Keeping It Up and Running: 4 Most Common Central Heating Problems to Watch For

Do you have central heating problems?

Did you know that the heating of your home typically makes up 42% of your utility bill? Did you also know that with the proper equipment, insulation, and seals you can save about 30% on your utility bill? If you have central heating, the first step is to update and maintain your equipment.

That’s what today’s lesson is all about. We’ll walk you through the four most common central-heating issues. You’ll be able to diagnose your problem, and get your system and running properly.

Read on to discover more.

Pilot Light or Ignition Control Malfunction

In today’s world, heating systems typically have two types of ignition systems. The first is called a “hot surface ignition.” It uses electricity to heat a silicon carbide (or silicon nitride) ignitor to red-hot temperatures. They need replacement regularly.

The second is an “intermittent pilot.” It uses electricity to warm a heating element or emit a spark to light the gas.

First, check to see if your system has a pilot light. Then check to see if it’s lit. If not, or if it’s only lit intermittently, your problem may stem from a pilot light or ignition control malfunction.

Dirty or Clogged Filters

When your filters are clogged or just plain dirty, the airflow to your system is reduced. That means that your appliance must work harder to circulate air.

This can mean a higher energy bill. It can also mean that you have to crank your system up even higher to get your house warm.

Dirty filters can also blow your limit switch. It controls your system’s fan. Fortunately, it’s an easy problem to fix. To lower your winter power bills, simply change your air filter once a month.

If you live in a house with excessive smoke, pet dander, or aerosols, it’s even more important. Allergens and pathogens are caught by your filter. If it’s dirty, those allergens and pathogens recirculate throughout your house.

Lack of Airflow

This is a little more difficult to diagnose because it may be caused by a whole slew of factors:

  • Leaky ductwork
  • Faulty fans
  • Broken motors
  • Torn belts
  • Ruined bearings

These sorts of problems are common in poorly maintained, older heating systems. Not only will your house remain cold, but your system will overheat. That may cause further damage to your system.

9.6% of residential fires are caused by heating problems, so take precautions. Listen for squeaking sounds or others that may indicate a broken part attached to the motor. If you can’t find any, walk alongside the ductwork in your attic.

Feel for any air blowing on you. If you find some, you’ll notice that the seal on that portion of the duct will have a hole. You can reseal it yourself with proper duct tape.

Faulty Thermostat

Thermostats glitch every once in a while. It doesn’t matter whether you have a traditional thermostat or a new, fancy smart thermostat. Here are some of the main causes:

  • Low battery
  • No battery
  • Misread temperatures
  • Misused settings

Be sure to check these first. If your thermostat is older, it may also need a complete replacement.
