7 Common Mini-Split Problems and How to Resolve Them

July 12, 2021

Having mini-split installation done is a smart way to solve comfort troubles in your residence. These systems don’t have to have ductwork to deliver energy-efficient heating and cooling. Similar to any other home comfort system, they can experience issues occasionally. Here are seven of the most typical mini-split issues and how you can resolve them.

1. Mini-Split is Dripping Water or Not Draining Water

If your mini-split is dripping water or not draining water, there may be a situation with the condensate drain or drain line. It’s expected for a drain line to become clogged with mold, force water to back up and spill. Contact Stanford Heating & Cooling at 812-825-8695 for support and we’ll get your drain unclogged rapidly.

2. Mini-Split is Making Noise

Mini-splits typically don’t generate much noise when they’re operating. But there are a couple of situations where they could create sounds.

  • Popping or clicking: This can be due to the plastic housing expanding or contracting while the system is on.
  • Swooshing, crackling or gurgling: This can take place if your mini-split turns on defrost mode to prevent itself from freezing over.

You shouldn’t be worried if you hear these noises as they’re expected. However, if your mini-split keeps turning on defrost mode, it’s a hint that something is wrong, including low refrigerant, a flawed circuit board or broken sensors. Your Stanford Heating & Cooling HVAC professional will be able to pinpoint and resolve the problem fast.

3. Mini-Split is Not Heating or Blowing Hot Air

If your mini-split is not heating or blowing hot air, icy coils could be the problem. Like we talked about prior to this, frozen coils could be the result of low refrigerant, a faulty circuit board or broken sensors. Reach us at 812-825-8695 for help.

4. Mini-Split is Not Cooling or Blowing Cold Air

If your mini-split is not cooling or blowing cold air, there might be a refrigerant leak. Your mini-split AC uses refrigerant to transfer heat and keep your house cold. These leaks must be resolved by a licensed HVAC pro, so call us at 812-825-8695 for assistance.

5. Mini-Split is Not Dehumidifying

Similar to an air conditioner, a mini-split does a great job at dehumidifying during the summer. However, this could be interrupted by blockages in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very effectivelyis if it’s oversized. A system that’s too big will cool down a room too quickly without having time to dehumidify it. Mini-split size is planned on square footage and BTUs.

6. Mini-Split Smells

If your ductless mini-split smells, it’s trying to get your attention that something is wrong. Here are five of the most usual smells and what they mean.

Musty, Sour or Mildew

If your mini-split smells musty, sour or like mildew, you could have a mold issue. Have a pro like Stanford Heating & Cooling check and rinse the condensate drain and drain line, if required.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re probably dealing with a refrigerant leak. Another surefire clue that you don’t have enough refrigerant is a lack of cold air. Contact us at 812-825-8695 for support.

Fish

If your mini-split smells like fish, a few things could be wrong. Sometimes this smell means there is electrical trouble or that there’s a leak. Nevertheless, call us at 812-825-8695 for help.

7. Mini-Split Will Not Power On

If your mini-split will not power on, look at the remote first. If the batteries are out of juice, your mini-split won’t run. In many experiences, replacing the batteries will solve the issue. If you’re still having trouble, reach us at 812-825-8695.
