7 Common Mini-Split Problems and How to Fix Them

July 12, 2021

Having mini-split installation done is a great approach to solve 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 problems sometimes. Here are seven of the most common mini-split troubles 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 may be a situation with the condensate drain or drain line. It’s common for a drain line to be clogged with mold, force water to back up and leak. Call Four Seasons Air Conditioning and Heating LLC at 361-214-1203 for help and we’ll get your drain unclogged quickly.

2. Mini-Split is Making Noise

Mini-splits usually don’t make much noise when they’re on. But there are a few instances where they might produce sounds.

  • Popping or clicking: This can be the result of the plastic housing expanding or contracting while the system is on.
  • Swooshing, crackling or gurgling: This can occur if your mini-split turns on defrost mode to stop itself from icing up.

You shouldn’t be troubled if you hear these noises because they’re typical. However, if your mini-split keeps switching into defrost mode, it’s a sign that something is wrong, like insufficient refrigerant, a flawed circuit board or broken sensors. Your Four Seasons Air Conditioning and Heating LLC HVAC professional will be able to locate 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, ice on the coils could be the issue. Like we talked about previously, frozen coils can be the result of low refrigerant, a failing circuit board or defective sensors. Call us at 361-214-1203 for help.

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 residence pleasant. These leaks must be repaired by a licensed HVAC pro, so call us at 361-214-1203 for assistance.

5. Mini-Split is Not Dehumidifying

Similar to an air conditioner, a mini-split is efficient at dehumidifying during the summer. However, this might 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 a room 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 get your attention that something is wrong. Here are five of the most typical smells and what they mean.

Musty, Sour or Mildew

If your mini-split smells musty, sour or like mildew, you might have a mold issue. Have a professional like Four Seasons Air Conditioning and Heating LLC inspect 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 possibly encountering a refrigerant leak. Another certain hint that you don’t have enough refrigerant is a lack of cool air. Reach us at 361-214-1203 for help.

Fish

If your mini-split smells like fish, a couple of things could be wrong. Sometimes this smell means there is an electrical problem or that there’s a leak. Nevertheless, reach us at 361-214-1203 for assistance.

7. Mini-Split Will Not Power On

If your mini-split will not power on, examine the remote first. If the batteries are bad, your mini-split won’t turn on. In the majority of instances, replacing the batteries will resolve the problem. If you’re still having trouble, call us at 361-214-1203.
