How can I find out how big an AC unit (in tons) the house truely needs?
Have or do a manual J on the structure.
Is it worth $4K to switch from instaling 2 Amana brand 14 SEER AC units to 2 Trane brand XR13 units
NO not if it is the same size equipment.
I feel like I'm being punished (in the form of $4k out of pocket) for requesting the TRANE brand in stead of the Amana. The TRANE has a warranty twice the duration of the Amanna
I would check the warranty again. Amana has 10 years.
TRANE has a better track record over time.
Who says. Amana is Goodman and Goodman is good.
The quality of all products has more to due with proper install that equipment name.
I however am not certain that it's roughly a $2K difference per unit and therfore that the $4K out of pocket cost to me may include some extra.
If you do not know Im sure do not know.
Have a totally different company do the HVAC if you are so unhappy. The builder will allow a credit I am sure.
Here are some specs on the house and the systems so as to help better address my questions.
House Sqft: 3400
Stories: 2
Window Count: 25 (approx.)
Region: North Texas/Dallas Area
Other: Attic includes Radiant Barrier Foil.
Desired Average Indoor Temperature: 72-74 (warm months only)
Have a manual J done or you do it, IT is the ONLY way to tell what you actually need.
You forgot the most important thing!! Duct size and placement will make or break a system. Do or have a manual D done. It is the only way to be sure of proper duct size and placement.
Air Systems That comes with house:
Brand: Amana (2)
Rating: 14 SEER; 3.5 tins down stairs & 3.0 tons upstairs
Model: Unknown
Save your $$ stick with Amana. For 4000.00 extra it is a looser because you are getting NOTHING extra for your money.

Personal note
First The name means nothing without a good installer. MayTag , Goodman , Amana , Intertherm ,
Delta Therm , Miller, Trane, American Standard, and a host of other have the same 10 year warranty throwed in too. Then a host of
Other have 5 years everything and 10 years compressor. The 10 year warranty is a common thing now days.
Now the Amana and Goodman on 13 seer or up have life time warranty on the compressor.
Now all this said about here. Warranty is needed only if you don't get a good installer. If given a choice of getting a life time
Warranty on everything or get a good installer. I would take the good installer . I shotgun the units and do not recommend any but
Just listed them.
Now here is what I think here. Look the first thing you should be looking at is the installer and next to the last thing would be
The brand. I would take , first a brand that was a pure piece of junk if I knew it was installed by a good installer before I took
The best brand know to man installed by a Hack. The installer is the key to a good running system. Warrentys are for people who
Don't get a good installer or a bad installation. Hacks and bad installers brought on the long warranty game as it is today.
