Common Causes of AC Fires & How to Prevent Them

Air conditioning is essential equipment when it comes to keeping your home cool during the hot summer months. However, it’s necessary to be aware of the potential dangers of having an air conditioner unit in your home, namely the risk of fires.

At Woods Family Heating and Air, we understand the importance of staying calm while maintaining safety. That’s why we’ve compiled a list of common causes of AC fires and how to prevent them. By following these tips, you can ensure that your air conditioning unit runs smoothly and doesn’t threaten your home air conditioning  in Roanoke, VA.

Common Causes of AC Fires

  • Clogged Air Filters


Dirty air filters are one of the most common causes of AC fires. Air filters are designed to trap dirt, dust, and other debris from entering the air conditioning system, which can cause damage to the unit or reduce its efficiency. However, if the air filter becomes clogged or dirty, it can restrict airflow, causing the air conditioner to work harder than it needs to. This can lead to overheating, which can result in an AC fire.

  • Faulty Wiring

Faulty wiring is another common cause of air conditioner fires. If the electrical wiring in your AC system is frayed, corrupted, or damaged, it can cause a short circuit or spark that can ignite a fire. This is particularly dangerous in older homes or buildings with outdated electrical systems.

  • Overworked AC Systems

During the hot summer, your AC system works hard to keep you cool and comfortable. However, if the air conditioner is overworked and needs to be maintained correctly, it can overheat and catch fire. Overworked air conditioner systems are hazardous in commercial buildings or homes with multiple AC units.

  • Blocked AC Vents

Blocked AC vents can cause restricted airflow, which can cause the air conditioning system to work harder than it needs to. This can lead to overheating and, ultimately, an AC fire. Blocked AC vents are particularly common in homes with pets or excessive dust.

Preventive Measures

  • Change Your Air Filters Regularly

The easiest way to prevent AC fires caused by dirty or clogged air filters is to change them regularly. We recommend changing your air filters at least once every three months or more frequently if you have pets or allergies. Changing your air filters ensures that your air conditioning system runs efficiently and reduces the fire risk.

  •  Schedule Regular Maintenance

Regular AC maintenance is essential to keep your system running efficiently and effectively. During a maintenance visit, a technician will inspect your AC system, clean the coils and air filters, and check for potential issues. In addition, regular AC maintenance can help prevent AC fires caused by overworked AC systems or blocked AC vents

  • Hire a Licensed Electrician

If you suspect that your AC system’s electrical wiring is outdated or damaged, we recommend hiring a licensed electrician to inspect your electrical system. A licensed electrician can help ensure that your electrical system is up to code and replace any faulty wiring that may be a fire hazard.

  • Keep Your AC Vents Clear

To prevent fires caused by blocked vents, you must keep them clear of debris or obstructions. Regularly clean your air conditioner vents to ensure they’re free of dust, dirt, and pet hair. Also, ensure that furniture or other items aren’t blocking your AC vents.

  • Upgrade Your AC System

If you have an outdated air conditioning system or an overworked one, consider upgrading to a more energy-efficient model. Energy-efficient AC systems are designed to reduce energy consumption and help prevent fires caused by overworked AC systems.
