Installation and service of HVAC, plumbing and roofing systems throughout southern Minnesota. Over 40 technicians offer 24/7 emergency service through out our market area. Maintain offices Mankato, Minneapolis and Rochester, MN. Been a leading provider of HVAC and roofing services for over 100 years.

"The person who rated Schwickerts with a 5 star review because they make sure "the customer is satisfied" is obviously had a different experience than we did. They installed new roofs on our association townhomes and during installation, somehow dislodged several unit's furnace vents as well as someone's water heater vent. When Fall rolled around and furnaces were turned on, one customer had water dripping in her attic and down into her home. They came back several times. Couldn't find anything wrong. On third trip, the employees didn't bother looking in the attic; they simply cut holes in her ceiling and found what they said was a disconnected vent to her furnace. They told her she was lucky they found the problem, because the next step was going to be having to go up on her new roof and cut into it. Unfortunately, after they left, water continued to leak into her home. She could not allow the water to continue to damage her ceiling, so she had someone else look in the attic...and they discovered the furnace exhaust had been disconnected in more than one location, and the water heater vent had been disconnected as well. SCHWICKERT HAD THE NERVE TO SEND THIS PERSON A BILL FOR OVER $400 DOLLARS "INVESTIGATE THE CONDENSATION ISSUE" (TO CUT THE HOLES IN HER CEILING), EVEN THOUGH THE PROBLEM WAS CAUSED BY THEIR SHINGLING INSTALLATION CREW AND NOT CORRECTED. Their customer service for the issues WE HAD after installation was extremely POOR."

FAQs for radon gas testing projects in Alexandria, MN

Radon is the second leading cause of lung cancer in the U.S. The gas seeps through cracks in foundations and collects in basements and other low areas. Once you breathe it in, radioactive particles lodge in lung tissue and do long-term damage. Because you can’t see or smell radon, the EPA recommends testing your home every two years—and after major renovations—to keep your family safe.

Yes—every home should be tested. The EPA advises doing it at least every two years and any time you remodel, buy, or sell. On average, one in 15 houses nationwide sits above the recommended limit, and the only way to know where yours stands is a formal test. The equipment simply measures gas levels and won’t change your indoor environment, so the process is completely harmless.

Certified radon professionals—often home inspectors or dedicated radon mitigation contractors—handle testing. These radon testing professionals follow EPA protocols and use calibrated instruments to check levels throughout your house. Hiring a certified radon specialist means results you can trust for real estate deals, insurance requirements, and, most importantly, your family’s health.

Inspectors specialize in measuring radon gas levels, while licensed mitigation contractors design and install the systems that remove it. If your test comes back high, your inspector can point you to a qualified mitigation pro who will size and install the right fan, piping, or other equipment to bring levels down.

No—standard home air purifiers don’t touch radon. They’re built to trap dust and pollen, not radioactive gas. If testing shows high levels, you’ll need a dedicated mitigation system that vents the gas from beneath your home to the outdoors. Relying on a room purifier alone won’t keep your indoor air safe.

Opening a few windows in your home might dilute radon for a short time, but the gas seeps back in as soon as they’re closed. For a lasting fix, you’ll need a professional mitigation system—often a sub-slab depressurization fan—that pulls radon from beneath the foundation and safely vents it outside.
