What Causes Cracked Furnace Heat Exchanger?
1. Improper Installation
If the furnace is not installed properly, it may put stress on the heat exchanger which can lead to cracks over time. This can also occur if the furnace is not properly supported or fastened to the floor.
2. Age and Wear and Tear
Heat exchangers can weaken over time due to regular use, so if you have an older model furnace it may be more likely to crack than a newer one. Also, if the furnace is used more regularly than recommended it could also cause cracks due to excessive heat.
3. Poor Ventilation
If your ventilation system is inadequate or not up to code, there may not be enough airflow for the furnace to operate safely. This can lead to overheating which can put too much stress on the heat exchanger and cause it to crack.
4. Corrosion
If the furnace is not properly maintained, corrosion can build up on the heat exchanger which can weaken it and lead to cracks over time. It is important to have your furnace serviced regularly in order to prevent this from happening.
5. Heat Cycles
When a furnace is constantly switching from heating to cooling and back again, it puts extra stress on the heat exchanger which could cause cracking or other damages. Also, if the thermostat settings are incorrect it could cause the furnace to cycle too often and lead to cracks in the heat exchanger.
Why is It Important to Fix a Cracked Furnace Heat Exchanger?
1. To Prevent Carbon Monoxide Poisoning
Furnaces typically burn natural gas or heating oil, which can produce dangerous carbon monoxide gas. A cracked heat exchanger allows the toxic gas to leak into your home’s air supply, where it can cause serious health problems and even death if left unchecked.
2. To Prevent Further Damage to Your HVAC System
A cracked heat exchanger will not only reduce the efficiency of your furnace and cause it to use more energy but can also lead to further damage if it is not replaced or repaired. Left unchecked, a cracked heat exchanger can cause adjacent components in your HVAC system to break down, including the ignition system and compressor.
3. It Is Cost Effective
If you have a cracked furnace heat exchanger, it is important to fix it as soon as possible. A quick repair or replacement can save you from costly repairs and replacement parts in the future. Additionally, fixing your heat exchanger will help your HVAC system run more efficiently and reduce energy use, resulting in lower energy bills.
In order to ensure your furnace is operating safely and efficiently, it is essential to fix a cracked heat exchanger as soon as possible. If you suspect that your system has a cracked heat exchanger, contact an experienced HVAC technician for a thorough inspection.
How to Fix a Cracked Furnace Heat Exchanger in 5 Easy Steps
Now that we know what causes cracked furnace heat exchangers, let’s look at how to fix them. Depending on the severity of the crack, there may be several options available for repairing it.
Step 1: Identify the Location of the Crack:
Inspecting a furnace heat exchanger requires special tools and protective gear, as it can be extremely dangerous to work in this area without taking appropriate safety precautions. It’s important to identify the exact location of the crack in order to determine the best way to fix it.
Step 2: Choose a Repair Method:
Once you’ve identified where the crack is located, it’s time to decide on a repair method. If the crack is small, you may be able to use epoxy or solder to patch up the area and seal off any gas leaks. However, if the crack is larger and more severe, you may need to replace the entire heat exchanger or a section of it.
Step 3: Prepare for Repair:
Before attempting any repairs, it’s important to turn off all power and gas lines leading to the furnace. This will ensure your safety during the repair process.
Step 4: Perform the Repair:
Depending on your chosen repair method, this will involve soldering or epoxying the crack closed. If you’re replacing a section of the heat exchanger, you will need to properly secure it in place and make sure all connections are tight and secure before turning back on the gas and power lines.
Step 5: Test the Furnace:
Finally, once your repair is complete, it’s important to test the furnace to make sure it is working properly. This can be done by turning on the furnace and checking for any potential gas or air leaks. If everything appears to be working correctly, you can turn off the power and gas lines and consider your repair a success!
Fixing a cracked furnace heat exchanger is not an easy task, but if done correctly it can be quite rewarding. With these five steps, you’ll be able to assess the damage, choose a repair method, prepare for repairs, perform the repairs, and test the furnace to make sure everything is in working order.
With a little bit of patience and attention to detail, you can have your furnace back up and running in no time!
