The middle of a Wisconsin winter is no time to discover your furnace is malfunctioning. Not only is it uncomfortable, but it is dangerous as well. Below are a few signs that you need a repair service to keep the heater running for the rest of the season.

Furnace Repair Warning Signs 

1. Unusual Noises

All furnaces will make noise, but new, loud, or unusual sounds are an indication that something is wrong. As a heating system nears the end of its life span, it can start making moaning or clanking noises, especially when cycling on or off. This could be due to a loose or broken part in the system being forced against metal when it turns on.

2. Bad Smell

You may notice a dusty smell when firing up the furnace for the first time of the season, but it should dissipate quickly. However, a burning smell may indicate that the unit is overheating or that there are potentially dangerous electrical issues. A moldy or musty smell may indicate mold growth in the ducts. A repair service should address any odor that doesn’t go away.

3. Uneven Temperature

Extreme cold weather makes it more challenging to heat the home evenly. However, if you notice irregular temperatures throughout the house even in milder weather, there are likely issues in the ductwork, thermostat, or blower within the heater. Likewise, if you constantly have to raise the thermostat to keep the house warm, this can indicate the need for a repair call.

4. Decreased Air Quality

The HVAC system helps keep indoor air quality high through filters, and some heaters also have air purifiers. If there is more dust in the air or it seems hazy, you should replace the filter. An increase in allergy symptoms such as runny nose and eyes, sneezing, or coughing are also signs that indoor air quality has dropped.

5. Discolored Pilot Light

Gas furnaces have a pilot light that enables the igniters to work and heat the air. The pilot light should be blue; if it is red, green, yellow, or orange, there are too many condensed substances, such as rust or tar, within the components. Condensates decrease the efficiency of the heater and also emit harmful gases.
