@hvacexplained: One of the most common calls I get down here in Florida is caused from a clogged drain. Anytime I perform maintenance or take a service call. I am adamant on cleaning drains. Nobody wants a call back. Keep customers aware to not block drains and do your part by flushing them correctly along with a pan treatment, whether it be anti-sludge tablets or a drain pan sprayable enzyme. Some people prefer putting vinegar down the drains, but I prefer using hot water, use a vacuum cleaner on the end of the pipe, followed by using a PVC flexible brush. There are times where I use a little bit of condenser coil cleaner in very bad situations. ##local725##local449##commercialhvac##hvac##hvaclife
