Carrier FT5 Performance™ Fan Coil
Variable Speed Constant Airflow Motor - Puron Advance™ Refrigerant
Sizes 24-60
Product Data
The FT5 is a premium air handler that combines Carrier's proven fan coil technology with the environmentally balanced Puron Advance® refrigerant. It features Carrier's InteliSense™ technology, a connected system solution when paired with Internet-connected Ecobee smart thermostats, designed to deliver a smarter, faster, and more efficient service experience for homeowners. The FT5 offers an operational advantage through its variable speed ECM (Electronically Commutated Motor) when paired with a Carrier Performance™ heat pump or air conditioner utilizing Puron Advance® refrigerant.
Carrier has developed a new benchmark for superior indoor comfort and control, focusing on quiet, efficient, and comfortable operation.
Carrier's heat pump and air conditioning systems utilize Puron Advance® refrigerant (R-454B), a chlorine-free refrigerant positioned as the future for the residential heating and cooling industry. The FT5, using Puron Advance® refrigerant, maximizes performance for environmentally balanced systems. These systems offer 30% to 40% greater efficiency than standard heating and cooling systems, combining environmental responsibility with excellence in efficiency.
The FT5's benefits are driven by Carrier's expertise in ECM technology. These motors are highly efficient across all speeds, enabling the FT5 to operate at the precise speed required for optimal airflow delivery, ensuring proper performance across a wide range of duct static pressures. This adaptive efficiency also simplifies installation quality for homeowners.
Carrier's ECM technology is particularly evident in the comfort advantages it provides. The InteliSense™ Board offers setup alternatives for technicians to maximize comfort and efficiency. For enhanced indoor comfort, homeowners can achieve precise control over both temperature and humidity in cooling and heating modes.
Further enhancing the FT5's performance is the factory-installed TXV (Thermostatic Expansion Valve), which improves efficiency and protects the compressor under all recommended conditions. Grooved tubing, louvered aluminum fins, and large face areas on the FT5 refrigerant coils contribute to superior efficiency and high SEER and HSPF performance. Carrier is recognized for its advanced condensate control, a hallmark of its multipoise fan coils. All components are housed within a rugged, pre-painted metal cabinet lined with high-density insulation. For ease of installation, the unit exterior features sweat refrigerant connections for leak-free performance and multiple electrical entry points for both high and low voltage service.
The units are assembled to comply with low leakage requirements, tested to ASHRAE 193 standard, achieving less than 2% cabinet leakage at 1 inch W.C. and 1.4% at 0.5 inches W.C.

Acceptable Duct Conditions
For optimal operation, particularly for maintaining a dry secondary trap, fan coils must be installed with duct systems falling within the 'Acceptable Range' depicted in performance charts. These charts illustrate nominal airflow delivery versus duct system static pressure drop for heating and cooling modes. Cooling mode is shown with solid vertical lines, and heating mode with dashed vertical lines. Dotted curves represent static pressure drop characteristics for fixed duct systems, aiding in predicting system static pressure at any airflow based on a known point.
For example, a duct system designed for a 0.15 in. W.C. drop at 1200 CFM would result in the FT5 (036 size) delivering 1050 CFM with a 0.11 in. W.C. drop in cooling mode (Point 1). In heating mode, it would deliver 945 CFM with a 0.09 in. W.C. drop (Point 2). The FT5 can deliver these airflows against significantly higher static pressures.
