What should I do if my mini split is leaking water inside?

If your mini split is leaking water inside, turn the system off and have the condensate drain and indoor coil inspected, cleaned, and cleared. The most common cause is a backed-up drain that lets condensation overflow from the indoor unit. Once the drain is clear and the coil is clean, the leak typically stops without major parts. Our technicians handle this repair routinely in homes around Clarence Center. Annual professional maintenance includes drain cleaning and coil service, and Comfy for Life members receive that visit each year.

If safe to do so, try these quick checks before service:

• Clean the indoor unit’s air filters.
• Visually check the drain path and connections for obvious blockage or dislodged tubing.
• After filters dry, restart briefly; if dripping returns, shut it down and schedule service.

Do not run the unit if water is dripping near electrical components. <br/> Updated: 2026-05-01 <br/> Need help in Clarence Center, NY? Call (716) 216-5332 or book online. "They installed a mini split and central air in our house in under 7 hours." — Caron K.
