As with any smoking appliance, a smoking oven is a concerning fire risk. It also negatively impacts your indoor air quality, which can put vulnerable people at risk of breathing problems. A dirty oven can catch fire if you don’t stay on top of regular maintenance, so remember to check your oven for signs that it’s time for a cleaning and remove buildup every three months to stay on the safe side.

The most common causes of kitchen fires are leaving cooking food unattended, frying food with excessive amounts of oil, and leaving flammable objects near the stovetop.

Depending on who’s doing the estimating, about 22,000 to 25,000 chimney fires happen each year in the United States. Given the fact that millions of Americans have fireplaces (and chimneys), that means chimney fires aren’t exactly common—but they’re not rare, either. Since they’re so dangerous, it’s important to take precautions to prevent them.

Regular HVAC filter changes, deep cleaning, and air quality monitoring help maintain a healthy environment.
