7 Common Mini-Split Troubles and How to Resolve Them

July 12, 2021

Having mini-split installation done is a smart solution for solving comfort issues in your residence. These systems don’t need ductwork to give energy-efficient heating and cooling. Like any other home comfort system, they can experience problems occasionally. Here are seven of the most frequent mini-split problems 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 an issue with the condensate drain or drain line. It’s typical for a drain line to be clogged with mold, force water to back up and leak. Reach Woody's Sudden Service Inc at 703-278-2036 for support and we’ll get your drain unclogged quickly.

2. Mini-Split is Making Noise

Mini-splits normally don’t create a lot of noise when they’re operating. But there are two situations where they might produce sounds.

  • Popping or clicking: This can be due to the plastic housing expanding or contracting while the system is running.
  • Swooshing, crackling or gurgling: This can take place if your mini-split switches into defrost mode to stop itself from icing up.

You shouldn’t be worried if you hear these noises since they’re expected. However, if your mini-split keeps turning on defrost mode, it’s a clue that something is wrong, like insufficient refrigerant, a faulty circuit board or malfunctioning sensors. Your Woody's Sudden Service Inc HVAC technician will be able to locate and solve the situation quickly.

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

If your mini-split is not heating or blowing hot air, frozen coils may be to blame. Like we discussed prior to this, frozen coils might be the consequence of not enough refrigerant, a bad circuit board or broken sensors. Reach us at 703-278-2036 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 comfortable. These leaks must be fixed by a licensed HVAC professional, so reach us at 703-278-2036 for assistance.

5. Mini-Split is Not Dehumidifying

Like an air conditioner, a mini-split does a great job at dehumidifying during the summer. However, this may be halted by mold in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying properlyis if it’s too large. A system that’s too big will cool down a room too quickly without having a chance 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 tell you that something is wrong. Here are five of the most typical 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 Woody's Sudden Service Inc inspect and flush the condensate drain and drain line, if required.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re likely dealing with a refrigerant leak. Another sure clue that you don’t have enough refrigerant is a low concentration of cold air. Contact us at 703-278-2036 for help.

Fish

If your mini-split smells like fish, a few things could be wrong. Sometimes this smell means there is an electrical problem or that there’s a leak. Regardless, call us at 703-278-2036 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 most instances, replacing the batteries will resolve the issue. If you’re still having trouble, contact us at 703-278-2036.
