The most common calls we receive at Hamstra Heating & Cooling during the Tucson monsoons include the following phrases:
“There is water dripping out of my AC vent.”
“We have water coming from our mechanical closet and has soaked our carpet”
Uncommon … No.
Preventable … Yes.
What can cause air conditioning water leaks?
Clogged Drain: A clogged drain hole/line causes the drain pan to overflow. During the warmer months of the year when the air conditioning unit is working hard there is a lot of moisture being pulled out of the air in the home. As this water drips down the evaporator coil and into the drain pan, there is algae and other debris that form and run through the drain line. Eventually, if not maintained, this algae and debris clogs the line, forcing the water to overflow the pan.
Busted Pump: Leaking water could be a sign that you have a busted condenser pump. If the pump is broken it may not be properly pumping the excess water from the drain pan, causing it to overflow.
Improper Air Flow: It is possible that the air flow over the indoor evaporator coil is restricted due to either a dirty coil or a dirty air filter. In either case this will cause the evaporator coil to ice up and leak water over the edge of the condensate drain pan.
Proper maintenance of your heating & cooling system can help prevent water leaks. However, the desert climate, including dust and critters, can cause drain clogs between maintenance visits. A condensate drain safety shut-off device can drastically prevent water damage and is required per code IRC M1411.3.1.
