Summer AC Checklist: How to Prepare Your AC for Dubai's Hottest Months
Dubai summers are unforgiving. With temperatures regularly exceeding 45°C and humidity that can make it feel even hotter, your AC isn't just about comfort—it's about safety. The worst time to discover your AC isn't working properly is when you need it most. This pre-summer checklist ensures your system is ready for peak performance when the heat arrives.
Best Time to Prepare: March-April
Schedule your pre-summer AC service before May when demand spikes and technicians become hard to book. By preparing early, you avoid emergency situations during peak heat.
Pre-Summer AC Preparation Checklist
handyman DIY Tasks (Do These Yourself)
Clean or Replace Air Filters
Dirty filters are the #1 cause of AC inefficiency. Remove filters, vacuum off dust, and wash if reusable. Replace disposable filters every 1-3 months during heavy use.
Impact: Up to 15% improved efficiency
Clear Outdoor Unit
Remove any debris, leaves, or items stored around the outdoor unit. Ensure at least 60cm clearance on all sides for proper airflow. Gently hose down the unit to remove dust buildup.
Impact: Prevents overheating and compressor damage
Check Thermostat Operation
Replace batteries if battery-powered. Test by setting temperature 5 degrees below current room temperature—the AC should kick on within a minute. Verify the display is accurate.
Impact: Ensures accurate temperature control
Inspect Vents and Registers
Ensure all supply and return vents are open and unobstructed by furniture, curtains, or rugs. Vacuum vent covers to remove dust.
Impact: Proper airflow throughout your home
Test the System
Run your AC for at least 30 minutes and check: Does it reach set temperature? Any unusual noises? Any water leaks? Any strange smells? Any rooms not cooling properly?
Impact: Early detection of problems
engineering Professional Service Tasks (Schedule a Technician)
Deep Coil Cleaning
Both evaporator (indoor) and condenser (outdoor) coils need professional cleaning. Dirty coils significantly reduce cooling capacity and efficiency.
Refrigerant Level Check
Low refrigerant means reduced cooling and higher energy bills. If levels are low, there's likely a leak that needs repair before topping up.
Drain Line Cleaning
Clogged drain lines cause water leaks and can lead to mold growth. Technicians use special treatments to clear and prevent blockages.
Electrical Connection Inspection
Loose connections and worn contacts can cause system failures or even fire hazards. A technician will check all electrical components and tighten connections.
Overall Performance Test
A professional will measure temperature differential, airflow, and system pressures to ensure everything is operating within specifications.
When to Call a Professional Immediately
During your DIY inspection, watch for these warning signs that require professional attention:
Indicates refrigerant issues or airflow problems
Motor or bearing issues that can worsen quickly
Clogged drain or frozen coils need addressing
Turn off immediately—electrical issue or motor failure
Could be compressor failure or refrigerant leak
May indicate electrical or thermostat issues
Additional Summer Preparation Tips
