Yes. We provide 24/7 emergency support for AC failures, duct emergencies, and cooling system breakdowns across the UAE. You can contact us directly by phone for immediate assistance whenever urgent cooling issues occur.
How much does AC repair usually cost?
AC repair costs depend on the issue, AC type, system capacity, and overall condition. Common problems such as no cooling, warm air, airflow issues, leaks, or electrical faults typically fall within a defined range. We always inspect first and confirm the final cost before starting any repair work.
How often should air ducts be cleaned?
In general, air ducts should be cleaned every 3–5 years. However, earlier cleaning is recommended if you have pets, smokers, allergy sufferers, recent renovations, or noticeable dust, odors, or airflow issues. UAE climate conditions often justify more frequent inspections.
How do we choose a reliable duct-cleaning company?
A proper duct-cleaning company should have trained technicians, clear pricing, suitable equipment, and transparent procedures. We recommend choosing a provider that performs inspections, explains the process clearly, and avoids unnecessary or exaggerated claims.
What happens during your duct-cleaning service, and how long does it take?
Our duct-cleaning process begins with a system inspection. We protect surrounding areas, clean the ductwork using professional equipment, remove contaminants, and conduct a final system check. The duration depends on the size of the property and duct condition, but most jobs take a few hours.
How can ducts and HVAC systems be maintained between cleanings?
Between professional cleanings, we recommend replacing or cleaning filters every 1–3 months, keeping vents unblocked, scheduling regular HVAC inspections, and maintaining drain lines and coils. Optional UV solutions can also help reduce bacteria and mold growth.
What are the benefits of regular duct cleaning?
Regular duct cleaning improves indoor air quality, reduces allergens, helps maintain consistent airflow, lowers system strain, and supports better energy efficiency. Clean ducts also contribute to a longer HVAC system lifespan.
My AC is not cooling at all. What could be wrong?
A complete loss of cooling usually indicates low refrigerant levels, compressor failure, or blocked coils. We diagnose the exact cause and perform refrigerant leak repair, system recharge, or compressor service as required.
My AC blows warm air. How do you fix this?
Warm air is commonly caused by low refrigerant, dirty evaporator coils, or thermostat issues. We resolve this by correcting refrigerant levels, cleaning coils, or repairing or recalibrating the thermostat.
Why is airflow weak or inconsistent from my AC?
Weak airflow often results from clogged filters, fan motor problems, or duct blockages. Our solution includes filter replacement, fan motor repair, and duct inspection or cleaning to restore proper airflow.
Why is my AC leaking water?
Water leakage is typically caused by blocked drain lines, frozen coils, or damaged drain pans. We clean the drainage system, defrost coils if needed, and replace damaged components to stop the leak permanently.
Why does my AC make rattling, buzzing, or grinding noises?
Unusual noises usually indicate loose parts, worn motor bearings, or fan imbalance. We inspect the system, secure loose components, and repair or replace faulty parts to prevent further damage.
What should I do if there’s a burning or electrical smell from my AC?
A burning or electrical smell indicates wiring faults, capacitor failure, or overheating components. We recommend turning the system off immediately and contacting us for electrical inspection and repair.
My AC vents smell musty. What causes this?
Musty or unpleasant odors typically result from mold or bacteria growth inside ducts or coils. We perform duct cleaning, coil cleaning, and sanitization to eliminate the source of the odor, not just mask it.
Why does my AC turn on and off frequently?
Frequent cycling, also known as short cycling, is often caused by thermostat issues or refrigerant imbalance. We correct sensor readings, recalibrate thermostats, and check refrigerant levels to stabilize operation.
My electricity bills are high. Can you help reduce them?
Yes. High bills are usually caused by dirty coils, airflow issues, or refrigerant problems. Our maintenance and efficiency checks help restore proper operation and reduce unnecessary energy consumption.
My AC won’t turn on at all. What could be the issue?
If the AC doesn’t start, the cause is often a blown fuse, PCB fault, or motor failure. We carry out electrical diagnostics and repair or replace the faulty component accordingly.
Why is ice forming on my AC coils or pipes?
Ice buildup usually occurs due to refrigerant leaks or restricted airflow. We inspect the coils, repair leaks, improve airflow, and restore proper system balance to prevent icing from returning.
