7 Common Mini-Split Troubles and How to Resolve Them

Having mini-split installation done is a smart approach to solve comfort issues in your house. These systems don’t need ductwork to deliver energy-efficient heating and cooling. Like any other home comfort system, they can have issues occasionally. Here are seven of the most common mini-split issues and how you can fix them.

1. Mini-Split is Dripping Water or Not Draining Water

If your mini-split is dripping water or not draining water, there could be an issue with the condensate drain or drain line. It’s typical for a drain line to become clogged with mold, force water to back up and spill. Call Abilene Air-Tech Inc at (325) 692-5850 for assistance and we’ll get your drain unplugged promptly.

2. Mini-Split is Making Noise

Mini-splits normally don’t generate much noise when they’re running. But there are a couple of instances where they could 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 keep itself from icing up.

You shouldn’t be alarmed if you hear these noises since they’re normal. However, if your mini-split keeps turning on defrost mode, it’s a clue that something is wrong, like insufficient refrigerant, a bad circuit board or broken sensors. Your Abilene Air-Tech Inc HVAC technician will be able to pinpoint and resolve the situation quickly.

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

If your mini-split is not heating or blowing hot air, frozen coils may be the problem. Like we discussed before, frozen coils may be the effect of not enough refrigerant, a bad circuit board or defective sensors. Call us at (325) 692-5850 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 uses refrigerant to move heat and keep your residence cold. These leaks must be repaired by a licensed HVAC tech, so call us at (325) 692-5850 for support.

5. Mini-Split is Not Dehumidifying

Similar to an air conditioner, a mini-split is effective at dehumidifying during the summer. However, this may be interrupted by mold 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 an area too quickly 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 get 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 may have a mold issue. Have a specialist like Abilene Air-Tech Inc check 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 surefire clue that you don’t have sufficient refrigerant is a weak flow of chilled air. Reach us at (325) 692-5850 for support.

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. Regardless, call us at (325) 692-5850 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 run. In most instances, putting in fresh batteries will resolve the problem. If you’re still running into trouble, reach us at (325) 692-5850.
