Top 10 General AC problems and how to fix them
Easy solution for a cooler, more comfortable home
In the extreme heat of Dubai, a functioning air conditioner is not just a luxury—it is a requirement. But like any machine, your AC can run into problems. At Clean Now, experts in AC repair in Dubai, we’ve listed the most common AC issues you may face and how to fix them quickly, so you can stay cool and stress-free.
1. AC Not Turning On
When AC does not have power, it is often caused by simple electrical problems, thermostat errors, or even an unseen switch. This is one of the most common calls we get in Dubai.
- Check if the thermostat batteries are dead
- Make sure the thermostat is set to “Cool.”
- Inspect your home’s circuit breaker.
2. AC Blowing Warm Air
Nothing’s more frustrating than warm air coming from your AC in peak summer. This usually means a setting problem or something more serious, such as cold leakage.
- Confirm that the thermostat is on "cool"; do not put it on "fan" or "heat."
- Change a dirty or closed air filter
- Check if the outdoor condenser unit is working
3. Weak or No Airflow
If the airflow is weak or abnormal in separate rooms, this dirt can be due to a buildup, blocked ventilation, or ducts, affecting regular cooling performance overall.
- Clean or update the air filter
- Open all supply vents and check for blockages
- Inspect ducts for any visible damage or air leaks
4. Strange noise from the device
It seems unusual that fantastic, beating, or buzzing is not normal. They could mean loose parts, fan issues, or even internal motor failure.
- Close the device and inspect for loose screws or panels
- Remove any debris from the external fan leaves
- Rattling may indicate that parts have come loose
5. Water Leaking from AC
Water leaks can cause damage to the floor and walls, and even cause mold. This problem usually comes from a stuffed drain line or a rusty drain pan.
- Turn off your AC immediately
- Use a wet/dry vacuum to unclog the drain line
6. Bad Odors When AC Runs
If AC has musty or combustion smells, it may be caused by mold growth, dirty filters, or electrical defects inside the device.
- Change the old or molded air filter
- Clean the evaporation coil and the drainage pan
7. The thermostat does not respond
A reduced thermostat can cause inconsistent temperatures and poor AC control. Often this is a battery problem, but sometimes the device itself fails.
- Replace the batteries in the thermostat
- Reset the thermostat to factory settings
- Make sure it's placed away from heat sources
8. Frozen Evaporator Coils
If your alternating current stops cooling and you notice ice on the device, the coil can be frozen due to airflow problems or lower levels.
- Close the device and let it melt
- Replace dirty filters to restore airflow
- Don’t run the AC until the coils are defrosted
9. AC Short Cycling
Short cycling is when the AC frequently turns on and off without completing full cooling cycles. This puts extra stress on the system and increases bills.
- Clean or replace clogged filters
- Check that the thermostat isn’t too close to a heat source
- Make sure refrigerant levels are correct
10. High Electricity Bills
A sudden rise in energy costs often points to an inefficient or overworked AC system. Poor maintenance is usually the root cause.
- An AC setting to restore efficiency
- Clean filter, coil, and regular valves
- Seals and windows to prevent cold air loss
