Summertime Air Condition Issues

It's hot now in the end of July in SWFL, so air conditioners do two things, they cool your house and they break.  

This week I had two clients with air conditioners that were shut down due to a plugged drain line.  One a new house and one a older condo.  What makes this significant is with a biweekly service you can be hot and humid for 14 days until I return.  This is long enough for mold to get started.  I now recommend weekly home watch visits.

I opened the clients door and found the conditions in the photo to the right.  It was very hot and stuffy, I knew something was wrong immediately.  The thermostat was set to 74, the system was ON and calling for cooling.  The drain line sensor had been tripped by too much water in the line.  I drained the line into a bucket and the air came on and was cooling so I knew the drain line was the root cause.

A service guy came out "cleared" the line and left.  On the surface the problem was solved, but the root cause was not yet fixed.  Being a Home Watch professional I checked on it the next day just to be sure and now it was 85 degrees in the house!

House was under warranty but plugged drain lines are not covered.  Make sure you have a air conditioning maintenance service agreement in place even if the house is under warranty.

The photo above to the left is how I found the line when it was not draining.  I moved to the angle in the photo to the right, and it was then draining.  Permanent fix was for the piping to be changed to get more drop before getting to the wall.  This was a build issue that took a while to surface with a marginal drainage system.  

A weekly Home Watch visit will catch these issues sooner, so which is best?  I would choose the weekly visit to help me prevent minor damage going to disaster.  An empty home is a vulnerable home!
