7 Common Mini-Split Troubles and How to Fix Them

July 12, 2021

Having mini-split installation done is a fantastic solution for solving comfort problems in your house. These systems don’t need ductwork to provide energy-efficient heating and cooling. Much like any other home comfort system, they can have issues from time to time. Here are seven of the most frequent mini-split troubles 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 situation with the condensate drain or drain line. It’s common for a drain line to be clogged with mold, force water to back up and drip. Contact Thurston Heating & Air Conditioning at 308-624-3485 for assistance and we’ll get your drain unblocked rapidly.

2. Mini-Split is Making Noise

Mini-splits typically don’t make much noise when they’re on. But there are a few times where they might make sounds.

  • Popping or clicking: This can be the result of the plastic housing expanding or contracting while the system is operating.
  • Swooshing, crackling or gurgling: This can happen if your mini-split switches into defrost mode to stop itself from freezing over.

You shouldn’t be alarmed if you hear these noises because they’re expected. However, if your mini-split keeps switching into defrost mode, it’s a hint that something is up, such as low refrigerant, a faulty circuit board or malfunctioning sensors. Your Thurston Heating & Air Conditioning HVAC professional will be able to pinpoint and solve the situation rapidly.

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 issue. Like we discussed previously, frozen coils can be the effect of not enough refrigerant, a failing circuit board or malfunctioning sensors. Call us at 308-624-3485 for help.

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 uses refrigerant to transfer heat and keep your house pleasant. These leaks must be fixed by a licensed HVAC technician, so call us at 308-624-3485 for assistance.

5. Mini-Split is Not Dehumidifying

Like an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this can be halted by blockages in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very well is if it’s oversized. A system that’s too big will cool down a room too rapidly without having a moment 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 get your attention 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 may have a mold issue. Have a pro like Thurston Heating & Air Conditioning examine and clean the condensate drain and drain line, if required.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re possibly experiencing a refrigerant leak. Another sure sign that you don’t have ample refrigerant is a low concentration of cold air. Call us at 308-624-3485 for support.

Fish

If your mini-split smells like fish, a couple of things could be wrong. Sometimes this smell means there is electrical trouble or that there’s a leak. Either way, contact us at 308-624-3485 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 bad, your mini-split won’t switch on. In the majority of situations, replacing the batteries will resolve the issue. If you’re still experiencing trouble, call us at 308-624-3485.
