Most radon fans come with a 5-year warranty directly from the manufacturer but have a life expectancy of 10-15 years. A fan that is in good working condition will have a constant low humming, similar to a refrigerator. If the motor starts to make a screeching or whining noise, or if it has stopped humming all together then the fan needs to be replaced. There isn’t a way to repair the motor since they will only run for so long then burn out. All fan replacements come with a brand new 5-year warranty directly from Radon Away.
We offer full inspections on sub-slab radon mitigation systems, crawl depressurization systems, humidistat sub-floor fan systems, passive to active, or sump pump/perimeter drain mitigation systems. Our certified technicians will do a full system inspection to verify everything is to guidelines and current codes. We can provide a written outline if required for a real estate transaction and for homeowner property records.
A sump pump is a small pump installed in the lowest portion of a basement or crawlspace. Its purpose is to help keep the area under the property dry and to prevent it from flooding. Water flows into the sump pit through drains or by natural water migration through the soil. Similar to radon mitigation fans, sump pumps have an average life expectancy of around 10 years, however, if your sump pump is running frequently due to high water levels it may need to be replaced more often. American Radon LLC offers full sump pump installations and sump pump replacements.
As certified and licensed radon mitigators, we must follow the current AARST/NEHA regulations and guidelines for all radon mitigation systems. However, over the years these codes have changed and been updated, especially when it comes to pipe and exhaust regulations. If you have an older system that does not have the exhaust piping going all the way to the roofline contact us for a full system inspection and pipe extension to bring your system up to code. We charge a flat service call fee, then bill in 15-minute increments to help you save time and money.
A subfloor or structural floor dehumidification system is commonly found in homes that either has a floating wood subfloor or a floating concrete subfloor in the basement. Essentially, the house has a giant crawlspace underneath the entire footprint. It is common in this area for builders to have installed a moisture control system. These usually consist of either one or two intake vents that bring fresh air into the crawlspace. On the opposite side of the basement, you will find a 6-inch inline duct fan with an exhaust going to the outside. These fans have a control switch humidistat that regulates when they turn off and on. These can be set from 0 to 70% humidity, however, here in Colorado we usually set them around 25% or 30%. This means that if/when the moisture in the crawlspace gets above 25% or 30% the in-line fan activates and pulls air in through the intake vents. This reduces the relative humidity in the space to get back to the desired percentage, and it also evacuates any soil gases that may be trapped in the crawlspace. Even though these systems often can be used to control high radon levels they have a very different set of guidelines than a radon mitigation system. Some homes that have borderline results can achieve the 4.0 pci/l or below mark by adjusting the humidistat on their dehumidification system. When the dehumidification system activates it expels radon gas and it brings in fresh air from the other side which helps to dilute the radon gas. The benefit to these systems is that it’s already in place in the home and a fan replacement or humidistat replacement is very inexpensive compared to a full crawl space radon mitigation system. In addition, the systems are vented at ground level and there’s no need for 4-inch piping running up the house and venting above roof line so they can also be a bit more aesthetically pleasing for the homeowner.
