Why do you need Briant or carrier.There are alot of good products out
there, some better. The instaler is the most important part of any
install. A good instaler will take average equipment and and do it right
making you comfortable and efficient, an unexperianced tech can make it
the oposite, and you will never be happy. Buy an instaler not a name
brand, look for a pro not a student who will make his mistakes while you
pay for him to do it.
