Quality Starts Here

Appearing monthly in Professional Builder's new "Quality Matters" column, IBACOS authors an article that offers expert construction detail and illustrations on a specific topic. Topics range from foundations, framing, thermal enclosures, mechanical systems, and exterior and interior finishes, and focus on high-impact details that inform readers about the best method for achieving high performance in that context, and ultimately, lead to better-built and durable homes.

But just because the calculated load is 4 tons doesn’t necessarily mean you want a 4-ton air conditioner.
