This is because once you can a particular size motor you just pop fuses or blow circuits. This may limit the total amount of vacuum you can have. On smaller systems this might be less of a concern but on a more substantial system less vacuum can produce some issues.
Having less vacuum can allow dust to escape into the room through the cleaning process. If systems aren't sealed this could cause a drop in the total amount of vacuum on smaller vacuum systems also. More dust may be left in the device due to a lack of a strong vacuum. Vacuum matters and gasoline motors provides more power than an electronic motor running off a 15 amp circuit.

Air duct cleaning has many factors to it, such as for example customer support, and know how. It still comes right down to picking a sincere company with good systems in place. Equipment doesn't run itself but all thing equal I'd pick a residential air duct cleaning company that runs on the gasoline based system because of its cleaning over an electric based cleaning system.
