As residential HVAC systems continue to evolve, homeowners are hearing the terms air handler with electric heat and electric air handler more frequently than ever. These systems are especially common in homes without access to natural gas, in all-electric residences, and in regions where heat pumps are widely used. One product that often enters this conversation is the Goodman MBVK electric furnace, a system that blurs the line between traditional electric furnaces and advanced electric air handlers.
In this article, I’ll explain what an electric air handler is, how an air handler with electric heat works, and where the Goodman MBVK fits into this category. We’ll also explore system design, performance expectations, common issues, and maintenance considerations so homeowners can make informed decisions about electric heating.
What Is an Electric Air Handler?
An electric air handler is the indoor component of an HVAC system responsible for moving air through ductwork and, when equipped with heating elements, providing electric heat. Unlike gas furnaces, electric air handlers do not burn fuel. Instead, they rely on:
-
A blower motor
-
Electric resistance heating elements (heat strips)
-
Control boards and safety switches
Electric air handlers are commonly paired with heat pumps, but they can also function as standalone heating systems in colder climates. When used without a heat pump, the electric heat strips become the primary heat source.
The Goodman MBVK is often categorized as an electric furnace, but functionally it operates very much like a high-capacity electric air handler with integrated electric heat.
For an overview of how electric air handlers fit into modern HVAC systems, the U.S. Department of Energy provides a helpful explanation of heating and air distribution fundamentals.
Air Handler With Electric Heat vs Traditional Electric Furnace
The distinction between an air handler with electric heat and a traditional electric furnace is subtle but important.
Traditional Electric Furnace
-
Designed primarily for heating
-
Uses electric resistance elements as the main heat source
-
Typically installed where no heat pump is present
Air Handler With Electric Heat
-
Designed to move air year-round
-
Often paired with a heat pump for primary heating and cooling
-
Uses electric heat strips as auxiliary or backup heat
The Goodman MBVK electric furnace sits comfortably between these two categories. It provides robust electric heat while also functioning as a powerful air handler, making it compatible with cooling-only systems or heat pump configurations.
This versatility is one reason the MBVK is popular in both new construction and retrofit applications.
How the Goodman MBVK Operates as an Electric Air Handler
At its core, the Goodman MBVK includes all the components you would expect in an electric air handler:
-
Multi-speed blower motor
-
Electric heating elements
-
Heat sequencers or electronic controls
-
High-limit safety switches
-
Integrated control board
When the thermostat calls for heat, the control board energizes the heat strips in stages. Once the elements reach operating temperature, the blower motor circulates warm air through the duct system.
If paired with a cooling system, the same blower distributes cooled air during summer months. This dual-purpose operation is the hallmark of an air handler design.

Why Electric Air Handlers Are Growing in Popularity
Several trends are driving increased adoption of electric air handlers and air handlers with electric heat:
1. Electrification of Homes
As more homes move away from fossil fuels, electric heating solutions are becoming the standard rather than the exception.
2. Compatibility With Heat Pumps
Electric air handlers integrate seamlessly with heat pumps, providing backup heat during cold weather when heat pump efficiency drops.
3. Safety
Electric systems eliminate combustion risks such as carbon monoxide leaks and gas line failures.
4. Installation Flexibility
Electric air handlers like the MBVK do not require flue venting, combustion air, or gas piping, making installation simpler in many homes.
The Goodman MBVK addresses all of these trends while offering the output capacity needed for whole-home heating.
Understanding Heat Strips in an Electric Air Handler
Electric heat strips are the heart of any air handler with electric heat. These components convert electrical energy directly into heat through resistance.
How Heat Strips Work
-
Electricity flows through a resistive element
-
The element heats rapidly
-
Air passes over the element and absorbs the heat
-
Warm air is distributed through the ducts
In the MBVK, heat strips are staged to reduce electrical demand and improve comfort. Instead of energizing all elements at once, the system brings them online gradually.
This staged approach helps prevent:
-
Voltage drops
-
Circuit breaker trips
-
Sudden blasts of extremely hot air
For safety and performance standards related to electric heating elements, the National Fire Protection Association provides detailed electrical and fire safety guidelines.
Blower Performance and Airflow Design
An effective electric air handler must move air efficiently and consistently. The Goodman MBVK uses a high-capacity blower designed to maintain proper airflow across heating elements.
Proper airflow is critical because:
-
Too little airflow causes overheating and safety shutdowns
-
Too much airflow reduces air temperature and comfort
-
Balanced airflow ensures even heating throughout the home
Duct design, filter condition, and blower speed all affect performance. This is why air handlers require careful sizing and professional installation.
Energy Star emphasizes the importance of proper airflow and duct sealing in achieving efficient heating and cooling performance.
Common Issues With Air Handlers Using Electric Heat
Even well-designed systems can experience issues. Many common complaints related to electric air handlers include:
Blower Runs but No Heat
Often caused by:
-
Tripped high-limit switch
-
Failed heat strip
-
Sequencer or control board issue
Short Cycling
Frequently related to:
-
Restricted airflow
-
Incorrect thermostat configuration
-
Oversized system
Uneven Heating
May indicate:
-
Improper duct design
-
Incorrect blower speed settings
-
Inactive heat strip stages
The MBVK includes multiple safety devices to protect against these problems, but routine maintenance is essential.
Maintenance Requirements for the Goodman MBVK
Maintaining an electric air handler is generally simpler than maintaining a combustion-based system, but it is still essential.
Key Maintenance Tasks
-
Replace air filters regularly
-
Inspect blower motor and wheel
-
Check electrical connections
-
Test heat strip operation
-
Verify safety switch function
Annual professional inspections help ensure reliable performance and extend system lifespan.
Energy Efficiency Considerations
Electric air handlers convert nearly 100% of electrical energy into heat at the point of use. However, overall efficiency depends on:
-
Electricity cost
-
Insulation quality
-
Duct efficiency
-
Thermostat programming
When paired with a heat pump, the MBVK can serve as auxiliary heat, allowing the heat pump to handle most heating needs while electric strips engage only when necessary.
This hybrid approach offers excellent comfort and efficiency in many climates.
Installation Flexibility of the Goodman MBVK
The MBVK can be installed in multiple configurations, including:
-
Upflow
-
Downflow
-
Horizontal
This flexibility makes it suitable for basements, closets, utility rooms, and manufactured homes. Its compact design allows it to function as a central electric air handler without occupying excessive space.
Who Should Consider an Air Handler With Electric Heat?
You may benefit from a system like the Goodman MBVK if:
-
Your home is all-electric
-
You are installing or upgrading a heat pump
-
You want to eliminate combustion appliances
-
You prefer lower maintenance heating systems
-
You need flexible installation options
Electric air handlers provide dependable comfort without the complexities of gas heating.
