Applications

Spaces a Garage Mini-Split Can Cool

A mini-split cools a single space without tying into your home's central system. You set the temperature independently, so you only pay to cool the space you are using.

Garages

Cool your garage so you can use it year-round, not just in winter.

Workshops

Keep tools, electronics, and project spaces at a workable temperature.

Home Gyms

Train in comfort without the heat exhaustion that comes with a 120-degree garage.

Man Caves

Turn your garage into a lounge, media room, or entertainment space.

Additions

Cool a room addition or converted space without running new ductwork.

Rooms Without Ductwork

Bring cooling to casitas, guest rooms, and outbuildings with no central air.

Sizing

Arizona Garage Sizing Explained

Garages need more cooling per square foot than living space in Arizona. Sun exposure, insulation, and ceiling height all change the load. We confirm the correct size during your free estimate.

One-Car Garage

18,000 BTU

A single-car garage usually needs a smaller unit, but sun exposure and insulation still affect the load.

Two-Car Garage

24,000 BTU

The most common Phoenix garage size. A 2-ton unit handles most two-car garages with standard ceiling height.

Three-Car Garage

30,000+ BTU

Larger garages, especially with west-facing doors, often need a larger system or a second zone.

Insulation and Garage Door Considerations

  • Attic insulation reduces the cooling load and helps the system hold a steady temperature.
  • An insulated garage door helps, especially on west- and south-facing doors.
  • We assess your garage during the estimate and tell you whether insulation makes sense.

Electrical Distance and Voltage

  • Standard installation includes electrical connection up to 20 feet from the panel.
  • Longer runs or new circuits are priced separately and shown on your quote.
  • Most garage mini-splits run on 220V. Smaller units may use 115V.
