What does a CFM of air leakage mean? When an HVAC person or an Indoor Air Quality person talks to you about the air leakage that is occurring in your HVAC system, they refer to something as a “CFM of leakage.”
CFM stands for Cubic Feet per Minute of air leaking. Let’s visualize this. Think of the air it takes to fill up one basketball. Mr. Duct Cleaner likes to refer to it as one “basketball” of air leaking. 1 CFM = amount of air it takes to fill one basketball.
95% of homes in the United States have a significant amount of leaking CFM’s. The air leakage drastically affects utility bills and create unbalanced air, health, and humidity issues. Also, 100 CFM of return leakage can create 10 gallons of water in a 24-hour period (Source: ACHR The News).
Recently, the Mr. Duct Cleaner Denver franchise performed a Clean Seal on their own home that resulted in a HUGE amount of basketballs of air saved. There were 450 CFM (450 basketballs PER MINUTE) that were leaking from the HVAC system ducts. When the Clean Seal and other duct repairs were completed, the leakage was reduced to just 25 CFMs. That is a 95% improvement!
How many basketballs of air is your duct system leaking? It is most likely time to have your duct and HVAC system cleaned. Why not have the Pro Clean Seal experts at Mr. Duct Cleaner clean your system and run an initial leakage report for you? That way you can learn how many basketballs of air are leaking from your system. Once the Clean Seal is complete, you will receive a certificate that reveals how many basketballs of leakage you started with, and how many you now have after the seal is complete.
Remember, this seal is warrantied for 10 years, and the data is sent to Aeroseal. If you sell the property, the certificate remains with the property.
