Heil air conditioner indoor coil rusted or leaking refrigerant

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Corrosion of coil tubing, Formicary corrosion, Mechanical damage to coil, Poor condensate management causing corrosion

Safety first: Turn off power before opening the coil cabinet. Refrigerant leaks must be handled by a licensed technician.

Step 1 – Look for oil stains: Inspect the coil and connections for oily residue, a sign of refrigerant leaks.
Step 2 – Check condensate management: Ensure the drain pan and line are clear so water does not sit against the coil.
Step 3 – Technician repair: A pro must confirm the leak, then either repair small accessible leaks or replace the Heil evaporator coil assembly and recharge the system.
