“Having our office ducts cleaned with the RamAir system was a very positive experience… no dust escaped into the building during the cleaning, and we’ve noticed an extraordinary difference in our air-quality.“

“Having worked in the HVAC industry for many years, I can attest that typically the trunk lines of a duct system hardly have any dust and debris in them, the bulk of it is in the supply lines.
By cleaning the ducts with a negative air truck, you’re pulling the dust and debris from the supply lines into the trunk lines, which makes no sense.
Guarantee Duct Cleaning’s system is far superior.”
