Purifiers and Humidifiers

Indoor air pollution can be more hazardous to your health than outdoor air! We can supply and install air purifiers and humidifiers, and we’re certified in duct system design, installation, and cleaning.

Humidifiers are commonly used in homes to relieve the physical discomforts of dry nose, throat, lips, and skin. The moisture they add to dry air also helps alleviate common nuisances brought on by winter heating, such as static electricity, peeling wallpaper, and cracks in paint and furniture.

AMD Mechanical Contractors uses the Rotobrush Duct Cleaning System, which is a portable duct cleaning unit used to clean air ducting and dryer vents.


We use the newest technology to video inspect your air duct system to determine whether it needs to be cleaned.
