With a chilly week ahead, many homeowners may be thinking of turning on their furnaces for the first time this season.

Marcus Mernaugh, an HVAC technician with Blue Ox Heating and Air, says he went on about a dozen service calls this weekend.

“There’s been several calls this weekend where it’s been a dirty filter that’s restricting the airflow, and that causes the furnace to want to shut down because it’s getting too hot on the inside,” Mernaugh said.
