The duct system of a central air conditioning system is usually responsible for the delivery of warm air into the system and then dumping the cooled air into an air-conditioned space. Therefore, if the walls of air ducts collapse or if they are filled with water, the air conditioner's performance is bound to suffer. When it comes to in-slab duct systems, most duct-related air conditioning performance issues occur as a result of poor in-slab duct installation. Here are the installation mistakes that most homeowners make.
While installing the ducts deep in the ground could help spare them from damage when carrying out surface-level floor maintenance tasks, it usually increases the risks of the ducts existing under the high water table of the soils on which your home is built. This increases the chances of ground water seeping into the duct system. If this happens, your air duct system will have trouble delivering as much air as it should to the evaporator coil. Air conditioner complications such as coil frosting will start cropping up and your air conditioner's cooling ability will suffer.
Making sure that your in-slab ductwork is located above the high water table will reduce the risks of water seepage. This will then help your air conditioner to maintain its performance levels.
Forgotten vapor barriers
In-slab ducts are usually under constant threat of water infiltration. There is the threat of water leaks from burst piping systems. Ground water and rain water can also soak up the surrounding gravel fill and concrete and can therefore find a way into the duct system. If the system is left unprotected, water infiltration is inevitable. This increases the chances of mold growth, bacterial infestation, and accumulation of soil particle deposits. The presence of water and soil deposits will cause restricted airflow in the air-conditioning system. As for mold growth, it will reduce your air conditioner's ability of improving air quality since the air it delivers into your home is likely to have mold particles.
Installing vapor barriers will protect your ducts from water infiltration. Doing so will go a long way towards saving your air conditioning system from having to deal with restricted airflow problems while also protecting your loved ones from mold allergy attacks.
The walls of most air conditioner ducts are not designed to deal with the weight of thick layers concrete. Therefore, if they are left to bear the weight alone, they will collapse. This may then end up blocking the ducts and hence reducing the ability of the air duct system to move air to and from the air-conditioning system.
Reinforcing the area around the air ducts will protect the walls from the crushing weight of the overlying layers of concrete. This will ensure that your ducts keep delivering the needed amount of air to your air-conditioning system without fail.
