A mini split is a ductless air conditioning and heating system with two main parts: an outdoor condenser and one or more indoor air handlers (called heads). The indoor heads mount on a wall or ceiling and connect to the outdoor unit through a small line set that runs through a 3-inch hole in the wall. Mini splits work great for spaces that don't have ductwork, like garages, casitas, ADUs, sunrooms, and home additions. They also work great as supplemental cooling for rooms that the central system can't reach effectively. Modern mini splits use inverter technology and run at 18 to 30 SEER, which means they use significantly less electricity than traditional central AC.
We visit your space, evaluate the area you want to cool or heat, identify the best location for the indoor head(s), and check for outdoor condenser placement.
We calculate proper BTU sizing for the space using Manual J methodology, then recommend single zone or multi zone configuration. For multi-zone, we plan which rooms get which indoor heads.
We mount the indoor head(s), set the outdoor condenser on a proper pad or wall bracket, run the line set through the wall, install the condensate drain, and complete electrical hookup to code.
We pressure test the line set for leaks, vacuum the lines to remove moisture and air, charge the system with refrigerant, and verify cooling and heating performance at each indoor head.
We show you how to operate the remote(s) and any Wi-Fi controls, register your manufacturer warranty, and explain basic filter maintenance to keep the system running clean.
Phoenix garages are some of the hottest livable spaces in the country. Without cooling, an uninsulated Chandler garage can hit 130 to 140 degrees in July. A mini split sized for the space handles it easily, and the inverter tech means efficient operation even at peak heat. Mini splits are also the most cost-effective way to add cooling to a casita, ADU, sunroom, or home addition where extending ductwork would be expensive or impossible. Many East Valley homeowners use them for converted offices and gym spaces too. Energy efficiency matters in Arizona, and a 22+ SEER mini split costs significantly less to run than a central system trying to push cool air to a far-corner room.
Rush HVAC Services installs mini split systems throughout the East Valley and greater Phoenix area:

Mini split installation in Arizona typically runs $3,500 to $12,000 depending on capacity, number of zones, brand, and install complexity. A single zone system (9,000 to 24,000 BTU) for a garage or single room usually runs $3,500 to $6,500 installed. Multi zone systems with 2 to 3 indoor heads run $6,500 to $12,000. Premium brands like Mitsubishi Hyper-Heat or Daikin top-tier units cost more but offer better efficiency and longer warranties. Rush HVAC provides free in-home estimates with flat, written quotes.

Yes. Properly sized mini splits handle Arizona garage heat easily. For a typical 2-car garage, 18,000 to 24,000 BTU usually does the job. Insulation quality affects sizing, and we evaluate that during the estimate.
Single zone cools one space with one indoor head. Multi zone has one outdoor unit connected to 2 to 5 indoor heads in different rooms. Pick single zone for a garage, casita, or one specific room. Pick multi zone if you want to cool 2 to 5 spaces but don't want multiple outdoor condensers.
Most modern mini splits are heat pumps that do both. Cool in summer, heat in winter. Some premium models (like Mitsubishi Hyper-Heat) work down to negative 13 degrees, which is overkill for Arizona, but still good to have.
Yes. We install Mitsubishi, Daikin, LG, Fujitsu, Pioneer, MRCOOL, Gree, and other major brands. We'll recommend the right brand and model for your space and budget.
Most single zone installs take 4 to 6 hours and are completed in one day. Multi zone installs with multiple indoor heads can take 1 to 2 days.
Significantly more efficient. Modern mini splits run 18 to 30 SEER versus typical central AC at 13 to 16 SEER. Inverter compressors mean the system varies output to match demand instead of cycling on and off, which saves a lot of electricity in extreme heat.
No. That's the main advantage. They're ductless, which is perfect for spaces without existing ducts (garages, additions, casitas) or for adding zoned cooling without expensive duct work.
