I had another call today about water on the floor around the furnace. This is an inevitable problem with all air conditioners if you do not do preventive maintenance on your A/C system.
As you all know, an air conditioner rings gallons of water out of the air as it cools your home. This water is drained from the evaporator (“A” coil) by gravity through a hose connected to the front of the coil, above the furnace.
The “A” coil has a drain pan on it’s bottom which catches the water to be drained away. The “A” coil also catches dirt in the air stream which mixes with the water and will eventually build up enough to clog the drain fitting and hose, causing the water to overflow the pan and run onto the floor around the furnace. Be sure to check the drain system for debris and replace the hose periodically. We recommend an annual maintenance plan which will leave this messy job to our service technicians.
