Furnace Leaks: Common Causes and How to Fix Them

furnace

A furnace leak is a serious problem that can result in extensive damage to your home. Many different things can cause a furnace leak, and it is important to be aware of the most common culprits so that you can take steps to prevent them.

1. Cracked Heat Exchanger 

The heat exchanger is responsible for transferring heat from the furnace to the home. If it is cracked, it can cause the furnace to leak water or other fluids. It can also leak carbon monoxide, which is extremely dangerous.  

In some cases, a cracked heat exchanger can also lead to a fire. If you notice any cracks in your heat exchanger, it is important to have it repaired or replaced as soon as possible.

2. Clogged Condensate Line

The condensate drain line is responsible for carrying away water and other fluids that condenses on the heat exchanger. If it becomes clogged, it can cause the furnace to leak which can lead to water damage. It is important that you have it cleaned out as soon as possible.

3. Flue Pipe Problem

Another thing that can cause furnace leaks is a problem with the flue pipe. The flue pipe is responsible for carrying gases and other fumes away from the furnace, and if it becomes blocked, it can cause the furnace to leak. In some cases, a blocked flue pipe can also lead to a fire. If you notice that your flue pipe is blocked, schedule a cleaning immediately. 

4. Loose Connections

Another possible cause of furnace leaks is a loose connection. Furnaces have a lot of different connections, and if any of them become loose, it can cause a leak. 

This is usually an easy problem to fix, but it’s important to have a professional check it to make sure that there isn’t any other damage.

5. Venting System

The venting system is responsible for carrying gases and other fumes away from the furnace, and if it becomes blocked, it can cause the furnace to leak. In some cases, a blocked venting system can also lead to a fire. If you notice that your venting system is blocked, you should have it cleaned.

If you suspect that your furnace is leaking, it is important to have it inspected by a qualified technician as soon as possible.

6. Old Age

Over time, furnaces can develop cracks and other problems that can cause leaks. If your furnace is more than ten years old, it’s a good idea to have it inspected by a professional to ensure it’s still safe to use.

Conclusion

If you’ve been noticing water around your furnace, don’t ignore it. There are several potential causes of furnace leaks, some of which may cause serious damage to your property. 

If you’re unsure what’s causing the leak, it’s always a good idea to call a professional for help. They will be able to inspect your furnace and determine the leak’s source so it can be fixed.

Cody is very professional and knowledgeable. He responded quickly to my enquiry. He worked with us to ensure we could set up the ductwork and venting in a way that maximized the basement.

Climate experts came in for HVAC/boiler maintenance when we moved into our new house. They ended up finding a problem that went undiagnosed by our home inspection that could have been very dangerous. They then ended up installing a new boiler for us super quickly. It was obviously a sudden expense but Climate experts made the whole thing feel a lot better due to their professional and concern for our safety. The new boiler not only works, but is...dare I say...beautiful! The copper piping work that they did is a sight to behold. Who knew that we would be so excited to show our family/friends our cool new boiler. We absolutely recommend these folks—they are reliable, professional, and make even the typically boring part of the house feel nice and pretty. You are in good hands with them!
