With temperatures cooling down, many people are turning up the heat. There are some safety measures you need to consider when firing up your furnace for the first time.
When you first turn on the heat, you could be risking your safety if you don't first check your furnace.
"Some of the insulation, tape given way could be a fire hazard," said William Barlow with Abner's Heating and Air.
Service technicians with Abner's Heating and Air are checking Sherwin Rader's heater.
"Sounded like I had some build-up in the chimney, so I'm glad I called him," Rader said.
They're checking the furnace's pilot light for color.
"Make sure it's a nice blue flame. If you have a yellow flame, or soot, you have a problem," Barlow said.
But Barlow says the biggest potential problem is a silent danger.
"You can't smell carbon monoxide, but it is deadly," he said.
The U.S. Environmental Protection Agency warns as you turn up the heat, the risk for carbon monoxide poisoning goes up. They recommend you get a detector. It's about 20 dollars at your local store and works like a smoke detector.
Experts say the best advice is to have your furnace checked once a year by a qualified service technician.
