Your AC Maintenance Tasks

Tap each task to mark it complete. Monthly tasks you can do yourself; quarterly and annual tasks need a professional.

Monthly Checks (DIY)

Takes 10–15 minutes — do this yourself every month

Check the air filter — is it visibly dusty or clogged?

Hold it up to the light. If you can't see light through it, it needs cleaning or replacing.

Visually inspect the indoor unit

Look for dust buildup, water stains, or any cracks on the unit casing.

Check the outdoor unit

Make sure it's not blocked by debris, plants, or objects that restrict airflow.

Listen while the AC runs

Any clicking, grinding, hissing, or rattling sounds that weren't there before?

Check the airflow strength

Hold your hand in front of the unit — airflow should be consistent and strong.

Test the remote control / thermostat

Set a temperature and verify the system responds and reaches it within a reasonable time.

Check for water dripping from the indoor unit

Occasional condensation outside is normal; water dripping inside the room is not.

Quarterly Tasks (Professional)

Book a maintenance visit — AED 120 per unit

Filter replacement or professional deep clean

If you haven't replaced or cleaned filters this quarter, it's overdue.

Coil inspection

The evaporator coil should be clean. Dark deposits or frost indicate a problem.

Condensate drain inspection and flush

A blocked drain causes water leaks and mould growth in the drain tray.

Electrical connections check

Loose connections cause overheating and are a fire risk. This requires a technician.

Performance and temperature test

Verify the unit is reaching the set temperature within an acceptable time frame.

Refrigerant level check

Low refrigerant (not enough cooling despite AC running) suggests a leak that needs diagnosis.

Annual Tasks (Professional)

Once-a-year deeper service for long-term health

Full AC deep cleaning

Full disassembly, steam clean of evaporator coil, fan blade, and drain tray. Recommended yearly.

Coil extraction and chemical clean

For heavily used units or those with visible mould, a full chemical clean is beneficial.

Ductwork inspection

Check for blockages, leaks, or mould growth in the duct system.

Compressor health assessment

A technician checks amp draw and refrigerant pressure to assess compressor condition.

Efficiency audit

Is your system consuming more electricity than last year? Could indicate a developing fault.

Call Us Immediately

Red Flags — Don't Wait

If you notice any of these, stop using the AC and call us. Continuing to run a failing unit can cause much bigger damage.

Water dripping from indoor unit

Turn off AC and call us. Likely a blocked drain or frozen coil.

Burning or chemical smell

Turn off the unit immediately. Could be an electrical fault. Call us or call your building maintenance.

Grinding, banging, or screeching noise

Turn off the unit. Could be a failing motor or compressor. Continuing to run it will worsen the damage.

AC won't turn on at all

Check the circuit breaker first. If power is fine and it still won't start, call us.

AC trips the circuit breaker repeatedly

An electrical fault — don't keep resetting it. Call us or your electrician.

Ice forming on the indoor unit

Turn off cooling, run fan-only mode to defrost. Low refrigerant or blocked airflow is the usual cause. Call us after defrosting.

Room temperature matches outdoor temp despite running AC

The system may have lost refrigerant or the compressor is failing. Call us.

What You Can't Do Yourself

Refrigerant level check

Checking refrigerant levels requires specialist gauges and certification. Low refrigerant indicates a leak that needs professional diagnosis and repair.

Electrical safety inspection

Loose wiring and degraded insulation are fire hazards. A technician checks all electrical connections — something you can't safely do without proper training.

Coil and drain deep clean

A proper quarterly clean requires accessing internal components. DIY cleaning with a spray won't reach the evaporator coil or drain fully.

Early fault detection

Our technicians know what to look for — worn capacitors, weak compressor draw, bearing wear — before they become failures. Early detection saves significant money.
