7 Common Mini-Split Problems and How to Fix Them

July 12, 2021

Having mini-split installation done is an excellent way to solve comfort troubles in your house. These systems don’t have to have ductwork to deliver energy-efficient heating and cooling. Like any other home comfort system, they can run into issues occasionally. Here are seven of the most frequent 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 problem 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. Reach Booneville Heating & Cooling LLC at 662-269-8716 for support and we’ll get your drain unclogged promptly.

2. Mini-Split is Making Noise

Mini-splits typically don’t make much noise when they’re running. But there are two instances where they might create sounds.

  • Popping or clicking: This can be because of the plastic housing expanding or contracting while the system is operating.
  • Swooshing, crackling or gurgling: This can take place if your mini-split goes into defrost mode to keep itself from freezing up.

You shouldn’t be alarmed if you hear these noises as they’re typical. However, if your mini-split keeps switching into defrost mode, it’s a clue that something is off, like not enough refrigerant, a flawed circuit board or broken sensors. Your Booneville Heating & Cooling LLC HVAC pro will be able to locate and resolve the issue fast.

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

If your mini-split is not heating or blowing hot air, frozen coils could be the problem. Like we mentioned previously, iced-over coils could be the result of insufficient refrigerant, a failing circuit board or broken sensors. Reach us at 662-269-8716 for support.

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

If your mini-split is not cooling or blowing cold air, there could be a refrigerant leak. Your mini-split AC uses refrigerant to transfer heat and keep your home cold. These leaks must be resolved by a licensed HVAC technician, so reach us at 662-269-8716 for support.

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 might be halted by clogs in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very effectivelyis if it’s too large. A system that’s oversized will cool down a space too rapidly 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 grab 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 likely have a mold issue. Have a professional like Booneville Heating & Cooling LLC examine and rinse the condensate drain and drain line, if needed.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re likely encountering a refrigerant leak. Another certain sign that you don’t have sufficient refrigerant is a weak flow of chilled air. Call us at 662-269-8716 for assistance.

Fish

If your mini-split smells like fish, a couple of things could be wrong. In some situations this smell means there is an electrical problem or that there’s a leak. Nevertheless, call us at 662-269-8716 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 switch on. In many situations, replacing the batteries will fix the trouble. If you’re still having trouble, reach us at 662-269-8716.
