Mini Splits vs. Garage Heaters: Whats Right for My Garage?

November 24, 2020

Your garage can be more than just an area to store your vehicles in Perry. It can be a work space, provide added storage and more. But when you’re out there more often, it needs to be a comfy temperature.

Garages don’t usually have the ductwork needed for regular heating and cooling systems. While you can install ductwork, it’s not the most economical option. The smartest way to heat your garage is by using a ductless comfort system, like a mini-split system or a garage heater.

Let’s discuss the difference between the two to help you choose the best option for your needs.

What is a Mini-Split?

A mini-split is close to a heat pump since it shifts heat as opposed to generating it. This makes it a very energy-efficient heating and cooling system for rooms without ductwork. These electric systems are typically installed on a wall and connected to the outdoor unit through a tiny hole in the wall.

Although a ductless mini-split costs more, a lot have earned ENERGY STAR® certification for their energy efficiency. They’re also extremely quiet and deliver zoned comfort, which offers accurate control over your garage’s temperature.

The majority of mini-splits allow you to connect more than one indoor unit to one outdoor unit. If your garage is connected to your residence, you might be able to install additional indoor units in spaces that are hard to heat and cool.

What is a Garage Heater?

A garage heater isn’t a space heater. This all-in-one heating solution is mounted on the ceiling or the higher corner of a wall. Depending on the model, these heaters can run on electricity, gas or propane. They’re a great option if you live in a chilly climate and perform a lot of grubby dirty work. Garage heaters are heavy-duty and created to withstand added grime.

Evaluating Top Features of Garage Heaters and Mini-Splits

We’ve made a handy guide to help you pick the ideal system for your garage.


Garage heaters are the most budget-friendly option. The typical cost differs based on fuel type, but they’re often about half the cost of a mini-split.

Operating Costs

Garage heaters are much like a furnace, needing fuel to create hot air. A mini-split air conditioner is closer to a heat pump, which shifts hot air. This makes a mini-split more efficient to use. You’ll get reduced utility bills if you get an ENERGY STAR® certified model. And you could have access to added rebates because of that energy efficiency.

Fuel Source

Garage heaters have the widest options for fuel sources—electricity, gas or propane. Mini-splits are electric.

Heating and Cooling

As its designation suggests, a garage heater is restricted to just offering heat. A ductless mini-split offers both heating and cooling.

Precise Temperature Control

When you are looking for the most accurate temperature control, a mini-split heat pump is the smartest option as it delivers zoned heating and cooling. That way, your garage will be just the temperature you want it to be.

Space Considerations

Since garage heaters are usually placed on the ceiling, they can take up premium overhead storage room. On the other hand, space-saving mini-split systems are typically installed higher up on a wall and don’t require a lot of room.
