7 Common Mini-Split Problems and How to Fix Them

July 12, 2021

Having mini-split installation done is an excellent way to solve comfort difficulties in your residence. These systems don’t have to have ductwork to give energy-efficient heating and cooling. Much like any other home comfort system, they can have troubles occasionally. Here are seven of the most typical mini-split troubles 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 might 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 drip. Call Discount Mechanical Heating & Plumbing Services at 907-202-9798 for assistance and we’ll get your drain unblocked quickly.

2. Mini-Split is Making Noise

Mini-splits usually don’t generate much noise when they’re on. But there are a few situations where they may make sounds.

  • Popping or clicking: This can be due to the plastic housing expanding or contracting while the system is operating.
  • Swooshing, crackling or gurgling: This can happen if your mini-split goes into defrost mode to prevent 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 clue that something is off, including insufficient refrigerant, a faulty circuit board or broken sensors. Your Discount Mechanical Heating & Plumbing Services HVAC professional will be able to find and solve the issue fast.

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 the problem. Like we mentioned before, icy coils can be the consequence of not enough refrigerant, a failing circuit board or malfunctioning sensors. Contact us at 907-202-9798 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 home pleasant. These leaks must be fixed by a licensed HVAC professional, so reach us at 907-202-9798 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 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 big. A system that’s too large will cool down a space too quickly without having a moment 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 grab 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 could have a mold issue. Have a professional like Discount Mechanical Heating & Plumbing Services 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 probably dealing with a refrigerant leak. Another sure clue that you don’t have enough refrigerant is a lack of cold air. Reach us at 907-202-9798 for assistance.

Fish

If your mini-split smells like fish, a few things could be wrong. Sometimes this smell means there are electrical issues or that there’s a leak. Regardless, reach us at 907-202-9798 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 dead, your mini-split won’t run. In the majority of instances, putting in new batteries will fix the trouble. If you’re still running into trouble, reach us at 907-202-9798.
