7 Common Mini-Split Issues and How to Fix Them

July 12, 2021

Having mini-split installation done is a wise way to solve comfort difficulties in your house. These systems don’t require ductwork to deliver energy-efficient heating and cooling. Much like any other home comfort system, they can have problems sometimes. 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 could 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 leak. Contact Cytech Heating & Cooling L.C. at 956-630-3522 for support and we’ll get your drain unblocked promptly.

2. Mini-Split is Making Noise

Mini-splits typically don’t create a lot of noise when they’re on. But there are two times where they might produce sounds.

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

You shouldn’t be troubled if you hear these noises because they’re normal. However, if your mini-split keeps going into defrost mode, it’s a symptom that something is wrong, like not enough refrigerant, a flawed circuit board or defective sensors. Your Cytech Heating & Cooling L.C. 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 talked about prior to this, icy coils could be the consequence of not enough refrigerant, a faulty circuit board or broken sensors. Call us at 956-630-3522 for help.

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 relies on refrigerant to shift heat and keep your home cold. These leaks must be repaired by a licensed HVAC professional, so reach us at 956-630-3522 for assistance.

5. Mini-Split is Not Dehumidifying

Similar to an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this could be stopped by blockages in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying properlyis if it’s oversized. A system that’s too large will cool down a space too fast without having time 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 tell you 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 professional like Cytech Heating & Cooling L.C. examine and rinse 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 surefire hint that you don’t have enough refrigerant is a weak flow of cool air. Contact us at 956-630-3522 for assistance.

Fish

If your mini-split smells like fish, a few things could be wrong. In some instances this smell means there are electrical issues or that there’s a leak. Either way, reach us at 956-630-3522 for support.

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 experiences, putting in fresh batteries will fix the trouble. If you’re still running into trouble, call us at 956-630-3522.
