Top Reasons For Furnace Repair

Many homeowners wait until their furnace stops working to contact a technician. It is essential to know when to repair your furnace to avoid having to replace it or paying a high cost of severe issues. Here are some top reasons for furnace failure and why you should repair them immediately. 

Furnace Doesn't Turn on Automatically

When your furnace is working properly, it should switch on automatically when it receives a signal from the thermostat. However, if you realize it isn't turning on automatically and it is getting cold in your home, you should consider calling an HVAC technician. 

One of the reasons is that the circuit breaker is turned off. You can fix this by flipping a switch at the breaker box. Sometimes the issue is caused by a low temperature on your thermostat. In this case, you might need to adjust the thermostat settings. But, if all these troubleshooting attempts don't resolve the problem, it means your furnace needs to be repaired by a professional.

The Thermostat Isn't Working

Another reason you will have to repair your furnace is because of a faulty thermostat. One sign of a malfunctioning thermostat is a fan that runs constantly. As a result, your thermostat battery will run out and cause the furnace to be inefficient. If this problem is consistent with different heating settings, you need to call an HVAC technician to resolve the issue.

The Furnace Has Dirty Air Filters

Your furnace will not work efficiently with dirty air filters. In this case, it works harder to minimize the reduced airflow. As a result, you will have increased energy consumption and higher power expenses. Additionally, dirty filters can ruin your furnace's limit switch. Also, clogged or dirty air filters cause your furnace to go on and off constantly.

An Air Leakage in Your Furnace

If you have checked the ducts and switches and the furnace is running, but your home is still chilly, there may be an air leak in your system. This means warm air is moving out instead of heating your home. Another possibility is that there is a draft that is allowing too much cold air in your home. In any of these cases, call a technician to identify the source of the leak and make the necessary repairs.

Your Furnace Is Noisy

It is normal for your furnace to make noise as it operates. You will hear clicks when the thermostat attains a specific temperature. Also, the furnace will be noisy when air is moving through your ductwork.

However, some noises mean there is a problem, so your system should be inspected and repaired. For example, a knocking or rattling noise means something in your furnace is loose and should be adjusted or tightened. A rumbling noise means there is fuel residue in the combustion chamber after turning off the system.
