Having mini-split installation done is an excellent approach to solve comfort troubles in your home. These systems don’t need ductwork to deliver energy-efficient heating and cooling. Much like any other home comfort system, they can experience issues occasionally. Here are seven of the most common mini-split troubles 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 may be an issue with the condensate drain or drain line. It’s common for a drain line to get clogged with mold, forcing water to back up and spill. Call Air Alliance Team at 636-206-4250 for help and we’ll get your drain unclogged promptly.

2. Mini-Split Is Making Noise

Mini-splits normally don’t generate much noise when they’re operating. But there are a few instances where they may 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 occur if your mini-split switches into defrost mode to prevent itself from icing up.

You shouldn’t be alarmed if you hear these noises since they’re normal. However, if your mini-split keeps going into defrost mode, it’s a sign that something is off, including not enough refrigerant, a faulty circuit board or broken sensors. Your Air Alliance Team HVAC pro will be able to pinpoint and solve the situation quickly.

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 may be the issue. Like we discussed prior to this, icy coils may be the consequence of not enough refrigerant, a failing circuit board or malfunctioning sensors. Contact us at 636-206-4250 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 transfer heat and keep your residence cool. These leaks must be repaired by a licensed HVAC professional, so reach us at 636-206-4250 for support.

5. Mini-Split Is Not Dehumidifying

Much like an air conditioner, a mini-split does a great job at dehumidifying during the summer. However, this might be stopped by mold in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very effectively is if it’s oversized. A system that’s too big will cool down a room too quickly without having a chance 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 tell you 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 Air Alliance Team examine and rinse the condensate drain and drain line, if needed.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re probably encountering a refrigerant leak. Another sure hint that you don’t have enough refrigerant is a weak flow of chilled air. Reach us at 636-206-4250 for support

Fish

If your mini-split smells like fish, a couple of things could be wrong. Sometimes this smell means there are electrical issues or there’s a leak. Nevertheless, reach us at 636-206-4250 for assistance.

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 many situations, putting in new batteries will solve the trouble. If you’re still having trouble, reach us at 636-206-4250.
