2 Ton EcoTemp 15.5 SEER2 R454B Heat Pump Wall Mount Apartment/Condo Type System W5H5S24AKAAA, FMA5X2400AL
At 15.5 SEER2 (AHRI #214424066), this 24,000 BTU EcoTemp package ties with the 3 ton ECM system for the highest efficiency in the multifamily heat pump lineup. It matches the W5H5S24AKAAA R-454B heat pump with the FMA5X2400AL wall-hung fan coil and its constant-torque ECM blower. It suits condo owners who want lower utility bills and quieter, steadier airflow, and property managers trying to cut energy costs across a building of mid-size units.
Is a 2 Ton Heat Pump System the Right Size?
This system is built for loads around 24,000 BTU per hour, the sweet spot for many one-bedroom and modest two-bedroom units. Getting the size right is especially important with a high-efficiency system. Rated SEER2 savings only show up when the heat pump runs full, steady cycles, rather than short-cycling because it is oversized.
Look at more than floor area. Count exterior walls, note the direction of the main windows, check whether the unit sits under a roof, and consider how many people live there. Estimate your load with the BTU and tonnage calculator, and read the SEER2 efficiency guide to see how this rating compares.
Ideal for: One-bedroom and compact two-bedroom condos, owner-occupied units focused on energy savings, and efficiency upgrades from older 2 ton fan coil systems.

Recommended system sizes are general guidelines only. Actual requirements depend on climate, insulation, unit location within the building, window exposure, occupancy, and installation conditions. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

Frequently Asked Questions
What size condo is a 2 ton 15.5 SEER2 heat pump typically considered for?
It suits condos and apartments with a calculated load near 24,000 BTU, often one-bedroom and smaller two-bedroom layouts. The load depends on exposure, insulation and occupancy, so confirm with a sizing calculation before ordering.
How is the 2 ton FMA5X2400AL system different from the 1.5 ton FMA5X version?
Both use the same 20-1/2" cabinet and 1/3 HP ECM motor. The 2 ton FMA5X2400AL ships on Tap 5 for 800 CFM nominal, while the 1.5 ton FMA5X1800AL system ships on Tap 3 for 650 CFM. The 2 ton pairing is also rated higher, at 15.5 SEER2 versus 15.2.
Is there a cooling-only version of this 2 ton wall-mount system?
Yes. If the building uses another heat source, the 2 Ton EcoTemp W5A5S24AKAWA, FMA5X2400AL air conditioning system uses the same ECM fan coil with an AC-only condenser. This heat pump version provides both heating and cooling.
What is the factory blower setting on the FMA5X2400AL?
The 2 ton FMA5X2400AL ships on Tap 5 of its 5-speed ECM motor. The manufacturer's blower tables list airflow at each tap across a range of external static pressures, so installers can fine-tune airflow if the duct system needs it.
What thermostat works with the W5H5S24AKAAA heat pump?
The system has a 24V control circuit and supports both programmable and standard thermostats. Choose a heat pump-compatible model that can control the reversing valve and any auxiliary heat. Several options are available on this page.
Where do the condensate drains connect on the FMA5X2400AL?
Primary and secondary 3/4" FPT drain connections exit from the bottom of the cabinet, with an access panel in the bottom. This layout makes it easy to tie into an existing closet drain or a secondary safety line.
