Your furnace is always there in your home, silently purring as it keeps powering the air system that flows throughout your home. However, there comes a time when it – like all appliances – has to go. The problem is figuring out when you should pull the trigger, so to speak, and swap it out for a new one.

If you do it too early, you might be splurging well before you actually need to replace your furnace. But wait too late, and your home could suffer from a malfunctioning unit and your air quality could decline as a result. Luckily, we’ve compiled a simple guide to knowing when it’s time for a replacement!

It’s Too Old

Most furnaces are designed with a shelf life of roughly 15 to 20 years in mind. Any longer, and you run the risk of it breaking down on you when you can least afford it. Your unit will begin eventually losing efficiency, and the performance will suffer more and more until it’s gone for good.

Repairs get costlier and more frequent, and eventually it gets to be too much trouble to pay for a repair instead of just replacing the unit. It’ll hurt your wallet, but a new unit will be much better than constantly forking over money for repairs.

Uneven Heating

As a furnace ages and deteriorates, it begins to struggle to evenly heat all the different rooms in your home. Some places will get absolutely blanketed with heat, while others might be as frigid as the weather outside.

If you’ve begun to notice that you walk from a hot room to a cold one pretty often, then a furnace replacement could be on the menu soon.

Lots of Weird Noises

While some noises are natural and aren’t a cause for concern, others indicate a severe problem. If your ears pick up on constant whirring, buzzing, rattling, humming or other sounds, then we’d recommend having someone come take a look.

You might have nothing to worry about, but it’s hard to know without an expert’s opinion. A professional will identify any problems and let you know the best course of action.

Unnaturally High Energy Bills

Obviously, you’ll begin to see some spikes in your energy bill when you use your furnace more than usual. But they shouldn’t be abnormally high. After you’ve begun settling in to using your furnace more frequently, see if the bills are still way higher than they usually would be. If they’re still far too expensive, it might be time to put in the call for a new unit.
