7 Common Mini-Split Troubles and How to Resolve Them

July 12, 2021

Having mini-split installation done is a great way to solve comfort difficulties in your house. These systems don’t require ductwork to give energy-efficient heating and cooling. Similar to any other home comfort system, they can have issues from time to time. Here are seven of the most common mini-split issues and how you can solve 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 situation with the condensate drain or drain line. It’s typical for a drain line to be clogged with mold, force water to back up and spill. Call Bain Heating & Air Conditioning, Inc at 256-270-1196 for support and we’ll get your drain unblocked quickly.

2. Mini-Split is Making Noise

Mini-splits usually don’t generate much noise when they’re operating. But there are a few 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 operating.
  • Swooshing, crackling or gurgling: This can occur if your mini-split goes into defrost mode to stop itself from freezing up.

You shouldn’t be alarmed if you hear these noises because they’re expected. However, if your mini-split keeps going into defrost mode, it’s a sign that something is off, including insufficient refrigerant, a faulty circuit board or broken sensors. Your Bain Heating & Air Conditioning, Inc HVAC pro will be able to locate and solve 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 the problem. Like we talked about previously, icy coils might be the result of insufficient refrigerant, a faulty circuit board or malfunctioning sensors. Contact us at 256-270-1196 for support.

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

If your mini-split is not cooling or blowing cold air, there may be a refrigerant leak. Your mini-split AC needs refrigerant to shift heat and keep your home cool. These leaks must be resolved by a licensed HVAC pro, so reach us at 256-270-1196 for assistance.

5. Mini-Split is Not Dehumidifying

Like an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this could be halted by clogs in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very well is if it’s oversized. A system that’s oversized will cool down a room too fast without having a moment 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 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 professional like Bain Heating & Air Conditioning, Inc 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 likely dealing with a refrigerant leak. Another certain clue that you don’t have enough refrigerant is a low concentration of chilled air. Call us at 256-270-1196 for assistance.

Fish

If your mini-split smells like fish, a couple of things could be wrong. In some instances this smell means there is electrical trouble or that there’s a leak. Either way, call us at 256-270-1196 for support.

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 the majority of experiences, putting in fresh batteries will solve the issue. If you’re still having trouble, reach us at 256-270-1196.
