Q: How do you remove radon from your home?

• <div><p>You can vent radon out of your house sometimes by simply opening a window, but it won&rsquo;t remove the source, and will likely rise above recommended levels quickly. A professional will be needed to assess your home, and determine the best strategy for radon removal. Active radon sump pumps and soil depressurization systems are often used to forcefully vent the radon from your home.</p></div>

Q: How long does the radon abatement process usually take?

• <div><p>Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.</p></div>

Q: How does radon enter my home?

• <div><p>Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.</p></div>

Q: How long can you go without a radon fan?

• <div><p>Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.</p></div>

Q: Do radon mitigation systems come with warranties?

• <div><p>Yes, many systems include warranties for performance. Confirm terms with your installer.</p></div>

Team started to cutopen HVAC duct and later figured out the machine is not working , followed different approach to clean each vent. I contacted sales person and he said it is going to be same results either way and same price was charged. Charged 1.7k for 3400 sq ft home for duct cleaning."
