Having mini-split installation done is an excellent solution for solving comfort difficulties in your house. These systems don’t require ductwork to provide energy-efficient heating and cooling. Much like any other home comfort system, they can have problems occasionally. Here are seven of the most frequent mini-split issues 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 might be a problem with the condensate drain or drain line. It’s expected for a drain line to be clogged with mold, forcing water to back up and spill. Call Northern Comfort Inc at 507-387-6596 for assistance and we’ll get your drain unblocked quickly.

2. Mini-Split Is Making Noise

Mini-splits usually don’t make much noise when they’re operating. But there are a couple of instances where they may produce 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 keep itself from freezing over.

You shouldn’t be worried if you hear these noises because they’re normal. However, if your mini-split keeps turning on defrost mode, it’s a hint that something is up, like low refrigerant, a bad circuit board or broken sensors. Your Northern Comfort Inc HVAC tech will be able to pinpoint and solve the issue rapidly.

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 talked about prior to this, frozen coils can be the result of low refrigerant, a failing circuit board or broken sensors. Contact us at 507-387-6596 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 relies on refrigerant to move heat and keep your house pleasant. These leaks must be repaired by a licensed HVAC tech, so call us at 507-387-6596 for support.

5. Mini-Split Is Not Dehumidifying

Similar to an air conditioner, a mini-split is efficient at dehumidifying during the summer. However, this could be stopped by blockages in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying properly is if it’s too big. A system that’s oversized will cool down an area too quickly without having a chance 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 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 could have a mold issue. Have a pro like Northern Comfort Inc inspect and clean the condensate drain and drain line, if necessary.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re probably experiencing a refrigerant leak. Another surefire hint that you don’t have enough refrigerant is a lack of cold air. Call us at 507-387-6596 for support

Fish

If your mini-split smells like fish, the following things things could be wrong. In some situations this smell means there are electrical issues or there’s a leak. Either way, contact us at 507-387-6596 for assistance.

7. Mini-Split Will Not Power On

If your mini-split will not power on, check the remote first. If the batteries are bad, your mini-split won’t turn on. In many situations, replacing the batteries will resolve the trouble. If you’re still running into trouble, contact us at 507-387-6596.
