Burning smell, sparks, or a breaker tripping twice means switch the power off before anything else.
Nine times out of ten it's the condensate drain pump or a blocked drain line rather than the AC itself. Cassettes sit above the ceiling, so they can't drain by gravity like a wall unit — a small pump lifts the water out. When that pump fails or the line clogs, the drain pan overflows into the ceiling void.
Uneven cooling between rooms, a musty smell when the AC turns on, visible dust around vents, or a noticeable rise in DEWA bills without a change in usage.
With no refrigerant involved, the usual causes are a fouled water coil, a clogged strainer restricting chilled water flow, or a control valve or actuator that has seized shut. All three are serviceable — none require a new unit.
It varies by building. The chilled water supply up to your unit is normally the building's responsibility, while the FCU inside your apartment is usually the occupier's. Check your tenancy or service charge terms, and we're happy to invoice whichever party is responsible.
More often than most systems — typically every 2 to 3 months. They sit at floor level in the dustiest part of the room, often in warehouses or workshops, so their filters and coils load much faster than a ceiling-mounted unit.
Many Dubai buildings require a NOC or advance notice for contractors. We can send our trade licence and insurance documents to your building management ahead of the visit if needed — just let us know when booking.
Most towers built after the mid-2000s use district cooling with fan coil units; older or lower-rise buildings often use individual split units. If you're not sure, tell us the building name and we can usually confirm before the visit.

No. We sheet floors, cover furniture and seal each vent so debris goes into the negative-pressure HEPA vacuum rather than into your room. You're welcome to stay, most customers do.
Yes. We use non-toxic, biodegradable, professional-grade disinfectants approved for occupied spaces. We recommend keeping the room closed for about 30 minutes after fogging, then it's completely safe.
Yes, before and after photos of every duct, sent to your WhatsApp or email on the same day, along with your invoice and service certificate.
Monday to Saturday, 8:30 am to 6:30 pm. Sunday, 10:00 am to 5:00 pm. Call or WhatsApp +971 58 563 0095 and we'll find you a slot, often the same day if you reach us before midday.
No. Alongside AC services we handle water tank cleaning, villa and apartment deep cleaning, office sanitization, sofa and carpet cleaning, painting, marble polishing, tile and grout cleaning, carpentry and general handyman work. One team for the whole property.
Villas usually run larger ducted or multi-split systems with their own water tank and pool, so jobs take longer and cost more. Apartments are often on a building's chilled-water system with smaller, faster jobs and may need building management approval for access.
Yes. We work directly with homeowners and, for tenants, we're happy to coordinate with your landlord or property manager and issue the invoice to whichever party you need.
High occupancy and shower areas add moisture faster than cooling alone can remove it. Balanced fresh air and dedicated dehumidification usually resolve it.
Yes, most gym work is carried out early morning, late night or on quieter days to avoid disrupting members.
Yes, changing room, shower and steam area extract fans and ductwork are part of our fitness centre servicing.
Yes, all filtration, pressure verification and temperature validation work is documented in writing for your compliance records.
Yes, work in treatment and consultation areas is scheduled around your appointment book, including evenings and weekends.

Yes, we regularly schedule maintenance for offices, hotels and restaurants outside operating hours so there is no disruption.
Usually condensation forming on an uninsulated or poorly sealed section of ductwork above the ceiling, which then drips or seeps through the ceiling board. Re-insulating and sealing the affected section is the fix, not just repainting the ceiling.
Topping up gas without finding and fixing the leak first just delays the same problem by a few weeks or months. We always find and repair the leak before recharging, so the fix actually holds.
Yes, we work across Dubai's industrial zones including Al Quoz, Dubai Investment Park, Dubai Industrial City and Jebel Ali.
Yes, every job includes a signed service certificate and before/after photos that you can keep on file for municipality or Civil Defence inspections.
