I'm thinking of replacing the AC unit in my 2 story home.

Customer Question

I'm thinking of replacing the AC unit in my 2 story home. It's 17 years old now and while it works, I think I'm pushing it by not replacing it. I want to know what brands I should stick with, how much I should expect to pay, what I should look for in a contractor, how many seer, how many btu, should I replace the whole unit or just part of it, should I replace my ducts because they are flexible ducts and I believe them to be inefficient at allowing air flow. I also have an issue with one of the rooms on the second floor getting hotter than the rest of the house. How would I have that fixed?

OK as a rule of thumb the equipment will be about 1500 to 2000 per ton depending on seer rating.If you can provide model on your outdoor I will tell you how many tons it is.

AS for SEER rating, the more you can afford to spend up front on installation the more you can save on utilities.Can you get me that model on outdoor unit?
