Our furnace would not turn on during the first cool day. Technician came out and found 2 gallons of water in the furnace box- motor shorted, everything damp, not good. We recently had sprinkler system installed 2 months ago outside and one of the new sprinkler heads was spraying water around the outside furnace intake pipe valve. Technician believes 2 months of spraying (3 days a week) was drawn into the pipe towards the furnace inside and collected. Does this sound possible?

Sounds like a reasonable answer to your problem. The only other way for water to get into the furnace is if the A coil pan was leaking or the basement flooded. Looks like you will need a splash shield installed around the furnace pipe. Make sure the person doing the install knows what they are doing OR it can create other problems.

Thanks so much for the answer- appreciate it.
