Air Conditioner Cleaning & Sanitizing

We turn on the air conditioner for a long time in the hot summer. Deep cleaning is required after prolonged use of the air conditioner. The weather in Hong Kong is humid. The air conditioner can easily become a breeding ground for bacteria and allergens if there is no regular maintenance and cleaning. It will lead to problems such as mold and air quality that affect human health. Moreover, the dust accumulation will also cause the air conditioner to drop water and not freeze enough, reducing its lifespan. To protect the health of individuals and air conditioners, choose our professional air conditioner cleaning services.
