Common Causes of Furnace Problems

Diagnosing Your Furnace’s Problem
Is your furnace giving you trouble? The first step is to find the source of the issue. Aire Serv of Columbia, MO’s industry-leading diagnostic techniques will provide valuable insights into your furnace-related issue. Let’s narrow down the problem together. Below, you will find a few of the most common issues with furnaces.
Is Your Motor Failing?
Is your motor making strange squeaking or squealing sounds? If so, it could be an indication that your motor is experiencing excessive friction or wear, potentially leading to a failure in the near future. It’s crucial to seek immediate attention from our highly skilled HVAC service professionals who specialize in motor maintenance and repair. By addressing this issue promptly, you can prevent any further damage to your furnace and ensure its optimal performance and longevity.
Is Your Furnace Receiving Power?
If the fan isn’t responding to a temperature increase on your thermostat, there might be an issue with your power supply. This could be caused by a tripped breaker, loose wiring, or the furnace switch being turned off. However, there could be more complex problems at play, such as thermostat issues, transformer malfunctions, run capacitor trouble, control board glitches, or blower motor defects. Rest assured, our dedicated technicians can run a diagnostic test to identify the exact issue and provide the necessary solution.
Is Your Burner Staying Lit?
A burner that won’t stay lit can often be attributed to dirty flame sensors or clogged condensate drains (in the case of condensing furnaces). If your burners won’t ignite at all, it’s possible that your gas supply has been cut off. Our team can resolve these problems by cleaning key components of your system and making the necessary adjustments.
Is Your Burner Igniting?
Is your furnace emitting a rapid clicking sound yet failing to ignite? This could be a frustrating situation, but fear not! Our experienced team of technicians is here to help diagnose and resolve the issue. In such cases, a faulty control board, a blocked flue, or an improper limit control might be to blame. Our experts will thoroughly inspect your furnace and identify the root cause of the problem. You can rely on us to have the knowledge and skills to repair or replace these parts, ensuring your furnace ignites properly and keeps your home warm and cozy.
Is Your Blower Running Constantly?
Clean air filters are integral to a properly functioning furnace. First, make sure your thermostat isn’t set to “on,” as this may cause the blower motor to run continuously. If your system is set correctly to “off,” but the blower motor still runs nonstop, you may have a clogged air filter. Restricted airflow could damage the limit switch. Our skilled professionals can replace the switch and identify the root cause of the problem. If needed, we can also show you how to change your air filter.
Is Your Blower Working?
If your blower fails to turn on after the burners ignite, it could indicate problems with the motor or run capacitor. This can happen due to wear and tear over time or electrical issues. Our experienced team of technicians can quickly diagnose the issue and provide an effective solution. We will replace the faulty capacitor and troubleshoot the motor to ensure optimal performance and restore your system’s functionality. Rest assured, with our expertise, your blower will be up and running in no time!
