7 Common Mini-Split Problems and How to Resolve Them

July 12, 2021

Having mini-split installation done is a smart solution for solving comfort troubles in your house. These systems don’t have to have ductwork to provide energy-efficient heating and cooling. Like any other home comfort system, they can have troubles sometimes. Here are seven of the most common mini-split problems 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 typical for a drain line to get clogged with mold, force water to back up and spill. Contact Brandon Heating and Plumbing at 204-728-0180 for support and we’ll get your drain unplugged quickly.

2. Mini-Split is Making Noise

Mini-splits normally don’t create a lot of noise when they’re operating. But there are two situations where they might create 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 happen if your mini-split goes into defrost mode to stop itself from icing up.

You shouldn’t be alarmed if you hear these noises since they’re typical. However, if your mini-split keeps turning on defrost mode, it’s a hint that something is up, like not enough refrigerant, a faulty circuit board or broken sensors. Your Brandon Heating and Plumbing HVAC tech will be able to pinpoint and correct the problem rapidly.

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

If your mini-split is not heating or blowing hot air, icy coils may be to blame. Like we discussed previously, icy coils could be the result of insufficient refrigerant, a faulty circuit board or defective sensors. Reach us at 204-728-0180 for assistance.

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 move heat and keep your residence pleasant. These leaks must be repaired by a licensed HVAC technician, so contact us at 204-728-0180 for support.

5. Mini-Split is Not Dehumidifying

Much like 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 very effectivelyis if it’s oversized. A system that’s too large will cool down an area too fast without having time to dehumidify it. Mini-split size is planned 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 likely have a mold issue. Have a specialist like Brandon Heating and Plumbing inspect and rinse the condensate drain and drain line, if required.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re likely encountering a refrigerant leak. Another certain clue that you don’t have enough refrigerant is a lack of chilled air. Contact us at 204-728-0180 for help.

Fish

If your mini-split smells like fish, the following things things could be wrong. Sometimes this smell means there is electrical trouble or that there’s a leak. Nevertheless, contact us at 204-728-0180 for help.

7. Mini-Split Will Not Power On

If your mini-split will not power on, examine the remote first. If the batteries are dead, your mini-split won’t run. In most situations, replacing the batteries will resolve the problem. If you’re still running into trouble, contact us at 204-728-0180.
