Trane or Carrier?

Hi all - I am just outside of Boston MA so the spring, summer, winter up here can be brutal depending on the year. Our new home which we've completely renovated does not have a central AC system. I have gotten a few quotes and have settled between two options. Trane or Carrier...here is the model info

Trane option 1:
Trane 4TTX8024A1000B - XL18i - 18 SEER
Trane TAM9A0A24V21DA

Trane option 2:
Trane 4TTX6024J1000B - XL16i - 16 SEER
Trane GAM5B0A24M21EA

Carrier option:
Condenser: Model-24ABC636 - 15 SEER
Airhandler: FX4DNF037

I am only cooling my main level which includes 3 bedrooms, a bathroom, and then a wide open kitchen, living room, dining room. Total SF for main level I would say is 1700...total house is 2150.

Between the two Trane systems is only a $1600 difference and between the Trane option 2 and Carrier is about 2k which means its about 3500 from the Trane option 1.

I have done a little research, but honestly not sure what would be the best option...I do have a high efficiency boiler I put in a year and a half ago and I have 2 Ecobee thermostats.

Would love some information! Thank you in advance

Trane option 2 or Carrier. You will never see the savings for the 18 SEER in your area. Personally Id recommend a 4TWR5024H WITH A TEM6A0B24 ahu. This gives you 15 SEER with a variable speed metal AHU.

Thanks, thats pretty good info. Honestly, the company that sells the Trane I am more sold on them as a company and what they offer and we really hit it off and I would much rather use them, but he can price me out any Trane system. I should mention that I am using part of this thing called a mass save loan for part of the AC so it needs to meet these requirements

>16 SEER and >13 EER greater than or equal to.

Those numbers I posted were for a heat pump. Id get the metal AHU. IMO its better, TEM is the metal framed.

If you have a boiler then no real need for a heat pump. Stick with the AC witch will be the 4TTX the TEM AHU should be cheaper and not made out of plastic.

I put in a Utica high efficiency boiler and my guy was able to get it to 98% efficiency and its been working wonders. Have had it for a year and a half almost 2 years now. So, you think xl16i with a TEM AHU? I just tell them that?

I asked about a variable ahu on the xl16i and this was the installers response...The air handler I gave you on the proposal is ECM driven and it's a high efficiency unit. I can give you a variable speed air handler at an addition cost of around $400 if that's what you'd like.

Anyone have any other thoughts on this?

I have the installer who quoted me the system coming back July 2nd to go over the options a bit more.
