Man and Son Working in a Garage

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

Your garage can be more than just an area to put your vehicles in Oxford. It can be a workshop, offer added storage and more. But when you’re spending more time out there, it needs to be a cozy temperature.

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

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

What is a Mini-Split?

A mini-split is close to a heat pump since it moves heat as opposed to generating it. This makes it an extremely energy-efficient heating and cooling system for rooms that don’t have ductwork. These electric systems are often put on a wall and joined to the outdoor unit through a little hole in the wall.

Although a ductless mini-split costs more, a lot have achieved ENERGY STAR® designation for their energy efficiency. They’re also highly quiet and offer zoned comfort, which offers exact control over your garage’s climate.

The majority of mini-splits allow you to link more than one indoor unit to a single outdoor unit. If your garage is adjacent to your home, you may be able to use extra 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 installed on the ceiling or the high corner of a wall. Depending on the model, these heaters can consume electricity, gas or propane. They’re an excellent solution if you are situated in a northern climate and do a lot of dusty dirty work. Garage heaters are heavy-duty and designed to withstand extra grime.

Reviewing Top Features of Garage Heaters and Mini-Splits

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


Garage heaters are the lowest-priced solution. The average cost is different based on fuel type, but they’re usually about half the cost of a mini-split.

Operating Costs

Garage heaters are similar to a furnace, using fuel to make heat. A mini-split air conditioner is nearer to a heat pump, which moves warmth. 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 may be entitled to additional rebates because of that energy efficiency.

Fuel Source

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

Heating and Cooling

As its title indicates, a garage heater only provides providing heat. A ductless mini-split delivers 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 answer as it offers zoned heating and cooling. That way, your garage will be the exact temperature you want it to be.

Space Considerations

Because garage heaters are often installed on the ceiling, they can take up premium overhead storage area. In comparison, space-saving mini-split systems are typically placed higher up on a wall and don’t need a lot of space.
