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 Huntsville. It can be a work space, provide added storage and more. But when you’re working out there more often, it needs to be a comfortable temperature.

Garages don’t typically have the ductwork required for regular heating and cooling systems. While you can install ductwork, it’s not the most advantageous option. The wisest method to heat your garage is by having a ductless comfort system, like a mini-split system or a garage heater.

Let’s go through the difference between the two to help you discover the ideal style for your needs.

What is a Mini-Split?

A mini-split is close to a heat pump as it transfers heat instead of generating it. This makes it a very energy-efficient heating and cooling system for rooms that lack ductwork. These electric systems are usually installed on a wall and connected to the outdoor unit through a small hole in the wall.

Though a ductless mini-split is higher priced, 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 link several indoor units to a single outdoor unit. If your garage is adjacent to your home, you could be able to install extra indoor units in spaces that are difficult to heat and cool.

What is a Garage Heater?

A garage heater is better than a space heater. This comprehensive 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 a great option if you reside in a chilly climate and do a lot of grubby dirty work. Garage heaters are heavy-duty and made to last through added grime.

Reviewing Top Features of Garage Heaters and Mini-Splits

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


Garage heaters are the most economical option. The average price 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 make hot air. A mini-split air conditioner is closer to a heat pump, which transfers hot air. This makes a mini-split more efficient to operate. You’ll get reduced utility bills if you get an ENERGY STAR® certified model. And you might be eligible for extra rebates because of that energy efficiency.

Fuel Source

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

Heating and Cooling

As its title indicates, a garage heater is restricted to just delivering heat. A ductless mini-split provides both heating and cooling.

Precise Temperature Control

When you want the most exact temperature control, a mini-split heat pump is the smartest option since it delivers zoned heating and cooling. That way, your garage will be the right temperature you want it to be.

Space Considerations

Because garage heaters are typically placed on the ceiling, they can take up valued overhead storage space. On the other hand, slim mini-split systems are often put higher up on a wall and don’t need a lot of space.
