7 Common Mini-Split Issues and How to Resolve Them

July 12, 2021

Having mini-split installation done is a wise solution for solving comfort difficulties in your residence. These systems don’t need ductwork to provide energy-efficient heating and cooling. Like any other home comfort system, they can have troubles sometimes. Here are seven of the most common 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 a situation with the condensate drain or drain line. It’s typical for a drain line to be clogged with mold, force water to back up and drip. Contact MPC Heating & Cooling at 308-832-4321 for help and we’ll get your drain unplugged rapidly.

2. Mini-Split is Making Noise

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

  • Popping or clicking: This can be due to the plastic housing expanding or contracting while the system is operating.
  • Swooshing, crackling or gurgling: This can happen if your mini-split goes into defrost mode to keep itself from icing up.

You shouldn’t be alarmed if you hear these noises because they’re normal. However, if your mini-split keeps switching into defrost mode, it’s a hint that something is wrong, including low refrigerant, a faulty circuit board or broken sensors. Your MPC Heating & Cooling HVAC professional will be able to locate and resolve the situation fast.

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

If your mini-split is not heating or blowing hot air, icy coils could be the problem. Like we discussed prior to this, iced-over coils may be the result of low refrigerant, a failing circuit board or broken sensors. Call us at 308-832-4321 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 transfer heat and keep your home cool. These leaks must be resolved by a licensed HVAC pro, so call us at 308-832-4321 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 interrupted by mold in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very effectivelyis if it’s too big. A system that’s oversized will cool down a space too rapidly without having time to dehumidify it. Mini-split size is planned 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 MPC Heating & Cooling inspect and clean the condensate drain and drain line, if required.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re probably dealing with a refrigerant leak. Another sure hint that you don’t have ample refrigerant is a low concentration of cold air. Contact us at 308-832-4321 for support.

Fish

If your mini-split smells like fish, the following things things could be wrong. In some situations this smell means there is electrical trouble or that there’s a leak. Regardless, reach us at 308-832-4321 for help.

7. Mini-Split Will Not Power On

If your mini-split will not power on, examine the remote first. If the batteries are dead, your mini-split won’t run. In many instances, replacing the batteries will solve the trouble. If you’re still running into trouble, reach us at 308-832-4321.
