Why does my furnace turn on and off quickly?

It could be one of a few reasons. First, you may have an electrical fault in the overheating protection system. Also, your thermostat might be damaged or malfunctioning. A number of factors might be causing your thermostat to malfunction. The wiring might be outdated and in need of replacement, the batteries could be dead or it could be the location of your thermostat.

Why is there not enough heat coming from my register?

First, check your air filter. A dirty furnace air filter can reduce airflow 60%, plus it can increase utility bills and cause costly breakdowns.

Also, a couch, bed, dresser or other big object blocking a vent prevents air from adequately flowing through your system. In many situations, this causes the heat to build up since there is nowhere for it to go. When this happens, your furnace begins to overheat and may eventually shut down.

Why is my furnace blowing cold air?

You may have an incorrect thermostat setting. Check that your thermostat fan switch is on AUTO and your furnace blower motor should start cycling on and off as temperature setting demands. Check that the HEAT setting is on, not COOL or OFF.

Your furnace may also be overheated. When your furnace overheats it goes from blowing cold air to triggering the limit switch. This switch is a safety feature designed to turn off the burners when your furnace starts to overheat. 

Your pilot light is out. If it won't light or stay lit there may be a problem with the gas supply or the thermocouple. The thermocouple is a sensor that controls the gas valve and ignition. Clean, adjust or replace it.

You may have a faulty gas valve. Or, if your system has not had annual maintenance, a valve could be stuck due to dirt, grime and debris.

You may also have a dirty gas burner. Without regular maintenance the furnace gas burner accumulates dust and other gunk that will eventually cause a fuel system failure.

It could be a faulty electronic ignition. Your system may need adjustments or replacement of failed parts. 

A weak flame sensor could also be to blame. If your furnace starts blowing warm but then turns cold, the flame sensor may need attention. A dirty or faulty flame sensor can cause the burner to keep shutting off.

Review by Cathleen G.

"Friendly, informative & helpful. With winter {furnace} cleaning they found a problem with a noisy motor. I decided to replace {the furnace} rather than wait. Very accommodating and thorough with work checking all aspects of furnace. Helpful suggestions for the air filter supply."
