2 Ton EcoTemp 16 SEER2 45K BTU Single Stage Gas System W5A5S24AKAWA, W5AM24M14XA, WFER045A036C
This is the balanced entry point in the EcoTemp gas system range and the configuration that fits the widest slice of small-to-midsize southern and coastal homes. The W5A5S24AKAWA condenser supplies 24,000 BTU/h of R-454B cooling at 16 SEER2, matched to a tonnage-appropriate W5AM24M14XA cased coil and a two-burner WFER045A036C furnace rated 44,000 BTU/h input and 36,000 BTU/h output at 80% AFUE. Every indoor component stays on the narrow A-size platform: a 14-3/16 inch furnace cabinet and a 14-inch coil cabinet, which is what lets a 2 ton system go into a closet, laundry alcove, or garage corner that will not accept a wider furnace. Typical fits are 1,000 to 1,400 square foot homes in Florida, Texas, the Gulf Coast, and the Southwest, where cooling runs most of the year and gas heat is a shoulder-season need.
Is a 2 Ton / 45K BTU Gas System the Right Size?
At 2 tons of cooling against 36,000 BTU/h of heat output, this is a cooling-forward package. The ratio suits climates where the design cooling load drives equipment selection and the furnace exists to handle a handful of cold weeks rather than a five-month heating season. In practical terms that means well-insulated homes roughly in the 1,000 to 1,400 square foot range, or somewhat larger in warm climates with good shading and modern windows. It is not the right pick for a northern installation, where the same 2 tons of cooling would typically be paired to a 66,000 or 88,000 BTU/h furnace instead.
Cooling load moves with glazing area and orientation, attic insulation and radiant barrier, roof color, duct location, infiltration, internal gains from occupants and appliances, and outdoor design temperature. Latent load matters as much as sensible load in humid regions, and a correctly sized 2 ton system will run longer cycles that pull more moisture out than an oversized 2.5 or 3 ton unit would. On the heating side, verify that 36,000 BTU/h of output covers your design heating load before assuming the smaller furnace is adequate.
Ideal for: Sun Belt single-family homes of about 1,000 to 1,400 square feet, coastal bungalows, duplex halves, mobile-to-site-built conversions with existing gas service, rental properties needing a straightforward single stage replacement, and closet installations restricted to a 14-3/16 inch cabinet width.
Need more capacity? Step up to the 2.5 Ton EcoTemp 15.2 SEER2 45K BTU Gas System W5A5S30AKAWA, W5AM30M14XA, WFER045A036C for more cooling on the same 14-3/16 inch furnace, or keep 2 tons and add heat with the 2 Ton EcoTemp 70K BTU Gas System WFER070A036C.
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.

Unlike the 1.5 ton systems in this range, which use an intentionally oversized coil to reach their efficiency rating, this package runs a coil sized directly to its 2 ton condenser. That keeps the indoor cabinet compact while the factory-installed R-454B TXV maintains correct superheat across the operating range. Line sets are not supplied; the W5A5S24AKAWA needs 3/4 inch vapor and 3/8 inch liquid tubing, available in our copper line sets and fittings section. For propane installations, add the EcoTemp AGAGC8NPS01C LP conversion kit from the drop-down option on this page; it is not included in the system price.

Frequently Asked Questions
How much square footage does 2 tons of cooling with 36,000 BTU of heat output cover?
In warm southern climates this configuration commonly serves roughly 1,000 to 1,400 square feet of well-insulated space, with the cooling side driving the selection. The 36,000 BTU/h heat output covers a proportionate load in mild winter regions. Both figures shift substantially with insulation, window area, and infiltration, so treat them as a starting point for a load calculation rather than a rule.
Why does this system use the W5AM24M14XA coil rather than the larger W5AM30M14XA?
The W5AM24M14XA is the tonnage-matched coil for a 2 ton condenser, with an airflow range of 600 to 1,000 CFM. The 1.5 ton systems in this range use the larger W5AM30M14XA specifically to gain efficiency from extra coil face area. Here the 24,000 BTU condenser already reaches 16 SEER2 with its own size class, so the matched coil keeps cost and cabinet volume down while remaining AHRI certified under number 214913631.
What electrical service and breaker size does the W5A5S24AKAWA need?
The condenser runs on 208-230V single phase 60 Hz with a minimum circuit ampacity of 13.6 amps and a maximum fuse or breaker rating of 20 amps. The furnace runs on a separate 115V circuit, and the control circuit is 24V supplied by the furnace transformer. Always confirm against the W5A5S installation instructions and local electrical code before wiring.
Can R-454B equipment reuse an existing R-410A line set?
Existing tubing can sometimes be reused if it is the correct diameter, in sound condition, and thoroughly cleaned or flushed of the previous oil, but R-454B is a mildly flammable A2L refrigerant with its own installation requirements. Line set reuse decisions, leak testing, and any required mitigation must follow the W5A5S installation instructions and applicable code. When in doubt, new tubing is the safer path.
Does the 14-3/16 inch cabinet limit a future upgrade to a larger air conditioner?
Less than you might expect. The WFER045A036C blower is rated to carry cooling airflow for systems up to 3 tons, so the furnace itself would not need replacing to support a larger outdoor unit. The coil would, since the W5AM24M14XA is sized for 2 tons. Duct capacity is usually the real constraint on any upsize, not the furnace cabinet.
How loud is the W5A5S24AKAWA outdoor unit?
It carries a 73 dBA rating, which is typical for a single stage residential condenser in this class. Placement matters more than the rating itself: keeping the unit away from bedroom windows and patios, on a level pad with the specified clearances, does more for perceived noise than a one or two decibel difference between models.
