When water accumulates near your furnace, it could indicate an issue. The type of problem could depend on its age and type and when you installed it. High-efficiency furnaces may produce condensation that must be properly drained away, while an old furnace may lack adequate slope to provide proper ventilation. Here are some of the reasons behind the furnace leaking.
Clogged Condensate Drain Line
If you find a pool of water accumulating near or underneath your furnace, don’t be alarmed; this is entirely normal and may be due to clogged drain lines or pans. Over time, the external hose that collects condensation from a heat exchanger may become clogged with dirt and debris due to lack of regular cleaning and replacement.
However, this should be an easy problem to remedy by using wire hanger or pipe cleaner to dislodge any blockages and empty out clogged lines; failing that, use wet-dry vacuum to extract any remaining liquid out. Leakage due to this is one of the primary reasons a furnace leaks water. Here are some of the common furnace issues.
Malfunctioning or Broken Condensate Pump
Modern high-efficiency condensing furnace systems produce condensation that must be drained off, typically via a PVC exhaust pipe or additional tubing designed for this purpose. If this tubing becomes disconnected, damaged, or clogged, condensation could leak around the base of your furnace and damage its components.
Standing water around or accumulating on your furnace is a sure sign of issues and should be addressed by an HVAC service expert immediately. The first step should be locating the shutoff switch (usually located next to your unit or at its power source) or turning off the power at your breaker panel; remaining stagnant water can quickly cause severe damage. Once these steps have been completed, identify where it’s leaking from.
Humidifier Leak
Leaks in the humidifier are one of the primary culprits behind water leaking around furnaces. High-efficiency gas furnaces generate condensation on their evaporator coil, which should generally drain into a furnace drain line that empties onto either floor drains or other forms of drainage systems.
- When these lines become clogged or damaged, condensation backs up into them and leaks around the furnace, causing water to pool around it.
- Puddles of water near your furnace can be unnerving.
- You might think it signals significant problems or that your heating system has stopped functioning altogether, and it could become very alarming.
- However, the good news is that most water leaks around a furnace are harmless and can be resolved quickly.
Leaking Exhaust Vent or Flue Pipe
Vent and flue pipes for furnaces are essential in safely venting combustion byproducts such as carbon monoxide from your home and ensuring peak furnace efficiency. A properly functioning vent pipe ensures this.
Your furnace’s exhaust pipe uses the natural rise of hot gases to expel them out of your home. However, if the exhaust pipe is too small or improperly sloped, its gases could cool off and condense into water within itself, causing serious disruptions in performance and wasting valuable heating fuel.
Condensation usually drains down through either a floor drain or a condensation pump; however, any problems with either can cause leakage. High-efficiency furnaces that produce more condensation are particularly susceptible. Here are some ways to tell if your furnace is leaking gas.
Improperly Installed Furnace Drainage System
High-efficiency furnace drain systems are intended to allow condensation to form and be safely drained away. However, if a drain hose becomes clogged or an improper installation results in more water being drawn back towards the furnace, it can cause leaks and further inconvenience.
- Homeowners should watch for early signs of condensate drain issues.
- These signs include puddles around their furnace, musty smells in their home, and visible condensation on windows.
- If these symptoms emerge, homeowners should immediately turn off their furnace, check for blockages.
- Contact Green Street HVAC—doing so may prevent significant and expensive damage and bio-growth that is harmful to their family’s health.
Issues With the Air Conditioning System
Clogged or malfunctioning air conditioner drain lines can often leak water around a furnace, necessitating HVAC service to address. High-efficiency furnaces produce condensation that must be drained using a condensate line or pump. Failure of either could result in water seeping into the base of your furnace and flooding its interior space with moisture.
If you notice water pooling around or inside your furnace, switch it off immediately and try to clear away as much as possible before calling an HVAC professional for repair services. Doing this will allow them to determine what caused the leak and address it accurately.
Furnace Heat Exchanger Problems
For maximum efficiency, condensing furnaces use condensation as part of their heating process, creating moisture for use within your furnace and ultimately leading to water leaks within its walls. Over time, this moisture will build up and become trapped, eventually leading to water leakage into your unit and potentially to expensive repairs or fire hazards!
No matter how old or new your furnace may be, water leaks should always be addressed as soon as they appear to prevent further damage to it and other parts of your home. Furthermore, they create the perfect conditions for mold growth, which threatens health and leads to costly repairs. Leaks from furnaces could also indicate carbon monoxide leaks, which should also be addressed promptly by an HVAC specialist.
Damaged Furnace Filter or Pan
Leaks in furnaces can be an expensive hassle. They may lead to bio-growth that poses health and property risks, and damage may also occur due to constant leakage. If your furnace leaks water, it could be due to issues with the secondary heat exchanger.
Such leaks can compromise the efficiency of your heating system and should be addressed promptly. Leaks around the base of your furnace should never be taken lightly and should be dealt with quickly by professionals. First, shut off your furnace and use napkins or towels to soak up any pooled water; alternatively, a wet-dry vacuum can extract it.
Change your air filter regularly to help avoid this issue. Clogged filters allow contaminants into your system and compromise indoor air quality, making it harder for your AC unit to function effectively.
Conclusion
Water leaks around your furnace can often be alarming, but in most cases, they are manageable and preventable with timely care and maintenance. If your furnace is leaking water, it might be due to issues with the condensate drain hose. Regular checks and cleaning of the condensate drain hose can help avoid water leaks and ensure your furnace operates efficiently.
