Winter is the time of year when you rely on your heater the most. However, even the best heating systems will wear down over time. To avoid being caught in a chilly home this season, be aware of the warning signs of a malfunction so you can schedule furnace repair before the problem worsens.

What Are the Symptoms of a Failing Furnace?

1. Strange Noises

Loud banging noises are often the result of tiny gas explosions, which are not only dangerous in and of themselves but could crack other machinery. Rattling could indicate a loose component in the system, while a high-pitched noise could be a problem with the blower fan. Regardless of the sound, a professional should be called to determine the cause and to perform furnace repair.

2. Increase in Energy Bills

Have you noticed a dramatic rise in your energy bills? While it’s common for there to be an increase in the winter, if it’s much higher than in previous years, this may indicate a problem with your furnace. Clogged filters or faulty components may cause an HVAC unit to consume more energy, which also wears the system down faster.

3. Cold Air From Vents 

If your furnace is circulating unheated or cool air around your apartment, the blower fan may be broken, dirty air filters may be blocking the heat exchanger, or a breakdown may be imminent. First, make sure that the fan isn’t turned on. Then, try reigniting the pilot light. If both options fail to correct the problem, call a professional for help.
