When it comes to odd places to find water in your house, under your furnace would probably top that list. While finding water under your furnace can be a cause for concern, it doesn’t always mean costly repairs. There are a few reasons why you might have a wet floor under your furnace, and luckily some of them can be easily fixed without calling a repairman.
Find the Source of Water
The first thing you want to do is to find out exactly where the water is coming from. Making sure that it’s not standing water that has leaked from pipes, your foundation, or something else (like your water tank or washing machine) will make things easier for you to pinpoint and repair. Once you’re positive it’s coming from the furnace, it’s time to look at the possible causes and solutions.
Reasons Why Your Furnace is Leaking
- The floor drain may be clogged. It may be something as simple as a clog in the drain around your furnace where condensation is drained away. Clear the floor drain of dirt, debris, and obstructions regularly to help reduce backups and flooding.
- Pipes may be improperly insulated or taped. If it’s been awhile since your condensation-bearing pipes have been checked, cleaned, and repaired, the insulation or tape around them may be wearing out, allowing condensation to form. Routine maintenance and checking of these pipes can help keep things running smoothly, and prevent water from pooling.
- Your A/C’s internal drain may be clogged. If your A/C shares an internal drainage pipe or system with your furnace, a clog can be a good possible cause of standing water on your floor. These clogs can form easily without regular service, and do require a professional to check them.
- You may have an issue with your flue pipe. If your flue pipe is in bad shape or is improperly sized, this can allow condensation to build up inside the furnace system itself and then pool on the floor. Problems with your flue are best checked and serviced by a professional to ensure everything is done properly and reduce future issues.
These are some of the more common reasons why you might have water pooling under your furnace. Doing regular maintenance can help tremendously in decreasing the likelihood of costly repairs in the future. Having tune-ups and regular servicing can help increase your system’s efficiency, reduce utility costs, and save you money in the long run!
