The furnace keeps you warm when the temperatures drop. However, even the best-serviced models get damaged with time and will need expert repairs. More importantly, looking for a professional once you notice a problem is best, as you may damage crucial components trying to resolve the issue alone. Here are some issues a furnace repair expert will help troubleshoot and solve to restore proper function.
The System Background Noises Are Different
Screeching heating systems typically have belts that are either loose or too worn to circulate air. Moreover, if you can't find any obvious issue, a loose belt could be to blame for the noise. Note that if the belt is worn out, you must purchase a new belt from a hardware store. Alternatively, ask a heating expert to replace it during the diagnostic callout.
Both the Control Unit and the Spark Plug Have Failed
If the pilot light on your older furnace keeps going out, there are several possible causes to investigate. Some possible ones might include a damaged safety switch, a clogged pilot orifice, improper flame adjustment, or a malfunctioning part. Note that if your unit has an electric ignitor, the flame sensor is crucial to ensure it is in good working order. Further, your heating system's essential safety feature turns off when it detects toxic fumes. However, the flame sensor and safety controls lose their ability to sense the fire when dirty, leading to a false alarm.
You Haven't Replaced the Filter
Changing the filter in your unit is crucial to proper function. In most cases, an overheating heat exchanger is caused by a clogged filter, which forces the furnace to shut off. As a result, you'll have a heating system that is less effective and more expensive to run. Furthermore, your system will not last long and will not provide a diminished heating output. So, if your unit is not producing enough heat or cycling on and off frequently, it is likely dealing with insufficient airflow.
The Heat Exchange System Is Damaged
If the heat exchanger is broken or fractured, toxic gas can leak out and into your home. Note that if your exchanger has a crack, you may see soot inside your heating system or a foul odor emanating from the vents. In such a case, it's crucial to call a furnace repair expert to replace the damaged component, as toxic gases can harm your health.
Speak to a competent furnace repair technician close to you when you think your system might have these issues. They will recommend the ideal ways to resolve the problem and restore efficient heating in the home.
