When using a mini split sizing calculator for rooms below a conditioned space, apply an additional .7 factor to your final Btu outcome.
For example, if your Btu requirement via this calculator is 18,000 Btu's: 18,000 Btu's x .7 factor = 12,600 Btu's required. When in doubt, it is okay to go up a size or two.

Who installs the AC unit after I purchase it?
ACDirect does not yet provide installation services directly. However, most of our customers successfully arrange installation through local licensed HVAC contractors. These systems are designed for professional installation and typically include the components your installer will need.

Note:
Please be aware if you choose to install HVAC equipment yourself and don’t possess proper HVAC licensing, you will void the manufacturer’s factory warranty. If you are capable of a factory-compliant installation yourself, you will need a licensed HVAC contractor to sign off on your work, fully confirming factory-compliant workmanship.
