Is there a "quieter" air handler?

The better half is about ready to throw a hammer into our Armstrong. Told her that'd be even noisier-didn't go over well.

Lennox CBX32MV air handler is the very quiet. Assuming the duct system is sized ok

[jrbenny]

Any air handler is quiet if the duct is sized correctly.

Is this their top of the line AH?

yes, very quiet with a properly sized duct system.

[jjer]

Yes. If you want a really quiet outdoor unit the XP15 by Lennox is suppose to be the quietest.

A lot of the noise could be from the ductwork... have it checked out before you replace to ensure proper sizing and ample supply and return.

Just curios. Don't you have to increase the register grill and box size when you
go from...say 8" duct to 10" duct?

That can make for a less than asthetic look on a wall or ceiling.

Also, say you wanted to increase the duct work...would 8" to 10" make
a noticable reduction in air noise in an 887 sq. ft. condo with 2 Ton?

Or would you have to go even larger...and thus a more uglier sized register?

Do you want less noise or a smaller register?
This is your choice. You've asked the question 100 different ways on this forum.
Increase the duct size AND register.
Are you really going to notice the difference in size?

Nah...just when I have my eyes open, or try to sell the place later on.

Your replies to mine keep getting more useless.

I asked if going from 8" to 10" ductwork and larger register is a significant enough upsize to
make any appreciable difference in noisy airflow. I can handle increasing my current 12 x 6
duct box to the next bigger size (which is a register box for 10" flex ducting).

A bigger wall register would be needed.

Ya I don't want to get gigantic ugly on my walls. Is that hard to comprehend?

I live in a condo...not a gymnasium.

To anyone else following this, I just recieved a rather large shipment of 2" thick fiborous material which I just cut and fitted into my hallway closet cavity return area.

Huge improvement in sound.

I've ordered more sound blocking/absorbing 1" closed cell foam for the furnace closet, which is located in my lap (small condo).

I'll forgo increasing the duct size, but run a loop duct off the plenum back to my "too short" LR vent box.
Don't worry, I will mosey it back in a round about way as it should go.
That should practically take care of my "noise" issues and all my posts here.

It's been fun, but i got more help from ppl with a home theatre system and AC noise than
you nuts and bolts types here.

hehee. Also...damn, quieting down a system in a small condo can get expensive with all the "materials" out there.

You guys have been cool.

im thinking that you have a vertical airhandler and are using a closet for the return theres two ways to get it quieter and perform better
1) turn the blower fan speed down
2)add a return somewhere else and tie into it (make two grills one in the closet one in hallway or living room connect with say 10" flex use 12x12 return boxes) you wouldnt need any filters because its using the closet) ** this is a pass through
if im wrong make the plenum bigger and add a return (meaning it was horizontal Goodluck

If the duct work is designed right, just about any modern air handler will be quiet.

I have a 14SEER Trane with a variable speed blower in my basement. My basement is VERY quiet.

If I am standing right next to the air handler, I can hear it. If I am anywhere else in the basement and listen very carefully, I can hear it.

Upstairs, I put a streamer on one of the registers so that I could tell when the blower was on. Even with everything else in the house off, it is impossible to hear.

Don't you cool 4000 sq. ft. with 2 tons?

yes, and VERY proud of it <GRIN>!!

I've had 2 ppl to tell me that, in similar words. Hodgepodge of weird angles. The only part that would be saved is the trunk of the ducts.

Thanx once again Mr HVAC Installer from 1993 w/the kinky hair that kept getting calls from his girlfriend.

Have you been b!tch!ng over this system for 15 years? Man, you need to get a hobby or something.
