Yep it is a little fishy I would gladly pay 3% more for the two stage

I would want the two stage aszc unit myself. The system will be much more efficient and comfortable. Yea the numbers may match but I promise you will save more with two stage.

I believe the newer...

Thanks for sharing that Brent, imagine if Doug and Jim could forgive each other and Jim could help wth the software design it would be truly amazing!

Sounds like txv valve thumping on off cycle.m

Depends if they chose the right motor with matching specs.

They must run a vacuum to remove all the nitrogen before they let the r22 back into the lines! If not you will have now compounded the problems.

This is like a last ditch effort to find a leak...

Those installs look plain awful. You shouldn't have round flex ducts connected directly to the furnace and yes the plywood does look like it might give way.

I'm the guy who was having the issue. There was never ....and still is not necessary to have any profile to get air side data as far as I can tell. I've been playing with it all weekend trying to...

I noticed the target temp split is different according to what profile you select. Has it always been like this or is this new with the update? If you could please clue me on the reasons that target...

I just found out today while I bought some and am now researching what is going on. You guys always seem to know what's going on. Should we stock up now even though it's twice as expensive as last...

Variable speed motors are a little misleading to customers that they will be slowing down and speeding up while heating/cooling. This is not true unless you got a higher end multi stage outdoor unit....

Constant torque motors are programmed to simply as the name implies maintain programmed torque on the shaft. As the airflow decreases the load on the shaft decreases and the motor will draw more...

I have at least 8 pair love em. Carpenter pants extremely durable

You have to that spec from the grille manufacturer that you are testing. Hart and Cooley has good specs online you can usually find one that is close to one in the field

im not defending the install but nothing wrong with the supply coming off top of plenum box. At least it had one. Around here they will try and put the round directly to the furnace/coil

Wrong thermostat is all I will say. This is not a DIY site.

It's called expanded ratings and the true capacity of any machine is constantly varying with indoor temp and humidity and outdoor temps. Im not sure what spec sheet you referenced but there is no one...

Don't underestimate 5 tons of cooling ! 3200 sqft sounds about right to me still probably not getting full capacity as it is extremely difficult to move 5 tons worth of air though most duct systems.

I think the unit may not be wired or configured right and only running in 2nd stage. Most of my 2 stage units run around 9 or 10 in hi and 6-7 low

That brings up another issue that should be adressed. Search orphaned water heater to learn more.

Probably due to sealing up the air leaks which cause outside humid air to be drawn indoors.

Unfortunately asking for a load calc from the company doing the work will lead to fudging of the numbers so the computer spits out what they think and have proposed already. As a Florida native...

You probably Had a restriction the whole time like jtrammel tried to warn you about

But then it would not be an approved tape

No rinse cleaner does absolutely nothing unless you are cleaning a already clean coil.

It's obvious to me that the problem is air flow and that is because of ductwork and filters not being enough for 4 tons let alone 5. A smaller piston will cause it to freeze faster as the pressure...

Not the greatest design ever. It was York being cheap and trying to be smart by using a standard drier on a heat pump and having it act as a muffler also.

I have done a few spray foam homes here in northern Florida which is actually a warmer climate according to design temp charts and I'm doing 900-1000 sqft/ton. This will most likely be much smaller...

It does put contactors on edge when customers ask specifics because usually that means they are researching it online and will then give them headaches if everything isn't done just as they pictured...

Would you consider standing it up vertically in the garage, they last a lot longer and much easier to service that way. Your installer can get a pre made metal box called a coffin box for a very...

I'm in Florida and we do use a lot of ductboard. However it should be feasable to have it metal although it may be more difficult to find the right contractor to do it and it will be 2-3x the cost....

I use these a lot on longish lines with txv indoor but piston outdoors.

Don't want to damage that motor doesn't look like it can come out past those lines! Argh!

You just put it on the application and they may or may not even verify it.

Low charge is a different animal because it doesn't have the volume of gas at 80 degrees that you will with a high suction pressure.

I've never experience a compressor overheating with 75 or even 80 degree suction temp. Unless there was an electrical issue also or over amp situation.

I'm pretty sure his head pressure would be...

Mr bill killed his reserve cells long ago haha

I'm a little confused about which filter is in what system but to clarify - the system with aprilaire can possibly use ez flow but would work even better without any additional filter.

On the...

So as a drier cycles from 100 degree while system is running and then 120-130 in an attic when it cycles off doesn't affect its moisture holding capability until it's near full capacity?
How about...

That's easy it ain't goona be. It's his own house

It would work then just tune the airflow for 2 tons and you're good. Nay not dehumidify quite as quick but the run time will make up for it.

Are the coils going to be in series of how are you...

Both condensors feeding one coil? Can't do that

Just don't use pleated filters in the grilles with the addition of the media filter.

Is the PD much higher on 410a? Let's say 140/320 = 180 PD

70/225 = 155 PD

I wouldn't spray foam the attic now because that will just lower the dew point more and make more condensation. It will also take an already oversized 2 ton system even more grossly oversized which...

Ok I just haven't noticed either valve being different physical sizes. Maybe it's something you couldn't tell right away. Maybe the Sporlan people will chime in.

I've not noticed the diaphragm being larger on 410

[QUOTE=hvacrmedic;23477201]

I thought that the bulb pressure and suction pressure was a net zero balance of forces and the spring pressure would be the cause of opening or closing so I can't think...

No because they are interchangeable without power head replacement for the proper refrigerant
