This is probably and multi position handler. With out a pic it is hard to say but if a condensation line is installed then yes the hole should be plugged. You can get some 3/4 PVC plugs pretty cheap.

http://www.firstco.com/products/hbxb_hw.asp

there are two 3/4 drain holes to the left and two at the bottom as the unit stands upright.... one at the bottom is connected to the pump that drains outside. The other three are opened... does this effect the overall proficiency if there left open? both my units have no caps on them and I don't like my plumber....

Plug the holes. With the holes not plugged you are letting are out and you want the air to run in the ducts

Multi position air handlers have many knock outs and drain lines for different positions IE; Vertical, horizontal, up flow, down flow, right side blow and left side blow.

The drain holes are also there for a reason which is the lowest drain hole is the Primary drain which you run to a drain or outside, the next higher hole is the secondary drain or (emergency drain) that is used when and if the first (Primary drain) blocks up the water will rise and come out the secondary drain so as not to ruin your ceiling if the A/H is installed in the Attic. I always run a separate secondary drain to one of the bathrooms over a tub or shower that way if you ever see water coming out that drain you know the primary drain is blocked, so clean it out fast.

Here is the Emergency drain line images you requested.

I inform all the people living in the house to notify me or someone if they ever feel water dripping or see water dripping out of this pipe.

Most people take a shower daily so someone would see this.

I just showed the pics to my wife and a coulpe of friends ad they said;

People pay for that sh!t...I pay for a pro job and OMG!

I can't believe people put up for that. Looked like a nice bath until that.

How do you stop bugs and spiders from coming in?

Ever heard of water sensors to shut off the condenser when the pan drain is plugged?

MR Plumber not MR HVAC

I knew you were setting me up because I remember your wise guy a-- from many posts before.
You didn't know the answer to the question and said to plug all the openings.
By the way I have the drain pan in the attic TEED into the emergency drain.

I also have used water level sensors in drain pans. The answer I gave was not the only one out there but at least it was a valid one not just telling people to cap them off.

So MR T--d chaser keep on chasing and leave the Air Conditioners alone.

PS You must be awfully bored to be showing your wife pictures of A/C jobs.

Wow, this is "hack" if I ever saw it. (should go in the "wall of shame" section at the other HVAC forum)

This is word for word from a major Manufacture installation manual 2009.
CONDENSATE DRAINS
Route primary drain to the outside or to a floor drain.
Check local codes before connecting to a waste(sewer) line.

Route secondary drain line to a place in compliance with local installation codes where it will be NOTICED when unit is operational.
Condensate flowing from secondary(overflow) drain indicates a plugged primary drain-unit requires service or water damage will occur.

Now how many pin heads install equipment without reading the information ??? probably you and Plumber 101. You guys know it all.
Now where is there a better place than the bathroom shower or tub to notice an overflow condition???
Yes pan floats are OK we have all used them, there are many ways to install units. You DIYER'S Plumber 101 and you have to get with it.

Yes, I spend lots of time naked in the shower stall without the water running just waiting to detect a condensate overflow condition

Just chop another hole above the homeowners bed. At least that might get noticed.

I used to run overflow condensate pipes above sinks. Never directly from the unit though. It would be run from the overflow pan under the unit. This was only in commercial settings. The other place would be above a window. In a residential setting, a overflow pan float is used and the drain is capped.
