Air conditioners do more than cool air. In the course of cooling incoming air, your air conditioner usually forces some of the air's moisture to condense. This condensing reduces the overall moisture content of the air that the system eventually dumps into a home, making the air conditioner an effective dehumidifying device.
Unfortunately, the presence of this condensate usually encourages rusting in the evaporator coil area. Rust not only exposes the air conditioning system to the risks of a refrigerant leak, but also increases the chances of an air conditioner shutdown. Here is why regularly cleaning your air conditioner's coil will go a long way towards minimizing the risks of an air conditioner shutdown.
Evaporator coil rust and condensate drainage system clogging
Rusting simply breaks down any exposed metallic surfaces in the evaporator coil area. The rust particles eventually break off. And when they do, they usually fall into the condensate collector tray. This is a problem since continued accumulation of these particles in the tray can sometimes block the tray's exit. And even if they don't, they usually find their way into the condensate drain lines. And since the drain lines are narrower, they eventually end up blocking them. This usually reduces the effectiveness of the condensate drainage system and thus leads to water backups, something that then causes some of the water to overflow.
Condensate drainage system clogging and air conditioner shutdown
The condensate overflows that result from a clogged drainage system usually leads to water flowing into the condensate overflow tray. And as long as the air conditioner runs, more water will continue flowing into this tray. With time, this continued accumulation will trip the condensate overflow switch, something that will then cause your air conditioning system to shut down.
Preventing air conditioner shutdowns through cleaning
The trick to preventing this type of air conditioner shutdown is to keep rust particles from accumulating in the condensate drainage system. An easy way of doing this is by getting rid of the evaporator coil's rust layers by cleaning them. Following this cleaning with a proper rinse will prevent the settling and accumulation of any rust particles in the condensate drainage system, something that will then eliminate the risks of clogging-caused air conditioner shutdowns. You can also follow this up by using a wet-dry vacuum to remove any unwanted particles from the drain lines. Doing this will guarantee a clog-free condensate drainage system and thus reduce the risks of air conditioner shutdowns. For more information, contact a company like D & R Service Inc.
