Filters should be cleaned every month, and professional maintenance is recommended every 6 months to keep the unit running efficiently and extend its lifespan.

Common reasons include low refrigerant levels, clogged filters, or issues with the compressor. A technician should inspect the unit to diagnose and resolve the issue.

Inverter ACs adjust compressor speed based on room temperature, making them more energy-efficient and quieter than non-inverter models, which turn on and off frequently.

The right AC depends on room size, insulation, and usage. Split units are ideal for single rooms, while central or multi-split systems are better for larger spaces or multiple rooms.

An AC unit typically lasts between 10 to 15 years, depending on usage and regular maintenance. Proper care can extend its life and improve performance.

Signs include frequent breakdowns, weak airflow, unusual noises, higher energy bills, or if the unit is over 10–15 years old. A technician can help assess whether repair or replacement is better.
