7 Common Mini-Split Problems and How to Fix Them

July 12, 2021

Having mini-split installation done is an excellent solution for solving comfort difficulties in your house. These systems don’t need ductwork to deliver energy-efficient heating and cooling. Like any other home comfort system, they can have issues occasionally. Here are seven of the most frequent mini-split issues 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 situation 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 drip. Reach Airmax Long Island Inc at 631-737-5566 for support and we’ll get your drain unclogged rapidly.

2. Mini-Split is Making Noise

Mini-splits normally don’t generate much noise when they’re operating. But there are a couple of situations where they could create sounds.

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

You shouldn’t be troubled if you hear these noises because they’re expected. However, if your mini-split keeps turning on defrost mode, it’s a symptom that something is wrong, such as insufficient refrigerant, a bad circuit board or broken sensors. Your Airmax Long Island Inc HVAC professional will be able to locate and correct the problem quickly.

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

If your mini-split is not heating or blowing hot air, icy coils may be the issue. Like we talked about previously, iced-over coils might be the consequence of low refrigerant, a bad circuit board or malfunctioning sensors. Contact us at 631-737-5566 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 house comfortable. These leaks must be fixed by a licensed HVAC technician, so reach us at 631-737-5566 for support.

5. Mini-Split is Not Dehumidifying

Much like an air conditioner, a mini-split is efficient at dehumidifying during the summer. However, this could be interrupted by clogs in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying properlyis if it’s too big. A system that’s too large will cool down a space too quickly without having a moment 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 usual smells and what they mean.

Musty, Sour or Mildew

If your mini-split smells musty, sour or like mildew, you might have a mold issue. Have a professional like Airmax Long Island Inc 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 experiencing a refrigerant leak. Another certain clue that you don’t have sufficient refrigerant is a low concentration of chilled air. Reach us at 631-737-5566 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 an electrical problem or that there’s a leak. Nevertheless, call us at 631-737-5566 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 bad, your mini-split won’t run. In most instances, replacing the batteries will resolve the issue. If you’re still having trouble, call us at 631-737-5566.
