i am trying to change the existing air conditioner units that i have now (builder grade units). The ones that I have are 2 units - 10 seer weather king and luxaire. Contractor said that all he can offer me without having to change the whole duct system, which is very expensive is 13 seer R33 units. I wanted more expensive units, like Carrier infinity, but he said the whole system will need to be changed, which will be like xxxxx dollars. He is giving me a choice b/w Coleman Echelon, Trane, Carrier Comfort, and Lennox Elite. (all 13 seer). My MAIN concern i the noise, that's the prime reason I am buying new air conditioners in the first place. I need them to be as quiet as possible. Could you please recommend which one of those is the quietest one? I looked at the specs and the sound level of Coleman listed to be at 69db, comparing to others that are over 76db. But I still have my doubts. Would anybody please advise, maybe you heard coleman echelon is real life, how quiet is it?? I really need some help on this one, I need to make a decision pretty soon.
thank you very much
