Choose A Mini Split For A Garage: Ultimate Homeowner’s Guide

Most garages are designed without heating and air conditioning in mind. It’s typically a storage space, and one that people don’t spend time in. But, if you DO want to use your garage as a workspace, a living space, maybe an office, you’ll want to have it comfortable all year long. We recommend a mini split for a garage in Brevard, NC to keep it cool in the summer, and warm in the winter.

I have worked in all sorts of homes in the area, and in my years, I’ve seen more and more homeowners turn their garage into a comfortable living space. We recommend a garage mini split to moderate the temperature, and insulation to help maintain it. Without proper insulation, this can waste energy and lead to discomfort even with a mini split.

How Mini Splits Work

Ductless mini split systems have become increasingly popular for their efficiency and ease of installation. Unlike traditional HVAC systems, mini splits do not require extensive ductwork. Instead, they consist of an outdoor condenser connected to one or more indoor units via small conduits. These systems offer both heating and cooling, making them great to use as supplements for sunrooms, bedrooms, basements, and garages!

Single-Zone Vs. Multi-Zone

When it comes to keeping your garage comfortable, you will almost definitely only need a single-zone system. Ductless mini splits are broken down into zones, and can be spread around your home. For most garages, a single zone should do the trick, but you can always add zones around the home if you choose to do so. This is a great way to save energy, and customize the comfort around your home. You could have one bedroom at 73, another at 68, and the garage turned off to save energy.

Average Cost to Install a Mini Split in The Garage

The cost of installing a mini split in a garage can vary based on a few factors. What brand and model you decide to install, how energy efficient it is, and the layout of the garage all factor into the cost. At Blue Ridge heating and air conditioning, the cost of a ductless mini split installation starts around $4900 and goes from there. Luckily, there are rebates and tax credits usually available for energy efficient equipment like ductless mini splits.

Can I Put A Mini Split In My Garage?

Yes, you can install a mini split in your garage. As we mentioned, most garages are designed without heating and cooling in mind. The ducts don’t reach there, and it’s typically not insulated like the rest of the home. By choosing a mini split for your garage, you can create a comfortable environment for more long term activities in the garage, like using it as a home gym, or a workspace.

Why A Mini Split In A Garage Is Worth It

Ductless mini splits are perfect for a garage, especially if you want to use it all year long. These systems both heat and cool. A window AC is almost impossible as most garages don’t have windows, and that only works for the summer anyways.

A ductless mini split in your garage will also add value to the home. It’s a significant investment, and one that expands the livable space a home has. If you decide to sell or rent your home, this should help with the price tag.

Professional Vs. DIY Garage Mini Split Installation

While some homeowners may consider DIY installation to save costs, professional installation is recommended for a mini split system. Professionals ensure proper setup, maximizing efficiency and lifespan, and also have the permits and licenses you need to work with some of this equipment.

A professional can also help you select the right model for your specific needs and garage size, while getting the best discounts available.

What To Expect The Day You Install A Mini Split In Your Garage

On the day of installation, the professional will mount the indoor unit, connect it to the outdoor unit, and ensure everything is functioning correctly. The process typically takes a few hours, depending on the complexity of the installation. A single zone system like this should be a fairly simple task to complete.

Other Single-Zone Ductless Applications

Besides garages, mini splits are also suitable for other single-zone applications. They are perfect for spaces where traditional ducted systems are impractical or too expensive to install. We’ve installed plenty of whole home solutions when it comes to mini splits, but there are also cases where we add a mini split as a supplement somewhere around the house.


Sunrooms often require independent temperature control due to their extensive glass exposure. They are also usually an addition to a home, built after the original HVAC system was installed. A mini split can provide efficient heating and cooling in these spaces.
