When people start shopping for heating systems, they often use terms like “furnace,” “air handler,” and “heat pump” interchangeably—sometimes with confusing results. The reality is that these terms describe very specific pieces of HVAC infrastructure that work together (or independently) to deliver comfort throughout your home. One of the most important distinctions you’ll encounter is between traditional combustion‑based furnaces, mechanical air handlers, and the rising class of air handlers with electric heat—including the Goodman MBVK electric system.
In this comprehensive guide, we’re going to:
-
Define what an air handler with electric heat really is
-
Explain how the Goodman MBVK functions as an electric air handler and furnace
-
Compare it to other heating concepts like gas furnaces and heat pumps
-
Drill into performance, efficiency, maintenance, and installation nuances
-
Provide clarity that lets you make confident technology decisions
The objective here isn’t just to inform you—it’s to align technical understanding with practical, real‑world outcomes for homeowners, installers, and service professionals alike.
1. What Is an Air Handler With Electric Heat?
At its core, an air handler is the indoor mechanical component of a forced‑air system. It contains a blower motor, a coil (for cooling), and duct connections to move air throughout your home. When you add electric heating elements to an air handler, the system becomes capable of providing heat in addition to—or instead of—cooling. In other words, the air handler doesn’t just move air. It conditions it by adding warmth when needed. A unit with this capability is often described as an air handler with electric heat.
This concept often raises questions like:
-
Is this an “electric furnace”?
-
How does it differ from a condenser/air handler paired with a compressor outside?
-
Why is this configuration relevant today?
The answers lie in the increasing adoption of modular systems that not only maximize flexibility but also simplify installation for homes without natural gas or propane fuel. In models like the Goodman MBVK, the air handler is the furnace when equipped with electric heat kits—no combustion, no venting, no fuel supply connections required.
That means when a thermostat calls for heat, this electric air handler uses internal resistance elements to generate warmth, then relies on the blower system to circulate that conditioned air throughout your home’s ductwork. Whether installed as a standalone heat source or in conjunction with a heat pump, this setup is one of the cleanest and most compact heating solutions on the market.
2. The Goodman MBVK: A Multi‑Position Electric Air Handler That Heats
Before digging deeper into how the MBVK operates in heating mode, let’s frame what it actually is: the Goodman MBVK is a modular blower platform that can be configured as a cooling‑only air handler, a hybrid heat pump interface, or a full air handler with electric heat when paired with the right electric heat kit.

This versatility is one of the unit’s greatest strengths. What starts as a flexible indoor blower can transform into a complete electric heating system simply by adding electric heat strips sized to your home’s heating load. The unit’s variable‑speed ECM blower helps optimize airflow and humidity control regardless of application, while integrated safety and control logic ensure that heat is delivered consistent with thermostat demand.
When configured with electric heat, the MBVK functions very much like what many people think of when they hear the word “furnace”—but with key distinctions. There’s no combustion involved. Instead, its heating elements rely on electrical resistance similar to a baseboard heater, only scaled up and integrated into a ducted air distribution system.
3. Electric Air Handler Versus Traditional Furnace: Key Differences
One of the foundational misunderstandings in HVAC is assuming that “furnace” only refers to gas‑burning units. Electric systems deserve their rightful place in that category, particularly when they deliver heat at scale through integrated ducting and thermostat control.
Here’s how an electric air handler like the Goodman MBVK differs from typical combustion furnaces:
3.1 Heat Generation
-
Electric Air Handler With Electric Heat: Uses electrical resistance elements to generate heat within the air handler cabinet. No fuel is burned.
-
Traditional Furnace: Typically uses natural gas or propane that burns fuel to produce heat transferred through a heat exchanger that warms air delivered by the blower.
This distinction has major implications for fuel sourcing, venting requirements, and operational safety.
3.2 Venting and Safety
Gas furnaces require combustion air intake, safe removal of exhaust gases, safety interlocks, and ongoing combustion safety checks as part of regular maintenance. Because an electric air handler doesn’t combust any fuel, it eliminates these requirements entirely and sidesteps those categories of potential failure or risk.
This is one reason many homeowners view electric systems as safer and easier to maintain—especially in living spaces where gas infrastructure isn’t readily available or is cost‑prohibitive to install.
3.3 Energy Delivery and Performance
Electric resistance heating is nearly 100% efficient at the point of use, since virtually all incoming electrical energy is converted into heat. That doesn’t inherently mean lower overall utility costs, but it does mean predictable performance and straightforward energy accounting.
Conversely, gas furnaces are measured in AFUE (Annual Fuel Utilization Efficiency), with high‑efficiency condensing units achieving 90–98% AFUE. While gas may be less costly per delivered BTU in some regions, the furnace must still burn fuel and manage exhaust gases.
3.4 Component Simplicity
Because an electric air handler eliminates burners, heat exchangers, fuel valves, combustion chambers, and flue systems, it also reduces the number of mechanical components that can fail over time. That simplicity is not trivial: fewer moving parts often translate to fewer service calls and simpler maintenance.
4. Inside the Goodman MBVK: How the Electric Air Handler With Electric Heat Works
To understand how this configuration functions as a home’s primary heating source, you need to grasp the interplay of components inside the MBVK.
4.1 The Blower System
The MBVK features a variable‑speed ECM blower motor, which drives conditioned air through the ductwork. The variable‑speed capability allows it to match airflow to system demands smoothly, improving comfort and reducing noise compared to traditional single‑speed blowers.
When a thermostat calls for heat:
-
The control board energizes the blower at an appropriate speed.
-
The blower pulls return air from the home’s duct system.
-
Air enters the MBVK cabinet where the heat elements will warm it if needed.
4.2 Electric Heat Elements
Electric heating in this system is provided by field‑installed electric heat strips that are sized based on your home’s calculated heating load. These resistance elements generate heat when electrical power flows through them; heat is then transferred to the moving airflow stream.
This heat production is fundamentally different from combustion and has implications for airflow management:
-
Too little airflow can cause overheating and safety shutdowns.
-
Proper staging of heat elements prevents electrical overload.
-
Integration with the blower control ensures heat is delivered consistently.
4.3 Sequencing and Staging
Most installations use sequenced heating that brings electrical heat elements online gradually to match thermostat demand while minimizing electrical draw and temperature spikes. This staged approach also extends the life of heat strips and reduces stress on the electrical system.
When all required signals coincide (thermostat call + safe airflow conditions + sequencer activation), the heat elements energize. Heated air then flows from the MBVK into your home’s duct system—a process that continues until the thermostat’s setpoint is reached.
5. Installation Flexibility and Practical Considerations
One of the most striking benefits of an electric air handler like the MBVK is installation flexibility. Unlike traditional furnaces, which are often constrained to specific orientations and locations because of venting and combustion air requirements, air handlers with electric heat can be installed:
-
Vertically
-
Horizontally
-
In attics, basements, or closets
This flexibility can be especially valuable in retrofit scenarios or homes with limited mechanical space.
That said, professional installation remains critical. HVAC codes and electrical codes must be respected during wiring, breaker sizing, heat kit installation, and ductwork integration. This ensures not only safety but also long‑term system performance.
6. Air Handler With Electric Heat in Hybrid Systems
One of the most compelling use cases for the Goodman MBVK is as part of a hybrid HVAC system. In these setups:
-
A heat pump handles heating during mild weather efficiently.
-
The electric heat strips inside the electric air handler engage as auxiliary or emergency heat when outdoor temperatures drop.
This allows you to take advantage of the cost‑efficiency of a heat pump for most of the season, while relying on the electric furnace when temperatures dip and the heat pump’s efficiency declines.
This hybrid strategy is not only effective—it’s also increasingly common in areas where electricity is relatively affordable and where residents want to avoid gas infrastructure altogether.
7. Maintenance and Longevity
A common question homeowners ask is: “How much maintenance will this setup need?”
With an air handler with electric heat like the MBVK:
-
There are no burners to clean.
-
No combustion chamber inspections.
-
No flue gas or exhaust-related checks.
-
No condensate drain lines to worry about (except in cooling mode).
Maintenance tends to focus on airflow, filters, electrical connections, and blower performance. Routine filter changes and periodic blower motor checks help the system deliver optimal comfort without the complexity that accompanies combustion systems.
This simplicity doesn’t mean no maintenance; it means fewer moving parts and reduced categories of routine service.
8. Comfort, Performance, and Cost Considerations
When comparing an electric air handler to other heating options, it’s important to look beyond simplistic “efficiency” percentages and consider the overall context:
-
Electric resistance heat is nearly 100% efficient at the point of use.
-
Electric systems often deliver steadier, more consistent heat without aggressive cycling.
-
Variable‑speed blowers improve comfort by minimizing drafts and temperature swings.
-
The lack of combustion risks removes one whole class of safety concerns from the homeowner’s checklist.
Costwise, utility rates and regional price structures will ultimately determine whether electric heating is more economical than gas or hybrid heat pump systems—but the MBVK’s predictable heat delivery and low mechanical complexity often make operating costs easier to forecast.
