Zero temperature outside today and furnaces are running nonstop to maintain temperature. If your filter is dirty, your furnace may struggle to maintain temperature. Days like today are critical to be sure that your filter is clean. I’ve already had one call today where the temperature was only maintaining at 68 degrees and customer had the thermostat set at 74. I asked them about the filter and it had been awhile since they changed it. So, make sure your filters are clean for best operation in cold weather.
