Is that because you want to wring out more moisture, so you need the colder coil, hence lower CFM?

While I understand this statement, I had a contractor tell me this weekend when he was fixing my system that one company manufactures most of the coil's and then stick that vendor's name on them. ...

How do you determine the right CFM? I would think that slowing down the fan would allow the coil to blow cooler air, but less air?

So if the service guy comes out and splits a Coors lite can in half and wraps it around the line to see if the mountains turn blue, that's a bad sign?

:eek2::LOL:

Thanks gang... that's what I figured. We used to use the setting where we would let the house heat up while we were at work and come home and be miserable. I set it yesterday to be the same temp...

...I think.

Okay, well we had someone come out and they replaced the coil on the unit (see previous post for history) and it seems to have fixed the issue. I have a ton more airflow at the...

That goes without saying, but could there be something else that would make them not matched?

In doing some searches on google, I do see some information when I type "ACU Evaporator Coil" and...

Lol... the only thing that comes up when I type in the model number is this exact thread.

So why would I have two different contractors tell me it is not matched? Granted, one is Whirlpool and the other is Ducane, but both said that's besides the point, and something about capacity, etc.

On the condenser, I am told that I have a 3 1/2 Ton unit. The model is Whirlpool WCA136A-1A. How can I tell if that is correct? Does the 36 in the model signify that (if so, am I to assume that...

Why? Because they don't have lips? :)

Is a normal stud pocket the ones that go down the walls between the studs?

Panning? I assume that is the sheet metal that is used to enclose the studs to make a chamber in the basement?

What...

So if you have a 12x6 return in a wall (upper part of a stairway), could I have a contractor enlarge it to 12x12 and achieve anything? I'm just looking for low hanging fruit to increase my return...

Silly question, but can you have too many RA vents?

Also, if you needed to add extra vents, would it just be possible to make some vents double the size (either wider or taller)?

Well, that's what I don't know. I had one contractor tell me that they both are toast, and another tell me maybe not. Both seem to believe the coil is shot (both said that they can't be fixed - non...

So are you saying it might be able to be fixed? I thought the compressor and the coil was non serviceable?

I have had nothing but problems with my HVAC unit as have been detailed in my previous posts, and I can not find anyone willing in my area to service my Whirlpool unit. I called Whirlpool/Tradewinds...

Well, I'm in good shape other than the crappy install that the installer did... and the fact that the compressor is dead because he put a mismatched coil/compressor and some other shoddy work. Other...

If I did have noisy ducts, what would that mean? Too much air pressure?

In the summer, not all the rooms match by a temp or two, but in the summer all do (I believe as they all are comfortable). I'm sure we may have to tune the duct dampers a bit.


As far as fan...

Z... why will it do a great deal for airflow? Because it has a bigger (or more efficient fan)? Couldn't I just buy a more efficient fan and have that installed?

But do I really need to get a whole new furnace? When my parents got AC, they had it added to their existing furnace. Same with our neighbors. I have no issues with the furnace and it seems...

Zach... I'm sorry but I'm not sure I follow you. It might be cheeper to buy both what? Compressor and?

Thanks Kevin.... That's kind of what I figured.

Well, I had a different contractor out here today and he couldn't believe it even lasted 4 1/2 years. He checked the Ducane coil and the Whilpool compressor and he said they are mismatched. The...
