the alarm thing on my ceiling upstair went off, what should I do? I mean, there is not a silence button, right now I got the battery removed. I thought maybe there is gas in the house, but the alarm in the basement didn't go off(even when I took it upstairs) and my dog doesn't sniff anything right now i got all the windows open.. but should I do anything else? when the alarm went off, my mother was taking a shower could water vapor has anything to do with this?
They shouldn't be. They should be connected to a driven ground rod. The lightning rod, invented by Benjamin Franklin, are placed at regular intervals on the highest portions of a structure. A lightning protection system typically includes a rooftop network of conductors, multiple conductive paths from the roof to the ground, bonding connections to metallic objects within the structure and a grounding network.
It's impossible to say without seeing the ductwork and unit, but I think the installer got lazy and didn't properly install the air return duct. Any competent HVAC tech can tell you if this is or isn't the problem. If it is the problem, you'll need a HVAC tech or sheet metal worker to make and install the ductwork anyway.
