7 Common Mini-Split Problems and How to Repair Them

July 12, 2021

Having mini-split installation done is a smart solution for solving comfort troubles in your residence. These systems don’t require ductwork to deliver energy-efficient heating and cooling. Like any other home comfort system, they can run into problems occasionally. Here are seven of the most typical mini-split troubles and how you can fix 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 a problem with the condensate drain or drain line. It’s expected for a drain line to get clogged with mold, force water to back up and spill. Call Bishop Heating & Air Conditioning at 760-784-9034 for assistance and we’ll get your drain unplugged promptly.

2. Mini-Split is Making Noise

Mini-splits normally don’t generate much noise when they’re operating. But there are two instances where they may 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 happen if your mini-split turns on defrost mode to keep itself from icing up.

You shouldn’t be alarmed if you hear these noises since they’re typical. However, if your mini-split keeps going into defrost mode, it’s a sign that something is up, like low refrigerant, a flawed circuit board or malfunctioning sensors. Your Bishop Heating & Air Conditioning HVAC technician will be able to find and solve the issue fast.

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

If your mini-split is not heating or blowing hot air, frozen coils might be the issue. Like we mentioned before, icy coils might be the effect of low refrigerant, a failing circuit board or malfunctioning sensors. Reach us at 760-784-9034 for assistance.

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 uses refrigerant to shift heat and keep your residence pleasant. These leaks must be repaired by a licensed HVAC pro, so reach us at 760-784-9034 for support.

5. Mini-Split is Not Dehumidifying

Similar to an air conditioner, a mini-split is efficient 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 well is if it’s oversized. A system that’s too big will cool down a room too rapidly 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 get 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 pro like Bishop Heating & Air Conditioning check 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 possibly dealing with a refrigerant leak. Another surefire clue that you don’t have sufficient refrigerant is a lack of chilled air. Contact us at 760-784-9034 for support.

Fish

If your mini-split smells like fish, the following things things could be wrong. In some instances this smell means there is electrical trouble or that there’s a leak. Regardless, reach us at 760-784-9034 for assistance.

7. Mini-Split Will Not Power On

If your mini-split will not power on, look at the remote first. If the batteries are dead, your mini-split won’t switch on. In most instances, putting in new batteries will resolve the problem. If you’re still running into trouble, reach us at 760-784-9034.
