7 Common Mini-Split Troubles and How to Fix Them

July 12, 2021

Having mini-split installation done is a smart way to solve comfort difficulties in your residence. These systems don’t have to have ductwork to give energy-efficient heating and cooling. Similar to any other home comfort system, they can have troubles occasionally. Here are seven of the most typical mini-split issues 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 could be a situation 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 leak. Reach Patterson & Stirling Inc at 814-308-0416 for support and we’ll get your drain unblocked quickly.

2. Mini-Split is Making Noise

Mini-splits usually don’t create a lot of noise when they’re operating. But there are two times where they could produce 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 stop itself from freezing up.

You shouldn’t be worried if you hear these noises since they’re expected. However, if your mini-split keeps switching into defrost mode, it’s a hint that something is off, including low refrigerant, a bad circuit board or broken sensors. Your Patterson & Stirling Inc HVAC professional will be able to find and solve the issue rapidly.

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

If your mini-split is not heating or blowing hot air, icy coils could be to blame. Like we mentioned previously, iced-over coils might be the effect of not enough refrigerant, a bad circuit board or malfunctioning sensors. Contact us at 814-308-0416 for support.

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 move heat and keep your house cold. These leaks must be fixed by a licensed HVAC professional, so contact us at 814-308-0416 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 could be halted by blockages in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying very well is if it’s too big. A system that’s too large will cool down a room too fast without having time 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 tell you 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 likely have a mold issue. Have a professional like Patterson & Stirling Inc inspect 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 likely dealing with a refrigerant leak. Another sure hint that you don’t have sufficient refrigerant is a lack of chilled air. Contact us at 814-308-0416 for assistance.

Fish

If your mini-split smells like fish, a couple of things could be wrong. In some instances this smell means there are electrical issues or that there’s a leak. Regardless, contact us at 814-308-0416 for assistance.

7. Mini-Split Will Not Power On

If your mini-split will not power on, look at the remote first. If the batteries are bad, your mini-split won’t run. In the majority of instances, putting in fresh batteries will solve the issue. If you’re still running into trouble, reach us at 814-308-0416.
