What to check in the house today
No alert, no freeze and no unusual rain right now.
- Once a month in cooling season, look in the air handler drain pan. Standing water there means the condensate line is backing up.
- Turn off every tap and watch the JEA meter for 15 minutes. If the dial moves, look for a hidden leak.
- Want a sense of the drying work for a leak you already have? The estimator walks through it.
