Why is My AC System Leaking Water?
Summer is heating up across the nation. The last thing you need is to crank up your AC only to find out that you’ve sprung a leak. But let’s not jump to conclusions. The issue might be simpler than you think.
What would cause water to leak from your AC unit into your home?
1. A Clogged Condensate Drain: This is, by far, one of the most common reasons why water might be leaking into your home. When this drain line becomes clogged from mold, grime, dirt, p[pollen or other debris it can result in an overflow of water pooling around your unit.
2. Faulty Drain Pan: The drain pan’s job is to catch excess water and condensation so that it doesn’t overflow and pool around your unit. However, these pans can corrode or become damaged (especially with older units).
3. Condensate Pump Failure: Some units utilize a condensate pump to pump excess moisture outside. If this pump breaks or begins to wear out, you may notice an accumulation of water in your home.
4. A Clogged or Dirty Air Filter: When the air filter is clogged, it reduces the airflow over the evaporator coil. In turn, this coil may freeze over. When the coil melts, excess water can drip down and overflow the drain pan.
5. Low Refrigerant: If your unit is low on refrigerant, it may lower the pressure in the system, causing the evaporator coil to freeze. When this melts, you’ll be left with excess water to deal with.
