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

1. Mini-Split Leaks or Can’t Drain Water

If your mini-split is dripping water or not draining water, there may be an issue with the condensate drain or drain line. It’s common for a drain line to become clogged with mold, forcing water to back up and spill. Reach All Solutions Heating & Cooling at 971-245-2459 for help and we’ll get your drain unplugged quickly.

2. Mini-Split Makes Constant Noise

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

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

You shouldn’t be alarmed if you hear these noises since they’re typical. However, if your mini-split keeps going into defrost mode, it’s a sign that something is off, such as low refrigerant, a flawed circuit board or malfunctioning sensors. Your All Solutions Heating & Cooling HVAC technician will be able to locate and solve the situation quickly.

3. Mini-Split Isn’t Generating Heat

If your mini-split is not heating or blowing hot air, frozen coils might be the problem. Like we talked about previously, iced-over coils might be the result of insufficient refrigerant, a faulty circuit board or defective sensors. Call us at 971-245-2459 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 needs refrigerant to shift heat and keep your residence cool. These leaks must be resolved by a licensed HVAC tech, so contact us at 971-245-2459 for help.

5. Mini-Split Drainage Is Clogged

Much like an air conditioner, a mini-split does a great job at dehumidifying during the summer. However, this could be halted by clogs in the condensate drain line. Another reason your mini-split air conditioner may not be dehumidifying properly is if it’s too large. A sys
