What size do you have now?

What size is being quoted?

Post back.

IMO

3 Ton replacing with same size

Do I understand you have zoning controls? Please elaborate.

You have on-off thermostat and zoning board controls operation of system?

You want the 042 TAM7 air handler. See below.

7117217 Active Systems TRANE XL18I TRANE 4TWX8036C1 *AM7A0C42H31 1185 945 37000 13.00 18.00 31400 9.50 20200 1 HRCU-A-CB 255 627 Yes

A nice system, not cheap, better than any Amana. I assume a 10 KW heat strip. You already have a filter box cabinet?

I would want a new refrigerant lineset.

Nothing wrong with the XL15i either.

IMO

Yes, I have zoning system. and yes zoning control board was replaced with newer model not even 6 month ago. I do have two thermostat digital (Honeywell) they are not programmable.

I don't know what is filter box cabinet is but I can tell you I don't put or replace any filter in Attic where I have air handle now.

Today another guy came to my house to give me quote and actually took his time to see where is a leak in coil and it pretty bad leak where it is very hard to replace. He said it is worth to replace the unit.

He is going to give me quote on 15 SEER Temstar unit. He suggested not to put 2 Stage unit with zoning system because I may not get enough heating and cooling from it.

He said 15 SEER tempstar complete split system will cost me little over 5k for installation. He is using same copper line too.

You don't offer a model number on the Tempstar system components.

Don't kid yourself, Tempstar is not even close to Trane. It does not have electronic demand defrost, only the time/temp defrost method.

Get a price on Trane's XR15, make the comparison, and then your decision.

One system is a BMW, the other maybe a Dodge. Live and learn.

IMO

tempstar 3 Ton 15 SEER Main Line
TXH536GKA
FXM4X3600AT

10 Year Parts 5 Year No Hassle Warranty.

Installed price 4,884.00

I can not find an AHRI matching number for the models you listed.
I suggest you ask dealer for the matching number.

I would want to see a comparable quote on Trane XR15 or AmStd Heritage 15.

I suspect the price is much better than the HVAC.

IMO

ok i think this us best quote I got so far please help me to make decission.

option 1

3 ton
TRANE XL 18
tam7a0b30h21
bayevac08lg1aa (heat strip)
4TW8036A1 (out door unit model)

$6900

second option
3 Ton
Trane xL 15
4twx5036b1 (out door unit model)

everything is same as option 1

$6000

What are you looking for?

The XL18i system is a two stage system, the XL15i system is single stage.

The selection of the size of the air handler is very important for best performance/efficiency numbers.

4655313 Active Systems XL15I WEATHERTRON TRANE 4TWX5036B1 *AM7A0C36H31 1225 37600 12.50 15.00 34600 9.25 21800 1 HRCU-A-CB Yes 311 751 Yes

TAM7 36 size for the 3 ton XL15i system.

7117217 Active Systems TRANE XL18I TRANE 4TWX8036C1 *AM7A0C42H31 1185 945 37000 13.00 18.00 31400 9.50 20200 1 HRCU-A-CB 255 627 Yes

TAM7 42 size for the 3 ton XL18i system.

If this is not a budget decision, then get the XL18i system as I listed with 10 KW heat strip. Pay attention to the air handler model/size. If you are able to interpret the AhRI numbers, you can readily see there are some marginal savings with the XL18i system on cooling and good savings on heating with the higher HSPF efficiency.

You are getting some very good pricing.

I am done here.

IMO
Good Luck

Thanks for your input tigrdune.

Please explain me in simple english because I don't understand AhRI number.

I want to know what is the difference between these two air handler model number.

TAM7A0B30H21

TAM7A0C36H31

Why one guys quoting upper and other guys quoted bottom model. I did little search I think upper is 2 1/2 ton and bottom one is 3 ton but help me to understand what is the major difference and which one should i get.

I want TRANE XL 15i

The coil size determines the best performance(BTUs) and efficiency(SEER, EER, HSPF) in both cooling and heating mode.

If you don't follow my advice on the air handler model size, you are just cheating a nice system and your pocketbook.

Cost difference would be negligible to inconsequential compared to operating costs.

How much hand holding do you require?

While the XL15i is a very nice Sgl stage system, I would opt for the XL18i both on comfort and the higher HSPF which has a good payback in heating mode. You have received excellent pricing. I will assume dealer has determined operational compatibility of either system with your zoning system.

I am done here. Can't say anymore.

It bothers me that people come on this forum wanting advice but have a difficult time accepting it.

Go to AhRI site and get educated.

Tigrdune, I can not thank you enough for referening me to go to www.ahridirectory.org

This website is really nice if you want to compare different unit.

Thanks

Tigerdunes! Great advice, you seem to be very educated on the topic. But saying how much hand holding is required was very rude. It's very difficult to make a decision on what to select when each quote is very different and everyone try to use system terminology to make it sounds good, knowing you have no ideal what they are talking about

gkang2002, which company gave you the best price and how has the Trane system worked out for you. I live in Raleigh and need to replace an upstairs unit. Thanks.
