One other addition I forgot to mention was air returns. Around here the builder puts in one per system. We added one to each of the trouble areas and it really helped. Unfortunately its more air...

The problem you could gain cooling at the expense of humidity control, so you have cold damp air instead of warmer dry air.

I'm in AZ and I had almost the exact situation as you. I had a 3.5T...

The test for my new system will be my August bill. Last year was $400, and this was with an inside temp of 84, which is still a bit warm, and the 84 was only maintained in the center of the house....

House is 3000 sq ft. single story.

I'm not a contractor, but I did have four of them give me quotes and a pretty detailed analysis was conducted by each, because this is required by our utility...

I can't comment much on the capacity, other than to say the home came with a 3 1/2 ton and a 3 ton unit, and they didn't cool enough. Even still this number can be a bit misleading. We have the...

Terminal Cooling Temp Rule-of-Thumb

I needed to have two AC split systems replaced, so I got quotes from several contractors. All four recommended the same two size units, a 4-ton unit and a 3-ton unit, but I remember several of the...

A 3-speed air handler is really a 1-speed air handler. If you want a variable speed air handler, they have that.

O.K. Maybe a stupid question but I have to ask. Why a 21 SEER 4-ton AC for a small 1800 Sq. ft. weekend home in Northwest CT? My 4-ton AC cools my 3000 sq. ft. home in Phoenix.

You didn't give all the specifics, but if your return IN the bedroom is sucking much more air then the one OUTSIDE the bedroom, it is likely sucking most of the air for that unit.

So I'm assuming this HVAC unit is just for the master, or a room or two around it. So do this test. Close your master door so its only open maybe 1/2 inch. Does the door slam closed or open wider...

My plan is to try to replace the ceiling diffusers first. If I can get ones that will pass more air without being noisy, that should be good enough.

If that is unsuccessful, I'll go the...

I guess that spells bad news for all zoned systems since slow air flow, or fast air flow with chilled air going around a bypass damper is about the same thing.

O.K. I read and read from every direction, and I think I understand it now. I understand why the BK doesn't work with a single compressor system. Just seems like a bad design on Trane's part.

That actually changes things. From your pictures you can't tell if those white and red wires were jumpers or different wires.

If these are different, it is my guess that they go to the outside AC...

If it was me, I wouldn't just rely upon wire color to tell you if its right, because colors can vary. Having said that, you may have some problems.

Not sure why you have that Red wire and White...

So I thought I understood it, but maybe not. If I wire it so Ylo gives 50% fan, and Y gives 100% fan, and I enable BK like it spells out, what speed do I get with Ylo + BK? and Y + BK?

I certainly don't disagree. But at the same time, unless there is a financial incentive for others to care about it, nobody does, and certainly the builder doesn't. They want to do things as cheaply...
