The Top Benefits of HVAC Cleaning
Why should you have your HVAC system regularly cleaned? The simple answer is obvious: because over time they become dirty and they have the potential to contain very large deposits of dust and debris.
According to the U.S. Department of Energy, 25 to 40% of the electricity used for cooling or heating is wasted. Dust particles in the cooling and heating system cause it to over work and results in a shortened life of your system. Even though filters are used, the cooling and heating system still gets dirty through regular day to day use. When an HVAC system is professionally cleaned, the system doesn’t have to work as hard to maintain the temperature you desire. This means that less energy is used, resulting in better cost-effectiveness.
Indoor Air Quality
Indoor air quality is one concern that building managers and building inhabitants have when they decide to look into a HVAC system. Through normal occupation in a building, we produce a large amount of contaminants and air pollutants, such as dust, dander, and chemicals. These contaminants are sucked into the HVAC system and then re-circulated as much as 7 times per day. As time goes on, this re-circulation causes a build-up of contaminants in the duct work.
While a contaminated HVAC system doesn"t necessarily mean unhealthy air, the situation may be contributing to larger health issues or harboring contaminants that could cause serious problems for people with respiratory health conditions, autoimmune disorders or some environmental allergies.
An Overview of the Process
During cleaning, the whole HVAC system is placed under constant negative pressure (vacuum) to prevent the spread of debris and contaminants.
This continuous negative pressure allows micro particles to be removed from the entire system as they become airborne; ensuring that these micro particles are not reintroduced into the living space when the system is turned on after cleaning.
This negative pressure also assists in extracting the loose particles, which are then collected, contained and removed from your house.
It is common for HVAC system components to collect significant amounts of debris and particulate while construction is happening in a building. The North American Duct Cleaning Association highly recommends that all newly installed HVAC systems or HVAC systems undergoing renovation be thoroughly cleaned, and protected before the system is turned on.
