Central HVAC Water Leaks: Causes and What to Do
Why water shows up around your indoor unit and how we find the source.
Water around your indoor HVAC unit usually points to condensation that isn’t draining properly. Left alone, it can damage ceilings or floors. This guide explains common causes.
What to check
- Is the condensate drain line clogged?
- Is the drain pan cracked or overflowing?
- Is the filter dirty, causing the coil to freeze and then drip?
- Is the coil iced over?
- Is the unit level so condensate drains correctly?
Common causes
- A clogged condensate drain line
- A cracked or rusted drain pan
- A frozen coil from low airflow melting and dripping
- Improper drainage slope
- High indoor humidity producing more condensate
A LITTLE CLARITY BEFORE YOU DECIDE
Frequently Asked Questions
Why is water leaking around my indoor unit?
The most common cause is a clogged condensate drain line; a cracked drain pan or a frozen coil can also cause leaks.
Should I turn off the system if it’s leaking?
Turning it off can prevent further water damage. Then call for service to find and fix the source.
Can a dirty filter cause a leak?
Yes — a very dirty filter can make the coil freeze; when it thaws, the excess water can overflow the drain.
