Maintaining Your AC for Longevity
Regular filter cleaning (at least monthly) maximizes cooling performance. Schedule professional servicing every 3–6 months to extend compressor life. Avoid switching off the AC immediately when your room reaches the desired temperature. Maintain room temperature settings between 24 and 26 degrees Celsius for optimal energy efficiency. Ensure the outdoor unit isn’t exposed to direct sunlight.
These five budget-friendly 0.5 PK AC models combine modern features and environmentally conscious refrigerants without breaking the bank. Proper selection and maintenance help you enjoy comfortable indoor temperatures while keeping electricity costs in check.
