When you’ve gone to the expense of putting in a high-quality, energy-efficient heating, ventilation and air conditioning (HVAC) system, you don’t want to affect its efficiency or shorten the life of the system with a mediocre support structure. Ducts distribute conditioned air throughout a building. Poorly insulated, poorly connected or leaking HVAC ductwork can result in loss of 20 to 30 percent of conditioned air, costing hundreds of dollars a year in heating and cooling costs, creating an uncomfortable and potentially unhealthy living space and overworking the system by up to 50 percent.Indoor Air Quality requires proper ductwork maintenance.

Air Ducts and Energy Loss

According to the Department of Energy, properly constructed and maintained air ducts are vital to achieving energy efficiency in an HVAC system. Pressurized air must flow through ducts and over the coils, with air flowing freely through both the supply and return registers. Leaks or improper joins affect the pressure in the system, resulting in loss of conditioned air and entry of unconditioned air. This loss of conditioned air means that the HVAC system must work harder to reach and maintain desirable temperatures and consume more energy to do so.

Air Ducts and Indoor Air Quality

A poorly designed or maintained air duct system affects indoor air quality in several ways. Leaks allow particulates to enter and circulate through the system. Animal dander, insect parts, mold, bacteria, dust and gasses like radon or fumes from chemicals are a few of the pollutants that can enter a leaking system. Many of these substances are allergy and asthma triggers that create an unhealthy environment for those who suffer from these maladies.

In Houston, high humidity is a problem during much of the year. Leaking ducts allow moisture into the system, creating an uncomfortable indoor environment. The air conditioner must work harder and use more energy to remove moisture. Excess moisture also creates an environment for mold, mildew and bacteria growth. Unchecked, these organisms can cause wood rot and create wet spots and mildew growth on walls, floors and textiles. They can also affect the health of those living in the building.
