2 Ton EcoTemp 15.2 SEER2 R-454B Wall Mount Apartment/Condo Air Conditioning System
Pairing the EcoTemp W5A5S24AKAWA single-stage condenser with the FMA5L2400AL multifamily fan coil, this 2 ton (24,000 BTU) split system delivers AHRI-certified 15.2 SEER2 cooling (AHRI #214878255) on next-generation R-454B refrigerant. It is the workhorse size for one- and two-bedroom apartments and condos, where the slim wall-hung air handler tucks into a hallway or mechanical closet and the scroll-compressor outdoor unit sits on a pad, balcony, or rooftop. Apartment owners, maintenance teams, and HVAC installers get a code-ready replacement for aging R-22 and R-410A closet systems without rebuilding the closet.
Is a 2 Ton Wall Mount AC System the Right Size?
Two tons of cooling commonly serves living spaces in the neighborhood of 900 to 1,200 square feet, which covers a large share of one- and two-bedroom multifamily floor plans. That rule of thumb only holds when the unit has average insulation, moderate glass area, and no unusual heat sources, so treat it as a first check rather than a final answer.
Corner units with walls of windows, vaulted or 9-ft ceilings, a top-floor roof deck above, a hot Gulf Coast climate, or a busy household cooking every night can all push a home past what a 2 ton system will comfortably carry. On the other hand, a well-sealed interior unit may be better served by 1.5 tons. A room-by-room load calculation protects both comfort and humidity control.
Ideal for: One- and two-bedroom apartments, mid-size condos, townhome-style rentals with closet air handlers, workforce and military housing, and change-outs of existing 2 ton apartment-style fan coils.
Need more capacity? Step up to the 2.5 Ton EcoTemp W5A5S30AKAWA & FMA5L3000AL Wall Mount System for larger condos and multi-bedroom units requiring additional cooling capacity.
Recommended applications are general guidelines only. Actual system requirements depend on insulation, windows, sun exposure, ceiling height, climate, occupancy, and ductwork. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

The W5A5S24AKAWA moves 3,600 CFM across its condenser coil with a 1/10 HP direct-drive fan and ships with 4.7 lb of R-454B. Inside, the FMA5L2400AL PSC apartment air handler is factory set to high speed for a nominal 800 CFM and uses the same compact 20-1/2" wide cabinet as the 1.5 ton model. Both units connect with 3/4" suction and 3/8" liquid lines, so a 25 ft 3/4" x 3/8" copper line set covers most short-run apartment installs. For winter heat, add an EHK208B 7.5 kW heat strip or another EHK-series kit listed in the FMA5 product data.

Frequently Asked Questions
How many square feet can the 2 ton W5A5S24AKAWA system typically cool?
As a general guideline, a 2 ton apartment system often serves roughly 900 to 1,200 square feet. Sun exposure, insulation, ceiling height, and climate can move that range in either direction, so a load calculation is recommended.
What changes when stepping up from the 1.5 ton FMA5L1800AL package to the FMA5L2400AL?
Cabinet size stays the same, but the FMA5L2400AL uses a larger 1/5 HP PSC motor and moves a nominal 800 CFM versus 650 CFM. Outdoors, the W5A5S24AKAWA adds a 4.7 lb charge, a larger condenser coil, and a 20 amp maximum breaker. That makes the 2 ton a direct swap when an apartment needs more cooling but the closet cannot grow.
Why does the W5A5S24AKAWA use R-454B instead of R-410A?
New residential split systems are transitioning to lower global warming potential refrigerants. R-454B is non-ozone depleting and has a much lower GWP than R-410A, which is why the W5A5S24AKAWA and FMA5L2400AL are designed specifically around it. R-454B and R-410A equipment should not be mixed in the same system.
What breaker size does the W5A5S24AKAWA condenser call for?
The W5A5S24AKAWA lists a minimum circuit ampacity of 13.6 amps and a maximum time-delay fuse or circuit breaker of 20 amps on a 208/230V single-phase supply. The FMA5L2400AL air handler is wired on its own circuit; always confirm final sizing with the unit rating plate and local code.
Can the FMA5L2400AL be set up for bottom return?
Yes. The FMA5L2400AL can be converted to bottom return, which helps when the existing closet uses a floor or platform return. It must still be installed vertically in an upflow orientation.
Who typically buys a 2 ton apartment-style AC package?
Multifamily property managers, condo owners, landlords turning over rental units, and HVAC contractors handling apartment change-outs buy this size most often. Browse more wall-hung options in our condo and apartment-style air handler selector.
