Ask us anything.

Every 6 months for a home that runs it nightly; every 3 months for pet or allergy homes, bedrooms near a main road, and anything running 12+ hours a day. Dust and humidity here clog a coil about twice as fast as in a dry climate.

Usually same or next day. The no-cool line runs daily until 22:00 — hosts with a guest turning over get priority slots between check-out and check-in.

About 45 minutes per wall-mounted unit, including the temperature check and photos. A deep chemical wash takes 60–90 minutes per unit.

No. Every unit is washed inside a sealed wash bag that drains into a bucket, the floor gets a drop sheet, and we wipe the unit and wall down before the photo.

Every job has an English-speaking lead, and support on LINE and WhatsApp works in English and Thai.

All Bangkok BTS and MRT zones — Sukhumvit, Thonglor, Silom, Sathorn, Ari, Ratchada, On Nut and beyond. Outside the list? Ask — we probably cover it.

By the number of indoor units — 1 to 8. No survey needed to quote, and the price we show is the price you pay for all of them in one visit.

One-time is a single visit with a 30-day guarantee. Year packages bundle 2 or 4 cleans at a 10–25% lower per-visit price, with free gas and drain checks, priority call-outs and a guarantee that runs the whole year.

We refund unused visits, no questions asked. A package is a bundle of visits valid 12 months — not a contract. You can also split payment in two at no cost.

Never. Coil cleaner, wash bags, pressure washer and the photo report are included in every listed price.

Before and after photos of the coil and blower, supply-air temperature before and after, the drain test result, and the gas pressure reading — so you can see the change, not just take our word.

Standard if the unit was cleaned in the last year and just needs its 6-month service. Deep wash if it smells, drips, blows weak, or hasn't been touched in 18+ months — the blower wheel comes out and everything is stripped.

Nine times out of ten it's a dirty coil, not gas. That's why the clean comes first and the gas check is included. If pressure really is low, the system is leaking — we find and quote the leak rather than topping up blindly.

90 days on parts and labour. The ฿590 diagnostic is waived when you go ahead with the repair, and you get a fixed written quote before any work.

Yes — that's what HostCool is built for. Same-day no-cool call-outs in the turnover window, with a dated report you can show the guest or the platform.

Yes — a numbered per-unit log with temperature and current readings, filter schedules and an energy report is standard on commercial programs.

Three or more properties gets 10% off, and bundling with CleanRova cleaning saves another 10%. Larger portfolios are quoted individually — usually better.
