Common Mini-Split Issues

Lack of Cooling or Heating

  • Could be due to low refrigerant, clogged filters, or a faulty compressor.

Water Leaking from Indoor Unit

  • Often caused by a clogged drain line, a damaged drain pan, or a poor installation angle.

Unresponsive Remote or Thermostat

  • May be due to dead batteries, sensor problems, or communication failure between the remote and indoor unit.

Bad Odors

  • Mold or mildew buildup in filters, drain lines, or coils can cause musty smells.

Icing on Coils or Outdoor Unit

  • Typically a sign of restricted airflow, low refrigerant, or a dirty coil.

Short Cycling

  • When the unit turns on and off frequently, it can indicate a sizing issue, dirty filter, or faulty sensor.

How to Keep Your Mini-Split in Top Shape

A well-maintained mini-split means better comfort, lower energy bills, and fewer breakdowns. Here’s how to keep yours running like new.

Wash Filters Regularly

Wash your air filter every 1–3 months to keep airflow strong and reduce strain on your system

Service Drains

Pouring a vinegar solution directly into the drain pan and verifying it makes its way to where the drain exits the home is a great way to prevent drains from getting clogged up.

Listen For Noises

Listen for Noises - Banging, grinding, or buzzing sounds? That’s your minisplit telling you something’s wrong — don’t ignore it

Monitor Utility Bills

Monitor Energy Bills - Rising utility costs may be a sign your mini-split is losing efficiency. A tune-up can help bring them back down.

Check Setpoints

Ensure your thermostat is set to the right temperature for comfort and efficiency. Ideal temperature setpoint is typically between 70-78 degrees.
