Columbus experiences an average of 42 freeze-thaw cycles each winter. Outdoor temperatures swing from 20 degrees at night to 45 degrees by afternoon, then drop again after sunset. These rapid temperature changes create condensation inside furnace cabinets and flue pipes. Moisture corrodes thermocouples and oxidizes flame sensors faster than in consistently cold climates. Columbus homeowners replace thermocouples 40 percent more frequently than residents in northern states where temperatures stay below freezing for weeks at a time. The pilot light won't stay lit because humidity degrades the components that sense flame presence and regulate gas flow.
Grand HVAC Columbus technicians understand how local conditions affect furnace performance. We account for basement humidity levels common in Central Ohio homes and check for moisture infiltration during every diagnostic call. Our service history in neighborhoods like German Village, Clintonville, and Bexley gives us insight into how older home construction affects furnace installations. We know which brands hold up better in damp basements and which thermocouple styles resist corrosion longer. That local knowledge means faster diagnosis and repairs that address the environmental factors specific to Columbus homes.
