Few components in your HVAC system are as critical—and as misunderstood—as the heating element. Whether you’re talking about a central air heating element, a furnace heating coil, or an electric furnace heating element, understanding how these parts function is key to keeping your home warm efficiently and safely. If you’ve ever searched for topics like electric furnace heating element replacement or wondered about the cost of a furnace heating element replacement, this guide is for you.
I’m Savvy Mavi, and in this article, we’ll take an in-depth look at the Goodman MBVK electric furnace, focusing on its heating elements and coils, how they work, common issues, replacement considerations, and maintenance tips to maximize lifespan. Along the way, I’ll explain related concepts for heat pumps, air handlers, and even gas furnaces where relevant, helping you see the big picture of home heating.
What Is a Heating Element?
A heating element is the component in your electric furnace that converts electricity into heat. It functions similarly to the coils in a toaster or electric oven. In HVAC systems, heating elements are often called heating coils, furnace elements, or furnace heating coils, depending on the context.
In the Goodman MBVK electric furnace, the heating elements are carefully staged to provide consistent, even heat. They work with the variable-speed blower to distribute warmth efficiently throughout your home.
Key functions of a heating element include:
-
Generating heat from electrical resistance
-
Working in conjunction with the blower motor to circulate warm air
-
Engaging in stages to prevent overheating and improve energy efficiency
Resources from the U.S. Department of Energy explain that electric resistance heating is nearly 100% efficient at the point of use, meaning all electricity consumed is converted into heat—no combustion, no exhaust, and no carbon monoxide.
Types of Heating Elements and Coils
Different HVAC systems utilize heating elements in slightly different ways:
Electric Furnace Heating Elements
In electric furnaces like the Goodman MBVK:
-
Elements are typically metal rods or coils
-
They heat in stages, allowing for precise control
-
Multiple elements can be energized simultaneously for larger heating loads
-
They are designed to last 10–20 years with proper maintenance
Heat Pump Heating Coils
Some systems combine electric heating elements with heat pumps. When outdoor temperatures are too low for the heat pump to provide sufficient warmth, electric backup heating coils engage.
AC Heater Coils
Certain air conditioners and heat pumps have integrated heating elements for AC units or heating element for air conditioner. These provide supplemental heat in cooling-dominant climates or when reverse cycle operation is needed.
Gas Furnace Heating Elements
While gas furnaces primarily rely on combustion, some modern hybrid systems include gas furnace heating elements for supplemental electric heat. Understanding this distinction helps avoid confusion when comparing furnace heating element replacement for different system types.
Common Issues with Furnace Heating Elements
Even high-quality components like those in the Goodman MBVK can experience issues over time. Common problems include:
1. Burned-Out Elements
Electric heating elements are metal and carry high voltage. Over time, they can burn out, leading to:
-
Electric furnace heating element blowing cool air
-
Partial or complete loss of heat
-
Increased energy usage as remaining elements compensate
2. Overheating
Restricted airflow can cause elements to overheat and trip safety limits. Symptoms include:
-
Intermittent heat
-
Blower running without heat
-
Furnace shutdowns requiring a reset
3. Corrosion or Scaling
In humid environments, metal elements can corrode, shortening lifespan. Proper installation, airflow management, and periodic inspection prevent most corrosion-related failures.
4. Electrical Issues
Loose connections, improper voltage, or failing relays can cause heating elements to malfunction. Professional inspection ensures safe and reliable operation.
When to Replace Furnace Heating Elements
Signs you may need furnace heating element replacement or electric furnace heating coil replacement:
-
No heat when the furnace blower runs
-
Uneven or intermittent heating
-
Burned or visibly damaged coils
-
Frequent tripping of safety switches
Replacement should always follow manufacturer specifications. Using compatible elements ensures safe operation and optimal performance. For guidance, the Goodman MBVK installation manual details element specifications and replacement procedures.
Furnace Heating Element Replacement Cost
The cost of replacing a furnace heating element depends on system type, labor, and element size:
-
Electric furnace heating elements: $100–$300 per element
-
Labor: $100–$250 depending on complexity and access
-
Total replacement: $200–$550 for a single-element system
For larger homes with multiple staged elements, costs can rise proportionally. Budgeting for replacement during regular maintenance helps prevent sudden heat loss during winter.
Maintenance Tips for Heating Coils
Maintaining furnace heating coils and electric furnace elements increases lifespan and improves efficiency:
-
Replace air filters regularly to maintain airflow
-
Inspect ductwork for blockages or leaks
-
Ensure thermostats and controls are correctly configured
-
Schedule annual inspections for all electric and hybrid heating systems
-
Clean or gently vacuum exposed heating coils to prevent dust accumulation
Energy Star provides guidance on HVAC maintenance practices, highlighting that preventive care extends element life and reduces repair costs.
Safety Considerations
Electric heating elements operate at high voltage and temperatures. Always follow these safety practices:
-
Turn off power before inspection or replacement
-
Use compatible replacement elements
-
Avoid touching heating coils with bare hands
-
Never bypass safety switches or limit controls
The Goodman MBVK includes multiple safety features designed to prevent overheating, protect elements, and maintain airflow. Ignoring these protections can result in reduced lifespan or hazards.
Integrating Heating Elements with Air Handlers and AC Units
Some modern HVAC systems integrate electric heating elements for air handlers or heating elements for AC units to provide supplemental or backup heat. In these systems:
-
Elements activate when the main heating source is insufficient
-
Blower speed and staging ensure even distribution
-
Proper maintenance and inspection prevent premature failure
Understanding this integration helps homeowners distinguish between electric heat and combustion-based heat, reducing confusion about system operation.
Signs You Need Professional Assistance
Certain issues warrant professional evaluation:
-
Furnace blower runs, but heat is absent
-
Visible damage to heating coils
-
Frequent tripping of safety or limit switches
-
Uneven or fluctuating temperatures
Certified HVAC technicians can safely replace electric furnace heating elements, furnace heating coils, or hybrid system components while ensuring compliance with safety standards.
Summary: Maximizing Comfort with Proper Heating Element Care
The Goodman MBVK electric furnace relies on well-designed heating elements and coils to deliver reliable warmth. Key takeaways:
-
Heating elements convert electricity to heat safely and efficiently
-
Proper airflow and maintenance are critical for performance
-
Replacement is straightforward but should follow manufacturer guidance
-
Safety switches and controls prevent overheating and extend element life
-
Costs for replacement are reasonable and predictable with planning
Whether you’re dealing with electric furnace heating coil replacement, furnace heating element replacement, or integrating supplemental heating with a heat pump or AC system, understanding these components is essential for consistent, reliable home heating.
With knowledge, preventive care, and occasional professional support, you can ensure that your Goodman MBVK keeps delivering warmth safely, efficiently, and reliably all winter long.
