Bryant (owned by Carrier) only sells their product to Bryant dealers. If you're looking to DIY the install, you'll have to find a brand that can be bought online, such as Goodman.
Nobody does. If you're DIYing this, your options are limited as far as brands. You'll need to do your homework. Find out what brands you can get, then research those to see what is best for you. Proper installation is key, so you'll need to know that you're installing it properly. There's more to it than just connecting the ducts, gas and electric. You could have the best furnace on the market, but if the install is subpar, you will have problems.gjones said:Are they worth buying? I don't want to spend the money to buy something that will cause problems.
