DIY Steps to Fix Leaking HVAC Air Conditioner
Ready to fix leaking HVAC air conditioner issues yourself? Grab a wet-dry vac and some elbow grease—here’s how:
- Turn off the power—no one likes a shock with their fix.
- Find the drain line—usually a PVC pipe near the unit. Suck out the gunk with that vac to clear a clogged drain line.
- Check the filter—if it’s dirtier than a mud pie, swap it out to avoid frozen evaporator coils.
- Inspect the pan—cracked? Seal it temporarily with waterproof tape.
Last summer, I used vinegar to unclog my drain line—worked like a charm! These steps can fix leaking HVAC air conditioner drips in under an hour if you’re lucky.
