"Anton was incredibly patient working with me to find a time that worked with my schedule to come clean our ducting before we moved in. We bought a 75 year old house and it was clear from how quickly the furnace filter became black our house needed it. He was incredibly professional and worked quickly and efficiently. It made a noticeable difference in both how long our furnace filters are lasting and the air quality in the house. Would highly recommend this service to anyone whose house may be a little older or just well lived in with pets, kids, etc. "

Our Comany uses the most advanced H.E.P.A (High Efficiency Particulate Air) Filtered Air Duct Cleaning System available. It is designed and manufactured by Nikro Industries, one of the leading manifactureres of H.E.P.A filtered vacuum equipment in the United States. All of our equipment is manufactured to meet or exceed OSHA, EPA, and NADCA Standards for cleaning the air of nuisance dusts. Our powerful H.E.P.A Filtered Vacuum System will first be connected to your air duct near your furnace. Various tools will then be used to dislodge the contaminants and debris in your air ducts. The powerful vacuum will then pull the contaminants out of the ducts and through the filtration system, returning clean air back into your home. Once your system is cleaned, all access holes are resealed, returning your air duct system to original clean condition.
