The middle of a harsh Ohio winter is no time for your furnace to blow cold. You want to curl up in a cozy house after you deal with harsh weather conditions, so it’s time to take a look at the reasons the furnace may be blowing cold. Some issues with the heat are easy to fix, but others require a qualified professional to get you away from the space heater and back to a house that’s warm all over. 

• Thermostat problems – Your heat-related issue may simply be a thermostat that isn’t set correctly. Check that the thermostat is on and set to the heat setting. Then ensure that the thermostat temperature is higher than the ambient air temperature. If you use a smart thermostat or a programmable thermostat, check the programming to see if the temperature is set too low. If your thermostat doesn’t turn on or respond to temperature selection, it may be the problem.
• Electrical problems – Many systems need electricity to power the blowers or light the pilot light. Check the breaker box and make sure breakers haven’t tripped or fuses haven’t burned out, as that would prevent it from working properly.
• Ignition problems – Your HVAC system may not be generating heat because it can’t ignite properly. It may be in a lockout mode that prevents it from turning on, which needs to be reset by turning it off and on. It’s possible the pilot light was blown out and needs to be relit before the furnace kicks on.
