Having mini-split installation done is an excellent approach to solve comfort difficulties in your home. These systems don’t require ductwork to deliver energy-efficient heating and cooling. Much like any other home comfort system, they can experience troubles sometimes. Here are seven of the most frequent mini-split problems and how you can repair them.

1. Mini-Split Leaks or Can’t Drain Water

If your mini-split is dripping water or not draining water, there may be a situation 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 drip. Contact Lanz Furnace and Fireplace at 608-291-3606 for help and we’ll get your drain unblocked promptly.

2. Mini-Split Is Much Noisier

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

  • Popping or clicking: This can be the result of the plastic housing expanding or contracting while the system is running.
  • Swooshing, crackling or gurgling: This can take place if your mini-split switches into defrost mode to stop itself from icing over.

You shouldn’t be worried if you hear these noises since they’re typical. However, if your mini-split keeps turning on defrost mode, it’s a symptom that something is off, including low refrigerant, a bad circuit board or broken sensors. Your Lanz Furnace and Fireplace HVAC professional will be able to pinpoint and solve the problem quickly.

3. Mini-Split Heating Isn’t Working

If your mini-split is not heating or blowing hot air, icy coils might be the issue. Like we mentioned before, iced-over coils could be the result of not enough refrigerant, a bad circuit board or broken sensors. Reach us at 608-291-3606 for assistance.

4. Mini-Split Cooling Isn’t Working

If your mini-split is not cooling or blowing cold air, there could be a refrigerant leak. Your mini-split AC needs refrigerant to shift heat and keep your home cool. These leaks must be repaired by a licensed HVAC professional, so reach us at 608-291-3606 for help.

5. Mini-Split Drainage Is Clogged

Much like an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this could be stopped by mold in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying properly is if it’s oversized. A system that’s oversized 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 get your attention that something is wrong. Here are five of the most common smells and what they mean.

Mold or Mildew

If your mini-split smells musty, sour or like mildew, you could have a mold issue. Have a specialist like Lanz Furnace and Fireplace inspect and clean the condensate drain and drain line, if needed.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re possibly encountering a refrigerant leak. Another surefire hint that you don’t have ample refrigerant is a weak flow of cool air. Call us at 608-291-3606 for help

Fish

If your mini-split smells like fish, a few things could be wrong. In some instances this smell means there are electrical issues or there’s a leak. Regardless, contact us at 608-291-3606 for support.

7. Mini-Split Isn’t Starting

If your mini-split will not power on, look at the remote first. If the batteries are dead, your mini-split won’t turn on. In most experiences, putting in fresh batteries will resolve the trouble. If you’re still running into trouble, contact us at 608-291-3606.
