7 Common Mini-Split Problems and How to Repair Them

July 12, 2021

Having mini-split installation done is a great way to solve comfort issues in your residence. These systems don’t have to have ductwork to deliver energy-efficient heating and cooling. Similar to any other home comfort system, they can have issues sometimes. Here are seven of the most typical mini-split issues and how you can resolve 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 situation with the condensate drain or drain line. It’s common for a drain line to be clogged with mold, force water to back up and spill. Reach Farnell Heating & Air Conditioning Inc at 251-471-2674 for assistance and we’ll get your drain unplugged promptly.

2. Mini-Split is Making Noise

Mini-splits normally don’t make much noise when they’re operating. But there are two times where they may produce sounds.

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

You shouldn’t be troubled if you hear these noises as they’re typical. However, if your mini-split keeps switching into defrost mode, it’s a sign that something is up, such as insufficient refrigerant, a faulty circuit board or broken sensors. Your Farnell Heating & Air Conditioning Inc HVAC pro will be able to pinpoint and solve the problem fast.

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 could be the issue. Like we discussed prior to this, iced-over coils could be the effect of insufficient refrigerant, a faulty circuit board or defective sensors. Reach us at 251-471-2674 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 needs refrigerant to shift heat and keep your home cool. These leaks must be fixed by a licensed HVAC pro, so contact us at 251-471-2674 for assistance.

5. Mini-Split is Not Dehumidifying

Similar to an air conditioner, a mini-split does a great job 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 efficientlyis if it’s too large. A system that’s oversized will cool down a space too rapidly without having a moment 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 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 may have a mold issue. Have a professional like Farnell Heating & Air Conditioning Inc inspect 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 sure clue that you don’t have ample refrigerant is a low concentration of cold air. Reach us at 251-471-2674 for support.

Fish

If your mini-split smells like fish, a couple of things could be wrong. In some situations this smell means there are electrical issues or that there’s a leak. Nevertheless, contact us at 251-471-2674 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 run. In the majority of instances, replacing the batteries will solve the situation. If you’re still having trouble, call us at 251-471-2674.
