Common Causes of Heating System Breakdowns and How to Avoid Them

While there are numerous factors that could cause your furnace or boiler to go on the fritz, understanding these can be the key to preventing the cold surprise of a malfunctioning system. If you maintain it timely and are aware of the signs that indicate your system is struggling can save you from the inconvenience and discomfort.

However, if things do go south, knowing you can rely on a reliable 24 hour heating repair service can provide significant peace of mind. In this post, take a closer look at the common causes of heating system mishaps and how you can avoid them.

Main 5 Causes of Heating System Breakdowns and How To Take Care of IT:

#1: Neglected Maintenance

The most common cause of heating system breakdowns is a lack of regular maintenance. Like any other mechanical device, heaters require routine care and check-ups to ensure proper functioning. Neglected maintenance can lead to clogged filters, dirty burners, damaged belts, and even complete system failure. Regularly scheduled tune-ups by a licensed HVAC technician can help identify potential problems and prevent them from escalating into costly breakdowns.

#2: Dirty Filters

Dirty or clogged filters are another frequent cause of heating system malfunctions. When filters become congested with dirt, dust, and debris, they restrict airflow to the unit, forcing it to work harder and putting undue strain on its components. This leads to reduced efficiency and can cause overheating, which can result in system shutdowns or even fire hazards. To avoid this, regularly replace disposable filters with clean, reusable ones.

#3: Ignition System Issues

Many heating systems rely on an electronic ignition system to start the unit. This mechanism can fail for several reasons, such as faulty wiring, dirty components, or wear and tear. When the ignition system fails, your heater won’t start, leaving you with a cold home. Regular maintenance can help prevent these issues, and if your system does use an electronic ignition, it’s important to have a professional check it periodically.

#4: Thermostat Troubles

A malfunctioning thermostat is another common cause of heating system breakdowns. If your heater is not turning on, it could be due to a faulty thermostat. The thermostat regulates the temperature and signals the heater when to turn on or off. If it’s not functioning correctly, your unit may not receive the right signals, causing it to malfunction or shut down completely. Regularly checking and calibrating your thermostat can help prevent these issues.

#5: Age and Wear

Like all mechanical devices, heating systems have a lifespan. Over time, wear and tear can take its toll on the unit, resulting in breakdowns or complete failure. The average lifespan of a furnace is around 15-20 years, but this can vary depending on usage and maintenance. If your heater is approaching this age range, consider a replacement. 

The Keynote:

In conclusion, regular maintenance, proper installation, and timely replacements are key to avoiding heating system breakdowns. By understanding the common causes behind these malfunctions, you can take preventive measures and keep your heater running smoothly throughout winter. Don’t wait until you’re left out in the cold. Schedule regular tune-ups and take care of your heating system to avoid any unexpected breakdowns.
