AC Condensate Drain Cleaning
If the AC drain line clogs, water backs up, a float switch shuts the system down, or water appears near indoor equipment, CTS can check the drain, pan, safety switch, airflow, coil condition, and related cooling problems.
AC drain cleaning and water leak repair
Air conditioners remove moisture while cooling. That water has to leave through the condensate drain. When the drain clogs or the pan cannot drain correctly, you may see leaks, ceiling stains, float-switch shutdowns, musty smells, or intermittent cooling.

Drain Problems
Common condensate drain calls
Condensate drain problems often show up with AC leaks, frozen coils, and maintenance issues.
Drain line backup
A blocked line can back up into the pan, trip a safety switch, or create water where it should not be.
Safety switch shutdown
A float switch may shut the system off to reduce water damage, which can look like a thermostat or no-cooling problem.
Frozen coil connection
A frozen coil can thaw into a water problem, so airflow and cooling performance may need to be checked too.
Drain Cleaning Service Work
AC water leaks, drains, pans, and airflow
A clogged drain line can become both a cooling problem and a water-damage problem.
Drain line checks
Drain line routing and condition are checked during condensate service.
Drain access
Drain access points and cleanout details can matter when a line backs up.
Pan and coil checks
Drain problems often involve the pan, coil, airflow, no-cooling, and freeze-up issues.
Condensate drain FAQs
Answers about repair, replacement, maintenance, and service.
Can a clogged drain shut off my AC?
Yes. A float switch or safety switch can shut down the system to reduce water damage when the drain backs up.
Is a clogged AC drain urgent?
It can be urgent because water damage can spread quickly. Water location, active leaking, and whether the system is still running affect how urgent the drain problem is.
Can maintenance prevent drain clogs?
Maintenance can reduce risk by checking filters, airflow, coils, and drain condition, but no maintenance plan can guarantee a drain will never clog.
