誰でもできる業務用エアコンクリーニング47 FHYJ140D洗浄動画

This air conditioner is over 20 years old and uses R22 refrigerant. Before starting work, I informed the customer that any malfunctions would not be covered under warranty. This type of air conditioner is rarely seen these days. However, it's a very easy model to disassemble, and I consider it a great piece of equipment.
