2 Ton EcoTemp 16 SEER2 70K BTU Single Stage Gas System W5A5S24AKAWA, W5AM24M14XA, WFER070A036C
Of the four systems built on EcoTemp's narrow A-size cabinet, this one carries the most even heat-to-cool ratio. The W5A5S24AKAWA condenser delivers 24,000 BTU/h of R-454B cooling at 16 SEER2 through a tonnage-matched W5AM24M14XA cased coil, while the three-burner WFER070A036C furnace supplies 66,000 BTU/h of input and 54,000 BTU/h of output heat at 80% AFUE. Both indoor pieces still fit the tight platform: a 14-3/16 inch furnace cabinet and a 14-inch coil. That combination makes it the practical four-season choice for 1,100 to 1,500 square foot homes in the mid-Atlantic, Tennessee Valley, Ohio Valley, and Pacific Northwest, where summers demand real air conditioning and winters demand real heat, but the mechanical closet has not grown any wider.
Is a 2 Ton / 70K BTU Gas System the Right Size?
Two tons of cooling paired with 54,000 BTU/h of heating output is a ratio that works across a genuine four-season climate rather than leaning to one end. Homes that fit tend to run 1,100 to 1,500 square feet with average-to-good insulation, or somewhat less square footage if the building envelope is older. The reason to choose it over the 45K version is straightforward: if your winter design temperature drops into the teens or single digits, 36,000 BTU/h of output leaves no margin, and the furnace will run continuously on the coldest nights without holding setpoint.
Getting the sizing right means calculating both loads separately at local design conditions. Attic and wall insulation, window U-factor and solar heat gain coefficient, air leakage measured by blower door, duct location and insulation, ceiling height, and occupancy all pull the two numbers in different directions. Duct capacity deserves attention too, since the blower is rated to 1,070 CFM in cooling and needs return air path sufficient to move it at reasonable static pressure. A home that turns out to need more than 24,000 BTU/h of cooling should move up the range rather than accept an undersized outdoor unit.
Ideal for: Mid-Atlantic and Midwest homes of roughly 1,100 to 1,500 square feet, four-season climates with hot summers and genuinely cold winters, 1960s to 1990s tract housing with average insulation, two-story homes on a single zone, and any closet retrofit that needs substantial heat from a 14-3/16 inch cabinet.
Need more capacity? Step up to the 2.5 Ton EcoTemp 15.5 SEER2 70K BTU Gas System W5A5S30AKAWA, W5AM30M17XA, WFER070B036C, which adds cooling capacity on a wider 17-1/2 inch cabinet, or reduce heat with the 2 Ton EcoTemp 45K BTU Gas System WFER045A036C.
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.

This is the top of the A-cabinet group on the heating side: 66,000 BTU/h input is the largest the 14-3/16 inch chassis is offered in, and anything more requires stepping up to the 17-1/2 inch B cabinet. The tradeoff is worth understanding when planning a retrofit, because it means a closet that fits this furnace can accept the maximum heat the narrow platform provides without structural changes. All three components arrive as an AHRI-certified match under number 214913631. See the full range of matched packages on our gas furnaces and gas systems page. Propane operation requires the EcoTemp AGAGC8NPS01C LP conversion kit, selectable from the drop-down and sold separately.

Frequently Asked Questions
Why choose the 70K furnace over the 45K version on a 2 ton system?
Climate. The 45K version delivers 36,000 BTU/h of heat output, which suits mild southern winters where the furnace runs intermittently. This version delivers 54,000 BTU/h, giving the reserve needed when design temperatures fall into the teens or below. Cooling performance is identical between the two because the condenser and coil are the same, so the decision rests entirely on heating load.
How does a 66,000 BTU input furnace fit the same 14-3/16 inch cabinet as the 44,000 BTU model?
Cabinet width in the WFER series is driven primarily by blower and heat exchanger depth rather than input rating alone. The 070A model adds a third burner and a larger heat exchanger within the same A-size chassis, which is why both share the 14-3/16 inch width and near-identical blower ratings of 1,070 and 1,080 CFM. Above 66,000 BTU/h input, the series moves to the 17-1/2 inch B cabinet.
Will I need to change my existing vent pipe when replacing an older 80% furnace with this one?
The WFER070A036C is a Category I metal-vented appliance, the same classification as most older 80% AFUE furnaces, so existing metal flue and chimney connections are often reusable. Vent sizing must still be verified against the input rating and the venting tables in the installation instructions, particularly on common-vented systems shared with a water heater, where a change in furnace input can affect draft.
How does this gas system compare to a heat pump for a home this size?
A heat pump provides heating and cooling from one outdoor unit and is generally more efficient in mild weather, while this configuration uses gas combustion for heat, which holds full output regardless of outdoor temperature and typically costs less to run where natural gas is inexpensive relative to electricity. In four-season climates with established gas service, a gas furnace paired to a straight-cool condenser remains the common choice for exactly that reason.
Does a single stage system dehumidify adequately in humid climates?
A correctly sized single stage system dehumidifies well because it runs long, steady cycles that keep the coil cold and continuously condense moisture. Problems arise from oversizing, not from single stage operation: an oversized unit satisfies the thermostat quickly, short-cycles, and leaves humidity behind. Matching capacity to the calculated load is the single most effective step for humidity control.
What is not included with this system?
The package covers the condenser, cased coil, and furnace. Refrigerant line sets, thermostat, condensate pump or drain materials, electrical disconnect and wiring, equipment pad, flue and gas piping, and the LP conversion kit are all separate. Many of these are available in our HVAC equipment add-ons section, and installation accessories can be bundled with the order.
