PIPE HOLE in first photo is dripping water. Then it stops and after some days or next day starts again. Sometimes it is dripping 2 gallons of wate in aggregate.
what is going on?
How can I fix this?

It is condensation line for hvac. It was not dripping water before. Now it is. Dripping 2gallons of water does not seem normal.

 

[Inept1]

what do you mean by running ac? Are you talking about cold ac for summer or heat for Winter? I was runnmg heat and after temperatures rose switched to cold ac for summer.

Is it possible you were not running the AC before ? Now you are ?

 

[Inept1]

It did not drip when cold ac was ON before. Why is it dripping now when cold ac is ON?

 

[Inept1]

The question is why was it not dripping when cold ac was on during summers before?
something is not right here.

 

[Inept1]

I did not miss it.

It did not drip when cold ac was ON before. Why is it dripping now when cold ac is ON?

Well, you probably just missed it or just didn't look on a more humid day. If it is the ac condensate drain it was dripping. Unless the line was broken or clogged and it was draining into your attic or a wall.

Looks like a secondary drain line. Check your main drain line to see if it's clogged.

where is main drain line?

 

[Inept1]

Could the clog be cleared from the drain line shown in photo? Assuming that is the secondary/emergency drain line.

Looks like a secondary drain line. Check your main drain line to see if it's clogged.

The main drain line might run down a side wall and terminate just above the ground or it could be directed into a rain gutter on the house which you might not be able to easily see from the ground. The secondary drain line which is what is probably in the picture is the emergency overflow and will have water coming from it if there is a problem with the system or the main drain line is clogged. The emergency drain line is generally placed like yours over a window where it will be easily seen. Sometimes (lousy installation) the emergency drain line will be tied into the main drain line. Find the main drain line and check for blockages. The system may possibly have a problem which has caused the emergency overflow.

The unit is built in the attic on the second floor.

what are exact names of tools that I can use to clean from the attic? How do I blow air?
and I have to clean the secondary line too?

No, you have to clean each line separately. You generally go from the inside coil and run some bleach, and/or blow with air. I suppose you could also ream them out with a flexible wire if you had to. Sometimes the installer will leave you a tee and a removeable cap to get access. Sometimes not and the line has to be disconnected. If you haven't even looked up there to see what you have by now it is probably best to do as noted above and get a pro in. This isn't rocket science but the access and working conditions in an attic can be difficult.

Since the company that installed it several years ago, The hvac unit had lots of different issues. The people they send lied about fixing it , tried to deceive me, and the person taking calls at company is not expert at hvac issues and so would take at word the bs lies their workers told her.
