A/C Drain Problems?

Came across this flyer on the bulletin board at one of the condo buildings where we check units. It's an offer from Service America at two price points. During the course of checking units, over time, we have encountered a number of clogged drain lines which can cause one of two problems...the condensation from the A/C fails to drain properly and backs up into the condo causing a flood or it causes the kill switch that many of the newer A/C units have and shuts down the A/C completely. If you haven't had your A/C serviced for awhile it might be worth looking into by contacting them at 1-800-314-4621.
