7 Common Mini-Split Troubles and How to Resolve Them

July 12, 2021

Having mini-split installation done is a wise solution for solving comfort difficulties in your house. These systems don’t require ductwork to give energy-efficient heating and cooling. Similar to any other home comfort system, they can run into troubles occasionally. Here are seven of the most common mini-split problems and how you can repair 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 leak. Reach Stieferman Heating Company Inc at 573-203-3908 for support and we’ll get your drain unplugged quickly.

2. Mini-Split is Making Noise

Mini-splits typically don’t make much noise when they’re operating. But there are two instances where they could make 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 prevent itself from icing over.

You shouldn’t be troubled if you hear these noises since they’re expected. However, if your mini-split keeps switching into defrost mode, it’s a symptom that something is wrong, like not enough refrigerant, a flawed circuit board or broken sensors. Your Stieferman Heating Company Inc HVAC technician will be able to pinpoint 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 issue. Like we discussed prior to this, frozen coils can be the effect of insufficient refrigerant, a faulty circuit board or broken sensors. Contact us at 573-203-3908 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 relies on refrigerant to transfer heat and keep your residence comfortable. These leaks must be fixed by a licensed HVAC tech, so contact us at 573-203-3908 for help.

5. Mini-Split is Not Dehumidifying

Similar to an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this may be stopped by blockages in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very efficientlyis if it’s too large. A system that’s too big will cool down an area 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 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 could have a mold issue. Have a professional like Stieferman Heating Company Inc inspect and rinse the condensate drain and drain line, if necessary.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re likely experiencing a refrigerant leak. Another sure hint that you don’t have ample refrigerant is a low concentration of cold air. Reach us at 573-203-3908 for help.

Fish

If your mini-split smells like fish, the following things things could be wrong. In some situations this smell means there are electrical issues or that there’s a leak. Nevertheless, reach us at 573-203-3908 for support.

7. Mini-Split Will Not Power On

If your mini-split will not power on, examine the remote first. If the batteries are bad, your mini-split won’t switch on. In most situations, replacing the batteries will solve the trouble. If you’re still having trouble, contact us at 573-203-3908.
