Featured condensate drain guides
Air conditioner drain pan full
A full AC drain pan usually points to a clogged condensate line, bad slope, or a stuck condensate float switch. Start with safe cleanup and simple checks before buying parts.
Air handler condensate pan full
Find out why an air handler condensate pan is full, starting with the safest checks. Learn when a clogged drain line, bad float switch, or damaged trap is the real problem.
Air handler overflows when ac runs
If your air handler overflows when the AC runs, start with the condensate drain, trap, pan, and float switch. Check the safest common causes first before replacing parts.
Air handler water after humid day
Find out why your air handler is leaking water after a humid day. Start with the drain, pan, airflow, and sweating checks before replacing condensate drain parts.
Air handler water around unit after storm
Find out why water is around your air handler after a storm. Start with rainwater vs condensate clues, then check the drain line, pan, float switch, and nearby roof or wall leaks safely.
More condensate drain problems
Air handler water in secondary pan
Find out why your air handler has water in the secondary pan. Start with the common drain clog checks, separate overflow from sweating or leaks, and know when to stop and call for service.
Boiler condensate leaking
Find out why boiler condensate is leaking by checking where the water starts, whether the drain is blocked, and whether the trap or drain line is split before buying parts.
Condensate drain backs up each summer
If your AC condensate drain backs up every summer, start with the outlet, trap, and slime buildup before assuming a bigger HVAC failure. Here’s how to sort out the common causes safely.
Condensate drain backup
Find out why your condensate drain is backing up, where to check first, and when a clog, float switch, or damaged drain line is the real fix.
Condensate drain clogged
Troubleshoot a clogged condensate drain by checking for overflow, a tripped float switch, and a blocked drain line before replacing parts.
Condensate drain clogs after rain
If your condensate drain clogs after rain, first separate a true drain blockage from rainwater intrusion, a sagging outlet line, or a buried discharge end. Start with safe visible checks before replacing anything.
Condensate drain drips after rain
Figure out why a condensate drain drips after rain by separating normal runoff, a clogged line, a bad trap, or rain getting into the drain termination.
Condensate drain float switch tripped
If your condensate drain float switch tripped, start by checking for standing water, a clogged drain line, or a stuck switch before replacing parts.
Condensate drain freezes
Find out why a condensate drain freezes, how to separate a simple cold-spot issue from a clog or airflow problem, and when to stop and call an HVAC pro.
Condensate drain gurgling
A gurgling condensate drain usually points to a partial clog, a dry or dirty trap, or poor drain pitch. Check the drain line, trap, and pan before replacing parts.
Condensate drain leaking
Find out why a condensate drain is leaking by checking where the water starts, whether the line is clogged, and whether the trap or float switch has failed.
Condensate drain leaking at joint
Find out why an HVAC condensate drain is leaking at a joint, starting with loose fittings, clogs, bad slope, or a cracked trap. Check the leak pattern before replacing parts.
Condensate drain line keeps clogging
If your condensate drain line keeps clogging, start with the outlet, trap, and slime buildup before assuming a bigger HVAC failure. Here’s how to clear it safely and spot when the line or float switch needs replacement.
Condensate drain line sweats
Find out why a condensate drain line is sweating, when it is just humid-air condensation, and when poor drainage, missing insulation, or an airflow problem needs attention.
Condensate drain overflowing
Find out why a condensate drain is overflowing, starting with safe checks for a clogged line, full pan, bad slope, or failed float switch before water damage gets worse.
Condensate drain overflows after filter change
If your condensate drain started overflowing after a filter change, check filter fit, airflow direction, drain slope, trap blockage, and float switch issues before buying parts.
Condensate drain overflows at startup
Find out why an AC condensate drain overflows right when the system starts. Check for a partial clog, bad slope, blocked trap, or float switch issue before replacing parts.
Condensate drain pan full of water
A condensate drain pan full of water usually means a clogged drain line, blocked trap, bad float switch, or poor drainage slope. Start with safe cleanup and simple checks before replacing parts.
