Your furnace is responsible for keeping the home warm and comfortable throughout the cold months. However, as it ages, it can operate less efficiently and potentially require furnace repairs. Fortunately, there are a few telltale signs you can watch for to avoid getting stuck in the cold this winter, including the following.

How to Know When Your Heating System Needs Maintenance

1. Inadequate Heat

While numerous causes might explain why a furnace has stopped blowing warm air, it's almost always an indication that you need furnace repairs. In some instances, a clogged filter can hinder airflow, causing your furnace burner to shut off while the blower continues to run. Fortunately, this can be remedied by replacing the filter. Leaks in your air ducts can also result in low heat output, as the warm air escapes before it enters your home. In this case, leaks will have to be identified and sealed.

2. Short Cycling

For instance, if your thermostat is located in direct sunlight, the sensor can warm up quickly, indicating that your home has reached its desired temperature. In more severe cases, this issue may result from a damaged flame sensor or an overheating furnace due to a blockage within the ducts or vents.

3. Increased Utility Bills

Utility costs vary depending on your home's size, the age of your furnace, and how often you use it. However, if your monthly heating bills are typically predictable and you notice a dramatic increase, it may be a sign that your system needs to be repaired. As heating equipment ages, it works harder to produce heat, resulting in increased bills. If your system is relatively new, this might also be due to a damaged internal component, which can likely be repaired by a professional.
