Learn About HVAC Equipment: How Does an Air Handler Work?

What Is an Air Handler?

Air handlers have a starring role in the heating, ventilation, and air conditioning (HVAC) industry. If you have a ductless mini split system, independent air conditioner, or heat pump, an air handling unit (AHU) is necessary. It circulates heated or cooled air throughout your home, keeping your living space at the desired temperature.

If you want to know more about air handlers and how they work, continue reading for a detailed overview. We also invite you to contact us to schedule an appointment for an estimate if you’re in the market for a new AHU!

How Does an Air Handler Work?

HVAC air handlers help regulate indoor temperatures and control air circulation. Comprising four key components, together they perform essential functions to ensure optimal climate control.

1. The evaporator coil extracts heat and moisture from the air for cooling and warms the air for heating.
2. The blower motor circulates the air using a powerful fan.
3. Sound attenuators ensure quiet operation.
4. Air filters within the AHU enhance indoor air quality (IAQ) and safeguard the equipment from dust accumulation.

Types of Air Handlers

There are three main types of AHUs, including the single-speed model, which features a fan motor that operates at a single, unchanging speed. Then, five-speed air handlers that offer more effective air circulation and quieter operation. Finally, there are variable-speed handlers that adjust fan speed based on the user’s comfort needs. These units use minimal power to maintain your preferred indoor temperature.

What Size Air Handlers Are Available?

Air handlers are available for different spaces based on square footage. An appropriately-sized handler can efficiently distribute air throughout a space without consuming excess energy.

Smaller AHUs are for residential settings and there are different options available. For example, fan coil units are highly energy-efficient and commonly used in residences equipped with pre-existing ductwork.

Residential units are always going to be smaller and less intricate than their commercial counterparts.

A Makeup Air Unit (MAU) is a sizable AHU. They are primarily for commercial and industrial HVAC systems. These units use 100% outdoor air instead of circulating stagnant air that may contain odors and bacteria.

When Is an Air Handler Necessary?

You’ll need an air handler if your home depends on a ductless mini split system, heat pump, or independent AC unit. You do not need an air handler if you have a furnace or radiant heat.
