Context can help professionals direct their attention to where duct leakage can best be addressed.

This time, the conversation turns to duct sealing and what it means in terms of system efficiency and energy savings.

The ICC passed a proposal that will require more duct testing in an effort to combat duct leakage, conserve energy, and reduce utility bills.

Let’s look at five hidden reasons HVAC systems might not keep up when the temperatures get hot, how to test for them, and potential repairs.

The Charlotte Mecklenburg School System (CMSS), the 19th largest in the U.S. with a $1.3 billion operating budget, recently decided to take action to identify school system buildings that might be exhibiting air leakage.

As common as the duct leakage problem is, it’s also very easy to go in with less-than-adequate knowledge for solving the problem in customers’ homes due to all the possible variables in play.

Even though the overwhelming evidence points to duct leakage as a main culprit behind a slew of building performance problems, little attention has been paid to addressing the situation … until now.

For those interested in energy-efficient buildings, chilled beam technology is rapidly gaining the attention here in the U.S. that it has long enjoyed elsewhere around the globe.

The National Comfort Institute Inc.’s (NCI) mission is to help its members implement HVAC and home-performance contracting through easy-to-use strategies. That mission was accomplished at its recent annual summit, where the focus was on the best practices involved with selling and installing air upgrades.

Instead of focusing on the poor work our industry has been plagued with, we decided to dream about how an ideal duct system could be built.
