Our house is built on a concrete slab. Our furnace is in the garage as well as our water heater on the inside wall. We have water that is leaking out into the garage and we have figured the source to be coming from the furnace area. Is that possible. The main water line into the house runs in the wall behind the furnace and water heater.
sounds like the drain pipe for the air conditioner coils is plugged preventing the water from draining properly. there should be a pipe coming from the side of the furnace and going into a drain line or a condensate pump. you will need to clean this pipe. if you have an air compressor, remove the pipe at the furnace and use the air compressor top blow the obstruction for the pipe. if no air compressor, you will need to use a wire to run thru the pipe. the pipe is normally not cemented at least at one point in the run to allow disassembly and cleaning.
