Why Your Air Conditioner Is Still Leaking Water After Cleaning

January 24, 2026

Recently, we’ve seen many Gold Coast customers dealing with air conditioners still leaking water even after cleaning. It’s frustrating when a service that should fix the issue doesn’t and water keeps dripping where it shouldn’t. Let’s explore why this happens and find the right solution with DEEPCHILL, your trusted residential and commercial air conditioning Gold Coast specialists!

Real stories from customers

One homeowner shared their frustration on Facebook. He said after their split system air conditioner started leaking water right after a professional clean. Before the service, the unit worked fine. But after running it for about 5 hours, water began dripping heavily. They checked everything they could but nothing worked out. When they raised the issue, the cleaner suggested the unit might just be “working too well” and producing extra condensation. 

Another Gold Coast resident shared a similar story. Their AC had been leaking badly for a while with water running down the wall and into the carpet. A cleaning company told them it was likely a blocked drain and carried out a full internal wash, even placing a large bag underneath to catch the water. For a few weeks, the problem seemed solved. But then the leaking came back.

Top 3 reasons why your AC is still leaking water even after cleaning

  • Incomplete or careless cleaning: Some services only clean visible parts. If the drain line, drain pan or hidden corners are missed, water can still build up and leak, especially in humid air conditioning Gold Coast conditions.
  • The indoor unit is slightly tilted: If the unit isn’t level and no one checks it during cleaning, water won’t flow toward the drain properly. Instead, it spills over and leaks inside.
  • Cracked or misaligned drain tray: Even with a clear drain line, a damaged or shifted drain tray can’t guide water correctly. This often goes unnoticed during basic cleans and leads to ongoing leaks.

How DEEPCHILL can fix AC leaking water properly

When an AC is still leaking water after cleaning, the problem is often not the clean itself, but how rushed or incomplete it was. DEEPCHILL’s preventative maintenance is designed to go deeper and remove the hidden causes that basic cleaning often misses.

Our technicians don’t rely on shortcuts. Every service starts with proper home protection, using drop sheets, wall sheeting and professional hydro clean bags to fully control runoff water. This prevents new leaks, wall stains or moisture damage during servicing – something many customers experience after quick cleans.

More importantly, DEEPCHILL follows a structured, step-by-step process. We flush the drain line to remove hidden buildup, carefully clean the evaporator coil and fan chamber where moisture often lingers, and check airflow issues caused by dirty filters. These steps directly target the most common reasons an AC keeps leaking water even after cleaning.

We also take the time to inspect installation details that are easy to overlook. If the indoor unit is slightly tilted or the drain tray is cracked or misaligned, water will never drain properly. DEEPCHILL technicians look for these issues during preventative maintenance instead of assuming everything is fine. By combining thorough cleaning, careful approach, DEEPCHILL’s preventative maintenance helps residential and commercial air conditioning Gold Coast systems stop leaking water.

If your air conditioner is still leaking water after cleaning, it’s a clear sign that something deeper is being missed. From hidden drainage issues to installation problems and incomplete servicing, small oversights can quickly turn into ongoing water damage. Ignoring it only increases the risk to your walls, ceilings and system performance.

Whether it’s commercial or residential air conditioning Gold Coast, DEEPCHILL is here to help. If your system is still leaking water, don’t wait for it to get worse. Contact DEEPCHILL today and let our experienced technicians take care of it properly!
