Is your furnace leaking water? If so, you could have a potentially serious problem on your hands. Water can cause extensive damage to homes in Charlotte, NC. Andersen Heating & Cooling has some tips to identify and eliminate the causes of a leaky heating system.

Condensation could be the culprit

The most common cause of a furnace leaking water is condensation. This is particularly a problem with high-efficiency heating systems. If your heating system’s yellow tag states a 90%+ AFUE rating, or if there is a white pvc pipe coming from it, it’s high efficiency. These systems operate by cooling combustion gases, which ultimately causes condensation. Condensation itself is normal and simply exits your home through a drain. However, if the drain is clogged, or there is a break in a condensation line, this water has nowhere to go and forms a puddle around your furnace.

Humidifiers may have a hand in it as well

Does your HVAC system have a humidifier? If so, it may be the source of your water dilemma. Humidifiers can greatly increase efficiency for heating systems during winter months. On the other hand, they can be susceptible to wear and tear that can lead to significant water leakage. As with the furnace itself, humidifiers can be affected by clogged drains. Other issues include dirty filters and cracked tubing and hardware.

What should I do about my furnace leaking in Charlotte?

Water damage is no laughing matter for any home. It can severely damage your HVAC system and the structure of your house, and it promotes the spread of mold and mildew. Fortunately, it’s pretty easy to prevent these catastrophic conditions in your home. You should contact an HVAC technician as soon as you notice water build-up, but it’s even better to schedule routine maintenance ahead of time. Monthly filter changes are essential for any heating and air system, and regular inspection can detect potential problems before they require costly repairs.
