And does it still move 1600 cu.ft if the handler is set on the lowest fan speed, or would it be lower?

About five inches of room between the air handler and the door jamb. What kind of rough surface insulation would you recommend?

Out of curiosity, what are some of the common signs or symptoms of a system that isn't getting enough air?

The insulation board is going to be tossed in the trash. Right now I'm just using it to mimic a door without having to actually buy and hang one. The sound board will be attached to the back of the...

I've got a 12x12 in the office, so in total I've got a 24x24 and a 12x12.

And squeezing the air is a bad thing? With the soundboard box, would I just leave the front open and have panels on the other sides?

It's a 4-ton American Standard GAM5 air handler and the size of the return under the unit is 22"x20". In addition to the 24x24 filtered return you see pictured, I also have a 12x12 filtered return in...

Hi all,

I think I've found the solution to my noise problem with an open return 4-ton AS GAM5 air handler. As many of you may recall, I've been tossing around the idea of replacing a louvered...

So do you guys think this may have compromised my equipment? On the GAM5, the blower is underneath the drain pan so it got wet.

Nope, just gunk from probably many years of neglect by the previous owners of this house. Why exactly is that insulation blanket a bad idea? It really cut down on the noise quite a bit.

Thanks all. It wasn't a low-bid job-- I went with a new system because Florida Power & Light, the electric company, was doing a big rebate for 16 SEER systems if you went with one of their authorized...

Not that I can see. But do you concur with secondopinion in that this is my contractor's fault and he should be paying for the ceiling repair?

But bottom line-- the installing dealer is responsible for fixing my unit and for the repairs to my home? I don't think I should have to pay to rip out, replace, re-skim, and re-paint a portion of my...

By installing dealer do you mean the company/contractor that installed the unit or the distributor who sells the units to the contractor? And has this damaged my unit at all?

Hi everyone,

About a month ago I had an American Standard GAM5 system installed in my home to replace my old Trane XE 900 system. All has been going well (aside from the noise) until tonight when...

This is a 4-ton American Standard GAM5 system. My house is 2300 sq feet, and my previous system was a 4-ton Trane 900 XE circa 1986 that was much quieter. My contractor warned me that the AS system...

Yes sadly that's how my earlier system was set up. I've learned that a majority of the builders here in South FL went for the cheapest and easiest installation of AC systems, hence the single return....

Hi all--

I've got an AS GAM5 system with an open return. As many of you have told me, one of the reasons why it's so noisy is because it's an open return and because the GAM5 is a positive...

Not to hijack the thread, but in your experience Duckman, have you found that the new Trane/AS systems are a bit noisier than the older ones because they went to a positive pressure system and the...

I have the GAM5 air handler and mine leaks air too, and I was also told that it was normal operation. My technician used foam tape to seal it.

I'm going to go with your suggestion, just need to find the appropriately sized metal filter frame. Any idea where the best place to buy one would be?

@Dave-- Yes! I put the filter inside the unit and now it's not falling down anymore, though it does get pulled up a bit when the handler is running, regardless of whether the door is open. I am...

The noise is not a big deal to me. All I want to know is whether replacing the bi-fold louvered door with a slab door w a 24x24 filtered return grille is a good idea or if it will cause problems with...

It cools perfectly well. My energy bills have gone down, the airflow is good-- far superior to the old 1987 Trane I replaced.

The only real problem is that the filter gets bent out of shape by...

Ok, so now that I have everyone's attention, what do you think of my plan to move the filter from the unit to a 24x24 return grille in a slab door and installing a 12x12 filter grille on the side of...
