Air Conditioning: Tips To Help Extend The Lifespan Of Your In-Slab Ductwork


The state of an air conditioning system's ductwork usually determines the performance of the system. This is because if the duct system in good shape, adequate airflow to the cooling part of the air conditioner won't be a problem. This usually guarantees an efficient air conditioning process while also preventing airflow-related complications such as evaporator coil icing.

Given that in-slab duct systems are installed in the floor, the weight of the material on top of the ducts usually poses a risk to the structural integrity of the walls of the ducts. Underground installation also means that water from flooding and water pipe leaks can easily reach the ducts. All these things can lead to the premature destruction of the ducts and thus necessitating earlier-than-usual repairs. The good news is that there are ways through which you can protect your system from damage. Here are in-slab installation tips that will prolong the lifespan of your air conditioner's air ducts.

Steel reinforcements

Most ducts using in air conditioning systems cannot bear the weight of the overlying concrete alone. This is where steel structural reinforcements come in. By fortifying the area around the ducts with steel, you will be essentially shifting most of the ground weight from the ducts to the steel structures. This will help protect the duct system from the crushing weight of the concrete and will thus help to keep the walls from collapsing prematurely.

Duct sealers

When water seeps into the duct system, it accelerates the rate at which the duct walls get corroded. This then increases the chances of air duct leaks that may then reduce the performance of the air conditioning system.

It is possible to protect the interior surfaces of the air ducts from this type of damage. This can be done by coating their surfaces with a sealant. The sealant will come in between the surface of the ducts and corrosion-inducing elements such as oxygen and moisture. This will then reduce the rate of corrosion and thus prolonging the lifespan of your system. For better protection, keep away from water-based sealants.

Sloping installation

Areas with settled water usually experience accelerated rates of corrosion. These areas are also prone to encouraging mold growth. To prevent stagnant water spots from forming in your duct system, it is advisable that you create sloping trenches when installing the ducts. Doing this will eliminate stagnant water spots in the systems. It will reduce the rate at which your ducts get corroded and thus extend the lifespan of your entire in-slab air conditioner duct system.

Avoiding Air Conditioning Problems

Last summer the unthinkable happened. My air conditioner failed on a day when it was over a hundred degrees outside. I was devastated, frustrated, and most of all, sweaty. Fortunately, a kind repair technician came out and helped me to get the system fixed the same day. After things were working, I took the time to ask how to avoid air conditioning problems in the first place. The technician gave me some great tips, including avoiding blocking my air returns. I also learned how to replace my air filter, which made a huge difference. Check out this blog to learn about HVAC.
