How about Hitachi home central air conditioning? Tell me about used ones, thank you!

? Buying Hitachi central air conditioning is a pit, and after-sales is a problem. My home was renovated in April last year, and I bought more than 20,000 Hitachi central air conditioners in Wuhan Easyhome Air Conditioning Store. I moved in in April this year and used it in summer. Downstairs reflects water seepage on the wall, and my wallpaper is moldy. After inspection by the air conditioning company, the condensate pipe was improperly installed, causing water leakage, and the air conditioning company took full responsibility. However, on the issue of compensation, the air-conditioning company said that users should bear certain responsibilities, and the compensation is only responsible for recognizing half. I am speechless. I'm still responsible for buying air conditioners. I bought a big-name air conditioner, which caused some troubles and made me feel guilty. So when I buy an air conditioner, I must buy an air conditioner with good after-sales and good reputation. Hitachi is really unreliable.
