In this month's home inspection pictures we see two items. First, we see a VERY old smoke detector. Generally your smoke detectors should be changed every 2-5 years (depending on the manufacturer's recommendation). In the next picture we see deteriorated insulation on the refrigerant line to the AC unit. This can cause you to lose efficiency and cool air (cool air is almost like gold here in FL this time of year!)
