Home Inspection, Performance & Energy Management
AIS Houston products work with professional energy efficient engineers to create efficient designs for each individual project.   From the plans of your home, an energy analysis and an accurate heat loss calculation can be created which will enable you to see the energy savings before your home is built.   Also, the analysis and design specification will guide the mechanical contractor to properly size your heating, ventilating, and cooling systems, which will most likely save you more money.
AIS Houston Duct Leakage Testing
Is There a Thief in Your Ductwork?

There are more than a million miles of duct work in U.S. homes. And industry experts estimate that more than two-thirds of them are leaky enough to justify sealing or repair.   Leaky ducts can significantly increase air conditioning and heating bills, dramatically reduce equipment capacity and performance, as well as result in potentially dangerous indoor air quality problems.   In fact, duct leakage is responsible for many of the comfort complaints experienced by homeowners today.

Why Is Duct Leakage Important?

Leaks in forced air duct systems are now recognized as a major source of energy waste in both new and existing houses.   Studies indicate that duct leakage can account for as much as 25% of total house energy loss, and in many cases has a greater impact on energy use than air infiltration through the building shell.  Just as important, duct leakage can prevent heating and cooling systems from doing their job properly, resulting in hot or cold rooms, and humidity problems.   Worse yet, duct leaks can create air quality problems by pulling pollutants and irritants directly into the house.

Here are just a few of the problems resulting from duct leakage:
Measuring Duct Leakage

A AIS Houston duct leakage performance test involves pressurizing the duct system with a calibrated fan and simultaneously measuring the air flow through the fan and its effect on the pressure within the duct system.   The tighter the duct system, the less air you need from the fan to create a change in duct system pressure.   Testing procedures can be set up to measure only duct leaks which are connected to the outside, or to measure total duct leakage ( i.e. leaks connected to the outside and inside of the house).   Duct leakage measurements are used to diagnose and demonstrate leakage problems, estimate efficiency losses from duct leakage, and certify the quality of duct system installation.

Two different types of performance testing systems are used to measure duct leakage; a Duct Blaster® and a Blower Door.
