7 Common Mini-Split Issues and How to Repair Them

July 12, 2021

Having mini-split installation done is a good way to solve comfort problems in your home. These systems don’t require ductwork to give energy-efficient heating and cooling. Much like any other home comfort system, they can have problems from time to time. Here are seven of the most frequent mini-split issues 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 could 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 drip. Call A2Z Air Inc at 561-270-6228 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 on. But there are a few instances where they may produce 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 take place if your mini-split switches into defrost mode to stop itself from freezing over.

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 hint that something is wrong, like not enough refrigerant, a faulty circuit board or defective sensors. Your A2Z Air Inc HVAC professional will be able to pinpoint and solve the situation fast.

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, iced-over coils may be the effect of low refrigerant, a bad circuit board or broken sensors. Contact us at 561-270-6228 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 needs refrigerant to move heat and keep your house comfortable. These leaks must be resolved by a licensed HVAC technician, so contact us at 561-270-6228 for support.

5. Mini-Split is Not Dehumidifying

Like 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 large. A system that’s too large will cool down a room too rapidly without having time 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 grab 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 likely have a mold issue. Have a professional like A2Z Air Inc examine and clean the condensate drain and drain line, if needed.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re possibly encountering a refrigerant leak. Another surefire clue that you don’t have sufficient refrigerant is a low concentration of cool air. Reach us at 561-270-6228 for assistance.

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. Regardless, reach us at 561-270-6228 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 experiences, putting in fresh batteries will solve the trouble. If you’re still experiencing trouble, contact us at 561-270-6228.
