Ductless mini splits offer a convenient way of cooling and heating homes without using ductwork, yet they can sometimes experience issues.
Water leakage can be one of the most bothersome issues, yet it often can be easily rectified using essential tools at home.
If your mini-split is leaking water, you should contact a professional HVAC company, like Anderson Air, if you want to get the job done quickly and professionally.
1. Dirty Evaporator Coils
Evaporator coils transfer heat from your home’s air into the refrigerant, but over time they may become dirty, creating issues for both efficiency and operation of a mini-split system. Luckily, cleaning these coils using household products or tools should be possible.
A blocked drain line could also cause leaks from an evaporator coil. Water from your coils travels down this channel into a drip pan for collection, but if the latter becomes full of debris, it may overflow and overflow its boundaries.
Your evaporator coils can be easily cleaned using compressed air or a mixture of water and mild detergent or using a toothbrush and scrubbing the coils with a mild soap solution.
Be sure to shut off the power before cleaning; otherwise, a professional may need to inspect and diagnose your system and help fix any more significant problems beyond your capabilities.
2. Clogged Drain Line
Drain lines in ductless mini splits serve to transport condensation that forms on evaporator coils into an indoor unit and, ultimately, out through its drain line to outside drainage lines.
When this drain line becomes blocked or blocked with debris, that accumulated moisture may leak down your walls instead.
Clogged drainage lines can often be easily fixed. To start off, disconnect the power to the unit and locate its drain pan. Next, unscrew the cap on the drain line and pour a cup of bleach down it.
Wait an hour or two, and run clean water down it before trying another solution like baking soda and lemon juice cleaner – perhaps that will do the trick and restore your AC back into working order!
3. Damaged Drain Pan
Your air handler’s indoor unit contains a drain pan that collects any dripping from evaporator coils, and when this pan becomes full, it may overflow and leak out through its bottom openings.
To safely empty this pan yourself, you will want to ensure your system is turned off first before emptying the box yourself.
Ensure that your air handler’s drainage holes are unblocked by dirt or other debris, and if your indoor unit includes a condensation pump, check that it’s working correctly.
If your ductless mini split is leaking water, it’s crucial that it be repaired immediately, as this could lead to severe property damage and mold or mildew growth in your home.
If the problem can’t be rectified independently, professional AC technicians should be called in. They will be able to assess and help resolve it swiftly.
4. Dirty Air Filter
As your ductless AC system cools the air in your home, humidity turns to water (condensate) on its evaporator coils and drips down to a drain pan for collection and disposal through its condensation line.
Should this line become clogged or damaged and no longer function as designed your indoor air handler will leak water instead.
Filthy air filters reduce airflow efficiency across the system, including to evaporator coils where they block airflow over them and can even lead to them freezing over – creating a severe threat that requires professional assistance to address.
Although having a mini split that leaks can be annoying, most issues are easily remedied. Ensure you follow your owner’s manual’s maintenance guidelines or contact an AC specialist if further problems arise.
Addressing a leaky AC unit as quickly as possible will improve its comfort and longevity – the sooner addressed, the faster you’ll have peace of mind knowing your equipment won’t break down on you!
