7 Common Mini-Split Problems and How to Fix Them

July 12, 2021

Having mini-split installation done is a wise approach to solve comfort troubles in your home. These systems don’t need ductwork to provide energy-efficient heating and cooling. Like any other home comfort system, they can have problems from time to time. Here are seven of the most common mini-split issues and how you can fix them.

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

If your mini-split is dripping water or not draining water, there might be a problem with the condensate drain or drain line. It’s common for a drain line to get clogged with mold, force water to back up and spill. Call Air Quality Solutions at 614-871-4144 for support and we’ll get your drain unclogged quickly.

2. Mini-Split is Making Noise

Mini-splits normally don’t generate much noise when they’re running. But there are a couple of times where they might produce 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 happen if your mini-split goes into defrost mode to stop itself from freezing up.

You shouldn’t be alarmed if you hear these noises as they’re typical. However, if your mini-split keeps turning on defrost mode, it’s a clue that something is off, including insufficient refrigerant, a flawed circuit board or malfunctioning sensors. Your Air Quality Solutions HVAC technician will be able to pinpoint and correct the issue rapidly.

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 the problem. Like we talked about prior to this, iced-over coils can be the result of insufficient refrigerant, a faulty circuit board or defective sensors. Contact us at 614-871-4144 for support.

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

If your mini-split is not cooling or blowing cold air, there may be a refrigerant leak. Your mini-split AC needs refrigerant to move heat and keep your residence cool. These leaks must be fixed by a licensed HVAC tech, so reach us at 614-871-4144 for help.

5. Mini-Split is Not Dehumidifying

Much like an air conditioner, a mini-split does a great job at dehumidifying during the summer. However, this could be interrupted by clogs in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very well is if it’s too large. A system that’s too big will cool down a space too rapidly without having time to dehumidify it. Mini-split size is calculated 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 usual smells and what they mean.

Musty, Sour or Mildew

If your mini-split smells musty, sour or like mildew, you might have a mold issue. Have a pro like Air Quality Solutions inspect and flush the condensate drain and drain line, if necessary.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re possibly encountering a refrigerant leak. Another certain hint that you don’t have enough refrigerant is a weak flow of cold air. Contact us at 614-871-4144 for help.

Fish

If your mini-split smells like fish, a couple of things could be wrong. In some instances this smell means there is an electrical problem or that there’s a leak. Nevertheless, reach us at 614-871-4144 for help.

7. Mini-Split Will Not Power On

If your mini-split will not power on, check the remote first. If the batteries are bad, your mini-split won’t turn on. In most experiences, putting in new batteries will fix the problem. If you’re still having trouble, contact us at 614-871-4144.
