Need help on which system to install
I am looking to replace two 25 year old air conditioning systems. I have received two very comparable bids using different equipment. One bid is using an American Standard Model 4A7A3030G1000A 13.00 Seer 2.5 ton condenser, with an American Standard Model TAM4A0A30S21SC Air Handler, and a BAYWAAA05SC1AA Hydronic Coil. The other bid is using a Trane Model 4TTB3030G1000A XB-13 13.00 Seer 2.5 ton Condenser, with an ADP Model BCRMB6636S3N3 3 Ton 13.00 Seer TXV Nonbleed 120V3 Row 3 Speed Air Handler w/66K Coil. I also have a 3 ton unit to replace using similar equipment. Both contractors also priced upgrading to 16 Seer units. The American Standard contractor's price to upgrade to 16 Seer units was actually a little less than the rebate I could receive from the utility company, so that's a no brainer. The Trane contractor's price to upgrade to 16 Seer units was about twice as much as the rebate I would receive, so that's a tougher decision. I am leaning towards the American Standard units. I did a little research and found the Trane XB-13 was their low end unit, but still good. I am not at all familiar with the American Standard units. Another issue I have is that I need to have a 110 volt air handler, which is why the Trane contractor went with an ADP air handler. Is the American Standard Air Handler listed above compatible with 110 volts? Any input or help would be greatly appreciated.
