An attic fan shakes or rattles when it is not getting enough air. To solve this problem, home service pros recommend installing a window at the attic, so that you can open it and allow natural air flow. Please note that the window should be installed at least 30 feet away from the fan.
Old furnace died. SPRINGHOME responded and installed a new furnace the next day. We were completely satisfied with their work and the speed of the service.
