Description
The Grandaire FMA5L2400AL is a 2‑ton (24,000 BTU) indoor air handler in the FMA5L Series, designed for vertical (upflow) orientation and flush mounting. It uses low‑GWP refrigerant R‑454B and incorporates factory-installed refrigerant leak dissipation systems. Powered by a multi-speed ECM blower, it integrates seamlessly with compatible condensing units for balanced, reliable airflow delivery. With galvanized steel housing, it’s built to provide efficient comfort in residential and light-commercial spaces.
Performance
Featuring a multi-speed ECM blower, this unit delivers airflow between approximately 600–900 CFM to suit various load conditions, enhancing both comfort and energy efficiency. The all-aluminum coil design resists corrosion and maximizes heat transfer, while the TXV metering device ensures accurate refrigerant flow. Although single-stage in operation, the ECM blower’s variable speeds adapt to changing system demands, improving overall HVAC performance.
Smart Features
The FMA5L2400AL is thermostat-agnostic and compatible with modern multi-stage or communicating smart thermostats. Its ECM motor supports zoning and variable airflow control, enabling energy-conscious setups in multi-family or light-commercial environments. When paired with a smart thermostat, it supports remote temperature management and enhanced energy savings.
Comfort & Noise
Its insulated cabinet and vibration-reducing design keep operational sound levels minimal, making it suitable for bedrooms and offices. The corrosion-free sloped drain pan and polymer cabinet liner help maintain indoor air quality, preventing mold and noise issues. Overall design ensures smooth operation with balanced temperature distribution.
Use Case Fit
Tailored for residential homes, apartments, condos, and light-commercial buildings, the FMA5L2400AL is ideal in regions with moderate HVAC demands. Its compact size and top-tier environmental compliance make it a fit for retrofit or new-build projects seeking future-ready HVAC solutions. The versatile blower and control options ensure reliable performance across varying climate zones.
Value & Reliability
Constructed with durable galvanized steel, insulated interiors, and corrosion-resistant coil, this air handler emphasizes long-term reliability. Factory-included refrigerant leak mitigation aligns with UL safety standards. With a reputation for low maintenance and extended service life, this model offers excellent return on investment for property managers and HVAC professionals.
