Factory installed LL dryer

service

i was surprised to see units with no liquid driers, and asked about it, and was told by the tech at that company that ' one is in the unit" and i said " well, yeah, but you are still supposed to put a drier in, man, in fact you are kinda supposed to come and replace it after a lil bit too on retrofits and change outs"

Customers don't want to pay for a burn out driver removal.

Your not suppose to have 2 LLFDs in series on a system.

On a swap out. If you suspect that the line set is dirty/contaminated. Install a suction line filter. And then remove it in a week(or replace line set when you do the swap out).

I have always put a LLD at the evap when we used equip shipped with own drier in the condenser.

Just double insurance.

Years later. When another company works on it.
The tech usually only changes the inside FD, and leaves the old one in the outdoor unit.

And thats the one that ends up being the cause of the liquid line temp being 10° cooler then the outdoor ambient.

Double restriction. Not a good idea.

Properly sized LLD not a prob. Factory said so.

What factory? I'd need to see that in writing. I've repped for several different brands for the manufacturer, and having more then one liquid line filter drier in the liquid line would be a reason to void the warranty.

Someone, from somewhere may have told you it was ok, but you won't get anyone from the manufacturer to put it in writing. If it isn't in writing, it don't exist.

My Goodman rep. he gave it to me on a company letterhead years ago. It was a bulletin.

Well, I have a comprehensive list of all Goodman bulletins going back to the mid 1980's, and I can't find anything making that claim. I have also turned down labor claims on repairs to systems that have multiple filter/driers for Goodman products and have never been questioned by anyone at Goodman Manufacturing.

One of the main concerns at Goodman Manufacturing Technical Service Manager meetings was how to keep contractors from installing a second filter/drier in the liquid line.

Well you know how The Old Guard was over at Goodman before and after the sale of the company: The Right Hand Did Not Know What The left Hand Was Doing.

A Goodman engineer with a British accent told me that when he was touring the local Goodman (Than they were Flo CO) wholesalers.

He had a funny way to pronounce Capillary tube. Ca-pilla-ry it sounded like.

If you are referring to Goodman's chief engineer for the furnace division, the only engineer at Goodman that I know of with an English accent (along with a Texas drawl), he would not have suggested multiple filter/driers.

I was with Goodman during the changing of the guards, through two major changes. I can't imagine anyone in authority at Goodman who would put in writing that it is ok to install an additional liquid line filter/drier. Not to mention that it is not accepted anywhere else in our industry.

Just tellin 'ya what he told me when we were at lunch. And he forwarded a bulletin to me a few days later.

Let me guess; you no longer have the bulletin, remember the guys name or have anything whatsoever to help us out here

hvaclover

The English guy.

Who keeps old bulletins any way?

Naw you're right. I have no bulletin. I just wanted to get a little vinegar outta you.

How you feeling any way Robin.? Keeping fit and calm I hope?

The drier shgould not be inside the condensing unit. I gueess there are to many problems with people not installing them,I sure wish they would just send it with the unit and let us install it ,oh wel lwishfull thinking.

RoBoTeq

I'm with you on this one. Unfortunately, too many installs were being made without filter/driers installed and compressors were failing prematurely.
