The Colorado State study of twin HVAC systems in schools, one unit and ducts cleaned, the other left as a control, produced results of energy efficiency and utility savings for the cleaned units. Did you know that it also resulted in confirming the secondary hypothesis: Cleaned HVAC systems can provide better indoor air quality to occupants compared to their uncleaned counterparts.
The study pointed out that people spend approximately 90% of their time in urban dwellings. Building environments can have a significant impact on quality of life. A building’s HVAC system effects:
• Thermal comfort
• Respiratory exposure
• Productivity
• Cognitive performance
Dirty HVAC systems are a source of indoor air pollutant accumulation and circulation. HVAC systems:
• Move PMs (also referred to as PM or particle pollution) and other pollutants around
• Become a reservoir for pollution
• Spend energy moving bad actors and pollutants into the air
• Have a concentration of some pollutants that is often 2 to 5 times higher than typical outdoor concentrations!
What is a PM you wonder? According to the EPA, Particulate Matter (PM) is a complex mixture of solid and/or liquid particles suspended in air. These particles can vary in size, shape, and composition. The EPA is especially concerned about particles that are 10 micrometers in diameter or smaller because these particles are inhalable.
The Colorado State study found that there was a significant improvement in indoor air quality from the clean HVAC and duct system. Their research is driving sustainability efforts in the building industry, focusing on integrating indoor air quality management with energy-efficient HVAC systems.
Mr. Duct Cleaner has performed over 16,000 HVAC system and duct cleaning projects and often hears about the lower utility bills as well as the better indoor air quality. There has been an increased interest from allergy-sensitive residents and commercial building occupants regarding regularly scheduled HVAC and duct system cleaning. It is nice to have a scientific study backing up what our satisfied customers are telling us.
