For the past 2 summers when it is extremely hot outside water is surrounding the base of my furnace. I lived in the house for over 10 years and prior to the past 2 summers this was never an issue. I opened up the door where the condenser coil is located while the ac was on and water is not making it to the drip pan. It drops from the coil into the base of the duck work/ furnace. Any ideas would sure help I don’t have a clue what it could possibly be.
