Zoning & Ductwork
Kyle & San Marcos Air Conditioning

Duct systems distribute conditioned air.

Residential duct systems leak 20% or more of conditioned air according to some national studies.  This means that 20% of cooling capacity, heating capacity, and utility dollars are going into unconditioned space due to air loss alone.  Poorly insulated ducts also cause the air inside the ducts to heat up in summer and cool off in winter before the air reaches the living space inside the home increasing utility costs.  Duct leaks also cause pressure imbalances inside the home causing indoor air quality problems.

Common Duct Problems and Solutions

Common Duct Problems: Poor Insulation & Leaks

Poorly insulated points or sections of ducting can cause moisture and microbial growth to occur. Air is then circulated past the molds growing in the duct system, distributing mold spores thru out your home. Since these spores are created after the filter; even the best filtration system can’t fix this kind of indoor air quality problem. In order to achieve better indoor air quality (IAQ), the duct system is the problem and you must find air conditioning repair in San Marcos.

Dust streaks around supply vents are often thought to be caused by a dirty duct system. Most of the time dust streaks around supply vents are caused by leaks in the duct system between the “bucket”, the sheet rock, and the supply vent cover. A venture effect caused by the moving air sucks dirt, humidity and heat directly from the attic. This type of problem is the result of poor duct construction or a duct system that is coming apart.

Common Duct Problems: Poor Design & Installation

We find many duct systems to be poorly designed and installed. A sure sign of duct a design problems is rooms that heat or cool unevenly. Other duct design problems that result in lower equipment efficiency and poor indoor air quality are not so obvious.

Proper duct design is also important in achieving and maintaining proper system operation and efficiency. Many homes have supply air outlets placed near the interior walls of the home. This poor duct installation practice creates a need to run high duct static pressures in order to push air all the way from the interior wall to the exterior wall where the majority of the heat enters your home. This one poor duct design feature creates noise at the vents, excessive static pressure inside the duct, and a host of potential problems.

Will Zoning solve my problem?

Uneven heating and cooling between floors or even sections of a ranch style home in Central Texas can often be resolved by installing a zone system.  Zoning is term used to describe dividing a home into different areas for the purposes of heating and cooling.  The temperature in each area can be controlled separately using a combination of dampers, air bypass devices and electronic controllers.

Not every home is a good candidate for zoning.  Poorly installed zoning systems can destroy system efficiency, increase system repair costs, and cause early system failure. Setting up a good zone system is complicated but our AirOne technicians can get the job done right to make you comfortable and protect your air conditioning and heating investment.
