⚠️ Safety First

  • Turn off the air conditioner and unplug it before any maintenance.
  • Be careful around the aluminum fins — they are sharp and bend easily.
  • Never attempt to recharge refrigerant yourself — this requires a licensed technician.

Step-by-Step Repair

  1. Step 1 of 6
    1

    Identify where the leak is coming from

    Dry up any standing water, then place paper towels or newspaper around the base of the unit. Run a short cycle and watch carefully to identify exactly where the water is coming from. This is the most important step.

  2. Step 2 of 6

    Check all hose connections

    Inspect every hose connection — inlet, outlet, and drain. Tighten any loose fittings by hand. Look for cracked or worn hoses that need replacement (usually $10-$20).

  3. Step 3 of 6

    Inspect seals and gaskets

    Check the door seal, gaskets, and O-rings. Look for cracks, tears, warping, or buildup. Clean seals with warm soapy water. Replace any that are visibly damaged.

  4. Step 4 of 6

    Check the drain system

    Make sure the drain isn't clogged. Clean any accessible filters or drain traps. A backup in the drain can cause water to overflow from unexpected places.

    Level the unit

    If the unit isn't level, water can pool and leak from places it shouldn't. Use a bubble level on top and adjust the feet until it's even.

    Test and monitor

    After making repairs, run a full cycle and watch for leaks. Place a dry towel underneath to easily spot any remaining drips.

If That Didn't Work

  • A dirty air filter is the #1 cause of AC problems — clean or replace it first.
  • The condenser coils may be dirty — clean them with a garden hose.
  • The thermostat may not be set correctly or the sensor may be displaced.

When to Call a Professional

If the compressor isn't running or you suspect a refrigerant leak, you'll need a licensed HVAC technician. Refrigerant recharge costs $150-$400. Compressor replacement on a window unit usually isn't worth it — a new unit costs $150-$500.
