It may come as a surprise when your furnace begins to stop in the middle of winter, causing the temperature to drop in your home. However, what could cause your furnace to stop working during the time you need it the most?
Clogged Furnace Filters
One of the most common reasons why a furnace has stopped working correctly is a clogged furnace filter. Often, homeowners don’t really think about their filter and change it maybe once a year. Changing the filter only once a year isn’t enough as a clogged filter can make the furnace work harder and overheat which shortens the unit’s lifespan. If the heat exchanger is constantly overheating for long periods of time, this could potentially cause a fail in the metal exchanger. Cracks or holes can begin to appear which could create a dangerous living situation as carbon monoxide could possibly start leaking out. Since there are no set rules on how often you should change your furnace filter, it’s a smart idea to bring in a professional to give your system a checkup. They’ll know your system and can offer advice as to how often you can change your filter, so your home stays at a comfortable temperature.
Have you noticed that your furnace has been making a lot of unusual noises such as banging, squeaking, rattling or clanking? This could be a sign that there are some mechanical issues with your equipment, such as the fan belts being loose or worn out. In this instance, your best bet is to contact a professional as waiting could make the problem even worse. A professional will be able to determine the problem, the cause of the sounds, and how to fix the problem.
Thermostats that are broken or old can send the wrong signals to your furnace causing different heating issues in your home. If your thermostat takes batteries, try changing the batteries. If the issue persists, trying upgrading to a newer thermostat to keep your home at a comfortable temperature. One important note is that upgrading to a smart thermostat can help future heat troubles. Smart thermostats actually track the heating and cooling as well as save energy.
