Having mini-split installation done is a fantastic solution for solving 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 run into troubles from time to time. Here are seven of the most common mini-split issues and how you can repair them.

1. Mini-Split Is Leaking or Struggling to Drain Water

If your mini-split is dripping water or not draining water, there could be a problem with the condensate drain or drain line. It’s typical for a drain line to become clogged with mold, forcing water to back up and spill. Reach Diedrick's Heating and Air Conditioning at 920-833-7967 for support and we’ll get your drain unclogged quickly.

2. Mini-Split Is Much Noisier

Mini-splits normally 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 running.
  • Swooshing, crackling or gurgling: This can occur if your mini-split switches into defrost mode to stop itself from freezing over.

You shouldn’t be alarmed if you hear these noises since they’re normal. However, if your mini-split keeps going into defrost mode, it’s a symptom that something is up, like insufficient refrigerant, a flawed circuit board or defective sensors. Your Diedrick's Heating and Air Conditioning HVAC pro will be able to pinpoint and resolve the problem quickly.

3. Mini-Split Blows Cold Air in Heating Mode

If your mini-split is not heating or blowing hot air, frozen coils could be the issue. Like we mentioned before, frozen coils might be the result of insufficient refrigerant, a faulty circuit board or broken sensors. Reach us at 920-833-7967 for assistance.

4. Mini-Split Cooling Isn’t Working

If your mini-split is not cooling or blowing cold air, there could be a refrigerant leak. Your mini-split AC relies on refrigerant to shift heat and keep your home pleasant. These leaks must be resolved by a licensed HVAC professional, so reach us at 920-833-7967 for support.

5. Mini-Split Drainage Is Clogged

Like an air conditioner, a mini-split is efficient at dehumidifying during the summer. However, this
