How to Fix a Full Drain Pan Yourself
Hopefully this goes without saying, but before do any repair work on your HVAC unit, TURN THE POWER OFF! Once you do this, the first thing you want to ensure is that the drain outlet is functioning properly. Use a shop vacuum to remove any standing water first. Remove any dirt of excess debris from the pan and ensure that the drain outset is not blocked so that it can properly drain.
Next, inspect the drain line itself and ensure that it isn’t kinked or obstructed in anyway. Look for any cracks or holes and replace the drain line if needed. Check the drip pan and ensure that it’s not sagging in the middle and that it has a proper slope towards the drain outlet. Ensure that the pan’s support brackets are properly installed and are not damaged or missing. Also, make sure the units coils are not frozen and there are no leaks. If you know how, check the units refrigerant levels.
At this point, if any of these more serious problems exist, we highly recommend you call your local HVAC contractor to have your unit properly repaired.
