At DM Cold Air, we often speak with homeowners in Boca Raton who are looking for ways to make better use of their garage. Whether it’s for a home gym, a workshop, or even just to protect storage from the intense Florida heat, one question comes up again and again:
“Can I install a garage AC unit?”
The short answer is yes—and in South Florida, it might be one of the smartest upgrades you can make to your home.
In this post, we’ll explain what a garage AC unit is, how it works, what your options are, and what you should consider before installation. If you’re thinking about turning your garage into a more functional, livable space, this guide is for you.
Why Cool Your Garage?
Your garage likely wasn’t designed to be air-conditioned. In most homes, it’s a closed-off space with no ductwork, insulation, or ventilation. But if you’re using it for more than just parking, the lack of cooling can be a problem.
Adding a garage AC unit can help:
- Improve comfort if you’re spending time in the space
- Protect valuable items like tools, electronics, and storage boxes from heat and humidity
- Reduce indoor heat that radiates into adjoining rooms
- Prevent mold and mildew from forming in poorly ventilated garages
In hot and humid climates like Boca Raton, garages can reach temperatures well above 100°F—especially during summer. That kind of heat doesn’t just make the space uncomfortable; it can also cause long-term damage to anything you store inside.
Common Uses for a Garage AC Unit
A garage AC unit isn’t just for people who want to make their garage “fancy.” It’s practical for many real-life uses, including:
- Home gyms
- Hobby or craft rooms
- Workshops
- Office spaces
- Game rooms or lounges
- Temperature-sensitive storage
If your garage is part of your daily routine, adding a cooling solution can increase its usability—and your overall quality of life at home.
What Are Your Cooling Options?
When it comes to cooling your garage, there’s no single solution. The best system depends on how large your garage is, how often you use it, and what your goals are.
Here are the most common types of garage AC units we install for customers in South Florida:
1. Ductless Mini-Split Systems
Ductless mini-split systems are ideal for garages because they don’t require connection to your home’s central air system. They consist of one indoor unit (mounted on the wall) and one outdoor compressor unit. Mini-splits are energy-efficient, quiet, and provide powerful cooling for garages of all sizes.
They’re perfect if you want a long-term, reliable solution that offers consistent temperature control year-round.
2. Window AC Units
A window AC unit can work well if your garage has a suitable window or can be modified to accommodate one. These are more affordable than ductless systems, but they don’t offer the same level of efficiency or control. They also take up window space and can be a bit noisy.
3. Through-the-Wall AC Units
Similar to window units but installed directly into a wall, these systems provide decent cooling without using up window space. They require more installation work, but they’re effective and relatively affordable for single-room spaces like a garage.
4. Portable AC Units
Portable air conditioners are freestanding units that require venting through a door or window. They’re easy to install and move, but they’re less powerful and efficient than fixed options. These are best suited for small garages or short-term use.
Why Not Extend Your Central AC?
It might seem logical to simply extend your home’s central air system into the garage, but in most cases, it’s not the best option—and may even violate local building codes. Garages often store chemicals, gas, and car exhaust. Connecting them to your central HVAC system can pull dangerous fumes into your home.
Instead, a standalone garage AC unit is safer, more efficient, and easier to control independently.
Important Factors to Consider Before Installation
Installing a garage AC unit requires more than just picking out a product. At DM Cold Air, we walk you through every step to ensure the solution fits your space and your lifestyle.
Here’s what we consider before making a recommendation:
1. Insulation
If your garage isn’t insulated, cooling it will be much harder and more expensive. We often advise customers to add basic insulation to the garage door, ceiling, and walls before installing an AC system. It helps the unit perform better and keeps energy costs down.
2. Garage Size
We take precise measurements to determine the right unit size for your space. Installing a unit that’s too small will overwork the system, while one that’s too large may cool unevenly and waste energy.
3. Electrical Capacity
Some garage AC units, especially mini-splits and through-the-wall systems, may require a dedicated electrical circuit. We’ll evaluate your current setup and let you know if upgrades are needed before installation.
4. Ventilation
Cooling your garage is just one part of the equation—removing excess humidity is just as important. We’ll ensure proper airflow and humidity control so the space stays comfortable and safe.
