A guy called us with about a week left on his DLP, panicking because his AC had started making a noise he’d been ignoring for months. “It still cools the room, so I figured it was fine.” That’s usually the trap. An AC unit can technically work while quietly developing problems that only show up properly once the warranty’s gone and the bill lands on you instead of the developer.
Why the DLP Deadline Actually Matters for AC
Dubai’s summers put AC systems through more strain than almost anything else in a property, and a lot of installation shortcuts don’t show themselves until a unit’s been running hard for a full year. Refrigerant levels that were slightly off from day one. Ducting that wasn’t sealed properly and is losing efficiency nobody’s noticed because the room still gets cold eventually, just slower and at higher cost.
Once the Defects Liability Period closes, all of that becomes your problem. Not the developer’s. Which is exactly why the week or two before it ends is worth actually using instead of assuming everything’s fine because nothing’s obviously broken.
What to Actually Check Before You Run Out of Time
Start with airflow at every vent in the unit, not just the one in whichever room you happen to be sitting in. Weak airflow in one room while others feel fine usually points to a ducting issue or a balancing problem that won’t fix itself.
Listen to the unit too, properly, not just a passive “does it sound normal.” Grinding, rattling, or a clicking noise on startup are all signs something mechanical isn’t right, and none of those show up if you’re just checking whether cold air comes out.
Check for water around the indoor unit or on the ceiling near it. Condensate lines block more often than people expect, and a slow drip behind a ceiling panel can sit there for a while before it becomes visible, which ties directly into a proper AC inspection services in Dubai covering the whole system rather than just the parts you can see.
Thermostat accuracy is worth a look as well. Set it to 22 and actually measure the room temperature with something separate, because a thermostat reading wrong by a couple of degrees either wastes electricity or means the unit’s working harder than it should to hit a temperature it’s telling you it’s already reached.
Where the Electrical Side Comes In
AC units pull a fair amount of power, and if the circuit feeding it wasn’t sized or wired correctly, you’ll sometimes see breakers tripping under load, especially during peak summer when several units in a building are running at once. An electrical systems inspection covers this side of things, checking whether the wiring feeding your AC units is actually rated for what they draw, not just whether the socket has power.
What a DLP-Timed Inspection Actually Covers
It’s not the same as a routine service. A DLP inspection is specifically about catching things that trace back to the original installation, poor refrigerant charging, undersized ducting, incorrect drainage slope, before the window to have the developer fix them for free closes for good.
If you want the fuller picture of what a DLP inspection covers beyond just AC, our DLP inspection guide walks through the rest of what typically gets checked in that final inspection window.
What Happens If You Miss the Window
Nothing dramatic happens on the day itself. The AC keeps running, life goes on. What changes is who’s paying if something that was actually an installation fault finally shows up six months later. A refrigerant leak that was slow enough to stay hidden during the DLP doesn’t stop being slow once the warranty ends, it just becomes an expense with your name on it instead of the developer’s.
We had a case last summer where a buyer’s unit passed every basic check on the surface, cooled fine, no strange noises, nothing obviously wrong. It was only once we measured actual airflow at each vent that we found one bedroom running noticeably weaker than the rest, traced back to a section of ducting that had been crushed slightly during installation and never fixed. Twenty minutes of measuring caught something that would’ve just meant a permanently warmer bedroom and a higher electricity bill for as long as the buyer owned the place, if the DLP window had closed first.
FAQ’s About AC Checkup Before DLP Expires
How close to DLP expiry should I book an AC check?
Ideally a few weeks out, not the last few days. That leaves enough time to actually get any findings raised with the developer and, hopefully, addressed before the window fully closes.
My AC cools fine, is there really a point checking it?
Cooling fine and running correctly aren’t quite the same thing. A unit can maintain temperature while working harder than it should, drawing more power, or slowly leaking refrigerant, none of which you’d notice just by feeling the air coming out.
Does this apply to central AC as well as split units?
Yes, if anything central systems have more places for an installation issue to hide, given how much more ducting and how many more components are involved compared to a single split unit.
Can Dubshy do this specific DLP-timed AC check?
Yes. Dubshy runs exactly this kind of check as part of a DLP inspection, timed around your specific expiry date rather than a generic service schedule.
Conclusion
An AC that cools the room isn’t the same as an AC that’s actually fine, and the gap between those two only costs you money once the developer’s no longer responsible for it. If your DLP’s closing in, it’s worth getting it looked at properly rather than going on how the air feels. You can book an AC inspection while there’s still time to get anything found actually fixed under warranty.
