A ductless mini-split or multi-split system could be an ideal solution for keeping your Bloomington, IL home comfortable. According to the Department of Energy, these systems use 30% less energy than central air conditioners. Look out for these signs that your ductless mini-split system is malfunctioning.

Loud or Unusual Sounds

A feature of ductless mini-split systems is their low noise level. If your outdoor unit or any of the indoor units starts to make a buzzing, grinding, or clanging sound, you’ll need urgent ductless HVAC repairs. The system could have a loose part or a mechanical problem.

Leaking Water

Each indoor unit of a ductless multi-split requires a condensate drain. This drain is part of the conduit, and it leads to the outdoors. A crack or split in the drain or conduit may cause the condensed moisture to leak. If this happens when you’re away from home for a few days, you could return to significant water damage.

Frozen Coil

One or more of the indoor units of a ductless mini-split system may experience a frozen coil. This usually results from dirt buildup on the coil. When the warm air passes over the dirty coil, the refrigerant within the coil can’t effectively absorb the heat energy from the air. The coil keeps getting colder every time the system cycles. Eventually, this causes the condensation on the coil to freeze. Dirty coils can be prevented with a semi-annual tune-up of your mini-split system.

No Cooling

No cooling is a strong indication of a malfunctioning mini-split system. First, check the thermostat. If it’s set to cool and responsive to temperature adjustments, check each unit’s air filter. If the air filters are clean, you’ll need prompt ductless HVAC repairs. A refrigerant leak, compressor failure, or damaged capacitor could be a cause of no cooling.
