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

November 24, 2020

Your garage can be more than just a place to park your vehicles in Anchorage. It can be a workshop, give additional storage and more. But when you’re spending more time out there, it needs to be a cozy temperature.

Garages don’t often have the ductwork necessary for regular heating and cooling systems. While you can install ductwork, it’s not the most advantageous option. The wisest approach to heat your garage is by having a ductless comfort system, like a mini-split system or a garage heater.

Let’s go over the difference between the two to help you discover the ideal solution for your needs.

What is a Mini-Split?

A mini-split is much like a heat pump since it moves heat rather than making it. This makes it a very energy-efficient heating and cooling system for areas that lack ductwork. These electric systems are often put on a wall and linked to the outdoor unit through a small hole in the wall.

Although a ductless mini-split is higher priced, many have achieved ENERGY STAR® designation for their energy efficiency. They’re also highly quiet and deliver zoned comfort, which gives exact control over your garage’s temp.

The majority of mini-splits allow you to link several indoor units to an individual outdoor unit. If your garage is part of your residence, you might be able to have additional indoor units in areas that are tricky 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 upper corner of a wall. Depending on the model, these heaters can run on electricity, gas or propane. They’re a great option if you are situated in a chilly climate and complete a lot of grubby dirty work. Garage heaters are heavy-duty and made to keep working through added grime.

Comparing Top Features of Garage Heaters and Mini-Splits

We’ve put together a handy guide to help you select the right system for your garage.


Garage heaters are the most economical option. The typical expense varies because of fuel type, but they’re usually about half the cost of a mini-split.

Operating Costs

Garage heaters work similarly to a furnace, consuming fuel to make heat. 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 even lower heating and cooling expenses if you choose an ENERGY STAR® certified model. And you might be eligible for added rebates as a result of that energy efficiency.

Fuel Source

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

Heating and Cooling

As its name indicates, a garage heater is limited to only offering heat. A ductless mini-split delivers both heating and cooling.

Precise Temperature Control

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

Space Considerations

Due to the fact garage heaters are often placed on the ceiling, they can consume valued overhead storage area. In contrast, slim mini-split systems are often put higher up on a wall and don’t need a lot of space.
