"The furnace took 4 days to get approved( not counting a Sunday) the others were quick but the water heater had to be ordered so without hot water for a week. One ceiling fan was easy but within a year their policy changed and They would not install the one I purchased and had to get a new one approved and then ordered online and took several weeks to get straightened out. Not sure who was at fault, AHS, installer or scheduling with renter. Fee is usually $75 per visit"
