AQC was one of the first radon companies in the country and one of the first to guarantee the performance of its radon control systems. Since 1985, AQC has installed thousands of guaranteed radon control systems! The AQC guarantee assures you that your home's radon levels will be below the recommended level of 4 picocuries per liter for a period of five years.
Sub Slab Depressurization Systems
Below are generic drawings of sub-slab depressurization radon control systems. The drawing to the left shows the fan mounted outside, the most common approach for retrofits of existing homes. The drawing to the right shows the fan installed in the attic, the approach often used in newly constructed, “radon-ready” homes. Both types of systems work to draw or suck the radon out from below the house before it enters, and both are guaranteed to reduce radon levels to below the recommended guideline of 4 picocuries per liter.
