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...

Directly below the closet is my kitchen/dining room.

Yes, forgot to mention that I've got a 12x12 return on the side of the closet for more airflow-- I plan on changing that to a filtered return,...

Yes, sadly it serves both floors of the house-- that's what they do when they build houses down here in south FL!

So is the heavier door with a 24x24 return in it a bad idea? I was thinking I...

Cool :)

Picture 1 is in the handler closet-- you can see the filter on the bottom. When the handler is on, the filter is getting pulled upward into the unit.

Picture 2 is a larger view of the...

Thanks for the reply. I'm with you in that the door is not the problem, but the ducted return elsewhere isn't really an option.

I'm wondering whether I can remove the bi-fold door and replace it...

Hi all--

I've got a 4-ton American Standard 16 SEER system with a powerful GAM5 air handler. The system is great (though a little loud) but I've had an air filter problem as of late.

My handler...

So what are my options now for making this thing less noisy?

IT's a 4-ton blower to go with a 4-ton condenser. My contractor advised me to go with a 3.5 ton handler because the blower was so powerful and might be too loud for me. Why in the hell I didn't...

Loud doesn't begin to describe it. It's like I'm in an airplane bathroom-- my wife is extremely displeased, and to be honest, I'm a bit upset that I spent several thousands of dollars upgrading to a...

What exactly is the "return box"? I've got a handler on a stand. Does that mean on the interior of the closet?

Fan noise mostly, with some airflow noise too.

I saw in an old post from 2006 that Bald Loonie suggested building a box underneath the unit and lining it with sound-deadening ceiling tiles. I've...

PS: I realize that I might need to provide more info. The handler is located on a stand in a large closet and there is one return-- under the unit. I'm wondering if the noise might be reduced greatly...

Hi all--

I just had an American standard 4-ton split system installed. The air handler is very loud when it's on and my wife is giving me grief because our old 1987 Trane 900XE didn't make that...

Take it easy there. I'm in South Florida as I've mentioned frequently in my other posts in this forum. I have several contractors that I'm currently fielding bids from, but I wanted to know whether...

Hi all--

I am about to replace my old 1986 4-ton Trane AC system with a new American Standard system. My contractor tells me that the air handlers for American Standard actually outperform their...

While I have you all here, you might be able to help me with the final stage of my decision making process:

I'm currently deciding between an AS Gold XM Air Handler (multi-speed) and the Gold XI...

Thanks everyone. Don't worry Vegas-- I can count on one hand the number of times I had to use the heat in my house over the past two years. Gotta love South FL!

Is it an efficient arrangement or should I look to go with a unit like a Rheem that has a coil under the blower? What would you all do in your houses?

It'll be a regular ol' vertical install and my cabinet has plenty of room. Thanks for the input, I guess that means that I can go with American Standard and not worry about potential catastrophes....

Hi all--

My contractor tells me that the newest Trane/AS air handlers have the blower located on the bottom of the unit and are mostly made of plastic so that they can't corrode.

My question is...

Hi everyone--

First off, thanks to all who helped me decide that I should go with a 16 SEER system in a previous thread. Especially Baldloonie.

I'm replacing my old Trane AC system (circa 1986)...

I'm a bang-for-the buck kind of guy. It's not necessarily that I'm adverse to the idea of getting something made outside of the US, but right now Florida Power & Light is giving a $780 rebate (am I...

Hey Baldloonie and others--

Thanks for all the help. I'm out of the Rheem builder's model game. I'm going to do a bit more research and find some other models and brands that look good to me and...

Eeek. I don't like the sound of a Mexican-made builder's unit. So basically this is a base model Rheem without any kind of modern efficiencies like multi-speed blowers and multiple stage compressors?

Ok I just got the model number for the Rheem. Does it look like a solid unit?

Condenser model :14AJM49A01
Air handler model : RHLLHM4821JA

Thanks all-- so is this quote missing anything important? And should I tell him not to put a suction drier on?
