Help me decide on expensive HVAC and Mini split (Daikin or Carrier) Philadelphia, PA

[msoutdoor]

Situation: replacing 1985 HVAC system in a split house. The duct system is divided in two path (LEFT - living area, kitchen....) RIGHT (rooms) Total 1880 Sf.
Addition 13 x 14 no A/C or heat
Duct system on the RIGHT side path has a manual DAMPER. I need to keep it close half way in order to do not get toast in the bedrooms when the thermostat reach the temperature

The idea with the Zoning is to fix the toasting problem in the rooms.

My QUESTIONS
1- Please let me know what you think I should do if so far the DAIKIN cost is been offered 37% than the CARRIER.
2- If the Zoning is removed from the DAIKIN it is the same price as CARRIER.
3- IF I am able to negotiate the DAIKIN with Zoning at the same price as CARRIER what would you recommend?
4- Do you think I should get the Zoning system or keep using the manual damper that I already have?




Please let me know

If someone would wait for a reply in the posting system would get long time to get an answer. What a BAD community or service

Nice.

Most of us have full time jobs and can't reply to posts right away, good luck.

Having a full time job it is totally understandable. However the post was done on 5/20/16 and no one has even make any replies in 10 days? It seam to me odd that in this community no one has seen the post. For example look at the following post "Thread: Trane vs American Standard Comparison" done in HVAC TALK on 5/25/16 at 10:48pm. Some one started replying the 5/26/16 at 5:51 AM and it already got 8 replies even over the Holiday.

Now I kindly appreciate if you can still help me giving me 5min of you time to review my two proposal like you have done it with other post in HVAC Talk. It would really help me in taking a decision from a Professional HVAC person with an unbiased opinion I would greatly appreciated it since this is a really long time investment.

Question out of my league. Sorry

[lkapigian]

I would like to see a layout of home and duct system- Proper install and design is key--not enough is known about Daikin in the Resi World, but it is just a new name for Goodman-

Possibly this can be accomplished with 1 unit with zoning..........DONT YELL AT US

[ksefan]

I would do away with zoning unless you get a varible speed compressor system, like the carrier greenspeed.

^^^^What ksefan said^^^^ Green Speed is The Bomb......Lennox has a true VS as well, but not familiar with it

That is why the Honeywell 2 zone zoning system is included. Is that zoning good for the system quoted?

[msoutdoor]

Isn't Model 59TP6A080E17 with variable speed?

Any opinion on the 12 years warranty from Daikin compare to 10 Years from Carrier?

[rider77]

80,000 BTU for 1800 sq ft? How was this sized?
You posted in the wrong section, by the way

the fan is VS the compressor is 2 stage -That is my most common set up, but without putting eyes on a diagram and knowing the size of zones I would defer to Greenspeed which is VS AC/Heat ( compressor) and Fan

[msoutdoor]

What is your concern? Can you elaborate?
A J load calculation was done. Also we are installing a mini-split in the addition (13 f x 14 f) that is connected to the house but it does not has registers. It is also at the end run of one of the path for the LEFT side of duct work. For that reason it would also help.

Any idea on the Daikin product that I mentioned in order to compare with the Carrier?

[msoutdoor]

Where should I had posted it?
Please let me know to address the issue.

Thank you

Mike
