About Our AC Leaking Water Service Appointments

If your AC is leaking water inside your home or around your system, it usually means something is blocking or disrupting the normal drainage process. In many cases, the issue is a clogged condensate drain line, a full or damaged drain pan, or a frozen evaporator coil that is melting. It can also be caused by a dirty air filter, low refrigerant, or a malfunctioning condensate pump.
While some water around your system may seem minor, an active leak can lead to ceiling damage, drywall issues, mold growth, or system shutdown if not addressed.
If you notice water around your indoor unit, we recommend turning the system off to prevent further damage until it can be inspected.
After you complete the short form above, an LB Chase comfort advisor will contact you within 1–2 hours during normal business hours to schedule your appointment. During your visit, our technician will inspect your drain line, drain pan, evaporator coil, airflow, refrigerant levels, and overall system operation to identify the exact cause of the leak.
We will explain what we find in clear, straightforward terms, review your repair options, and help you decide the best next step for your home. If the issue is simple, we will resolve it. If the system is older or the problem points to a larger issue, we will walk you through your options with no pressure.
LB Chase Heating & Air has been serving Sevierville, Maryville, Seymour, Kodak, Pigeon Forge, and surrounding East Tennessee communities since 1995. Our goal is to protect your home and restore comfort with honest diagnostics, clear communication, and reliable service.
Frequently asked questions about why your AC is leaking water
Why is my AC leaking water inside my house?
Your AC is usually leaking water inside because the condensate drain line is clogged or blocked. When the drain line backs up, water overflows from the drain pan and can leak around the indoor unit. Other causes include a cracked drain pan, frozen coil, or condensate pump failure.
Is it normal for an AC to leak water outside?
Yes. It is normal for your AC to produce condensation and drain water outside through the condensate line. However, water leaking inside your home, pooling around the unit, or dripping from the ceiling is not normal and should be inspected.
What should I do if my AC is leaking water?
If your AC is actively leaking inside, turn the system off to prevent further water damage. Then schedule service to have the drain line, drain pan, and system inspected. Avoid running the AC until the cause of the leak is identified.
Can a clogged drain line cause my AC to leak?
Yes. A clogged condensate drain line is one of the most common reasons an AC leaks water. Dirt, algae, and debris can block the line, causing water to back up and overflow from the drain pan.
Why is my AC drain pan full of water?
A full drain pan usually means the water is not draining properly. This can be caused by a clogged drain line, improper system leveling, or a damaged or rusted drain pan that is no longer draining correctly.
Can a dirty air filter cause my AC to leak water?
Yes. A dirty air filter can restrict airflow, which may cause the evaporator coil to freeze. When the ice melts, it can overflow the drain pan and lead to water leaking around the unit.
Why is my AC leaking water after being turned off?
If your AC leaks water after shutting off, it may be because ice on the evaporator coil is melting or the drain system is backed up. This delayed leaking is often a sign of a freezing issue or drainage problem.
When should I call an HVAC technician for a water leak?
You should call a technician if you see water pooling around your indoor unit, dripping from the ceiling, repeated leaks, or signs of water damage. If the system shuts off unexpectedly or the leak returns after cleaning the drain line, a professional inspection is recommended.
