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

November 24, 2020

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

Garages don’t often have the ductwork required for regular heating and cooling systems. While you can install ductwork, it’s not the most advantageous option. The best approach to heat your garage is by having 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 ideal solution for your needs.

What is a Mini-Split?

A mini-split is close to a heat pump because it moves heat instead of creating it. This makes it an extremely energy-efficient heating and cooling system for spaces that don’t have ductwork. These electric systems are typically put on a wall and connected to the outdoor unit through a small hole in the wall.

Though a ductless mini-split is more expensive, many have earned ENERGY STAR® designation for their energy efficiency. They’re also very quiet and provide zoned comfort, which offers exact control over your garage’s temperature.

Many mini-splits allow you to link multiple indoor units to a single outdoor unit. If your garage is adjacent to your residence, you might be able to install added indoor units in spaces that are tricky to heat and cool.

What is a Garage Heater?

A garage heater isn’t a space heater. This comprehensive heating solution is placed on the ceiling or the high corner of a wall. Depending on the model, these heaters can run on electricity, gas or propane. They’re an excellent option if you live in a cold climate and complete a lot of dusty dirty work. Garage heaters are heavy-duty and created to keep working through added grime.

Comparing Key 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 lowest-priced solution. The estimated expense differs based on fuel type, but they’re typically 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 more similar to a heat pump, which shifts warmth. This makes a mini-split more efficient to run. You’ll get even lower utility bills if you choose an ENERGY STAR® certified model. And you could be eligible for extra rebates because 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 title indicates, a garage heater only provides delivering heat. A ductless mini-split provides both heating and cooling.

Precise Temperature Control

When you want the most exact comfort control, a mini-split heat pump is the best answer because it offers zoned heating and cooling. That way, your garage will be just the 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, space-saving mini-split systems are often installed higher up on a wall and don’t have to have a lot of real estate.
