Ever heard the phrase “aged like a fine furnace?” Us either. That’s because while furnaces can last a while, they certainly don’t age as gracefully as wine. The age of your furnace is one of the biggest indicators that it’s time for a new one. The lifespan of most furnaces can be as little as about 15 years and as high as 20 years. If your furnace is still going strong but it’s between 15 and 20 years old, it’s worth keeping an eye on. If your furnace is between 15 and 20 years old and it’s not heating quite like it used to, then give our HVAC services a call.

Higher Bills

When furnaces start to go bad, they may have to work harder to provide the same heating performance as before. The harder your furnace is working, the higher your utility bills will be. If you notice a sudden spike in the energy bill, it’s worth investigating if your furnace is the source and having HVAC services replace it if that’s the case.

Concerning Sounds

This sign is probably the most obvious of the five on the list. If your furnace is going bad, you may hear loud clanking, banging, or generally unpleasant noises that it’s never made before. Before you rush to call HVAC services, make sure your toddler isn’t playing drums on it or the noises can’t be attributed to anything else. When it is for sure the furnace making the noise, it’s likely time for a new one.

Frequent Repairs

Another common sign it’s time for a new furnace is frequent repairs. If you are on a first-name basis with your HVAC services provider because they spend a lot of time fixing your furnace, it could be time to ditch the old furnace for a newer model. Plus, think about it — you’ll spend more money constantly repairing your existing furnace after a while than you would be replacing it altogether.

Poor Heating

Last but not least, if your furnace is having a tough time heating your home to the set temperature, it may be time to replace it with a new one. Unless you are setting your thermostat to 90 degrees, your heater should be able to accommodate. As your furnace struggles to heat your home to 70 degrees, it is likey telling you it’s reached the end of the road and it’s time for a new one.
