A furnace problem becomes an emergency when the loss of heat creates unsafe indoor conditions, exposes plumbing to freezing, or involves a possible combustion, gas, fire, or electrical hazard. Complete heat loss during freezing weather requires fast action, particularly in homes with infants, older adults, people with health concerns, or water lines located near exterior walls and unheated spaces. A furnace that still produces some heat may also require emergency service when it smells like burning, repeatedly trips a breaker, makes violent mechanical noises, or shuts down before completing a heating cycle.
Gas odors, smoke, fire outside the burner area, and carbon monoxide alarms are safety emergencies. Leave the property and contact 911 or the gas utility first. Lancaster Brothers can inspect and repair the furnace after the building has been cleared for reentry.
