a guarantee.
Does the 2.5 ton condenser require a larger breaker than the 2 ton model?
Yes. The W5A5S30AKAWA has a minimum circuit ampacity of 16.5 amps and a maximum fuse or breaker rating of 25 amps, compared with 13.6 amps and 20 amps on the 2 ton W5A5S24AKAWA. Existing 20 amp disconnects and conductors sized for a smaller unit will need review against the installation instructions and local code before reuse.
Can the furnace be installed in a garage or other unconditioned space?
Garage and attic installations are common for multi-position furnaces like this one, subject to the clearance, combustion air, venting, and ignition-source elevation requirements in the WFER installation instructions and local code. Unconditioned locations also raise the importance of duct insulation and sealing, since duct losses in a hot attic or garage can erode a meaningful share of the system's rated efficiency.
