Why Is My A/C Unit Leaking Water? | HVAC Tips

by Daniel Estevao on August 21, 2015

A leaking A/C unit can be confusing and troublesome. It’s normal for the dehumidifying process to create some condensation. However, when pools of water form, you’re left asking, “why is my A/C unit leaking water?”

Ignore the problem for too long and you could end up with water-damaged ceilings and floors.

Why Is My A/C Unit Leaking Water?

Several things can cause your air conditioner unit to leak, and most of the time you can stop the leaks yourself. However, consult an HVAC professional to ensure repair. Remember, an ounce of prevention is worth a pound of cure — ask about Pacifici Air System’s preventative maintenance service.

  • Busted Pump

Leaking water could be a sign that you have a busted condenser pump. To check whether you have a broken pump, pour water into the condenser pan. This tells you if the pump is properly pumping out the excess water. If it’s not, check your power. If your power’s good, you’ll probably need to repair the motor or the condenser itself.

  • Improper Installation

If an air conditioner is improperly installed, it will not be flat. Check your unit to make sure it’s level.

  • Too Much Pressure

Closed and blocked vents create troublesome pressure within your unit. This pressure causes your A/C unit to leak water. Inspect your vents to ensure they’re not closed or blocked.

  • Clogged Drain Hole

The drain that removes water from the unit can somethings clog. Clear any blockage and the leaking should stop.

  • Cold Outdoor Temperatures

When the air outdoors gets too cold for the water to evaporate, it’ll begin to pool up. When it gets hot again, the water should evaporate.

  • Bad Seal

Too much warm air can enter if there are loose or bad seals. Because this warm air condenses with the cold air inside your unit, a pool of water forms under your unit. Resealing can solve this issue.
