After-sales service in dry weather

20 1 1.2. 12 I bought a Gree air conditioner 23556D 1N 1. Before installation, I weighed the outdoor unit, 33.2kg, which is far from the 36kg on the famous brand. After five days of use, it was found that poor heating caused frequent defrosting-but when defrosting, the outdoor unit did not flow out and the weather was dry. Some people say that the temperature difference between the inlet and outlet of the indoor unit (auxiliary heating without electricity) can exceed 20 degrees-but they only measured 16 degrees at home. Jinan Gree also said that the outdoor unit weight error is plus or minus15%-nonsense, which is not only contradictory to Weihai's 5%, but also inconsistent with the convention, obviously cutting corners.
