Cooling a Home Office or Converted Room with a Ductless Mini Split
Updated September 2026
If you have a home office or converted room that needs cooling, a ductless mini split is a great option. These systems are heat pumps, which means they can cool your space through the hot Central Texas summers and handle the mild winters without a furnace. At Old West Minisplits, we offer flat-price installations, so you know exactly what you will pay upfront.
Our installations include equipment, labor, line set, standard electrical, refrigerant, testing, cleanup, and even a trip to Home Depot for touch-up paint. We also disclose any potential exceptions to our flat pricing upfront, such as a very long line set or a panel upgrade that your house already needs. This way, you can plan and budget with confidence.
How Ductless Mini Splits Compare to Other Options
Ductless mini splits are a popular choice for cooling a single room or zone because they are efficient, quiet, and do not require ductwork. Unlike window units or portable ACs, which can be loud, block a window, and drip condensate, ductless mini splits are a more permanent and efficient solution. They also do not have the high upfront costs of a traditional HVAC system.
Why Choose Old West Minisplits for Your Ductless Mini Split Installation
At Old West Minisplits, we offer flat-price installations that are competitive with quote-based contractors. Our prices are $2,000 for a 1-zone installation, $3,700 for a 2-zone installation, and $5,400 for a 3-zone installation. We serve the Austin area and the I-35 corridor, from Waco/Killeen to San Antonio, with the same flat pricing throughout our service area.
Troubleshooting and Maintenance
If you have an existing ductless mini split that is not cooling properly, it may be worth troubleshooting the issue before calling for repair. Check your filters, ensure that the unit is properly sized for your space, and verify that the remote control is working correctly. If your system is old or was not installed correctly, it may be more cost-effective to replace it with a new one rather than pursuing repairs.
