Those who specialize in repairing heating units are working around the clock these days.
As the temperature dips, business picks up at places like Fayette Heating and Air in Lexington.
Owner Bret Melrose says the company's call center has been flooded with calls all weekend.
Melrose says the main reason why heating units fail is due to a lack of attention. He advises homeowners to have their heating and air units serviced in the spring and fall to prevent malfunctions in the cold and hot months. Additionally, Melrose says changing the filter frequently can keep your furnace running more efficiently.
