Before purchasing an aircon unit, consider the room size and required cooling capacity, inverter vs. non-inverter type, energy efficiency rating, installation space, electrical requirements, brand reliability, and warranty coverage.

Cooling capacity depends on room size:

Up to 10 m²: 0.75–1 HP (0.6–0.8 kW)
10–20 m²: 1–1.5 HP (0.8–1.1 kW)
20–30 m²: 1.5–2 HP (1.1–1.5 kW)
30–40 m²: 2–2.5 HP (1.5–1.8 kW)
40–50 m²: 2.5–3 HP (1.8–2.2 kW)

For rooms with high ceilings, many windows, or direct sunlight, consider upgrading to the next higher capacity.

Inverter aircon adjusts compressor speed to maintain steady temperature, making it more energy-efficient and quieter, with higher upfront cost but lower long-term electricity expense.

Non-Inverter aircon turns the compressor on and off, is more affordable upfront, but consumes more electricity and may cause temperature fluctuations.

Set your thermostat to 24°C – 26°C for optimal comfort and energy savings.

Common causes include dirty air filters, low refrigerant (Freon), incorrect unit size for the room, or blocked airflow.

Clean filters every 2–4 weeks to maintain strong cooling performance, better air quality, lower electricity consumption, and longer unit lifespan.

Residential units: every 3–6 months.
Commercial units: every 1–3 months.
Regular servicing prevents major breakdowns and reduces electricity costs.

This may be caused by a clogged drainage line, dirty filters, frozen evaporator coils, or low refrigerant.

Wait 4–6 hours before turning it on to allow refrigerant to settle and prevent compressor damage.

An aircon typically lasts 8–15 years depending on usage and maintenance.

No. Fan Mode only circulates air and does not activate the compressor to lower temperature.

Lack of servicing can result in weak cooling, higher electricity bills, water leaks, bad odor, and possible compressor damage.

Yes. Cleaning removes dirt, dust, and mold (preventive maintenance). Repair fixes damaged or faulty parts (corrective maintenance).

Window type: 45–60 minutes.
Split type cleaning: 1–2 hours.
Major repair: depends on the issue and parts availability.

Bad odor is usually caused by mold or bacteria buildup, dirty filters or drain pan, or clogged drainage system. Professional cleaning and disinfection can resolve this.

Yes. Inverter units use less electricity, maintain steady temperature, operate quietly, and provide long-term savings.

Signs include poor cooling even after cleaning, ice buildup on pipes, hissing sound, or longer cooling time. Refrigerant does not get consumed if levels are low, there is likely a leak.

Yes. Service providers typically offer warranty coverage depending on the type of service performed (cleaning, parts replacement, or repair).
