Quick HVAC tip from a service call in Bowie today 👇
We cleaned out a clogged AC condensate drain line, and the homeowner asked why the water and buildup coming out of the line was so brown.
It’s usually a combination of dirt and debris, bacterial/slime buildup, and sometimes rust or sediment that makes its way into the drain system over time.
One simple thing homeowners can do is periodically pour a little white vinegar into the condensate drain to help keep buildup under control.
We also use condensate drain tablets as another preventative option.
And even if everything seems to be working fine, we recommend having your HVAC system serviced twice a year — once before cooling season and once before heating season. Catching a partially clogged drain early is a lot easier than finding water around your furnace or air handler later.
Hope this helps a few of our Bowie neighbors!
