7 Common Mini-Split Issues and How to Fix Them

July 12, 2021

Having mini-split installation done is a great solution for solving comfort difficulties in your residence. These systems don’t need ductwork to deliver energy-efficient heating and cooling. Much like any other home comfort system, they can experience issues sometimes. Here are seven of the most frequent mini-split problems 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 might 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 leak. Call Moyer Total Indoor Comfort at 484-646-3363 for assistance and we’ll get your drain unblocked promptly.

2. Mini-Split is Making Noise

Mini-splits usually don’t make much noise when they’re running. But there are a few situations where they may create sounds.

  • Popping or clicking: This can be due to 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 over.

You shouldn’t be alarmed if you hear these noises because they’re typical. However, if your mini-split keeps going into defrost mode, it’s a hint that something is wrong, such as not enough refrigerant, a flawed circuit board or defective sensors. Your Moyer Total Indoor Comfort HVAC technician will be able to find 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 might be the issue. Like we mentioned previously, iced-over coils could be the effect of not enough refrigerant, a bad circuit board or malfunctioning sensors. Call us at 484-646-3363 for support.

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 comfortable. These leaks must be resolved by a licensed HVAC professional, so call us at 484-646-3363 for help.

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 can be halted by blockages in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying properlyis if it’s too large. A system that’s too large will cool down an area too rapidly without having a chance 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 tell you that something is wrong. Here are five of the most typical 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 specialist like Moyer Total Indoor Comfort check 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 likely dealing with a refrigerant leak. Another certain clue that you don’t have ample refrigerant is a low concentration of cool air. Contact us at 484-646-3363 for support.

Fish

If your mini-split smells like fish, the following things things could be wrong. Sometimes this smell means there is an electrical problem or that there’s a leak. Either way, reach us at 484-646-3363 for support.

7. Mini-Split Will Not Power On

If your mini-split will not power on, examine the remote first. If the batteries are out of juice, your mini-split won’t run. In most instances, putting in fresh batteries will fix the trouble. If you’re still experiencing trouble, contact us at 484-646-3363.
