7 Common Mini-Split Troubles and How to Repair Them

July 12, 2021

Having mini-split installation done is a smart solution for solving comfort troubles in your home. These systems don’t need ductwork to deliver energy-efficient heating and cooling. Like any other home comfort system, they can experience troubles occasionally. Here are seven of the most common mini-split issues 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 may be a problem with the condensate drain or drain line. It’s common for a drain line to become clogged with mold, force water to back up and spill. Call Air Houston Mechanical LLC at 832-777-1521 for help and we’ll get your drain unplugged rapidly.

2. Mini-Split is Making Noise

Mini-splits typically don’t generate much noise when they’re operating. But there are a few instances where they may 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 take place if your mini-split goes into defrost mode to keep itself from icing over.

You shouldn’t be worried if you hear these noises because they’re expected. However, if your mini-split keeps switching into defrost mode, it’s a symptom that something is up, like low refrigerant, a faulty circuit board or defective sensors. Your Air Houston Mechanical LLC HVAC tech will be able to locate 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 might be to blame. Like we discussed prior to this, iced-over coils can be the consequence of low refrigerant, a failing circuit board or defective sensors. Call us at 832-777-1521 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 transfer heat and keep your home cool. These leaks must be fixed by a licensed HVAC technician, so reach us at 832-777-1521 for assistance.

5. Mini-Split is Not Dehumidifying

Similar to an air conditioner, a mini-split does a great job 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 too large. A system that’s too big will cool down an area too rapidly without having a moment 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 likely have a mold issue. Have a specialist like Air Houston Mechanical LLC check and clean the condensate drain and drain line, if required.

Vinegar

If your mini-split smells like vinegar or has a sweet odor, you’re probably dealing with a refrigerant leak. Another surefire clue that you don’t have sufficient refrigerant is a lack of cool air. Reach us at 832-777-1521 for assistance.

Fish

If your mini-split smells like fish, a couple of things could be wrong. Sometimes this smell means there are electrical issues or that there’s a leak. Either way, call us at 832-777-1521 for assistance.

7. Mini-Split Will Not Power On

If your mini-split will not power on, check the remote first. If the batteries are bad, your mini-split won’t switch on. In most instances, putting in fresh batteries will solve the situation. If you’re still experiencing trouble, reach us at 832-777-1521.
