TULSA - Air-condition and furnace repairmen tell 2NEWS with the dropping temperatures, they are receiving hundreds of calls.
They say it is important for homeowners to have their furnaces checked. Technicians are able to find cracks and other damage which could lead to carbon monoxide leaks and even fires.
"We're looking for cracks in the metal. Cracks in the heat exchanger that would allow gasses to escape in to the house," said Mike Rampey with Air Assurance.
Homeowners say, they want to make sure their heating units are working properly to avoid furnace-related fires.
"You know, [we want to] make sure that everything is ready to go for when we do flip over to the heat," said homeowner Sandy Morgan.
"You have a pretty phenomenal investment in your heating and air conditioning system," Morgan said. "You want to keep it in good working order so that you're not having to pay thousands of dollars to replace it before it does need to be replaced."
