Most heat pumps and AC systems come with an air handler, but not all do. For example, an electric heat pump may require purchasing one separately. To understand whether your heat pump needs an air handler, we’ll look at what this component is and how it works in more detail.
What Does an Air Handler Do?
An air handler is a crucial HVAC component. It has a cased design that incorporates a blower, air filter, ventilation components, and evaporator coils. The primary function of an air handler is to transfer cooled air into the ductwork so it’s distributed throughout your home. An air conditioner works by extracting heat to reduce air temperature, while an air handler is solely responsible for transferring cool air.
Can I Go Without an Air Handler?
You probably won’t need a separate air handler for a furnace. Most furnaces have a built-in blower that distributes hot air. Homes in colder climates usually have one, so they don’t require an air handler. But while heat pumps provide both heating and cooling, they do need equipment to move air around. If you live in a warmer climate and don’t use a furnace, a heat pump can be an efficient solution; it’s quite common in southern regions.
Benefits of an Air Handler
Pairing your heat pump with an air handler can result in the following benefits:
- Reduced wear and tear on the heat pump
- Increased HVAC system longevity
- Energy efficiency (when compatible with existing equipment)
- A higher level of comfort
- Different types and sizes are available
Types of Air Handlers
The type of air handler you need is a consideration when choosing one. Smaller types are called terminal units, fan coil units, or blower coils. A makeup air unit is a larger air handler that only conditions air from outside. No air is recirculated. Rooftop units are only designed for outdoor use and are generally installed on the roofs of commercial buildings.
Do I Need a New Air Handler for My Heat Pump?
The air handler can be replaced individually if it matches your heat pump. Air handlers are durable machines but start to wear down after a few years. Whether a heat pump needs an air handler as a replacement can be determined if you notice:
- Poor Airflow: If the airflow from vents is weak or fluctuates, the blower motor may fail. The unit can fail if this issue isn’t addressed. Cleaning, repairing, and replacing the motor can help your air handler last longer.
- High Energy Bills: Your energy bill may be higher in winter or summer, but an unusual spike can mean your air handler is malfunctioning. We suggest contacting your local HVAC company to check the air handler and other components for issues.
- Frozen Coils: If your heat pump freezes in summer, it may have a clogged air filter, dirty evaporator coils, or refrigerant leak. Routine maintenance allows a technician to find and address these issues to avoid bigger problems with your HVAC system.
Replacing an air handler by itself is possible. However, it must be compatible with all parts of your HVAC system. Contact your local HVAC company for help purchasing and installing an air handler suited for your heat pump.
