7 Common Mini-Split Issues and How to Resolve Them

July 12, 2021

Having mini-split installation done is an excellent way to solve comfort difficulties in your house. These systems don’t have to have ductwork to deliver energy-efficient heating and cooling. Much like any other home comfort system, they can experience problems from time to time. Here are seven of the most typical mini-split troubles and how you can solve 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 get clogged with mold, force water to back up and spill. Contact Cool Air Solutions at 951-299-9853 for assistance and we’ll get your drain unblocked promptly.

2. Mini-Split is Making Noise

Mini-splits normally don’t make much noise when they’re running. But there are a couple of situations where they may 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 take place if your mini-split goes into defrost mode to prevent itself from freezing up.

You shouldn’t be troubled if you hear these noises as they’re expected. However, if your mini-split keeps switching into defrost mode, it’s a clue that something is off, such as insufficient refrigerant, a flawed circuit board or defective sensors. Your Cool Air Solutions HVAC pro will be able to find and resolve the issue rapidly.

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

If your mini-split is not heating or blowing hot air, ice on the coils may be the problem. Like we talked about previously, frozen coils might be the effect of insufficient refrigerant, a faulty circuit board or broken sensors. Reach us at 951-299-9853 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 shift heat and keep your residence cool. These leaks must be fixed by a licensed HVAC pro, so reach us at 951-299-9853 for support.

5. Mini-Split is Not Dehumidifying

Like an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this might be stopped by clogs 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 fast without having a chance to dehumidify it. Mini-split size is based 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 common 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 Cool Air Solutions inspect 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 dealing with a refrigerant leak. Another surefire hint that you don’t have enough refrigerant is a weak flow of cold air. Call us at 951-299-9853 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 electrical trouble or that there’s a leak. Either way, contact us at 951-299-9853 for support.

7. Mini-Split Will Not Power On

If your mini-split will not power on, check the remote first. If the batteries are dead, your mini-split won’t run. In many instances, putting in fresh batteries will resolve the trouble. If you’re still experiencing trouble, call us at 951-299-9853.
