Air Handlers With Electric Heat Explained: Inside the Goodman MBVK Electric Furnace

When homeowners search for terms like air handler with electric heat or electric air handler, they’re often trying to understand how modern HVAC systems deliver heat without gas, oil, or combustion. These systems are common in all-electric homes, heat pump applications, manufactured housing, and regions where natural gas isn’t available.

At the center of this conversation is the electric furnace and air handler combination—and few products illustrate this better than the Goodman MBVK electric furnace. In this article, I’ll explain what an electric air handler is, how air handlers with electric heat work, how they differ from gas furnaces, and why the MBVK is designed the way it is. I’ll also cover installation considerations, performance expectations, troubleshooting basics, and who these systems are best suited for.

What Is an Electric Air Handler?

An electric air handler is the indoor component of an HVAC system responsible for moving conditioned air throughout the home. Unlike gas furnaces, an air handler does not burn fuel. Instead, it uses:

• A blower motor to circulate air

• Electric heating elements (often called heat strips) to generate heat

• A control board or sequencer to manage operation

• Safety switches to prevent overheating

When people refer to an air handler with electric heat, they are typically describing an air handler that includes integrated electric heating elements, allowing it to function as the primary heating source for the home.

This setup is common in:

• All-electric homes

• Heat pump systems (where electric heat provides backup or auxiliary heat)

• Manufactured and modular homes

• Mild to moderate climates

For a general overview of how air handlers function within HVAC systems, Energy.gov provides clear explanations of electric heating and air distribution principles.

How an Air Handler With Electric Heat Works

An air handler with electric heat operates on a straightforward principle: electric resistance heating combined with forced-air circulation. Here’s the process step by step:

1. Thermostat calls for heat
   The thermostat sends a signal indicating the indoor temperature has dropped below the set point.

2. Heating elements energize
   Electric heat strips inside the air handler begin heating. In systems like the Goodman MBVK, these elements are staged to avoid electrical overload.

3. Blower motor activates
   The blower pulls air from the return ducts, passes it over the heated elements, and pushes warm air through the supply ducts.

4. Safety controls monitor temperature
   High-limit switches ensure the system shuts down safely if temperatures exceed design limits.

5. Thermostat satisfies demand
   Once the set temperature is reached, the heating elements shut off and the blower ramps down.

Because electricity is converted directly into heat, electric air handlers are nearly 100% efficient at the point of use.

The Goodman MBVK: More Than a Basic Electric Air Handler

The Goodman MBVK electric furnace is often described as an electric air handler, but that label doesn’t fully capture its design. The MBVK is a dedicated electric furnace that integrates air handler functionality with advanced heating control.

Key design features include:

• Modular electric heating elements for staged heating

• ECM variable-speed blower motor for efficient airflow

• Advanced control board for sequencing and safety monitoring

• Multiple installation configurations (upflow, downflow, horizontal)

Unlike basic air handlers that rely on add-on heat kits, the MBVK is engineered from the ground up to provide reliable, whole-home electric heat.

For product specifications and configuration details, resources like Goodman offer technical references and installation documentation.

Electric Air Handler vs Gas Furnace

Understanding the difference between an electric air handler and a gas furnace helps homeowners choose the right system:

Because the MBVK does not use combustion, it eliminates components such as burners, igniters, flame sensors, and flue pipes. This results in fewer failure points and simpler maintenance.

For homeowners interested in comparing system types, DC Air provides consumer-friendly comparisons of electric and gas heating systems.

Air Handlers With Electric Heat in Heat Pump Systems

One of the most common applications for an electric air handler is in combination with a heat pump. In these systems:

• The heat pump provides primary heating under normal conditions

• Electric heat strips act as auxiliary or emergency heat

• The air handler distributes both heating and cooling air

The Goodman MBVK pairs well with heat pumps because:

• Its staged heat strips prevent sudden electrical demand spikes

• The ECM blower adapts airflow based on heating stage

• Controls integrate smoothly with modern thermostats

This makes the MBVK ideal for climates where heat pumps are efficient most of the year but need backup heat during colder periods.

Why Staged Electric Heat Matters

One of the most misunderstood aspects of electric air handlers is heat staging. Without staging, all heating elements would energize at once, which can:

• Trip circuit breakers

• Stress electrical components

• Create uncomfortable temperature swings

The MBVK uses staged heating, meaning:

• Heating elements energize in sequence

• Electrical load is spread over time

• Indoor temperatures rise more evenly

This approach improves comfort while protecting both the furnace and the home’s electrical system.

Installation Considerations for Electric Air Handlers

Installing an air handler with electric heat requires careful planning:

1. Electrical capacity
   Electric furnaces require adequate breaker sizing and wiring to support heating elements.

2. Ductwork compatibility
   Proper airflow is critical to prevent overheating and limit trips.

3. Clearances and orientation
   The MBVK supports multiple configurations, making it suitable for closets, attics, basements, and crawlspaces.

4. Thermostat selection
   Multi-stage thermostats maximize comfort and efficiency.

Professional installation is strongly recommended to ensure safety and performance. Manufacturer resources and distributors like The Furnace Outlet provide model-specific installation requirements.

Common Issues With Electric Air Handlers

Even well-designed systems can experience issues. Common problems include:

• Blower runs but no heat – Often caused by a failed heating element or control issue

• Breaker trips – May indicate electrical overload or shorted heat strip

• Insufficient heat – Could be undersized equipment or restricted airflow

• Frequent high-limit trips – Usually tied to dirty filters or blocked ducts

The MBVK’s integrated diagnostics and staged heating reduce the likelihood of these problems, but regular maintenance remains essential.

For troubleshooting guidance, American Home Water & Air provides step-by-step explanations for common electric furnace issues.

Maintenance Requirements for the Goodman MBVK

One advantage of an electric air handler or furnace is low maintenance. Recommended practices include:

• Changing air filters regularly

• Keeping supply and return vents unobstructed

• Inspecting electrical connections during annual service

• Ensuring blower motor operation remains smooth and quiet

Because there is no combustion, there is no need for flue inspections, gas pressure checks, or flame sensor cleaning.

Who Should Choose an Air Handler With Electric Heat?

An air handler with electric heat—especially a purpose-built unit like the Goodman MBVK—is ideal for:

• Homes without natural gas service

• All-electric new construction

• Manufactured and modular homes

• Heat pump systems needing auxiliary heat

• Homeowners prioritizing safety and low maintenance

While electric heating costs depend on local electricity rates, many homeowners value the simplicity, reliability, and safety profile of electric systems.
