HVAC System cleaning is among the most important cleaning processes that the homeowners or building managers should perform on regular basis. The HVAC systems are usually installed in both commercial and domestic buildings and they circulate air to all parts of the building. In this way, if the HVAC system is not properly cleaned then the contaminated air that will circulate from it to all parts of the building will lead to health issues for the residents, including possible mold or water damage. It has been studied that if a building has access to fresh air, the residents suffer lesser stress and depression related issues as compared to those where access to fresh air is not available. An uncleaned HVAC also tends to malfunction more frequently and severely as compared to a well-managed and cleaned system.
