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

November 24, 2020

Your garage can be more than just a place to store your vehicles in Boynton Beach. It can be an area to work, provide additional storage and more. But when you’re spending more time out there, it needs to be a comfortable temperature.

Garages don’t usually have the ductwork necessary for regular heating and cooling systems. While you can install ductwork, it’s not the most cost-effective solution. The best way 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 choose the right solution for your needs.

What is a Mini-Split?

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

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

Most mini-splits allow you to connect multiple indoor units to a single outdoor unit. If your garage is part of your home, you might be able to install additional indoor units in spaces 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 mounted on the ceiling or the high corner of a wall. Depending on the model, these heaters can use electricity, gas or propane. They’re an excellent option if you reside in a cold climate and do a lot of dirty dirty work. Garage heaters are heavy-duty and made to last through extra grime.

Evaluating Top Features of Garage Heaters and Mini-Splits

We’ve assembled a useful guide to help you pick the ideal system for your garage.


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

Operating Costs

Garage heaters are similar to a furnace, needing fuel to make warmth. A mini-split air conditioner is closer to a heat pump, which moves heat. This makes a mini-split more efficient to use. You’ll get even lower energy costs if you select an ENERGY STAR® certified model. And you could have access to additional rebates as a result of that energy efficiency.

Fuel Source

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

Heating and Cooling

As its title indicates, a garage heater is limited to only providing 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 answer because it provides zoned heating and cooling. That way, your garage will be the right temperature you want it to be.

Space Considerations

Since garage heaters are usually installed on the ceiling, they can consume premium overhead storage room. In comparison, low-profile mini-split systems are often installed higher up on a wall and don’t need a lot of real estate.
