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

November 24, 2020

Your garage can be more than just a place to store your vehicles in Grand Prairie. It can be a workshop, offer additional storage and more. But when you’re working out there more often, it needs to be a cozy temperature.

Garages don’t usually have the ductwork necessary for standard heating and cooling systems. While you can add ductwork, it’s not the most economical remedy. The wisest 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 discover the ideal option for your needs.

What is a Mini-Split?

A mini-split is similar to a heat pump because it shifts heat as opposed to making it. This makes it an extremely energy-efficient heating and cooling system for areas that lack ductwork. These electric systems are typically put 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 achieved ENERGY STAR® certification for their energy efficiency. They’re also highly quiet and provide zoned comfort, which provides accurate control over your garage’s temp.

The majority of mini-splits allow you to link several indoor units to a single outdoor unit. If your garage is part of your house, you may be able to install additional indoor units in spaces 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 mounted on the ceiling or the higher corner of a wall. Depending on the model, these heaters can use electricity, gas or propane. They’re a great choice if you are situated in a chilly climate and do a lot of dirty dirty work. Garage heaters are heavy-duty and designed to stand up to additional grime.

Comparing Top Features of Garage Heaters and Mini-Splits

We’ve put together a valuable guide to help you pick the ideal system for your garage.


Garage heaters are the most budget-friendly solution. The average cost varies because of fuel type, but they’re usually about half the cost of a mini-split.

Operating Costs

Garage heaters are similar to a furnace, needing fuel to make hot air. A mini-split air conditioner is nearer to a heat pump, which transfers hot air. This makes a mini-split more efficient to use. You’ll get even lower energy bills if you select an ENERGY STAR® certified model. And you might be eligible for extra 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 title suggests, a garage heater only provides providing heat. A ductless mini-split provides both heating and cooling.

Precise Temperature Control

When you are seeking the most exact temp control, a mini-split heat pump is the wisest solution because it offers zoned heating and cooling. That way, your garage will be just the temperature you want it to be.

Space Considerations

Due to the fact garage heaters are often mounted on the ceiling, they can take up valuable overhead storage space. On the other hand, low-profile mini-split systems are usually placed higher up on a wall and don’t require a lot of real estate.
