Should I adjust my AC thermostat settings as temperatures start dropping in the UAE?

Yes — Raising the Thermostat a Few Degrees Now Cuts DEWA Costs

As outdoor temperatures start easing from peak summer through September and October, raising the thermostat by 2–3 degrees from your usual summer setting typically maintains comfortable indoor temperatures while noticeably reducing AC run-time and the associated DEWA or district cooling costs. Many UAE households keep the same aggressive summer settings year-round out of habit, missing an easy seasonal saving.

Other Adjustments Worth Making This Time of Year

Switching from continuous cooling to a scheduled or timer-based mode for bedrooms overnight becomes more comfortable as outdoor overnight temperatures drop, since the gap between indoor and outdoor temperature needed for comfortable sleep is smaller than during peak summer. Opening windows briefly during cooler early mornings or evenings, once genuinely comfortable outside, can also reduce reliance on AC during those hours specifically.

Why This Is Also a Good Time for a Filter and Vent Check

After months of continuous heavy use through summer, AC filters and vents typically need attention by early autumn regardless of the temperature change itself, and a clogged filter makes the system work harder than necessary even at a higher thermostat setting. Addressing this now means the system runs more efficiently through the milder months ahead.

Finding a Reliable AC Professional in the UAE

You can post the job free on BidMyJob.ae and compare quotes from multiple professionals in your emirate before deciding who to hire for a seasonal filter clean or system check. A professional can also advise on the most efficient thermostat schedule for your specific system type, since ducted and split systems sometimes respond differently to scheduled versus continuous operation.
