Mini Splits vs. Garage Heaters: What Should I Install in My Garage?

November 24, 2020

Your garage can be more than just a space to put your vehicles in Wyandotte. It can be a work space, offer extra storage and more. But when you’re working out there more often, it needs to be a comfortable temperature.

Garages don’t often have the ductwork needed for common heating and cooling systems. While you can add ductwork, it’s not the most cost-effective option. The best way to heat your garage is by using a ductless comfort system, like a mini-split system or a garage heater.

Let’s review the difference between the two to help you discover the ideal style for your needs.

What is a Mini-Split?

A mini-split is much like a heat pump as it transfers heat instead of creating it. This makes it a highly energy-efficient heating and cooling system for rooms that lack ductwork. These electric systems are usually placed on a wall and linked to the outdoor unit through a little hole in the wall.

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

The majority of mini-splits allow you to connect multiple indoor units to a single outdoor unit. If your garage is part of your residence, you may be able to have added indoor units in areas that are difficult to heat and cool.

What is a Garage Heater?

A garage heater is more than a space heater. This all-encompassing heating solution is placed 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 good option if you reside in a cold climate and complete a lot of grubby dirty work. Garage heaters are heavy-duty and designed to withstand extra grime.

Comparing Top Features of Garage Heaters and Mini-Splits

We’ve assembled a useful guide to help you pick the right system for your garage.


Garage heaters are the most budget-friendly solution. The estimated price is different because of fuel type, but they’re frequently about half the cost of a mini-split.

Operating Costs

Garage heaters are much like a furnace, consuming fuel to create hot air. A mini-split air conditioner is more like a heat pump, which moves heat. This makes a mini-split more efficient to use. You’ll enjoy even lower energy bills if you select an ENERGY STAR® certified model. And you may be eligible for added rebates because of that energy efficiency.

Fuel Source

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

Heating and Cooling

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

Precise Temperature Control

When you are seeking the most accurate temp control, a mini-split heat pump is the best option since it delivers zoned heating and cooling. That way, your garage will be the exact temperature you want it to be.

Space Considerations

Because garage heaters are usually mounted on the ceiling, they can take up premium overhead storage area. In comparison, low-profile mini-split systems are typically installed higher up on a wall and don’t need a lot of room.
