How much does it cost to install a mini-split in a garage in Arizona?

A mini-split for a 2-car garage in Arizona costs $6,516-$7,721 installed at Bradford (Mitsubishi 24,000 BTU MSZ-GX). This includes equipment, labor, 240V circuit, and line set up to 15 ft. Electric extra if the panel is more than 15 ft away.

Is a mini-split worth it for an Arizona garage?

Yes - for a garage that's used regularly (workshop, gym, home office), a mini-split is the most cost-effective solution. It doesn't require ductwork, cools only the space you're using, and can also provide heat in winter. The 24,000 BTU system pays for itself in 3-5 years compared to a window unit.

Can a mini-split cool a 3-car garage in Arizona?

A single 36,000 BTU mini-split can cool a 3-car garage (750 sq ft) if it has some insulation. For a fully uninsulated 3-car garage, Bradford recommends adding insulation first or using two 24,000 BTU units. Call (623) 624-6246 for a free assessment.

Arizona Garage Sizing Guide

Arizona garages need more BTUs than the standard rule because they're typically uninsulated and face extreme heat. Bradford's rule: 200 sq ft per ton for uninsulated garages, 300 sq ft per ton for partially insulated, 400 sq ft per ton for fully insulated. 1-car garage (~250 sq ft, uninsulated): 15,000 BTU. 2-car garage (~500 sq ft, uninsulated): 24,000 BTU. 3-car / RV garage (~750-1,000 sq ft): 36,000 BTU.

Why Mitsubishi?

Bradford installs Mitsubishi Electric mini-splits exclusively. Mitsubishi is the #1 mini-split brand in North America and has the best reliability record in extreme heat. The MSZ-GX series is rated for operation up to 115F outdoor temperature - essential for Arizona summers.
