At thermostat.ae, we provide thermostat sales, installation, maintenance, & smart upgrades across the UAE. Here are the 7 thermostat mistakes costing you money, and how to fix them for good.

Setting the Thermostat Too Low
Many residents set their thermostat to 18°C thinking it will cool faster. It won’t. It only forces your AC to overwork in the UAE heat, increasing electricity consumption.
Better practice:
- Keep the thermostat at 24-26°C for efficiency.
- Use ceiling fans to circulate cool air
- Invest in a smart thermostat for precise control.
Frequent Manual Adjustments
Adjusting your thermostat frequently creates unnecessary load on your AC compressor, leading to higher bills and faster wear on the system.
Tip: Use programmable schedules to maintain consistent temperatures throughout the day instead of constant manual changes.

Ignoring Regular Maintenance
A thermostat with dust-clogged sensors or outdated calibration will misread room temperatures, causing the AC to run longer than necessary.
Maintenance essentials:
- Clean around your thermostat monthly.
- Calibrate annually.
- Book professional servicing through our Service Page to ensure accuracy.

Incorrect Thermostat Placement
Placing your thermostat near windows, direct sunlight, or heat-producing appliances can result in false readings, leading to unnecessary cooling cycles.
Ideal placement:
- Away from direct sunlight.
- In a central location for accurate readings.
- Not near kitchens or drafty areas.
Our team offers professional relocation services for optimal thermostat placement across UAE homes & offices.

Using Old, Non-Smart Thermostats
Traditional thermostats lack efficiency features like learning behavior, humidity control, and remote management, causing energy waste.
Upgrade benefits:
- Lower DEWA bills by up to 20%.
- Monitor and adjust temperatures remotely.
- Receive maintenance alerts automatically.
We stock the latest smart thermostats compatible with UAE AC systems.
Leaving the Thermostat On While Away
Keeping your AC running at normal settings while you’re at work or traveling drains energy without benefit.
What to do:
- Program your thermostat to higher temperatures when away.
- Use “Away” or “Eco” modes on smart thermostats.
- Automate with occupancy sensors to adjust automatically.
Overlooking Firmware Updates on Smart Thermostats
Many residents install smart thermostats but skip firmware updates, missing out on energy-saving optimizations and bug fixes.
Action points:
- Check for firmware updates monthly.
- Enable auto-update if available.
- Contact us if your device shows update errors
