7 Common Mini-Split Troubles and How to Resolve Them

July 12, 2021

Having mini-split installation done is an excellent solution for solving comfort troubles in your house. These systems don’t have to have ductwork to provide energy-efficient heating and cooling. Much like any other home comfort system, they can run into issues from time to time. Here are seven of the most frequent mini-split troubles and how you can resolve 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 typical for a drain line to get clogged with mold, force water to back up and drip. Contact House of Heating Incorporated at 715-384-3163 for support and we’ll get your drain unclogged rapidly.

2. Mini-Split is Making Noise

Mini-splits normally don’t generate much noise when they’re operating. But there are a couple of instances where they could make sounds.

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

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 clue that something is up, including low refrigerant, a flawed circuit board or malfunctioning sensors. Your House of Heating Incorporated HVAC pro will be able to find and resolve the issue 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 talked about previously, frozen coils might be the effect of not enough refrigerant, a bad circuit board or malfunctioning sensors. Reach us at 715-384-3163 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 transfer heat and keep your house cool. These leaks must be repaired by a licensed HVAC technician, so reach us at 715-384-3163 for help.

5. Mini-Split is Not Dehumidifying

Similar to an air conditioner, a mini-split is efficient at dehumidifying during the summer. However, this may be halted by clogs in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very effectivelyis if it’s too large. A system that’s oversized will cool down an area too quickly 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 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 may have a mold issue. Have a pro like House of Heating Incorporated examine 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 likely experiencing a refrigerant leak. Another surefire hint that you don’t have ample refrigerant is a low concentration of cool air. Reach us at 715-384-3163 for help.

Fish

If your mini-split smells like fish, the following things things could be wrong. In some situations this smell means there is an electrical problem or that there’s a leak. Either way, reach us at 715-384-3163 for support.

7. Mini-Split Will Not Power On

If your mini-split will not power on, look at the remote first. If the batteries are dead, your mini-split won’t run. In the majority of situations, putting in new batteries will resolve the trouble. If you’re still having trouble, contact us at 715-384-3163.
