Everything your aircon needs, in one place
One team of technicians, from the yearly clean to a new installation and a unit that has stopped cooling.
Cleaning & blower-wheel deep clean
PROCARE is a 7-step clean of both coils with a pressure washer. PROCARE PLUS is 9 steps and adds a deep clean of the blower wheel.
- Filter and drain tray cleaned
- Antibacterial treatment
- Sheeted down and cleared up
New installation
Mounting point, pipe run and materials confirmed with you first. Anything beyond standard is quoted before it happens.
- Site checked before fitting
- Tidy pipe run, tested on handover
- Installation guaranteed
Diagnostics & repair
Refrigerant, wiring and compressor checked, then the cause and the cost — before you commit to a repair.
- Cause found before a quote
- No topping up a leaking system
- Repair is your call

How the price works, and what it covers
The three things customers ask most before they book.
Pricing is per unit and by type, not by BTU — every wall-mounted unit costs the same whatever its size. Ceiling cassette, suspended, floor-standing and ducted units are priced separately because they take longer to strip down and clean.
If you do not yet know what is wrong, start with the inspection. The technician measures refrigerant, checks the wiring and the compressor, and tells you the cause and the cost. What happens next is your decision.
Every job starts with a look at the actual site. If it turns out larger than what you booked, you are quoted first and you decide — nothing is added on site without telling you.
Both coils cleaned
Pressure-washed, with the filter and drain tray.
Antibacterial treatment
Fewer germs blown out with the cool air.
Cleared up before leaving
Sheeting down, and a test run with you.
A clear price first
Extra work needs your yes before it starts.
How many BTU does your room need?
Set the room size, pick how hard it is to cool, and get the unit size that fits plus a rough monthly bill.
An undersized unit runs flat out and costs more than you expect; an oversized one short-cycles and leaves the room damp. Matching the unit to the room is the single biggest saving available.
Estimated at 8 hours a day, ฿4.4 per unit, and a compressor running 60% of the time. Your actual bill depends on the set temperature, the room's insulation and the model.

Asked before booking
If the answer you need is not here, message us on LINE or call.
Twice a year suits most homes. Units that run most of the day, sit beside a main road, or share the house with pets are better cleaned every four months. The signs it is due: weaker airflow, a smell when it starts, or water dripping from the indoor unit.
Bangkok and its surrounding provinces: Bangkok, Nonthaburi, Pathum Thani, Samut Prakan and Nakhon Pathom. Each job goes to a technician based near your address. If you are not sure you are covered, ask on LINE or call first.
No. The price follows the type of unit: every wall-mounted unit costs the same at any BTU. Ceiling cassette, suspended, floor-standing and ducted units each have their own price because they are built differently and take longer to strip down.
PROCARE is 7 steps and PROCARE PLUS is 9. Both clean the indoor coil, pressure-wash the outdoor coil, clean the front panel, cover and filter, apply an antibacterial treatment and test the unit before handover. PROCARE PLUS adds a deep clean of the blower wheel, where dust, mould and musty smells build up, and takes the outdoor unit's cover off to reach inside it. PROCARE carries a 30-day workmanship guarantee and PROCARE PLUS 45 days. If the unit still smells musty or blows weakly after a normal clean, choose PROCARE PLUS.
The unit has to be working before it can be cleaned. If it is not running or something is wrong, book the inspection instead. If you booked a clean and the technician finds it cannot be done, you pay only the 300-baht travel fee and can reschedule within 30 days once the unit is ready, or have it inspected for a repair quote.
Three ways: a credit card from any bank, PromptPay, or paying after the job once the technician has finished. Pay-after is for bills under 2,000 baht, one job at a time, once any earlier pay-after job is closed. You choose when you book on LINE or in the app.
Not always. A unit can stop cooling because the coil is blocked with dust, the compressor is not running, there is an electrical fault, or the refrigerant is leaking — and topping up a leaking system only buys a few months. Book the inspection first: the technician finds the cause and quotes the repair before doing it.
It is an estimate from room size and use, which is enough to narrow down a unit size. It does not yet account for ceiling height, which way the room faces, how many people are in it, or how well the walls are insulated. For an actual installation the technician surveys the site and confirms the size before anything is ordered.
Clear the space under the indoor unit and around the outdoor unit so the technician can reach both, and have a water point and a power socket nearby. The technician sheets down the area and clears it again before leaving.
