Where I live, you get a buildup of snotty mold in the pipes. You can also get bugs living in the pipe, or snakes. A solution is to put 1/4 cup of Clorox in the drainpipe to kill the snotty mold about 2-3 times a year.<br /><br />But (there's always a but) make sure you don't put the Clorox directly into the drain pan or anywhere where it will directly touch your veins, else you will trash your system.<br /><br />Andrewnoreply@blogger.comtag:blogger.com,1999:blog-5837660608809488753.post-11248783585442024442016-09-10T23:46:02.068-04:002016-09-10T23:46:02.068-04:00I had a PVC drain line that stopped draining.

A trip to the Big Box, and some fun with PVC and I was back in <br /><br />I had similar problems in Florida, but in that case the drain line was a breeding ground for algae no matter what I did. <br /><br />And don't discount the filter change. That will screw up a lot of stuff in an AC/furnace.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5837660608809488753.post-19066581632688778982016-09-10T22:54:45.099-04:002016-09-10T22:54:45.099-04:00Anonymous:

That is what is known as a clue that dissolution was taking place. <br /><br />If it was so safe, why did my Freon decide to escape within 1 hour of product application?<br /><br />I stand by my original position, use those cleaners with caution, it could be a very expensive cleaning of your wallet along with the now clean coils...Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5837660608809488753.post-1348263542120428432016-09-10T17:24:20.521-04:002016-09-10T17:24:20.521-04:00I'm managing it by raising the setpoint.

I did this on a marginal installation once and solved the issue...

First new house and the A/C was just *barely* keeping up. I had heard about those coils needing cleaning so I scampered off to Home De(s)pot for some coil-cleaning-goodies.<br /><br />Better living through chemistry in hand, opened up the evaporator (A-coil) and got to cleaning. (Spray-spray-spray) Wow! This stuff is amazing! Dingy-gray oxidized aluminum now bright and shiny! Rinsed off thoroughly with fresh water, mopped up and put it all back together.<br /><br />Me so smart! (Patting self on back).<br /><br />Uhhhh... Wait a sec here... Why is there no cold air coming out the vents? It's starting to get hot in here...<br /><br />Did I mention the A/C was just keeping up because it was August in Florida???<br /><br />The coil cleaner was a Phosphoric acid cleaner. Phos acid is a fairly benign acid, as far as acids tend to go. It's edible, like glacial acedic acid (vinegar). (It's a flavoring agent in Coca-Cola, for cripe's sake!) <br /><br />It etched a hole through the aluminum coil.<br /><br />I got to sweat a few weeks until I could afford the $1700 for a new A/C.<br /><br />Me not so smart.
