West Line Historic District Home

An image of Andrew McCalla's Civil War-era home.
Because the house is historic, we specifically chose concealed attic units, and ones that could be driven by outdoor units that could be placed some distance away from the house. As for system performance, we’re comfortable.

Andrew McCalla’s Ausitn, Texas, home dates back to the Civil War era. Its 20-inch-thick walls presented a problem during a remodel/renovation, but an S-Series Variable Refrigerant Flow zoning system from Mitsubishi Electric was up to the challenge. The result: reliable operation in Austin’s high heat and humidity, and a clean look that keeps all eyes on the historic home. Download the PDF below to read more. You’ll hear from the owner, general contractor, HVAC contractor and building science consultant, and see a photo of the home.
