In the past 10 days, a post on a social platform that said "air conditioners are overcharged for non-cooling repairs" has caused heated discussion. The user reported that the maintenance personnel charged 2,000 yuan on the grounds of "compressor damage", but it was later verified that it was just a clogged filter. Such events alert users to:
1. Choose formal maintenance channels and avoid “copycat” services.
2. Ask the maintenance personnel to produce a fault detection report.
3. Compare multiple quotes to avoid being overcharged.
Summary
Air conditioner not cooling is a common problem in summer, but in most cases it can be solved through simple troubleshooting.
