3 Furnace Problems That Could Affect You This Winter

Cold Air From Vents

Several problems that could cause cold air to come from vents when you’re using your heater. If you have an old gas furnace, check if the pilot light is on. If the light is out, it can’t fire up the burners to produce heat. If you don’t feel comfortable handling the pilot light, our service technicians will gladly help and show you the process.

Additionally, dirty or clogged air filters can restrict warm air coming into your home. Clean or change your air filters regularly. A clean filter helps to keep your furnace running efficiently.

The Blower Fan Does Not Shut Off

If the fan won’t shut off, there could be a problem with the limit switch. The switch determines when the furnace’s blower fan turns on and off. Its safety feature will turn off the burner or furnace if the temperature gets too high.

Operating the furnace when there’s a problem with any component wastes energy and can damage the unit. Our service technicians will check all components to determine the source of the problem.

The Furnace Won’t Turn On

If the screen is blank, check that the batteries are functioning. If the thermostat is working fine, make sure that it is set to “heat.” Check the circuit breaker if you have an electric heater. Make sure the pilot light is on if you’re using an older gas furnace.

A clogged filter can also limit airflow and cause heat pressure to build up in the furnace. Safety features in many of today’s designs will prevent the system from cycling on so you avoid further problems. If you need a furnace repair or new furnace installation, call Cool Connections, Inc.
