In January of 2010, PowerMate® Dolly was there to help contractors to minimize the costs and labor impact with the introduction of the new SEER rated air conditioning units. While the new more energy efficient units had their obvious benefits to users and the environment, the larger, heavier units required a solution to make moving them easier for the installer and mostly, a one person job. The PowerMate® Model LE-1 was there to help keep labor costs to a minimum and eliminate one area of concern making moving and installing the new A/C units a virtual non-issue!
