Health Warnings Issued Due to Uncleaned Air Conditioning Systems
In a recent survey made by the Guangdong Indoor Environmental Health association said that a majority of office workers in Shenzhen are breathing in foul air coming from dirty central air conditioning systems. The association also said that more than 90 percent of these air conditioners have never been cleaned since the day it was installed,
Air conditioning systems are the buildings lungs and help provide ventilation, but as the years piles up so does dust and other dirty materials which causes a health threat if the air conditioning system are not cleaned regularly. The survey showed that most of the department stores and offices have not cleaned their systems, while most of them only had the vents washed and cleaned out but the conduits are not touched.
High costs of cleaning are one of the major reasons that businesses are avoiding cleaning their systems. The current market price for cleaning a square meter of air conditioning system is at 25 yuan, and clean a building with a dozen floors could reach 5 to 6 million yuan. Also modern cleaning equipment and professional workers are required to do the cleaning but building manager think that the cost are not worth it. Building managers also find it hard to persuade property owners or its tenants to pay more to help compensate for the costs of cleaning.
