After a long hibernation Old Man Winter awakes in Oklahoma -- stirring leaves with freezing winds and bone chilling temperatures.
While many hide inside, Curtis McFarland with Air Comfort Solutions is out and about making sure those who want to stay warm have working heaters.
We tagged along as McFarland made his rounds, one stop was at Sheilah and Merrill Taylor's home.
"We come out and we tune it the unit up and make sure the gas pressure is fine. We check the ignition source and change your filters," said McFarland.
Since the temperature plunged, the phones at Air Comfort Solutions have been ringing off the hook.
"We went from 70 or 80 calls to 150 calls just overnight," said McFarland.
He also said not getting your heating unit checked every year could be the difference between safety and tragedy.
"It's an awful big risk to take. If it's not tuned up, if you have dirty filters, or if you can't get your ignition source right it could cause a fire."
A chance the Taylor's don't want to take.
"I have it done every year. They come in the winter and make sure I'm all set up. It's like having insurance on your car, you feel a lot safer," said Merrill Taylor.
