7 Common Mini-Split Issues and How to Resolve Them

July 12, 2021

Having mini-split installation done is a great approach to solve comfort troubles in your home. These systems don’t need ductwork to deliver energy-efficient heating and cooling. Like any other home comfort system, they can have troubles from time to time. Here are seven of the most common 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 an issue 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 spill. Call Keystone Heating & Air Conditioning Co., Inc at 262-358-9468 for assistance and we’ll get your drain unblocked rapidly.

2. Mini-Split is Making Noise

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

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

You shouldn’t be worried if you hear these noises as they’re typical. However, if your mini-split keeps switching into defrost mode, it’s a symptom that something is off, such as low refrigerant, a flawed circuit board or broken sensors. Your Keystone Heating & Air Conditioning Co., Inc HVAC technician will be able to pinpoint and correct the situation quickly.

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 to blame. Like we mentioned previously, frozen coils might be the consequence of insufficient refrigerant, a failing circuit board or malfunctioning sensors. Call us at 262-358-9468 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 home comfortable. These leaks must be fixed by a licensed HVAC professional, so contact us at 262-358-9468 for support.

5. Mini-Split is Not Dehumidifying

Much like an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this can be halted by clogs in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very efficientlyis if it’s oversized. A system that’s too large will cool down a room too fast without having a moment 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 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 could have a mold issue. Have a specialist like Keystone Heating & Air Conditioning Co., Inc examine and flush the condensate drain and drain line, if needed.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re probably dealing with a refrigerant leak. Another sure clue that you don’t have ample refrigerant is a low concentration of chilled air. Call us at 262-358-9468 for assistance.

Fish

If your mini-split smells like fish, the following things things could be wrong. Sometimes this smell means there is an electrical problem or that there’s a leak. Either way, contact us at 262-358-9468 for assistance.

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 the majority of situations, putting in fresh batteries will fix the situation. If you’re still running into trouble, call us at 262-358-9468.
