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...

What should the numbers be in a properly functioning unit?

I have a call into a company that has been around some time and have them recomend what to do. The house heats fine, but it's just the...

So will they need to replace the Ducane indoor coil then since they aren't matched, or is there some way that they can make it work?

Also, is there a way to increase the airflow? Bigger blower...

I ask the builder numerous times for this information, and I have never been given the information from the installer.

As far as going legal, what could I possibly go for?? I bought the house...

Nothing.... they told me I might need to replace the coil is all they said. What do those numbers tell you?

Sorry to double post, but with regards to the subcool and superheat measurements above, is there a typical target that you should shoot for or is it different for each application? I know I have...

The hard part is funds are not easily available right now, so I'm trying to mitigate the cost if possible. I hear what you are saying though.

I did call a different contractor last summer. They...

I moved into a new home 4 1/2 years ago and a Whirlpool HVAC was installed in the home. I've had continual issues with the unit and the whole installation (undersized return lines, lack of air flow...

The strange thing is this is a VERY reputable company that has been around for over 40 years. Great Angies list rating and great word of mouth reputation in my area.

SO is that the fix (generally speaking)? I've got the unit working again (I went outside and lightly tapped on the connections and it has been running fine for the last week. The A/C guys said they...

General question.... if I have three supply vents in a room, should I also have three return vents, of the same size, in the room? I'm just trying to understand my airflow a bit better. Schedule J...

I know.... I'm almost wondering if it wouldn't be less expensive to just have a whole new system installed or just have the current one fixed.

Ouch....sounds expensive.

One thing I do remember. When the clown who worked with the builder installed the unit, it wasn't charged. We didn't find this out for some time after we had been...

So the coil would be replaced but I would have to pay for the install?

Just spoke with the owner of the company that came out last year, and he's telling me they can't get out to see me until next wednesday. Well, I wish it was sooner, but he said he would come out and...

I'm still not sure I follow exactly what you are sealing though? Any gaps around the register (where it connects to the duct)?

Not sure I follow this... what exactly are you sealing?

Guess what.... it's now spring and the heat is back... and the AC is frozen over again.... I have a call into the company that fixed it last fall as they never did call me back on what their...

Why is it my fault? Shouldn't a good contractor ask "is it frozen up" and then say wait until it defrosts then we will come out? All I knew is it was freezing over and had no idea how to fix it. I...

Damn... then that means another service call. :(

Sorry, one more thing. The tech just came back after disconnecting his stuff and checking a few more things and said "after knocking around the capillary tubes and piston, it seems to have loosened...

Well, they came back and here is what they told me.... still not fixed.

"Coil looks clean from the underside. All but 1 of the cap tubes on the evap coil were icing, high subcool, low suction. ...

Why do I want to do that beenthere? It's already defrosted.

No, I listened to the stupid Realtor (who is a friend of mine) who said "It's a new home, why do you need an inspection?" Live and learn I guess.

I'm sure there are many problems with the system....

Okay, now I'm as angry as a midget with a yo-yo.

Contractor came out, looked at the unit and said I can't test it until the unit thaws out. That will be $XX please.

Why would you send someone...
