Ductless Mini-Splits: The Best Way to Heat and Cool Your Garage
If you spend any time in your garage, you already know the problem. In the middle of a Tennessee summer, it turns into an oven. In January, it feels like a freezer. A ductless mini-split for your garage solves both problems with one simple system.
At Efficient Heating & Cooling, we install ductless mini-splits for homeowners across Lebanon, Nashville and Middle Tennessee. Here’s how they work and why they’re such a good fit for garages.
The Problem: Your Garage Isn’t Connected to Your Home’s System
Most garages aren’t connected to the home’s ductwork. Your central heating and air keeps the rest of the house comfortable, but the garage is left out. That’s why garages are freezing in the winter and sweltering in a Tennessee summer.
Running new ductwork into a garage is usually expensive and inefficient, and portable heaters or fans rarely keep up.
What Is a Ductless Mini-Split?
A ductless mini-split has two main parts:
- An outdoor unit, which sits outside your home, like the Mitsubishi unit pictured above
- A slim indoor unit, mounted high on the garage wall
The two are connected by a small line that runs through the wall. There’s no ductwork involved. The indoor unit heats or cools the air in your garage and blows it back into the space.
Why a Mini-Split Works So Well for Garages
Heats and cools in one system
You don’t need a separate space heater for the winter and a portable AC for the summer. One mini-split handles both.
No ductwork to install
Because the system is ductless, there’s no need to run ducts through your attic or walls. Installation is cleaner and simpler.
Quiet and energy-efficient
Mini-splits run quietly and efficiently. Since the garage has its own system, you only heat or cool it when you’re actually using it, without affecting the rest of your home.
Frees up floor space
Unlike a portable unit or space heater, the indoor unit mounts high on the wall, keeping your floor clear for tools, vehicles and equipment.
What a Garage Mini-Split Is Great For
A ductless mini-split is a great choice if your garage is used as a:
- Workshop
- Home gym
- Man cave
- Hobby space
- Extra living space
