What size unit do I need for a Fort Worth home?

For 1,800 to 3,500 square feet, a 22kW or 24kW air cooled unit handles the load. The biggest draw is the AC system, which on a Fort Worth August afternoon is doing serious work. Multiple HVAC zones, homes over 4,000 square feet, an elevator, or specialty equipment push you into 26kW or larger, and that’s where Cummins becomes a serious option. The free estimate includes a load calculation. We don’t guess.
