heating and cooling systemDuring the winter, your furnace is your best friend. If you want a warm and cozy house during the cold weather, you want to ensure your furnace is in tip-top shape. But even though the average lifespan of a furnace is around 20 years, furnaces can fail at any time. So how do you know when your furnace is starting to fail? Here are a few warning signs homeowners should keep an eye out for.

Increased heating bill: The first warning sign that something may be wrong with your furnace is that your heating bill has increased. Obviously, if you’ve been setting your thermostat to higher temperatures, your heating expenses are going to go up. But if you’ve been using your furnace consistently and you’re still seeing an increase in your bills, something may be wrong. If your furnace is trying too hard to maintain a certain temperature, it’s going to be using more energy. In this case, a furnace repair or replacement may be necessary to maintain your heating and cooling system‘s energy use.

Frequent repairs: While every furnace needs repairs now and then throughout its lifespan, you shouldn’t be having to schedule repairs too frequently. This is especially true if you’ve been scheduling repairs consistently over the past two years. Furnaces tend to show more breakdowns over the last two years of their life. So if you find yourself needing to replace or repair furnace parts fairly consistently, it may be time to replace it. This will allow you to save money in repairs while keeping your home comfortable.

Strange noises: For the most part, your furnace should be relatively quiet. Of course, it’s normal for furnaces to make some noise every now and then. But if you’re hearing strange noises like popping, banging, or rattling when you turn it on, there’s a good chance something is wrong. Parts can become loose or damaged in any heating and cooling system, which can prompt strange noises. So if you hear any unusual noises, make sure you schedule HVAC maintenance sooner rather than later.

Furnaces tend to last a long time with minimal issues when they’re properly taken care of. But if you notice any of these warning signs, make sure to contact an HVAC technician to check it out. Making necessary repairs can help keep your furnace running longer and more efficiently.
