Carrier Air Handler Price, Review and Buying Guide

Carrier air handlers are also called fan coils – Carrier’s preferred term. While a Carrier fan coil will work with any brand equipment, they are typically installed with Carrier complete split HVAC systems – Carrier heat pumps or central air conditioners. They include the blower motor and fan plus the indoor coil through which refrigerant from the outdoor unit circulates. In HVAC literature, fan coils are often abbreviated FCUs (fan coil units) and AHUs (air handler units).

If you’d like to learn more about air handlers/fan coils before getting into the specifics of Carrier air handlers, our Air Handler Buying Guide provides comprehensive research.

Introduction to Carrier Air Handlers

Carrier makes six split-system fan coils in the brand’s typical basic/better/best series. Our list starts with the top model, the Infinity air handler. The table below lists the current models and their features.

1). System Options: All Carrier air handlers can be outfitted with electric resistance heat units of 5kW-20kW for backup/emergency heat or occasional heat in AC-only split systems.

2). Communicating systems: The Infinity FE4 and FE5 models must be installed in a system supported by a communicating control. The wiring is not the same as wiring for non-communicating controls. A communicating system is one that uses data communicated to the thermostat control from indoor and outdoor air temperature sensors and from the AC or heat pump. The purpose is to optimize heating and cooling efficiency and comfort based on precise climate-control data. Communicating systems also alert homeowners and technicians to the need for system maintenance and repair before minor issues progress to major repair problems. Carrier currently makes three Wi-Fi communicating controls:

  • Infinity system control SYSTXCCITC01-B
  • Infinity Remote Access touch control SYSTXCCITC01-A
  • Infinity Remote Access touch control with wireless router SYSTXCCITW01-A

The brand makes one communicating control that is not Wi-Fi:

  • Infinity Touch control SYSTXCCITN01-A

3). BTUH/Tons: Carrier lists its fan coil capacities by tons, 1.5 tons to 5.0 tons. Each ton is the equivalent of 12,000 BTUH, which is the amount of heat the unit can move per hour.

We’ve completed model overview tables and price tables (see below) for other top brands. For comparison, see our air handler guides to:

Carrier Air Handlers Features Analysis

Carrier Infinity and Performance Series fan coils can be outfitted with the brand’s Ideal Humidity System technology that monitors indoor humidity at the thermostat and will automatically run the system in fan-only mode between AC cycles. The result is improved dehumidification while air conditioning your home. Lower humidity makes air more comfortable at higher temperatures, so you can save money by setting your thermostat to 76 rather than 72, for example, and feel just as cool. Infinity fan coils matched with Infinity Touch Control models and a system humidifier will deliver ideal humidity levels when heating your home too.

Carrier ArmorTech coil protection is available on all Carrier fan coils. It is a coil coating that protects the coil against corrosion. Across the HVAC industry, companies have struggled to find ways to prevent corrosion caused by sea salt in the air but also by common household products such as wet paint, aerosol spray and cleaning products. ArmorTech coating is Carrier’s answer on all models. Carrier uses an additional coating called ArmorCoat on its tin-plated copper coils.

Infinity and Performance air handlers are equipped with washable air filters, which reduce maintenance costs if you prefer to wash them. They can also be replaced when dirty by non-Carrier branded air filters, though some consumers report that finding the right size replacement filters is difficult.
