An air handler heater is a crucial component in many homes and buildings, responsible for providing warmth and comfort to its occupants. It's essentially a heating system that works in conjunction with an air handler to distribute warm air throughout a space.
The air handler heater is designed to be energy-efficient, using a heat exchanger to transfer heat from one medium to another, typically from hot water or steam to the air. This process allows for a significant reduction in energy consumption compared to traditional heating systems.
In many cases, an air handler heater is a cost-effective solution for heating a home or building, especially in areas with mild winters. By using a heat exchanger, it's possible to achieve a high level of efficiency while keeping costs low.

What is an Air Handler Heater?
An air handler heater is essentially a device that circulates and regulates air in your HVAC system.
It's usually placed in a bigger metal box containing various components such as filter chambers, dampers, and sound attenuators.
The air handler heater is designed to work with the duct ventilation system to distribute conditioned air through your home or building.
In some cases, an air handler heater can be designed to discharge and admit air to and from the space without duct work.
A small air handler heater, mostly for domestic use, includes a coil, air filter, and a blower.
Large air handler heaters designed to condition 100 percent outside air are called makeup air units, rooftop units, or packaged units, and are usually placed on roofs.

Types and Features
Air handlers come in compact, lightweight designs that are up to 12” shorter than comparable OEM models. This makes them a great choice for smaller spaces or tight installations.
You can choose from a variety of configurations, including upflow, downflow, and horizontal left or right. This flexibility allows you to customize the air handler to fit your specific needs.
Here are some key features to consider:
- Multi-position configurations
- Electric or no heat options
- PSC or 5-speed high-efficiency ECM motor
- Easy-to-access control panel
- Available in 208/240 V and 120 V
- Aluminum or copper coils
Variable-speed air handlers are a great option for multi-level homes, as they can run at slower speeds to provide optimal comfort and even air circulation. This can lead to lower energy costs and a more comfortable living space.

Types of Handlers

Single-speed air handlers are the cheapest option, but they only have two modes: 100% on or 100% off.
A two-speed air handler has a setting lower than 100% and can help circulate the air in your house more evenly.
Variable-speed air handlers have multiple blower settings, from 100% capacity to as low as around 40%.
They modulate between speeds to provide optimal comfort and can do an even better job of conditioning all the air in your home.
Running at a slower speed can lower energy costs and increase comfort, and the unit will have less starting and stopping.
A variable-speed air handler can keep a steady temperature in your home, even in multi-level homes, allowing the heat to spread throughout the home.
This results in a home without hot and cold spots, or wild spikes in hot or cold.

Electric Heat Strips
Electric heat strips are a crucial component of air handlers, especially for heat pumps. They serve as an auxiliary heat source during cold spells when the heat pump's ability to transfer heat effectively is compromised.

Heat pumps lose their ability to transfer heat when the temperature drops below freezing. This is a critical temperature threshold for heat pumps.
Electric heat strips are designed to kick in and provide supplemental heat during these cold periods. They're a necessary backup system to ensure your home remains warm and comfortable.
The primary function of electric heat strips is to provide heat when the heat pump can't keep up. This is usually during the coldest winter months when the temperature is at its lowest.
Components and Parts
An air handler heater consists of several key components that work together to deliver enhanced indoor comfort. The evaporator coil is one of these components, and it plays a crucial role in the heating and cooling process.
The evaporator coil extracts heat and moisture from the air for cooling and warms the air for heating. This is essential for maintaining optimal indoor temperatures.
A powerful fan is also necessary for circulating the air, which is provided by the blower motor. This ensures that the air is distributed evenly throughout the space.
Sound attenuators are also an important part of an air handler heater, as they help to ensure quiet operation. This is especially important in residential settings where noise can be a concern.
Air filters within the AHU (air handler unit) enhance indoor air quality (IAQ) and safeguard the equipment from dust accumulation. This is crucial for maintaining the longevity of the equipment and ensuring that the air is clean and healthy to breathe.
Here are the key components of an air handler heater:
- Evaporator coil: extracts heat and moisture from the air for cooling and warms the air for heating
- Blower motor: circulates the air using a powerful fan
- Sound attenuators: ensure quiet operation
- Air filters: enhance indoor air quality (IAQ) and safeguard the equipment from dust accumulation
Specifications and Costs
Air handlers come in a range of sizes, from 1.5 to 5 tons.
The motor options are also varied, with both 3 Speed PSC and 5-speed high-efficiency ECM motor available.
You can choose from units with no heat, or opt for electric heat that can be factory or field installed.
The cost of an air handler can range from $2900 to $5800, including installation.
Additional expenses include heat strips, which can cost between $300 and $600 to install.
Here are the key specifications at a glance:
- Size: 1.5 – 5 tons

Checking HVAC System Handler
If you have a heat pump, you'll need to check if your HVAC system has an air handler, which is the principal indoor component of your heat pump.
An air handler looks a lot like a furnace and contains a blower motor, evaporator coil, air filter, electrical components, and more.
You only need to worry about installing or servicing an air handler if you have a heat pump.
A mismatched system will perform 30% less efficiently than matching components, so it's crucial to replace both halves of the system at the same time.
You can check if you have a conventional furnace/AC combo by looking for a blower – if you only have a blower, you don't need to worry about an air handler.
The air handler must match your heat pump's capacity and seasonal energy efficiency ratio (SEER) for efficient performance.

Understanding and Choosing
Air handler heaters come in a range of sizes, from 20 to 100 tons, with 40-ton units being a popular choice for many homes.
The type of fuel used by the air handler heater is a crucial consideration, with natural gas being a common choice due to its relatively low cost and widespread availability.
A well-insulated home can reduce the heating needs of an air handler heater, but even with insulation, a 40-ton unit can still be effective in heating a 2,500 square foot home.

When to Use a Heater
You'll need a heater if your home relies on a heat pump or independent AC unit, as these systems often require supplemental heat to function properly.
A furnace is a type of heater, but you might not need one if you have a radiant heat system, which can be an efficient and effective alternative.
Why Do You Need a Handler?
You need a handler because it provides the force behind your HVAC system, allowing it to do its job effectively. Without a blower, the inside air would stagnate.
An air conditioner can expel as much hot air as it can, but it needs a handler to push that air out.
You'd usually pair a handler with a heat pump or an air conditioner, making it a crucial component of your heating and cooling system.
