Best mini split AC for garage: Top 3 picks to keep your workspace cool

Mini split air conditioners are a great choice for keeping your garage cool and comfortable. They offer powerful cooling without the need for ductwork, making them easy to install in most garage spaces. The best mini split AC for a garage is typically a 12,000 to 24,000 BTU unit with a high SEER rating for energy efficiency.

These ductless systems can both cool and heat your garage, giving you year-round comfort. Top models like the Senville LETO Series and MrCool DIY 3rd Generation offer excellent performance. They provide effective temperature control while keeping energy costs low.

When choosing a mini split for your garage, consider the size of the space and your climate. Larger garages may need more powerful units up to 30,000 BTU. Look for features like variable-speed compressors and WiFi connectivity for added convenience. With the right mini split, you can turn your garage into a comfortable workspace or hangout spot.

Choosing the Right Mini Split for Your Garage

Picking the best mini split AC for your garage depends on a few key factors. Size, efficiency ratings, and installation options all play important roles in making the right choice.

Understanding BTUs and SEER Ratings

BTUs measure how much cooling power an AC unit has. For garages, you typically need about 20 BTUs per square foot. SEER ratings show how energy-efficient a unit is. Higher SEER numbers mean better efficiency and lower energy bills.

Most garage mini splits have SEER ratings between 16 and 20. Some high-end models can reach up to 30 SEER. When shopping, look for units with at least 16 SEER to balance cost and efficiency.

Remember that higher SEER units cost more upfront but save money over time. Think about how often you’ll use the AC when deciding how much to spend on efficiency.

Comparing Garage Sizes and Air Conditioner Capacities

Garage size is crucial in picking the right mini split capacity. Here’s a quick guide:

• 1-car garage (240 sq ft): 6,000-9,000 BTUs
• 2-car garage (400 sq ft): 9,000-12,000 BTUs
• 3-car garage (600 sq ft): 12,000-18,000 BTUs

These are rough estimates. Factors like insulation, sunlight exposure, and climate can change your needs. It’s better to slightly oversize than undersize your unit.

For larger garages (4+ cars), you might need multiple units or a single high-capacity system. Some models offer up to 36,000 BTUs, suitable for spaces around 1,200 square feet.

Installation Insights: DIY vs Professional

Many mini splits come with DIY installation kits. These can save money but require some handyman skills. DIY-friendly units often have pre-charged lines and simple mounting systems.

Professional installation costs more but ensures proper setup. Pros can handle tricky parts like electrical work and refrigerant charging. They also often offer warranties on their work.

Consider your skills and budget when deciding. DIY can save $500-$2000, but mistakes can be costly. Professional installation usually takes 4-8 hours and includes system testing.

Some brands, like Mr. Cool, specialize in easy-to-install DIY units. Others may void warranties if not installed by certified techs. Always check warranty terms before deciding on DIY or pro installation.
