Replacing Your Furnace Heat Exchanger: Factors to Consider

When it comes to the comfort of your home, the furnace heat exchanger plays a major role. It is the component responsible for producing warm air in your home, making it one of the most important parts of your furnace. Unfortunately, these heat exchangers can wear out over time and must be replaced. Here are seven tips to help you determine when to replace your furnace heat exchanger.

1. Age

A furnace’s heat exchanger can last up to two decades before needing to be replaced. If your furnace is nearing or has passed this age, it might be time to install a new heat exchanger.

2. Rust

As the heat exchanger ages, it can become susceptible to damage from moisture and wear. Rust can form on the surface of the exchanger, which can lead to a decrease in its efficiency and performance. If you notice any rust, it is important to replace the heat exchanger to guarantee its continued proper function.

3. Cracks

If you see any cracks or breaks in the heat exchanger, replace it immediately. It is important to do so as it can leak potentially hazardous gasses into your home. Be sure to be proactive in this regard.

4. Excessive Noise

If your furnace is louder than usual, it might be a sign that the heat exchanger is deteriorating. If you hear extra noise, it’s best to have it inspected immediately.

5. Reduced Efficiency

If your furnace isn’t providing enough warmth as it used to, it may indicate that the heat exchanger is not functioning properly. Other possible problems may cause decreased performance, so it is important to examine them.

6. Increased Energy Bills

If you have noticed that your energy costs are rising, this may indicate that your furnace is not operating as well as it used to. This could be due to a problem with the heat exchanger, which could be causing your system to be less efficient.

7. Carbon Monoxide Detector

If you hear your carbon monoxide detector beeping, it’s a sign that your heat exchanger may be allowing hazardous gasses to escape. This is a warning that you should change your heat exchanger as soon as possible to avoid any further danger.
