7 Common Mini-Split Troubles and How to Resolve Them

July 12, 2021

Having mini-split installation done is a fantastic approach to solve comfort problems in your house. These systems don’t need ductwork to provide energy-efficient heating and cooling. Much like any other home comfort system, they can experience troubles from time to time. Here are seven of the most typical mini-split troubles 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 situation with the condensate drain or drain line. It’s expected for a drain line to become clogged with mold, force water to back up and drip. Call Premium Air Services LLC at 713-364-9957 for help and we’ll get your drain unplugged rapidly.

2. Mini-Split is Making Noise

Mini-splits typically don’t create a lot of noise when they’re running. But there are two times where they could make sounds.

  • Popping or clicking: This can be due to the plastic housing expanding or contracting while the system is on.
  • Swooshing, crackling or gurgling: This can happen if your mini-split goes into defrost mode to keep itself from icing up.

You shouldn’t be worried if you hear these noises since they’re expected. However, if your mini-split keeps turning on defrost mode, it’s a clue that something is off, including not enough refrigerant, a faulty circuit board or defective sensors. Your Premium Air Services LLC HVAC pro will be able to locate and correct the situation 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 discussed previously, frozen coils can be the effect of low refrigerant, a failing circuit board or broken sensors. Reach us at 713-364-9957 for help.

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

If your mini-split is not cooling or blowing cold air, there might be a refrigerant leak. Your mini-split AC relies on refrigerant to transfer heat and keep your residence cool. These leaks must be repaired by a licensed HVAC pro, so reach us at 713-364-9957 for assistance.

5. Mini-Split is Not Dehumidifying

Much like an air conditioner, a mini-split is efficient at dehumidifying during the summer. However, this might be stopped by mold in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very efficientlyis if it’s too big. A system that’s too big will cool down an area 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 get 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 could have a mold issue. Have a specialist like Premium Air Services LLC check 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 experiencing a refrigerant leak. Another sure sign that you don’t have ample refrigerant is a lack of cool air. Contact us at 713-364-9957 for help.

Fish

If your mini-split smells like fish, the following things things could be wrong. In some instances this smell means there is an electrical problem or that there’s a leak. Nevertheless, contact us at 713-364-9957 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 dead, your mini-split won’t run. In many experiences, replacing the batteries will fix the situation. If you’re still running into trouble, reach us at 713-364-9957.
