Having mini-split installation done is a good approach to solve comfort issues in your home. 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 problems sometimes. Here are seven of the most common mini-split problems and how you can repair them.

1. Mini-Split Is Leaking or Struggling to Drain Water

If your mini-split is dripping water or not draining water, there might be a problem with the condensate drain or drain line. It’s typical for a drain line to be clogged with mold, forcing water to back up and leak. Contact Northglenn Heating & Air Conditioning at 303-452-4146 for help and we’ll get your drain unclogged promptly.

2. Mini-Split Makes Constant Noise

Mini-splits typically don’t create a lot of noise when they’re operating. But there are a few times where they might make 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 icing over.

You shouldn’t be worried if you hear these noises as they’re typical. However, if your mini-split keeps turning on defrost mode, it’s a clue that something is up, including insufficient refrigerant, a bad circuit board or defective sensors. Your Northglenn Heating & Air Conditioning HVAC pro will be able to locate and correct the problem rapidly.

3. Mini-Split Blows Cold Air in Heating Mode

If your mini-split is not heating or blowing hot air, icy coils may be to blame. Like we mentioned previously, frozen coils may be the consequence of low refrigerant, a bad circuit board or defective sensors. Call us at 303-452-4146 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 house cold. These leaks must be fixed by a licensed HVAC pro, so reach us at 303-452-4146 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 halted by blockages in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very effectively is if it’s too large. A system that’s oversized 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 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 specialist like Northglenn Heating & Air Conditioning check and rinse the condensate drain and drain line, if required.

Vinegar or Chemical Smell

If your mini-split smells like vinegar or has a sweet odor, you’re likely encountering a refrigerant leak. Another sure clue that you don’t have enough refrigerant is a low concentration of cold air. Contact us at 303-452-4146 for assistance

Fish

If your mini-split smells like fish, a few things could be wrong. In some situations this smell means there are electrical issues or there’s a leak. Regardless, reach us at 303-452-4146 for help.

7. Mini-Split Won’t Turn On

If your mini-split will not power on, look at the remote first. If the batteries are bad, your mini-split won’t switch on. In most instances, putting in fresh batteries will fix the situation. If you’re still experiencing trouble, reach us at 303-452-4146.
