Fan Coil Units

Energy-efficient fan coils help improve the performance of your home comfort systems by elevating SEER2, EER2, and HSPF2 ratings. Choose variable-speed models to help lower heating and cooling bills associated with your HVAC system and reduce environmental impact.

Humidity plays a big role in overall comfort, and advanced technology like variable-speed and two-speed fan coils helps regulate it more effectively. These systems ensure consistent and comfortable home temperatures, no matter the weather, by managing humidity levels and airflow.

Fan coils with variable-speed or two-speed blowers improve air circulation, reducing hot and cold spots for a more even indoor environment. Pair them with indoor air quality (IAQ) add-ons to not only enhance comfort but can also improve the air quality throughout your home.

Carrier fan coils are designed to optimize performance as part of a comprehensive home comfort system. Whether paired with an air conditioner or a heat pump, these units are engineered to deliver peak efficiency and operation.

Achieving optimal performance hinges on creating a matched system. For instance, pairing an Infinity® series fan coil with an Infinity series heat pump and an Infinity® system control unlocks the highest levels of comfort and energy efficiency. Similarly, Performance™ and Comfort™ series components are designed to work together seamlessly.

Your choice in staging—from single-stage to two-stage or fully variable-speed models—directly impacts efficiency and comfort. Variable-speed fan coils, for example, can make gradual adjustments to airflow, providing more consistent temperatures and quieter operation. The right control or thermostat integrates these components, giving you precise command over your entire system.

In residential HVAC, the terms fan coil unit and air handling unit are often used interchangeably. Both refer to the indoor component that houses the fan, coil, and other elements responsible for circulating conditioned air throughout your home.

A fan coil unit is the essential indoor component of your home's cooling or heat pump system, responsible for circulating conditioned air to keep you comfortable year-round. While sometimes called an air handling unit (or AHU), in residential systems, the correct term is fan coil unit. Think of it as the powerful heart of your HVAC system, working quietly behind the scenes.

Inside a fan coil unit, you'll find a few key parts working together:

• The Blower: A powerful fan that draws air from your home into the unit.

• The Coil: Depending on the mode, this coil either removes heat and humidity to cool the air or adds heat to warm it, as part of a heat pump system.

• The Control Board: This is the brain of the operation, ensuring all components work together to deliver precise comfort.

The process is simple but effective: the blower pulls air from your rooms across the coil. In cooling mode, the coil removes heat and humidity, sending cooled air back through the ductwork. In heating mode, when paired with a heat pump, the coil warms the air before distributing it throughout your home. For homes in especially cold climates, optional electric heat strips can be added to provide supplemental heating when needed.

Because they are designed to be out of sight, these units are typically installed in a utility closet, basement, or attic, integrating seamlessly into your home.

In residential settings, the terms fan coil (FCU) and air handler are often used interchangeably, as both refer to the indoor unit that houses the blower and coil to circulate conditioned air. While specific terminology can sometimes vary based on the overall system design, the core function remains the same: moving air to keep your home comfortable.

What matters most is ensuring your system components are designed to work together. Carrier fan coil units are engineered for seamless pairing with compatible Carrier outdoor units and controls. To unlock optimal performance, maximize efficiency, and protect your warranty, always consult a trusted dealer to confirm proper model matchups for your complete home comfort system.Carrier also offers ductless mini splits which are flexible cooling solutions that doesn’t require ductwork. Mini splits are also an energy efficient option and don’t obstruct a window, unlike a bulky window air conditioner.

Air conditioners are available in a variety of capacities, typically ranging from 1.5 tons to 5 tons. The size and layout of your home play a crucial role in determining the appropriate unit size. Whether your home is 2,000 square feet or exceeds 5,000 square feet, there is a suitable air conditioning solution for most every situation. To ensure you select the right size air conditioner for your home, we recommend scheduling a consultation with a local Carrier expert.

Regardless of your situation, you can have confidence that Carrier has an AC system that can meet your home comfort needs.

Yes, upgrading to a modern fan coil unit is a significant step toward greater home comfort and efficiency. Newer units, especially those with variable-speed ECM blowers, can substantially boost your system's overall energy efficiency. By running for longer periods at lower speeds, they minimize the inefficient on-and-off cycling of older, single-speed models, leading to more consistent temperatures and reduced energy consumption.

This steady, gentle airflow also creates a healthier home environment. Constant air circulation allows your system's filter to work more effectively, capturing more dust, pollen, and other airborne particles to improve indoor air quality. This process also provides better humidity control for a more comfortable feel in every room.

Ultimate savings and performance gains depend on a complete system approach. The true benefit is unlocked when your new fan coil is correctly sized, professionally installed, and part of a matched system with a compatible outdoor unit, well-maintained ductwork, and a smart thermostat.

Yes, absolutely. Carrier fan coil units are engineered to create a complete, high-performing home comfort system when paired with either our compatible heat pumps or air conditioners. The key to unlocking improved comfort and efficiency is ensuring the components are a perfect match.

For a system to deliver on its promise, the refrigerant type, system capacity, and controls must be correctly aligned. We recommend selecting an AHRI-rated combination, which certifies that the system will perform as specified. These matched systems are often a requirement for utility rebates and ensure you get the full benefit of Carrier innovation.

To guarantee compatibility, especially if you are considering upgrading just your indoor unit to work with an existing outdoor unit, it is essential to consult a trusted Carrier dealer. They can verify the proper matchups to optimize performance and protect your investment.

Think of electric heat strips as the ultimate backup plan for your home comfort. While modern heat pumps are engineering marvels designed for efficiency, extreme weather sometimes demands a little extra power. Electric heat strips provide that critical supplemental warmth, kicking in during the coldest days or when you need to raise your home's temperature quickly.

Is this upgrade right for you? It comes down to your specific needs. If you live in a colder climate or prioritize rapid warming, these strips can bridge the gap between a chilly morning and immediate comfort. Factors like your local energy costs and thermostat settings also play a big role in finding the right balance between efficiency and performance.

Carrier fan coils are built for this kind of adaptability. Many of our units support optional electric heat kits that professional installers can precisely size and fit to your system. To make the best choice, connect with your local Carrier dealer. They can evaluate your home and help you decide if adding electric heat is the smart move for your year-round comfort.

Protecting your investment and ensuring peak performance starts with proactive care. The most critical task you can handle yourself is maintaining the air filter. Whether disposable or washable, inspect it monthly and replace or clean it according to the schedule in your Carrier owner's manual. A fresh filter creates a barrier against dust and debris, keeping your system running smoothly.

For everything else, turn to the experts. We recommend scheduling a professional service visit at least once a year. During this tune-up, a technician will clean the indoor coil, clear the condensate drain, and inspect the blower motor and electrical connections. These precision adjustments are vital for maintaining energy efficiency and healthy indoor air. Sticking to this routine not only helps extend the life of your unit but also ensures you remain compliant with warranty terms.
