Sunroom mini split installation.
Updated September 2026
Sunrooms are unique spaces that require special consideration when it comes to mini split installation. With their abundance of glass, they are prone to major solar heat gain in the summer and heat loss in the winter. This means that a properly sized heat pump is essential to maintaining a comfortable temperature. A single-zone mini split installation can be an effective solution, and at ATX Mini Split King, we offer a flat rate of $1,500 for a single zone installation, including materials and labor.
Flat pricing, same everywhere we work
| System | Flat price, installed | Included |

| Three splits | $3,500 | Everything above, three zones |
Every install is wired to code by our TDLR-licensed contractor. Long line-set runs, panel upgrades or unusual mounting can add cost, and we tell you up front, before any work starts.

Sunroom Mini Split Installation Challenges
Sunrooms are unique spaces that require special consideration when it comes to mini split installation. With their abundance of glass, they are prone to major solar heat gain in the summer and heat loss in the winter. This means that a properly sized heat pump is essential to maintaining a comfortable temperature. A single-zone mini split installation can be an effective solution, and at ATX Mini Split King, we offer a flat rate of $1,500 for a single zone installation, including materials and labor.
When installing a mini split in a sunroom, line-set length and electrical access are important factors to consider. The line set may need to be longer to accommodate the distance between the outdoor and indoor units, and electrical access may be limited due to the sunroom's design. Additionally, insulation and usage patterns must also be taken into account to ensure the mini split operates efficiently. Our TDLR-licensed contractors will assess these factors to ensure a successful installation.
Benefits of Mini Split Installation in Sunrooms
Mini splits are heat pumps, which means they can cool your sunroom during the hot Central Texas summers and handle the mild winters without the need for a separate furnace. This makes them an ideal solution for sunrooms, where the temperature can fluctuate greatly throughout the day. With a mini split, you can enjoy a comfortable temperature in your sunroom year-round, without breaking the bank. Our flat rates of $1,500, $2,500, or $3,500 for one, two, or three zones, respectively, make it an affordable option.
Most one-to-three-zone installs can be finished in a single day, and our crew will test the system before leaving to ensure it's working properly. We serve the entire Austin and Central Texas area, including Round Rock, Cedar Park, and Georgetown, among other cities. Our commitment to flat-rate pricing and honest exceptions means you'll never be surprised by hidden costs or upcharges. Contact us today to learn more about installing a mini split in your sunroom.
