For starters not only will you have no heat in your home, but this almost always happens after hours, which means emergency, after hours repair costs. Not only this is this going to be more expensive, if it can’t be repaired and needs to be replaced you may be limited by your options based on what is available on short notice.

So, if your furnace is 15-20 years old it is probably living on borrowed time and for the reasons we mentioned above, it is always better to be proactive when it comes to replacing your furnace. There are some signs besides age that you should watch for to see if your furnace is on its last legs.

1. Your Furnace is 15 years or older

When your furnace reaches this age it may not stop working, but consider that by this age the heat exchanger has heated and cooled down approximately a million times in this life span. Consider that the heat exchanger is made of metal and it has expanded when heated and retracted when cooled over those 15 years. If you’re not sure how old your furnace is check for an inspection sticker, it should have the date it was inspected Over the years that wear and tear can take its toll and at this temperature fluctuation may cause the heat exchanger to crack over time. While this may not cause the furnace to shut down it can become an issue and may allow carbon monoxide to be released fro the furnace. That is why it is essential to get a furnace inspection each year, especially if you have an older furnace.

If your repair costs are adding up and you are furnace is consistently having problems its probably time to replace. Sometimes a furnace won’t break down and stop completely, it may continue to function but not to the best of its ability and overtime those repair costs can get to a point that it is better to replace the unit than continue to pump money into it. It is better to have a reliable safe unit.
