2 Ton EcoTemp 16.5 SEER2 R-454B High-Efficiency Wall Mount Apartment/Condo AC System
Combining the EcoTemp W5A5S24AKAWA scroll condenser with the variable-tap ECM FMA5X2400AL fan coil, this 2 ton (24,000 BTU) R-454B system earns an AHRI-certified 16.5 SEER2 (AHRI #214878333), more than a full SEER2 point above the 2 ton PSC package. It is designed for one- and two-bedroom apartments and condos where the air handler hangs in a closet or mechanical niche, and where owners want premium efficiency, gentler airflow, and consistent performance even on 208 volt building power. Condo associations, owners renovating to sell, and contractors upgrading multifamily units get a high-efficiency apartment system without changing the closet footprint.
Is a 2 Ton High-Efficiency Wall Mount AC System the Right Size?
Most homes that call for 2 tons of cooling fall somewhere around 900 to 1,200 square feet, a range that fits many one-bedroom-plus-den and two-bedroom floor plans. That range is a rough guide; the cooling load of the specific unit, not the brochure square footage, is what sets the tonnage.
In multifamily buildings, the position of the unit plays a major role. An interior, middle-floor apartment shares walls, floors, and ceilings with conditioned neighbors and often needs less capacity, while a top-floor or end unit with more exterior wall and roof exposure can need more. Window orientation, climate zone, and how many people live in the space round out the calculation.
Ideal for: One-bedroom-plus-den and two-bedroom condos, renovated rental units marketed for low utility bills, condo associations standardizing on efficient equipment, and upgrades of 2 ton apartment-style closet systems.
Need more capacity? Step up to the 2.5 Ton EcoTemp 16 SEER2 W5A5S30AKAWA & FMA5X3000AL Wall Mount System for larger condos 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.

Frequently Asked Questions
Does the 2 ton FMA5X2400AL package suit a 1,000 sq ft apartment?
A 1,000 square foot apartment falls within the typical 900 to 1,200 square foot range for 2 tons, but unit position, windows, and climate matter. An interior unit may need less capacity, and a top-floor corner unit may need more, so a load calculation is the safest way to decide.
How does the FMA5X2400AL improve on the 1.5 ton FMA5X1800AL?
Both share the same 20-1/2" wide cabinet, 1/3 HP ECM motor, and 16.5 SEER2 system rating. The FMA5X2400AL ships on the highest airflow tap for 800 CFM nominal versus 650 CFM, and pairs with the larger W5A5S24AKAWA condenser for 24,000 BTU of nominal cooling instead of 18,000.
What warranty coverage comes with the W5A5S24AKAWA and FMA5X2400AL?
Both units carry a 5-year parts limited warranty that extends to a 10-year parts limited warranty when the equipment is registered within 90 days of installation. The W5A5S condenser also includes a 1-year unit replacement limited warranty. See the warranty documents for full terms.
Does the FMA5X2400AL lose airflow at 208 volts?
No. According to the FMA5 product data, the multi-tap ECM in the FMA5X is a constant-torque motor, so airflow at 208V is approximately the same as at 230V. That makes it a good fit for apartment and condo buildings supplied with 208V power.
What thermostat works with this 2 ton condo AC system?
The system works with standard or programmable 24V cooling thermostats. If an electric heat kit is installed, choose a thermostat with a heat stage as well, such as a conventional 1-heat/1-cool model.
What multifamily projects specify a 2 ton ECM wall-mount system?
Condo renovations, energy-focused apartment upgrades, and newer multifamily projects targeting lower utility costs often choose the ECM version. Learn why manufacturers moved to R-454B in our refrigerant transition explainer, or see the 2 ton EcoTemp FMA5X heat pump system for heat pump heating.
