Furnace repair in Maryland's winter conditions
With IECC climate zone 5 winters across much of Maryland, furnaces run hard from November through March. Problems that went unnoticed in fall, like a weak flame sensor or a clogged filter, usually show up during the first real cold front.
Natural gas furnaces are common in Maryland. Most no-heat calls on gas units trace back to the ignition sequence: inducer, pressure switch, ignitor, flame sensor. A technician checks each step in order.
Many Maryland homes still burn heating oil. Oil furnaces need an annual nozzle and filter change; a clogged nozzle or a tripped primary control (the red reset button) is a frequent winter failure. Don't press the reset more than once.
