Why is there water pooling around my air handler?

The most common cause is a clogged condensate drain line causing the drain pan to overflow. Turn the system off and call us — the pan can fill and overflow within hours, causing water damage.

Can a clogged condensate drain cause mold?

Yes. Standing water in the drain pan creates an ideal environment for mold. We flush and treat the drain line with algae inhibitor during every visit to help prevent future clogs.

Is water from my heat pump dangerous?

Some dripping from a heat pump in heating mode is normal — it's the defrost cycle melting ice. A large puddle or water inside the home indicates a problem that should be addressed.

Professional HVAC Leaking Water in Asheville & Western NC

Seeing water around your HVAC system is alarming — water damage and mold can develop within 24-48 hours, so this problem needs fast attention.

What Causes an HVAC System to Leak Water

The most common cause is a clogged condensate drain line. As your AC cools air, it removes moisture that drips into a drain pan and flows through a drain line to the outside. Algae and biofilm buildup can clog this line, causing the pan to overflow. Other causes include a frozen evaporator coil that's thawing and overwhelming the drain system, a cracked or rusted drain pan, improper installation slope, or a failed condensate pump.

Quick Things You Can Check

Locate the condensate drain line — it's usually a PVC pipe coming from the air handler to the outside of your home. If it's visibly clogged or no water is dripping from the end during operation, the line is likely blocked. Turn the system off to stop water flow and place towels to prevent further damage. Check your air filter — a clogged filter can cause the coil to freeze and then thaw, creating excess water.

When This Becomes a Serious Problem

Water damage to floors, drywall, and ceilings is expensive to repair. Mold can start growing within 24-48 hours of sustained moisture. If you see water leaking from the AC unit specifically, along with reduced cooling or ice on the coils, the problem involves more than just a clogged drain.
