Hi my name is Jeremy, I'm here looking for some help with my Lenox G14 Gas Furnace.

I came home to a cooler house than normal today. I have my thermostat set at 62 degrees and the current temp in the house is 57.

My furnace will turn on for 30 seconds to about two minutes at a time, during this time warm air is coming from the registers. However, before reaching temp the furnace will shut off. This happens intermittently, on, off, on, off, while never reaching my thermostatically set temperature.

Gas line is on, Filter is clean as a whistle. I know little to nothing about furnaces but pretty handy all around. Could y'all help me out? Any ideas of what could be wrong? Trying to save calling a technician!
