Common Mini-Split Problems We Fix
Water Leaking from Indoor Unit
What you see: Dripping water, puddles on floor, water stains on wall
Likely causes:
- Clogged condensate drain line (most common)
- Frozen evaporator coil melting
- Improper installation angle
- Cracked drain pan
⚠️ Don't ignore: Water damage can rot walls and ceilings. Call for same-day service.
Remote Control Not Working
What you see: No response to buttons, display blank, unit won't turn on
Troubleshooting steps:
- Replace batteries (try this first!)
- Check if wall-mounted receiver has power
- Look for obstructions blocking IR sensor
- Try manual control button on unit
If fresh batteries don't fix it, you may need a replacement remote or receiver repair.
Error Codes Flashing
What you see: Blinking lights, error codes on display, beeping sounds
Common codes:
- E0/E1: Sensor malfunction
- E3/E4: High/low pressure (refrigerant issue)
- E5/E6: Outdoor unit problems
- E7: Communication error between units
Error codes require professional diagnosis. We have manufacturer code books and diagnostic tools.
Poor Cooling or Heating Performance
What you see: Weak airflow, not reaching set temperature, runs constantly
Likely causes:
- Dirty filters (check every 2-3 months)
- Low refrigerant from leak
- Compressor wear or failure
- Blocked outdoor coils from debris
Bay Area homes: If your mini-split can't keep up on 90°F+ inland valley days, refrigerant leak is common culprit.
Strange Noises
What you hear: Clicking, buzzing, rattling, or gurgling sounds
What it means:
- Clicking: Relay or contactor issue
- Buzzing: Electrical problem, loose wiring
- Rattling: Loose fan blade or mount
- Gurgling: Refrigerant flow (sometimes normal)
Unusual sounds often signal an issue before complete failure. Early repair prevents bigger problems.
Unit Won't Turn On
What you see: No lights, no response, completely dead
Quick checks:
- Check circuit breaker (both indoor and outdoor)
- Verify power switch hasn't been turned off
- Look for tripped GFCI outlet
- Test remote with fresh batteries
If power is on but unit won't start, could be blown fuse, failed compressor, or control board issue—needs pro diagnosis.
Multi-Zone System Troubleshooting
Multi-head mini-split systems (one outdoor unit serving 2-5 indoor heads) have unique challenges. Here's what to watch for:
One Zone Not Working
If one indoor unit is dead while others work fine, the problem is usually with that specific head unit, its control board, or the refrigerant distribution. We can isolate and repair the affected zone without disturbing the others.
Uneven Cooling Between Zones
Multi-zone systems use branch boxes to split refrigerant. If one room is significantly warmer than others, the branch box may need adjustment, or one zone may have a refrigerant leak. This requires specialized diagnostic equipment.
System Short-Cycling
When too few zones are calling for cooling/heating, the compressor can short-cycle (rapid on/off). This is especially common when you close off bedrooms during the day. Proper system sizing and zone balancing prevents this.
All Zones Down
If every indoor unit stops working simultaneously, the outdoor compressor unit has failed. This could be electrical (blown fuse, contactor), mechanical (seized compressor), or refrigerant-related (low charge triggering safety shutoff).
