From my 33 years as a home owner, I have made an observation that I am more than comfortable with. Since I shouldn't use filthy language I will dress my comments up. I didn't read all of the previous post so I may\be saying something someone else did.
Clearing my throat. I personally don't give a rat's anus about the brand of HVAC anymore. I used to care, but not any more. If your HVAC company doesn't know stink about how to properly design and install your system it won't matter how great the brand of unit you are installing. Trane, Goodman, Lennox, American Standard, Rheem, Carrier, etc, etc, etc. Forget that Super HI efficiency mumbo jumbo. If they have a poor reputation for service it really won't matter what brand you buy.
You MUST find the very best HVAC company in your area. Ask around. Do your research. Find out which companies will quickly service what they sell, how long have they been in business. Ask your coworkers and neighbors.
Look for the company first and then let that company help you pick one of the units they sell. Unit selection must come after you pick your HVAC company. Trust me. You want to establish a relationship for the long haul.
I promise this advice will pay off much more than the brand of unit you get. I promise. Pick a HVAC company with the best reputation in your area before you even consider the brand of HVAC. And don't worry too much about the price. Be concerned, but not overly concerned.
A shady, sheetie company will probably install a super unit that won't work like it should. A reputable HVAC company can make a sheetie unit operate like a Rolex. Well, maybe not a Rolex. You know what I mean...hyberbole.
