If your furnace is blowing cold air, try a few easy fixes yourself before calling a technician. You might save some money!
What setting is your thermostat on?
If the thermostat is set to “ON,” this means the system’s blower is going to stay on 24/7, even if the air isn’t heating. Switch the setting to “AUTO,” then make sure your thermostat is set higher than the indoor temperature. This should make your furnace kick in.
Some homes have battery-operated thermostats. Even if the thermostat hasn’t run out of power, sometimes faltering batteries can send misreads to the furnace unit. Try replacing the batteries to see if this makes a difference.
Your furnace is blowing cold air now, but an hour ago it was blowing hot! What happened?
A common problem is an overheated furnace. If your furnace’s air filters are dirty, they could block proper airflow and the furnace will have to work overtime to heat the home.
Try changing the filters and turning the unit off and on again to see if it fixes the problem.
If your gas furnace is blowing cold air, your pilot light could be out. If you feel comfortable doing so, simply try to re-light it.
If the pilot won’t light, try cleaning it and ensuring that the gas is turned on. Maybe it lights, but goes out again right away. If so, that means you’ll need a new thermocouple, and that’s an issue Roberts Mechanical can fix quickly.
