In nearby Lancaster, the unseasonably cold temperatures all week have kept firefighters busier than normal.
"We've had actually an increase amount of fires lately in the last week. Just small fires, and we're able to get there quick and put them out," said firefighter Christian Litz.
Many of the fires were started from things like space heaters.
"Sometimes, they don't realize where they place it. They might keep it next to a stack of clothes or a stack of books," said Litz.
What's even more dangerous than space heaters is using ovens or stovetops to heat your house. This is because of the potentially fatal risk of carbon monoxide poisoning.
"It's colorless. You can't smell it, and all of a sudden, people are getting sick, and they don't understand what's going on," said Litz.
