Why You Shouldn’t Set Your AC to 26°C at Night

In summer, many people lower their AC for quick relief, but setting it too cold can cause health problems, waste energy, and strain the system. Experts suggest aligning your AC setting with the day’s high temperature.

For sleeping, technicians recommend 28°C. It’s warm enough to avoid a night chill but cool enough for restful sleep. It also saves on power usage over the long run.

If 28°C feels too warm, keep it at 26°C but use Sleep Mode. This setting raises the temperature by 1°C after the first hour, and another degree the next hour, ending at 28°C to prevent early-morning cold.

Some complain that 26°C doesn’t cool enough. This can be due to an undersized unit, which struggles even at lower settings. Choosing the right capacity for your room size is crucial.

Other issues include dirty filters, blocked vents, low refrigerant, or compressor faults. Cleaning filters and keeping vents clear can improve performance, while refrigerant or compressor problems require professional attention.

If your AC isn’t cooling at 26°C, check the basics first. If problems persist, call a certified technician to diagnose and fix the issue—keeping your nights both cool and healthy.
