Oakland Mini-Split Service and Repair

Mini-split problems

• Flashing lights or an error code on the head
• Water running down the wall below the unit
• One head cools while another on the same system does not
• A musty smell when the head starts up
• The remote works but the head will not respond

Why heads leak and smell

Every head sends condensate out through a small drain line, and some use a tiny pump. Dust, pet hair and kitchen grease coat the coil and blower wheel, and that film feeds mold and slows the drain. A deep clean of the coil and wheel usually takes care of both the smell and the drip.

Error codes differ by brand. Write down the code or blink pattern and the model number from the sticker under the front cover before you call.

Questions about Mini-Split Service in Oakland

Is mini-split cleaning a DIY job?

You can wash the mesh filters in the sink. The coil and blower wheel need a contractor with a cleaning bag and the right coil cleaner.

Can one outdoor unit run several heads?

Yes, with a multi-zone system. If one head fails while the others work, look at that head's sensor, board or refrigerant lines first.

Do mini-splits heat too?

Most sold today are heat pumps, so they heat and cool. That makes them a common replacement for an old wall furnace.
