If you’re a seasonal homeowner or snowbird in Boca Raton, a clogged AC drain line can silently turn into a costly disaster—especially when you’re not around to catch it.

In hot and humid climates like South Florida, including Delray Beach and Highland Beach, blocked AC condensate lines are one of the most common HVAC issues. If left unchecked, they can cause:

AC system shutdowns
Mold and mildew growth
Water damage to ceilings or flooring

At Boca Raton Home Watch, we make sure this doesn’t happen on our watch.
