I was set and ready to go for a Fourth of July barbecue and cookout my wife and I were hosting this year at our brand new house. We had already invited both of our families and at least a half a dozen friends and coworkers. We even encouraged everyone to bring dishes and do a quasi-potluck in addition to the food I would be cooking on the grill. I had bought raw chicken, pork, and several beef steaks and stored them in our extra refrigerator that we have in our garage. On the morning of the cookout, I was walking to that fridge when I saw a small pool of water on my garage floor. There was a wet patch of concrete about four feet by three feet that led back to the wall shared by my house. The concrete was damp but not completely soaked. I immediately worried that I had a pipe leak of some kind and hastily looked inside the house on the opposite side of the wall where the pool of water was, and discovered it was a closet in the master bedroom. The thing is, I have a plumbing diagram for our house and I discovered that there are no pipes anywhere near the place where I found the puddle of water. I went back into my garage and realized immediately where the water was coming from. Directly overhead is my air conditioner air handler and it appeared to be dripping condensation from the bottom panel onto my garage floor. I called my HVAC supplier to look at it the following day and they recommended that I install a secondary or auxiliary drip pan—it supplements the existing drip pan inside the air handler where most of the water is pumped out when the machine is running properly. Although if it is considerably hot outside—especially in the garage—and that hot air meets the cold metal surface of my air handler, preventing condensation from forming and dripping is an uphill battle. But with a secondary drain pan underneath, any extra moisture drips off into the pan and dries when the machine is powered down.
