Gas Furnace Problems

As soon as the cold weather arrives, many people call Deljo Heating & Cooling for furnace repair in the Chicago Loop and other areas of Chicagoland. Whether it’s a residence or a commercial setting, the basic causes of gas furnace problems tend to be similar, and by knowing what these are you can become proactive and prevent many of them from occurring.

Lack of Maintenance

Regular, professional maintenance is absolutely essential to keep your system working properly. Lack of professional maintenance can lead to a poorly performing unit, unexpected breakdowns and increased energy costs.

Dirty or Clogged Filters

Monthly replacement of the filter in your furnace is one of the easiest and most important things you can do to increase the efficiency and extend the life of your furnace. A dirty filter restricts the air flow through the system and makes your furnace work harder to circulate warm air.

Mechanical Wear and Tear

Your furnace contains many mechanical parts essential to the operation of the system. Wear and tear on these parts can lead to numerous problems, but a heating specialist performing regular maintenance can prevent many of these problems from occurring.

Pilot or Ignition Control Problems

Today’s gas furnaces typically contain one of two possible ignition systems:

  • Hot surface ignition
  • Intermittent pilot

The hot surface system uses an electrically controlled resistance heating element (like the filament in a light bulb) to ignite the gas burner. The intermittent pilot system is also electronically controlled but uses a high voltage electrical spark to ignite the pilot and main burner. If the pilot isn’t working, check to see if an electrical surge has tripped a breaker cutting off power to the unit. If not, unless you’re highly skilled, it’s probably best to call for professional help.

Thermostat Malfunctions

The thermostat determines when and how much heat is produced to keep you warm, and problems with the thermostat can lead to intermittent heat or no heat at all.

It’s essential to remember that furnaces and thermostats are not mix and match. Using the wrong thermostat with a furnace can cause serious problems, so with this problem it’s best to call in the professionals at Deljo.
