How Mini Splits Work

A mini split, or ductless system, is an efficient way to heat or cool specific areas of a home. Unlike central systems which distribute air through ducts, mini splits use wall-mounted units connected to an outside condenser.

Mini splits operate just like heat pumps, using electricity and the heat transfer process. In the winter, they take the small amount of heat in the air outside, increase that heat, and then pump it into your home. In the summer, the process is reversed, taking the heat from your home, pumping it outside, and bringing cooler air in.

Single-Zone Systems

Specifically for this guide, we’re focusing on single-zone systems, which cater to individual rooms. A mini split for a garage typically involves a single-zone system, given the isolated nature of garages. This is the same as sunrooms, additions, and attics. We’ll get to more of that later.

Advantages Of A Mini Split In The Garage

The advantages of using a mini split garage system are simple, but noticeable:

1. Efficiency: They avoid the energy losses associated with ductwork, reducing energy consumption. They also operate more efficiently than most traditional HVAC systems.
2. Flexibility: You can install mini split in garage spaces where traditional HVAC might not reach. No ductwork is needed either.
3. Quiet Operation: Can I put a mini split in my garage and still have peace? Absolutely, as they operate with minimal noise. These are some of the quietest HVAC systems available.

Cost to Install A Mini Split In A Garage

The cost to install mini split in garage areas can vary based on a few factors. Typically, the price is between $3200 – $5000 for a mini split in a garage.

Professional Vs. DIY Garage Mini Split Installation

While some individuals might opt for DIY, hiring a professional ensures that the mini split garage system is installed safely and efficiently. Installing the system yourself may save some money, but it also may void the warranty on your system, and cause problems down the line. We recommend using a pro!

Sizing Your Mini Split

It’s crucial to size the mini split for a garage correctly to guarantee efficiency. An undersized unit won’t effectively cool or heat, while an oversized one could lead to short-cycling. Your contractor should be able to fit you with the right-sized system.

What Installation Is Like

When you decide to install a mini split in garage spaces, the process typically involves mounting the indoor unit on a wall, drilling a hole to connect the refrigerant lines, and setting up the external condenser. It can take a few hours to a day, depending on complications. A single zone usually doesn’t have too long of an installation time.

More Uses For a Single-Zone Ductless System

While we’ve highlighted the benefits of a mini split for a garage, these systems are versatile and can be used in various areas.

Mother-In-Law Suites

An excellent solution for guest spaces, ensuring your in-laws or visitors have a comfortable stay. This also allows your guest to control their own temperature.

Sunrooms

These rooms can get particularly cold or hot depending on the season. A mini split ensures year-round comfort. A mini split also doesn’t require any additional ductwork.

Bedrooms

For a tailored sleeping climate, installing a mini split in bedrooms offers individual temperature control.
