Pdm Technician Repairing Furnace
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 The wiring might be outdated and in need of replacement, the batteries could be dead or it could be the location of your thermostat.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.

Is Your Furnace Ready for Our Winter Season?

Here are some ways to keep your home safe and comfortable this winter. 

  1. Annual heating maintenance service. This combustion and safety inspection helps your system run more efficiency and safely.
  2. Inspect your whole-house humidifier. Clean the drain line and replace the media panel, which mixes water with the flow of hot air from the furnace. Make sure the solenoid valve is working correctly and clean the humidifier's fan.
  3. Caulk cracks to prevent cold air from seeping in and weather strip windows and doors.
  4. Prevent ice dams by cleaning gutters and properly insulate your attic floor. The attic itself should be ventilated and at least 10 degrees warmer then outside temperatures. Inspect attic insulation.
  5. Prevent frozen water pipes. Insulate water piping on the outside walls. If you are worried about below zero temperatures, keep a slow stream of water running in a sink to avoid freezing and bursting water pipes. Store away the outdoor garden hose. Install an emergency pressure release valve in your plumbing system to prevent water piping from bursting. A home pressure relief valve protects life, property, and the environment. The valve is located after your main water shut off valve.
  6. Test your smoke and carbon monoxide alarm.
  7. Maintain your sump pump to avoid a messy situation.
  8. Prepare for a power outage by Building a Kit and consider a natural gas back-up generator.
  9. Clean your fireplace or stove chimney. Make sure it's in tip-top shape before the cold strikes.
  10. Check to make sure your dryer vent is not clogged and inspect your air ducts for better indoor air quality.

  • If you smell a persistent odor emanating from your air ducts.
