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 Lake Worth. It can be an area to work, offer additional storage and more. But when you’re working out there more often, it needs to be a comfy temperature.

Garages don’t usually have the ductwork needed for common heating and cooling systems. While you can add ductwork, it’s not the most advantageous remedy. The wisest approach to heat your garage is by adding 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 similar to a heat pump as it shifts heat as opposed to creating it. This makes it a highly energy-efficient heating and cooling system for spaces that don’t have ductwork. These electric systems are usually placed on a wall and joined to the outdoor unit through a tiny hole in the wall.

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

Most mini-splits allow you to connect multiple indoor units to a single outdoor unit. If your garage is adjacent to your home, you may be able to have added indoor units in rooms that are tricky to heat and cool.

What is a Garage Heater?

A garage heater is better than a space heater. This all-in-one heating solution is installed 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 option if you are situated in a northern climate and complete a lot of dusty dirty work. Garage heaters are heavy-duty and designed to last through extra grime.

Evaluating Notable Features of Garage Heaters and Mini-Splits

We’ve created a valuable guide to help you choose the right system for your garage.


Garage heaters are the most economical solution. The average cost is different because of fuel type, but they’re typically about half the cost of a mini-split.

Operating Costs

Garage heaters are similar to a furnace, using fuel to generate hot air. A mini-split air conditioner is nearer to a heat pump, which shifts warmth. This makes a mini-split more efficient to use. You’ll have decreased utility bills if you choose an ENERGY STAR® certified model. And you may be entitled to added rebates as a result of that energy efficiency.

Fuel Source

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

Heating and Cooling

As its title says, a garage heater is restricted to just providing heat. A ductless mini-split delivers both heating and cooling.

Precise Temperature Control

When you are looking for the most accurate comfort control, a mini-split heat pump is the smartest option because it delivers 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 placed on the ceiling, they can take up premium overhead storage area. In contrast, slim mini-split systems are often installed higher up on a wall and don’t require a lot of space.
