7 Common Mini-Split Problems and How to Resolve Them

July 12, 2021

Having mini-split installation done is a fantastic solution for solving comfort issues 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 have issues occasionally. Here are seven of the most frequent mini-split problems 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 might be a situation 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 leak. Call H & H Service Company at 717-220-4502 for help and we’ll get your drain unblocked quickly.

2. Mini-Split is Making Noise

Mini-splits typically don’t generate much noise when they’re operating. But there are a few situations where they might produce sounds.

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

You shouldn’t be alarmed if you hear these noises because they’re typical. However, if your mini-split keeps going into defrost mode, it’s a hint that something is wrong, including insufficient refrigerant, a faulty circuit board or broken sensors. Your H & H Service Company HVAC professional will be able to locate and correct the situation quickly.

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

If your mini-split is not heating or blowing hot air, icy coils might be the problem. Like we discussed previously, icy coils might be the effect of insufficient refrigerant, a faulty circuit board or defective sensors. Contact us at 717-220-4502 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 needs refrigerant to shift heat and keep your house cool. These leaks must be fixed by a licensed HVAC professional, so reach us at 717-220-4502 for assistance.

5. Mini-Split is Not Dehumidifying

Like an air conditioner, a mini-split is efficient 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 effectivelyis if it’s oversized. A system that’s too big will cool down a space too rapidly 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 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 professional like H & H Service Company examine and flush 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 certain sign that you don’t have enough refrigerant is a lack of chilled air. Reach us at 717-220-4502 for assistance.

Fish

If your mini-split smells like fish, a few things could be wrong. In some situations this smell means there is electrical trouble or that there’s a leak. Either way, reach us at 717-220-4502 for help.

7. Mini-Split Will Not Power On

If your mini-split will not power on, check the remote first. If the batteries are out of juice, your mini-split won’t turn on. In many situations, putting in new batteries will solve the situation. If you’re still having trouble, reach us at 717-220-4502.
