All 3 are moderate to low systems based on price.
The system brand isn't the important thing. The most important thing is the correct installation of the system you chose. Quality costs money. So don't go with the lowest bid. Otherwise you will get the lowest quality.
My advice is simple. Get several quotes from several companies. Do backround research on the companies. Check BBB and prior customers. Assure they are doing a load calc., sizing the ductwork, and designing the ductwork for proper and balanced air distribution.
Get the extended warranty to include parts and labor for 10 years. Get a service contract. Get the highest efficiency system you can possibly afford. Get a system with R-410A refrigerant.
HVAC is not an expense. It is an investment. Invest wisely now and you won't be sorry later. Invest poorly now and you'll regret it before you know it.
I fully support the military and the War on Terrorism.
If you don't know, then don't do. If you don't know and still do, then be prepared to pay someone else a lot to undo what you did and then do it right.
If you do know, then do. But do it right. Otherwise, you may not be doing it long.
