Having mini-split installation done is an excellent solution for solving comfort troubles in your residence. These systems don’t have to have 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 frequent mini-split problems and how you can fix 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 a problem with the condensate drain or drain line. It’s common for a drain line to be clogged with mold, forcing water to back up and spill. Contact Lanz Furnace and Fireplace at 608-291-3606 for support and we’ll get your drain unclogged rapidly.

2. Mini-Split Is Making Noise

Mini-splits typically don’t generate much noise when they’re running. But there are a couple of instances where they might produce sounds.

  • Popping or clicking: This can be the result of the plastic housing expanding or contracting while the system is on.
  • Swooshing, crackling or gurgling: This can happen if your mini-split turns on defrost mode to stop itself from freezing over.

You shouldn’t be alarmed if you hear these noises since they’re expected. However, if your mini-split keeps switching into defrost mode, it’s a sign that something is up, including not enough refrigerant, a flawed circuit board or broken sensors. Your Lanz Furnace and Fireplace HVAC tech will be able to find and correct the problem fast.

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

If your mini-split is not heating or blowing hot air, frozen coils might be to blame. Like we discussed previously, frozen coils could be the result of not enough refrigerant, a bad circuit board or broken sensors. Call us at 608-291-3606 for support.

4. Mini-Split Is Not Cooling or Blowing Cold Air

If your mini-split is not cooling or blowing cold air, there could be a refrigerant leak. Your mini-split AC uses refrigerant to shift heat and keep your residence cold. These leaks must be fixed by a licensed HVAC pro, so call us at 608-291-3606 for help.

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 may 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 too big will cool down a space too fast without having time 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 common smells and what they mean.

Musty, Sour or Mildew

If your mini-split smells musty, sour or like mildew, you likely have a mold issue. Have a specialist like Lanz Furnace and Fireplace examine and flush the condensate drain and drain line, if required.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re possibly dealing with a refrigerant leak. Another certain clue that you don’t have sufficient refrigerant is a lack of cold 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 is electrical trouble or there’s a leak. Regardless, call us at 608-291-3606 for assistance.

7. Mini-Split Will Not Power On

If your mini-split will not power on, look at the remote first. If the batteries are out of juice, your mini-split won’t turn on. In most instances, replacing the batteries will fix the situation. If you’re still having trouble, contact us at 608-291-3606.
