That AC Drain Is About to Dump on Your Ceiling

Last week in Battle Creek started hot and stayed that way. Monday through Wednesday ran the high 80s into 93 on Wednesday. The AC never quit. Then Thursday and Friday brought thunder, a 43-mph gust, and about three-quarters of an inch of rain on Friday alone. By Sunday night the low dropped to 54. That is a ceiling leak week, not a wait-until-October week.

While the outdoor unit ran, it made water. That water is supposed to leave through a thin condensate line into a drain or a pump. After days of continuous cooling, algae and sludge plug the line. The pan fills. The overflow hits the drywall, the closet, or the basement ceiling below the air handler. Look at the pan and the line this week. If it is wet where it should be dry, or the pan is full and the line will not clear with a gentle flush, call A.W. Crooks. See also our AC Repair · Air Conditioning page. We are 24/7 residential plumbing and HVAC in Battle Creek and the surrounding areas, and we do not add a weekend tax during hours. Call or contact us.

Same walk: your water heater. Rust at the base, a wet ring on the floor, or an 8-to-12-year-old tank is this week. Got a big AC replace quote already? Free Second Opinion, or contact us. Primary path for cooling: Air Conditioning.

After Friday’s storm, check the outdoor disconnect and any breaker that tripped and will not reset, and look at the AC condensate line again. A crushed outlet or a pan overflowing is how a ceiling gets it in September.

If the job is commercial new-build or a multi-family rough-in, we will point you to The Plumbing Company instead of pretending it is the same truck.
