What Happens If A Wall-Mounted Air Conditioner Leaks Water?

What Happens If A Wall-Mounted Air Conditioner Leaks Water? A Comprehensive Guide by AirGreen

As a leading HVAC company in Montreal, AirGreen has a wealth of experience with wall-mounted air conditioners. One of the common issues our customers ask about is water leakage from their units. This article aims to shed light on why a wall-mounted air conditioner might leak water and how to manage this situation.

Understanding Wall-Mounted Air Conditioner's Operation

A wall-mounted air conditioner works by absorbing warm air from a room, cooling it via a set of coils, and then returning the cool air back into the room. During this process, condensation occurs, producing water. Normally, the water is collected in a drain pan and led away from the unit through a drain line. However, certain issues can lead to the water leaking out of the air conditioner instead.

Causes of Water Leakage from Wall-Mounted Air Conditioners

Water leakage from a wall-mounted air conditioner can stem from multiple sources:

  1. Clogged drain line: If the drain line gets blocked by dust, dirt, or mold, the water can back up and leak out of the unit.
  2. Incorrect installation: If the unit is not properly installed with a slight tilt towards the rear, water can leak into the room.
  3. Frozen evaporator coils: If the coils freeze, they can cause the drain pan to overflow, leading to water leakage when the ice melts.
  4. Cracked drain pan: Over time, the drain pan might crack, causing water to leak out.
  5. Air leaks: If warm air enters the unit and meets the cool air inside, it can lead to excess condensation and subsequent water leakage.

Implications of Water Leakage

When a wall-mounted air conditioner leaks water, it's not only inconvenient but can also cause several problems:

  • Structural damage: Continuous leakage can damage the wall around the unit, leading to peeling paint, warping, and in severe cases, structural deterioration.
  • Mold growth: The damp conditions can promote the growth of mold, which can affect indoor air quality and pose health risks.
  • Unit damage: Consistent water leakage can cause corrosion in the air conditioner, leading to a decline in performance or even a complete breakdown.
  • Increased operational costs: A malfunctioning air conditioner operates inefficiently, leading to higher energy consumption and increased utility bills.

What to Do if Your Wall-Mounted Air Conditioner Leaks Water

If you notice your air conditioner is leaking water, follow these steps:

  1. Turn off the unit: It's crucial to turn off the air conditioner to prevent further leakage and potential electrical issues.
  2. Inspect for visible issues: Check for blockages in the drain line, ice on the coils, or cracks in the drain pan. Remember, safety first – if you're uncomfortable performing these checks, contact a professional.
  3. Contact a professional: If you can't identify or fix the issue, it's time to call in a professional HVAC technician. At AirGreen, our team of experienced professionals can promptly diagnose and resolve the issue.

Preventive Measures

Prevention is always better than cure. Here are some preventive measures you can take to avoid water leakage:

  • Regular Maintenance: Regular professional servicing can ensure that your air conditioner runs efficiently and any potential issues are caught early.
  • Clean the air filter: Regularly cleaning or replacing the air filter can prevent it from getting blocked and causing the coils to freeze.
  • Inspect the drain line: Keep an eye on the drain line for any signs of blockages or damage.
