Summer Guide
HVAC Condensate, Attic Water Heaters, and Hidden Summer Leaks
Summer's dramatic water arrives by thunderstorm, but summer's expensive water usually arrives by appliance. The machines that keep a Georgia house livable work their hardest in July, and several of them handle water while they do it, above your ceilings, inside your walls, and behind your appliances, where a small failure runs unwitnessed for weeks. The losses in this guide rarely make anyone's storm story. They quietly account for an outsized share of the water damage we dry every summer.
The pattern they share: each one telegraphs its failure in advance, to anyone who knows where to look. Here is where to look.
The Condensate Line: Your AC Is a Water Appliance
Every hour it runs, your air conditioner wrings moisture out of Georgia's air, many gallons a day at the height of summer, and all of it leaves through one modest drain line. In our heat, that line grows algae and slime the way a birdbath does, and when it clogs, the water backs into the overflow pan and then, if the pan's float switch is missing, stuck, or unwired, through the ceiling below. An attic air handler makes the geometry worse: the failure point sits directly above bedrooms, and gravity handles distribution.
Two habits neutralize most of it. First, find where the condensate discharges outside and glance at it on humid days: a steady drip means the line is working, and a bone-dry pipe in July means a clog is forming somewhere upstream of it. Second, learn your secondary drain, which builders route to a conspicuous spot, often over a window or eave, precisely so its dripping annoys you into action. The mystery drip over the window is not a mystery. It is a warning by design, and painting over its stain is shooting the messenger.
The Attic Water Heater: A Tank Above the Ceilings
Metro Atlanta builders put water heaters in attics by the thousands, which saves floor space and raises the stakes: when a tank past its first decade lets go, dozens of gallons plus a live supply line arrive through the ceilings of everything below, and the loss reads like the house is raining indoors. If your tank lives upstairs, three things earn their keep. A drain pan under it with its own drain line, actually routed somewhere, and clear. A leak sensor in that pan that alerts your phone, which costs less than dinner. And a replacement decision made on the calendar rather than the failure, because a tank at the end of its service life in an attic is not a question of whether.
Know its shutoff too, on the cold line at the unit, since the first-hour protocol is a lot faster when the valve is not a scavenger hunt.
The Supporting Cast of Small Lines
The rest of summer's quiet losses come from lines you could cover with a hand. Rubber washing machine hoses harden and split, usually mid-cycle, which is why braided stainless replacements are the cheapest insurance in the laundry room and why running the washer or dishwasher while nobody is home is a habit worth breaking. Plastic ice maker lines behind refrigerators kink and pinhole. The supply connectors under sinks and behind toilets fail at their plastic nuts, a drop an hour, into the cabinet floor, for a season.
And a pattern worth knowing if you live in a subdivision: houses built in the same two-year window installed the same components in the same two-year window, so when a neighbor's water heater or supply fitting fails, treat it as the street's early warning rather than their bad luck. The parts do not know whose house they are in.
The Ten-Minute Monthly Walk
Once a month in summer: glance at the condensate discharge outside, shine a light into the attic at the pan under the air handler and the water heater's base and fittings, run a hand along the cabinet floor under each sink, and look behind the washer at the hoses. Add the water bill to the routine as the leak instrument it is, a habit the crawl space and slab guide explains, and scatter a few leak sensors at the usual suspects, which amounts to hiring staff for the price of batteries.
When you find dampness, or a ceiling stain appears, resist the urge to solve it cosmetically. A stain is travel evidence: water moved from somewhere to there, the path is almost never straight, and drywall that feels dry can read wet on a meter. In this climate the gap between finding moisture and drying it properly is measured against a 24 to 48 hour mold clock, which our mold prevention guide explains. For anything beyond a tightened fitting, the Marietta water damage team traces and dries it to measured targets, and 911 Restoration of Marietta answers around the clock.
