Direct answer
Don't sit in a 32°C/90°F unit waiting for a callback. Try the 60-second checklist (remote batteries · breaker reset · drain unblock), then message your host with photo/video so a technician is dispatched within hours, not days.
Report immediately with photo/video if possible. AC is core comfort — fast diagnosis protects sleep and reviews.

In the Riviera Maya, AC isn't a luxury — it's the difference between a tolerable afternoon and a 30°C night you can't sleep through. When a unit stops cooling, the fix is almost always one of five things, in order of how often we see them:
1. Remote/thermostat issue (30% of "broken AC" calls). Batteries dead, wrong mode (Fan instead of Cool), thermostat set above ambient. Check the remote first — if the LCD is blank, batteries.
2. Tripped breaker (25%). Power surges from CFE knock AC circuits off. Open the breaker panel (usually near the front door or kitchen), find the AC breaker (often labeled "Mini-split" or "Aire"), flip it OFF then back ON. If it trips again immediately, stop — that's a wiring issue and needs a technician.
3. Clogged drain line (20%). Mini-split AC units drip condensate through a small tube to the outside. In humid coastal climates, algae build up and clog it; modern units auto-shut-off when the pan fills. Look at the drain tube outside the unit — if no water is dripping, that's the culprit. A 2-minute fix for a tech with a wet/dry vac; impossible for a guest.
4. Refrigerant low (15%). Unit runs but doesn't cool. Air coming out feels lukewarm. This is a tech-only fix; needs gauges and the right refrigerant type (R-410A in most newer units, R-22 in older).
5. Compressor or capacitor failure (10%). Unit clicks but doesn't start, or makes a buzzing sound. Same tech-only category but more serious — often a same-day-replacement part.
What to message your host: - Which room (master bedroom, living room, etc.) - Photo of the thermostat display - Whether you tried the breaker reset - How hot the room currently is (if you have a meter or phone weather)
What a competent host does in response: - Replies within 30–60 minutes during business hours, 2 hours overnight - Sends a technician within 4–6 business hours during weekdays - Offers a portable fan or relocates you if same-day fix isn't possible - Refunds nights affected if AC was down for more than 24 hours
If you're getting "we'll see" responses with no timeline, that's a management red flag — escalate via the booking platform or look for the property's emergency contact in your arrival doc.
Local context
Salt air + humidity demand maintenance — drains, filters, refrigerant, electrical gremlins.
Common mistake
Waiting — heat/humidity escalate guest misery fast.

I've owned and operated rental property across multiple markets — long-term leases, short-term guests, hybrid use. I've run all three models personally and learned what actually protects an asset versus what just looks good on a contract. PlayaStays is built on the operating standards I'd want for my own property in Quintana Roo. If you own here, I'd like to talk.
