My AC unit is over flowing the water pan and the HVAC guy thinks it may be a main plumbing issue because is happening to 2 different units simultaneously.

Who’s a good plumber that services Mandeville?

Update - The AC guy found a leak in the coils and showed me where the coils are icing over. He said the melting ice is over flowing the system.

Drip pans aren’t tied into the the “main plumbing”. It’s usually just a pvc run that empties onto the ground outside of your house

Edit: A little research after other posters corrected me shows that AC condensate lines can, in fact, be run to sinks.

My coworker had his second story bathroom sink overflow and flood his bathroom. AC drain line is tied the sink drain and algae grows and clogs the drain.

Not true. Some condensing units drip into the plumbing line on sinks. Overflow pans drain outside, usually.

If A/C units are in the attic the drains would tie into the vents in the attic.

if the house main was backed up, water would back up into the tubs/shower drains first. the the A/C drains tie into the same vent stack then you "could" have an obstruction in the vent stack itself, but unlikely.

my first thought is the condensate drain line has algae/crud buildup and needs to be cleaned out.

EDIT:

bleach should be poured into the A/C drain periodically to prevent this issue.

I’ve seen 2 ac units incorrectly run to 1 drain pipe before. This would cause problems for both units if the line got blocked.

the condensate line ties into the plumbing waste/vent system. The safe pan, by code, either needs to have a float switch that will kill the unit if the pan fills up, or the drain line on the pan needs to go to a place where it will be seen notifying of an issue.

you should never have water in the safe pan unless there is an issue.

Drain pipe possibly has a p-trap and it gets clogged. Every year before summer time when unit sweats alot, I pour Clorox in p-trap

Probably clogged drain somewhere. Algea builds up in them sometimes.

Is anything dripping from the HVAC drain pipe? It's probably a narrow PVC pipe protruding from one of the walls of the house. Trace it from the pans in the attic to check.

Sometimes water heaters are rigged to overflow into the ac pans too. You don't have an overflow there right?
