Most people put off furnace replacement until the old unit breaks down beyond repair. This can be a major mistake, though. Instead, consider taking a proactive approach and replacing your furnace sooner rather than later if any of the following issues apply to your heating unit.

1. It's Noisy

It can be a nuisance dealing with a noisy furnace. If it is constantly banging, squealing, or rattling, there is likely something wrong with it. If repeated maintenance calls aren't addressing the issue, then replacement may be a good idea. Some furnaces don't bang or bump, but they just hum loudly due to an aging blower. If this is annoying you, then replacing the furnace can make your home much more pleasant.

2. It's Expensive

Is your furnace costing an arm and a leg to run, or are constant repair issues causing a major drop in your bank balance? If so, then it's time to replace the furnace. One option is to install a more efficient style of furnace, such as a heat pump, so that you don't have to spend as much on energy bills. Plus, a newer furnace shouldn't have a lot of repair costs, and what repairs that are necessary are more likely to fall under the warranty.

3. It's Performing Poorly

Poor performance doesn't immediately mean you need to replace the furnace. Sometimes a tune-up or minor repair solves the problem. For example, a furnace that heats poorly may only need a new thermostat. On the other hand, poor performance can also be the result of more major problems in the furnace itself, such as a failing motor. Weigh the cost of repairs against the expected life of the furnace to determine whether it makes sense to repair or replace a poorly performing unit.

4. It's Old

It's a simple fact that an older furnace is not as energy efficient as a newer model. If your furnace is leading to high energy bills, then it may be time to upgrade to a more energy-efficient, modern model. Older furnaces are also more prone to unexpected breakdowns, especially in the midst of winter when they are working overtime. If going without heat for any length of time is a concern, then update an old furnace before problems arise.

5. It's Undersized

Homes can evolve over time. You may build additions and expand the square footage of the home, or you may take down or put up walls and change the airflow patterns throughout the home. These changes can lead to your furnace working harder because it is undersized for the new layout and size of your home. In this case, replacement is necessary.
