7 Common Mini-Split Troubles and How to Fix Them

July 12, 2021

Having mini-split installation done is a good way to solve comfort issues in your residence. These systems don’t have to have ductwork to deliver energy-efficient heating and cooling. Similar to any other home comfort system, they can have issues occasionally. Here are seven of the most frequent mini-split problems 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 might be an issue 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 leak. Reach Bell Air Conditioning Inc at 254-307-9572 for support and we’ll get your drain unplugged promptly.

2. Mini-Split is Making Noise

Mini-splits usually don’t generate much noise when they’re operating. But there are two situations where they could create sounds.

  • Popping or clicking: This can be the result of the plastic housing expanding or contracting while the system is on.
  • Swooshing, crackling or gurgling: This can occur if your mini-split goes into defrost mode to prevent itself from freezing up.

You shouldn’t be troubled if you hear these noises because they’re normal. However, if your mini-split keeps switching into defrost mode, it’s a sign that something is wrong, like low refrigerant, a flawed circuit board or malfunctioning sensors. Your Bell Air Conditioning Inc 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, ice on the coils might be to blame. Like we mentioned prior to this, iced-over coils might be the result of insufficient refrigerant, a faulty circuit board or defective sensors. Reach us at 254-307-9572 for assistance.

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

If your mini-split is not cooling or blowing cold air, there could be a refrigerant leak. Your mini-split AC uses refrigerant to shift heat and keep your residence cool. These leaks must be fixed by a licensed HVAC professional, so contact us at 254-307-9572 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 halted by blockages in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very effectivelyis if it’s too big. A system that’s too big will cool down a space too quickly 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 usual 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 pro like Bell Air Conditioning Inc check 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 likely experiencing a refrigerant leak. Another sure sign that you don’t have ample refrigerant is a low concentration of chilled air. Reach us at 254-307-9572 for assistance.

Fish

If your mini-split smells like fish, a couple of things could be wrong. In some instances this smell means there are electrical issues or that there’s a leak. Nevertheless, contact us at 254-307-9572 for assistance.

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 most instances, putting in new batteries will fix the trouble. If you’re still having trouble, contact us at 254-307-9572.
