Preferred AC brand??

Is there a preferred AC brand?? I'm going to replace a Ruud split AC system in SW Florida with a 2T split system. It is going in the attic above living space so sound level is important.

What is the difference between a builders model and others, how do I tell?

Carrier, Trane and Lennox would be some good choices.
A 2 speed condenser and variable speed blower would improve humidity control.

Were you able to get your tonnage from that odd model number for your indoor unit?

The outdoor unit model number would be better. A flashlight held at an angle can sometimes help read a faded tag.

 

And remember...as all the Pro's say...the installing company is much more important than the specific brand. No.."Oh you have a 3 ton...so thats what we'll put in" or "Well I've installed plenty in these houses..here's what you need."

They need to do the calculations necessary to determine the right unit.

 

The outside unit has been painted a couple times so there is no getting numbers off it

It is more curiosity now, after much surfing the web, and this forum, and talking to 5 contractors. I have decided to do a Manual J. I had 3 recommend contractors here, one wanted to put in a Rube Goldberg replacement and use a 2 or 3 ton unit up to me?? Another told me the "rule of thumb" for this size and type of house is 1 Ton for 500 sq ft. So I need a 2 1/2 ton unit for 960 sq ft Only 1 of the 5 noticed that the present duct work is too small.

I truly appreciate the time and effort people on this forum put into your responses. I could have ended up with an expensive system that did not work well.
