You probably haven't used it yet, but with colder weather just around the corner many of you will be firing up your furnace or space heaters for the first time in months.
But flipping that switch could be more dangerous than you might think.
It's normal this time of year in texas to suddenly have to switch from AC to heat.
But if you haven't had your heater checked out in a while you could be putting your house and yourself in danger.
Firefighters say a house fire in Belton started when the owner turned on the heater for the first time in months.
Fred Newbury has been an H-VAC technician for more than 45 years, he says there are a lot of things that can go wrong on a furnace and fire danger isn't the only thing to worry about.
"The worst thing especially with older units is cracks that create carbon monoxide leaks. Basically it's the kind of problem you go to sleep and don't wake up," Newbury says.
Fred and firefighters say heaters should be checked out at least once a year.
Experts say keeping your heater maintained will not only keep you safe... it will save you money.
Proper maintenance will give you better utility bill, you'll end up saving back the money and have safety.
And when that cold front hits you won't have to second guess keeping warm.
