Before And During Our Stay:

Walk Through With The Air Duct Cleaning Technician

Before commencing the project, the contractor and homeowner will need to perform a walk-through of the entire house. This walk-through/description is to observe all the components of the HVAC system to be cleaned and accessed. It is important that you discus where protective coverings like drop cloths and corner guards should be placed.


Clearing The Work/Cleaning Areas

Start by cleaning the working areas and clearing out the furniture in the duct rooms to ensure they are accessible. Performing these actions will save time and ensure speed in the cleaning process.

Pet Safety

The technicians will be concentrating on their job to ensure quality delivery. Hence, they might be distracted if your pets are at home with you. Sometimes, your pets could cause pandemonium or start running about while playing. These acts could distract the technician and also cause harm to either you, the technician, or your pet.



If you intend to leave your house during the duct cleaning process, give your technician your contact to call you whenever the project has been completed. Your decision might be due to the noise or the dust and pollutants all around. Our advice is that you provide the technician with lockup procedures to help secure your home.
