Common Furnace Problems All Homeowners Encounter

You may rarely experience something as terrible as a broken or malfunctioning furnace. Everything in your home is fine and dandy as long as your furnace is working the way it should. In fact, you may not even notice the HVAC system until something goes awry.

We all face a type of maintenance problem with our heating systems at some point. Fortunately, most of these issues are easy fixes that you can troubleshoot yourself or trust an HVAC contractor in Battle Ground, WA, to get things in order. Understanding the most common furnace problems is the first step to help you identify issues early and fix them.

Common Furnace Issues

Here are the most common furnace problems you need to look out for:

1. The Pilot Light is Out or Cracked

One of the issues you can spot easily is a faulty pilot light. It may have gone out due to a strong draft, a faulty thermocouple, or a dirty burner orifice. A yellow pilot light is also concerning as it may indicate high carbon monoxide levels. If this happens, we recommend calling an expert immediately.

2. Faulty Thermostat

Although often overlooked, a broken thermostat is one of the most common furnace problems. Check to make sure the furnace fan is not running constantly, as this overworks your thermostat battery and causes furnace inefficiency.

3. Clogged Filters

Air filters are an essential part of the furnace, and if they get too dirty and clogged, they can lead to substantially reduced airflow. Additionally, clogged filters can also damage the limit switch. Make sure to change the filters every few months for optimum heating.

4. A Noisy Furnace

If you hear any loud banging, squealing, or just rattling, there’s a budding problem in your furnace. It may be due to loose components that need tightening, a rusty blower motor, or old ducts. We recommend contacting a professional like Advantage to help you save money in the long run.

5. Over-Cycling

Have you noticed that your furnace keeps cycling on and off, although it’s not wintering? If yes, then your furnace may have a clogged filter, irregular airflow, or you are running your furnace at extreme temperatures. You may want to get this fixed immediately, as frequent cycling can lead to higher energy bills.

6. The Furnace is not Producing Heat

It may sound alarming, but do not worry. Your furnace not producing heat may not indicate a concerning issue. Some of the reasons your heating system is not heating your home may be:

  • The thermostat fan setting is on.
  • The temperature on the thermostat is set too low.
  • The air filters are clogged
  • There is no flame to ignite the fuel and warm the air–faulty pilot light.

These are only a few of the many furnace problems you might face.

Although you may be capable of troubleshooting most furnace issues by checking the thermostat and circuit breaker, there are times you will need help from a trained HVAC technician. At Advantage Heating and Cooling, we cater to all your heating needs with quality furnace repair in Battle Ground, WA, and more.
