High Temperature Steam Cleaning Service

Pneumonia is rampant and in order to deal with the threat of viruses, we provide specialized air conditioning cleaning services, using high temperature steam up to 120 degrees Celsius to clean the air conditioner.

Unlike traditional flushing cleaning, high-temperature steam cleaning not only has high pressure rinsing, but also uses high-temperature gas to infiltrate and kill bacteria and viruses, which is more effective than traditional high-pressure cleaning in removing dirt and viruses.
