FOLEY -- A Foley plumbing, heating and air conditioning company is trying to protect households by offering free Carbon Monoxide check-ups in homes around the area.

Carbon monoxide is a very serious hazard that is nicknamed "the silent killer" because it is invisible, odorless, and tasteless.

It is especially threatening during the winter months, as the cold temperatures may freeze or damage ventilation.

"Any flame-burning appliance can create carbon monoxide...and if it gets to dangerous levels, it could be lethal," says David Juilfs, of Neighborhood Plumbing, Heating and Air Conditioning.

Juilfs says they are hoping to prevent future fatalities after two Lindstrom women died of carbon monoxide poisoning earlier this week.

"If anybody has any concern at all about their furnace malfunctioning and possibly leaking [carbon monoxide] into their home," Juilfs says. "If they give us a call, we'll come out and check their CO levels for free."

And if they find anything, Juilfs says it's a fairly inexpensive fix.

"Forty-nine dollars is a small price to pay for your life."

Annual tests for carbon monoxide levels are relatively quick processes (30-90 minutes), and Juilfs says homeowners with flame-burning appliances should have detectors installed.

Neighborhood Plumbing, Heating and Air Conditioning serves homes in St. Cloud and the surrounding area.  To schedule your free check-up, call 320-251-7872 or visit their website.
