AC Leaking? Scott’s Air Identifies Some Common Causes

As temperatures rise, Scott’s Heating & Air Conditioning urges customers to ensure their ACs are prepared for Florida’s scorching summer. There are a variety of things to check, but one common concern is a leak coming from the AC.

Moisture or a water leak

Moisture or a water leak around or near the AC system can indicate problems. Water pooling near your air conditioner is usually from the drain line backing up. Your air conditioner not only cools your home, but it also serves as a giant dehumidifier. The AC removes the humidity from your home and disposes of it through the drain line. If your AC is leaking, your drain line is either blocked or broken. Though not severe, it requires swift resolution to prevent potential issues like mold growth or property damage.

“A large number of service calls are related to AC leaks,” said Scott. “Although these leaks often tend to be relatively small, if left unchecked they can cause damage to walls or flooring, so it is best to get a professional opinion.”

Possible causes of a leaking AC are:

• Clogged drain line: A clogged drain line is the most common cause of water leaking from your AC into your home. If the drain line becomes clogged with dust, dirt, sludge or mold, the water can back up into your home. The good news is that unclogging the drain line should be an easy fix.
• Dirty air filter: A dirty air filter blocks airflow over the evaporator coil causing the coil to get too cold and freeze. When it melts, it can drip more water than the pan can handle. The solution is to check your air filter and replace it if it is dirty. We recommend changing the air filter every month.
• Damaged or rusted drain pan: With older AC units, the drain pan may deteriorate, allowing water to escape through holes, causing leaks. Again, in most cases, replacing the pan is easily done by a qualified technician.
• Low refrigerant: Similar to a dirty air filter, low refrigerant will lower pressure in the AC system, causing the evaporator coil to freeze over. When the coil melts, water overflows the drain pan. You’ll notice you’re low on refrigerant when the AC isn’t cooling well or you hear a hissing noise (indicating a refrigerant leak). Leaking refrigerant is remedied by either having the leak repaired or replacing the coil.

“I always suggest to customers when they’re having a water leak that the first thing they need to do is check that the drain line is draining properly,” said Scott. “If you’re still having a leak, it is time to contact Scott’s Air to inspect your AC. We are here to make sure your summer is as cool and comfortable as possible.”
