The Most Common Heating And Furnace Problems

There are literally hundreds of reason why your home’s heating system or furnace may need to be repaired. However, some are more common than others. Below is a list of the five most common reasons your furnace or heating system may need to be repaired.


1. Lack of Maintenance

You invested thousands of your hard earned money in your home heating system. Proper, regular maintenance is a MUST to  keep your  heating system in proper working order. If you neglect this vital tasks you will most likely experience unexpected breakdowns, an increase in energy cost, a poorly performing unit and frustration!

2. Dirty or clogged filters

Monthly replacement of the filter  in your furnace is one of the most important things you can do to extend the life and efficiency of your furnace.

If your filter is dirty it will restrict the air flow. Your unit has to work that much harder to circulate warm air through your home. This puts unnecessary strain on your furnace and results in comfort issues.

3. Mechanical Wear and Tear

Your furnace contains many mechanical parts essential to the proper operation of your furnace. Wear and tear on any of these parts may cause issue with the performance of your unit such as belts and bearings, causing furnace overheating or poor heating control or air flow problems from fan motors.

4. Pilot or Ignition Control Problems

Along with other mechanical parts, your furnace’s ignition control could be malfunctioning causing intermittent or no heat.

In today’s modern system there is typically one of two types of ignition system in place:

  • Hot Surface Ignition or
  • Intermittent Pilot

The hot surface ignition system uses resistance heating element (somewhat like a filament in a light bulb) controlled electronically to ignite the gas burner. The intermittent pilot system is also electronically controlled but uses a high voltage electrical spark to ignite the gas pilot and then the main burners, when the thermostat calls for heat which bring us to most common problem #5

5. Thermostat Malfunctions

Your furnace’s thermostat is the device that controls and determines when heat is to be produced and how much. Problems with your thermostat can result in no heat, no fan to force the hot air through your home, or intermittent heat which result in comfort problems.

These common issues can be quickly diagnosed and the problem area identified by one of General Air’s NATE Certified technicians. Call today to have one of our professional, courteous technicians perform a Tune- Up on your Furnace or heating system. 864-299-8979
