Radiant Plumbing & Air Conditioning

What this contractor is listed for

If you notice water near your indoor AC unit, a musty smell when the system runs, or your air conditioner shutting off without warning, the issue may not be major equipment failure. In many San Antonio homes, it’s a clogged condensate drain line. Your air conditioner removes humidity as it cools. That moisture drains through a small pipe called the condensate drain line. Over time, algae, dust, and debris can build up inside the line, blocking proper drainage. Common signs of a blocked AC drain line include: • Water stains on ceilings or water near the air handler • Musty or mildew odors when the AC runs • The system shutting off due to a triggered float switch • Higher indoor humidity or sticky air Because HVAC systems in San Antonio run for long cooling seasons, condensate drain line clogs are one of the most common and preventable AC issues we see. Routine AC maintenance and drain line cleaning help protect your home from water damage and unexpected cooling interruptions.
