Again I suggest a load calc (manual J), then check your duct work to make sure it is designed for the correct amount of airflow (rm. by rm.), then check for leakage ( no point in having a $$$$SEER unit delivering conditioned air to your crawl or attic space). Posted efficiencies from the manuf. are based on specific coil combinations that have an ARI rating. A new "15 SEER" unit on your old coil and AH or Furnace is not "15 seer".

I only bought this house 5 weeks ago so I do not know anything about how well the house was heated and cooled. I have spent significant time caulking the numerous air leaks and plan on adding r-19 attic insulation in the next month. I am fond of no particular brand.
And quality of the install is paramount. Brand identification betrays more consumers than anything else.
DON'T DO BUSINESS WITH ANYONE WHO WON'T PROVIDE A MANUAL J BASED LOAD CALC. START FROM THERE...............
