Hi,this is my first post. I researched this forum for a few hours and was hoping some of you good people could answer a few questions for me.
First, I too was one of those people who was going to ask which furnace is the best. After reading several threads here, I've discovered that it's all about the installation. If you have a good installer, he could make almost anything work.
As far as my question and I hope I don't have this mixed up. I'm lookig at Bryant's Evolution line (same as Carriers Infinity line). They have the 90i and the 80v. Both are two stage variables. My understanding with variable furnaces (I may be wrong) is that they use a mechanical filter box. The heat is sucked back in through the intakes (I have one upstairs and one down stairs) and filterd through the box. This helps eliminate some of the germs and allergens in the house. I'm guessing that it won't work in the bedrooms upstairs since I don't have any
separate intakes inside the house. Then the heat is returned and distrubted evenly in the house. I'm told that I can also save around $150 on my electric bill a year with a variable speed furnace because it runs on DC power instead of AC power (It will run constantly).
Is this a gimmick or does it really work. I could just go with a plain Bryant 80t which is a two stage furance. Any input is greatly appreciated. I've learned a lot just in this forum and am still learing. Ultimately, I may have to decide if I want to get a 90% Bryant furance which is $1300 more than the 80v. Thanks
