Repair & Not-Cooling
Not cold, dripping, tripping the breaker or flashing an error? A certified technician diagnoses it on the same visit and quotes the fix in writing before touching anything.
Noticing any of these?
You don't need to diagnose it — that's our job. Send a photo or a short video on LINE or WhatsApp and a technician will tell you what you're dealing with before you book.
- Runs but never gets cold, or the compressor won't start
- Water leaking from the indoor unit or outdoor pipe
- Loud rattling, grinding or a fan that won't spin
- Trips the breaker or turns itself off
- Error code flashing on the display or remote

How much do common repairs cost?+
Capacitor ฿1,500–2,500, indoor fan motor ฿2,500–4,500, PCB board ฿3,500–6,000 including parts and labour. Compressors are quoted per unit — sometimes replacement makes more sense, and we'll say so.
Is it worth repairing an old unit?+
If it's under 8 years old, usually yes. Above that, a compressor or board failure often costs half a new inverter unit that will halve the power bill — we'll give you both numbers and let you decide.
Can you come today?+
Same-day slots are held daily until 22:00 for no-cool calls. Hosts with a guest in the property get priority.
