I live in New York, so we only get about 2-1/2 months of summer with usually only a week or two or three of hot/humid weather. I received estimates for two Lennox central air systems and would like to know which would be the one to go with: XC15-030 (2-1/2 ton) or XC21-036 (3 ton)
PMAC-12C/20C filter PCO-12U/20U Pure Air

The only calculation done by the salesman was Lennox's own cooling data sheet. The 2nd dealer also gave an estimate on these 2 Lennox systems only with slightly different components. I had wanted an estimate on Trane, but he said they use plastic tubing instead of copper and did the estimate on Lennox as follows:
XC15-036 (3 ton) or XC21-036 (3 ton)

He wouldn't do a manual - J as he says they take 3 hours to do, and he will only do it after we sign with him. Both dealers played around with the rebates. Also do I need to get the air filter or is this an option that is not necessarily needed. I wonder if the XC21 is overkill. I will also be getting an estimate on a Bryant system.Thanks for your help.
