There are many systems on the market, I am pretty sure you can find a unit to meet your financials, and the space you have.

If you post the size of the space you have here someone might be able to...

I got the YJ 2 weeks ago. I have no idea why I did not have one already, great tool, I am going to wait on the reverse bender until I really have a need for it though, very pricey.

Ah yes the big South Florida dealers........ Ever wonder how they get so big ??

Make sure you do all you can as has been mentioned here. If you do have future problems any licensed contractor can...

Is your air handler sitting on top of a plenum box ?

If so it could be that moisture has gotten into the ductboard from a previous leak in the old ahu and you may have mold growing in there.

It...

The question is not what a cap costs or where it is made but, why did it melt in the first place ????

Is it possible that a cap just goes bad ? sure, is it possible something caused the cap to...

Trane is nice for sure, but there are plenty of other systems on the market.

Whatever you do decide on, your contractor must do a thorough inspection of your home and load calc before any...

As long as the old line set meets the size requirements there is no need to change them.

For once, a happy customer !!!

Very nice, clean looking install. Obviously a company that takes pride in their work.

I hope you have many years of trouble free comfort.

There not in front there in his head :eek2:

Rheem is my brand of choice, and I would rather sell it than any other brand.

As said already, it is all in the install.

There is no need to build a closet in the garage for it, a nice stand and r/a and s/a glass duct with a 3' high wrap of sheetmetal for protection will look great and allow much easier service.
...

I have installed quite a few Rheem ultra series units in the last year, I have not yet had a complaint or call back.

Sizing is key ..............

Your point about ripping off customers is a valid one, and one that I have spent a lot of time trying to figure out how to stop, maybe one day.

The majority of the guy's here are stand up business...

There are several foreclosed properties in my neighborhood and the a/c and water systems have been taken from them.

Along with the vandalizing it's going to cost a pretty penny to put these houses...

No big deal on how the unit is secured........

You must have a P trap so that your unit will drain correctly......

The picture of your AHU shows the pvc pipe (drain) next to that is another...

Yes Sir, that is correct.

I am going to guess there was no permit pulled on this.....

There is no cond trap, you can see the elbow on the floor in the condenser pic.....

There is no aux drain, safety switch.......
...

David, to be sure that you are getting the right equipment please insist that your contractor does a load calc and shows it to you. with the description of your home, going by square foot to size...

Two compressors is what you mean. I am not a Trane dealer but I understand that when running both stages your energy savings will not be very good.

My point was that your ductwork that is there...

Sounds good, if they are putting the ahu in the garage and adding return duct I am going to assume the stat will be near one of the new return grills.

The only thing that concerns me is the fact...

It has been common practice in commercial work for quite some years to hang from the top chord of all trusses.

The top is load bearing the bottom is not, most prints stipulate all suspended items...

Well now that just depends on where the leak is, if it is drawing in hot humid air (cooling) or cold outdoor air (heating) there is no energy gain short or long term.

I like to think of a duct...

Not just that, it is also caused by the filter not fitting correctly and leaks in the return duct after the filter or gaps in the cabinet.

All contractors in South Fl are not the same.

It sounds like zoning your house will be the better bet, but you must take into account that you will have to have your duct system completely...

You have got me curious, my contact info is in my profile.

You either have an exhaust or a window (that opens), standard down here anyway is an exhaust fan.

Just a thought ! we have seen the same kind of scenario, what we did was run a o/a duct right up to the return of the fan coils with a damper, (within 6" or so) that did the job for us.

Like I said I don't do resi, but we did do a thirty five million dollar house on the beach last year, same deal install the duct and seal,inspection then wrap.

It is a lot different down here as...

Let me just say this, when I install duct in commercial buildings I have to leave a minimum of 2" for insulation for code compliance, not to mention the insulators would kill me if I did not leave...

I am so glad I don't do resi, if it were me doing the install I would have left at least a 2" gap all around the duct so that the insulation does not get compressed, squashed insulation loses it's...

I bought my first digital tool last year, I like it well enough but think I need to go back to school to figure out how to work all of the parameters on it. :D

I felt like a complete novice using...

Your answer is in your question , the building mechanical was not designed for the load put on it by a server room, there is no comparison in the load's of a Conference room verses a server room.
...

I hope your not implying your contractor told you to do it !!

All ductwork for heat or cool (and in most cases exhaust) should be sealed when installed, it is part of the job not an extra and...

Not to sound like a complete d#$% here or upset anyone, but down here in South Fla I prefer long sleeves and it is proven that the more you cover up the better off you are, I can't find one article I...

Here in Florida residential and a lot of light commercial is ductboard, I hate working with it, I will say that if installed correctly it will last and if needed can be cleaned if the person cleaning...

Did you try here?

If you tell us where in Florida your villa is I am sure you will get some help with your question.

Failing that, when you get here ask your neighbours who they use.

How much control do you want !!

Might be worth a phone call, I have installed many of these in light commercial but mainly dealt with the 2100 series.

It is not too late to ask for it and you should not consider buying without it.

Trane, Carrier, Ruud, York, lennox, Goodman,you name it, none will work correctly if sized wrong.

Bid to clean everything with a note stating that you have done so because you cannot inspect the complete system at this time.

Probably should be another thread but, I want to know why we have to jump through all these hoops for license and insurance and ("EPA testing" or you cannot buy equipment ) and yet a building owner...

Unless there is an obvious obstruction in your system (plugged filter ) it is wise to shut it down and let the ice melt and then call for service, there are several things this could be and a tech is...

Well then Sir your issue is with your GC not the a/c contractor, he works for the GC and provides what is either on the plans or what the GC requests.

You are right, you got what you agreed on with your contractor, I am going to assume you only had one price to do your job, otherwise you would have more of a clue about what you are getting, you...

In no way does it make you a hack ! I have quite a few analogue gauges and spare parts lying around, I did buy the yelow jacket digi earlier this year, and after getting used to it am starting to see...

As big as you can make it !!

Seriously, once you figure out your equipment you will have a good idea of the size room you will need, just remember that you have to duct in the return now, so that...

You will be hard pressed to find a "Crap" unit, plenty of crap install's though!

I am surprised your dealer did not discuss this with you, we are all different in what we require for payment, I for example on the completion of a half or one day system changeout require payment in...

Sounds good to me, why not post the model #'s of your new equipment and then I am sure the guy's here will give you things to look for.

It is of my opinion that seeing as you have chosen a dealer to do your work, means that you trust in him, obviously you know what you are getting and for how much as you have signed a contract, the...
