An integrated apparatus for carpet cleaning, pressure washing, air duct cleaning and inspection, portable welding, moisture abatement and other building maintenance and repair services, in which a gas engine mounts to a frame and has a drive shaft that extends from the gas engine. A blower, an air compressor, an electric generator, and a water pump also mount to the frame, with the water pump for connecting to a supply of water. A flex coupler connects the drive shaft of the gas engine to the blower. Furthermore, endless belts connect the drive shaft of the gas engine to the air compressor, the electric generator, and the water pump. The gas engine drives the blower, the air compressor, the electric generator, and the water pump, for selective configuration and use for carpet cleaning, pressure washing, air duct cleaning and inspection, portable welding, moisture abatement and other building maintenance and repair services. An air mover with integral dolly communicates high velocity air for moisture abatement or duct-cleaning purposes. A video air tool provides imaging of duct cleaning by pressure attachments.
