Confused about furnace heating elements and heating coils? Tony Marino explains how electric furnace heating elements work, when replacement is needed, and why the Goodman MBVK electric furnace delivers reliable, efficient central electric heat.

Homeowners often describe modern HVAC setups as a “hot and cold air conditioner,” but that phrase hides how these systems actually work. Using the Goodman MBVK electric furnace as a real-world example, Mark Callahan explains how heaters and AC work together, why heat pumps rely on electric backup heat, and how today’s 2-in-1 heating and cooling systems deliver consistent comfort without the drama of older equipment.

Furnace wiring diagrams can look overwhelming, but understanding what they actually show makes modern systems far less intimidating. Using the Goodman MBVK electric furnace as a real-world example, Mark Callahan explains how electric furnace wiring diagrams differ from gas furnace schematics, how control board wiring manages heat and airflow, and why correct thermostat and safety wiring are critical to safe, reliable operation.

Many homeowners search for a Carrier furnace reset button when their heat stops working—only to discover their system doesn’t even use one. In this in-depth guide, Mark Callahan explains why reset-button advice from older Carrier gas furnaces doesn’t apply to modern electric systems like the Goodman MBVK, where safety controls, airflow, and power management replace manual resets. Understanding the difference is the fastest way to get your heat back on.

When your furnace won’t turn on, it’s easy to assume the worst—or chase the wrong fix. In this in-depth guide, Mark Callahan explains why furnaces fail to start, why gas-furnace advice doesn’t apply to electric systems like the Goodman MBVK, and what homeowners should check before calling for service. Understanding how an electric furnace protects itself is the key to solving the problem without unnecessary frustration.

How do heaters actually work—and why does electric heat feel different from gas or portable heaters? Using the Goodman MBVK electric furnace as a real-world example, Mark Callahan breaks down how heaters produce and distribute heat, how electric heaters and room heaters operate, and why understanding the working of heater systems helps homeowners know what’s normal, what’s efficient, and when something is actually wrong.

Is your air conditioner also your heater? If you’ve ever called your system a hot and cold AC or a 2-in-1 air conditioner and heater, you’re not alone. In this guide, Jake Lawson explains how heaters and AC work together, why electric systems feel different than gas, and how a Goodman MBVK electric furnace handles both heating and cooling through one system.

Looking at a furnace wiring diagram and not sure what you’re actually seeing? If you have a Goodman MBVK electric furnace, most online wiring diagrams can be misleading. In this guide, Jake Lawson breaks down electric furnace wiring, control boards, thermostat wiring, and how MBVK systems differ from gas furnace wiring—without the guesswork or dangerous DIY advice.

Searching for the Carrier furnace reset button but can’t find it on your system? If you have a Goodman MBVK electric furnace, that confusion makes sense. In this guide, Jake Lawson explains why Carrier gas furnaces have reset buttons, why MBVK electric furnaces don’t, and how to properly restart an electric heating system without chasing parts that aren’t there.

Furnace will not turn on—and you’re not sure why? If you have a Goodman MBVK electric furnace, the problem often isn’t what you think. In this guide, Jake Lawson explains why furnaces don’t turn on, how electric systems differ from gas furnaces, and what to check first before assuming your heating system has failed.

How do heaters work—and what’s the difference between a room heater and a whole-house electric furnace? In this guide, Jake Lawson breaks down how electric heaters work, from portable and room heaters to a Goodman MBVK electric furnace, explaining the simple physics behind electric heat and why it feels different from gas systems.
