I enjoy reading the forums and am now very confused. We have lived in the house one year
I have had two Trane dealers come out and neither sales person has done any calculations, they just measure the old furnace size and ask a few general questions.
Our house has the original furnace and I believe the original home owners added an addition (family room) to the house 20ftX30ft.
I have read over and over that it is not the equipment, but the contractor that you choose that makes the difference. Thanks for that! I must be a product of marketing........
I read that the 90+ efficiency gas furnaces require air intake/exhaust to the outside of the house. I also read that this helps bring in fresh/cleaner air. My wife is an asthmatic, but she won't get ride of the 2 dogs.... I have also read many posts on the air quality issue and I am thinking an expensive filter system would not be worth it with the dogs and many people feel they don't work that well.
I have a couple of questions:
I like the idea of the fresh air from outside, and I think I read that this helps the house because it creates a pressure outward instead of inward with a standard system. Is this true or did I misunderstand the posts?
Also why are these sales people not doing a manual J calulation that determines the right size furnace and A/C unit?
I am not sure how long we will live in the house and when it comes to resale the high efficiency furnace might give us an advantage over other houses that would be for sale.
The features like the filter systems and humidifier are now very low on my list. Our house is about 2000 sq.ft and I am a single income person. When I got a quote in the $9k range for an 80% variable speed trane and a 13 seer AC unit with the Trane Aircleaner system and humidifier I almost had a heart attack (just kidding).
So my thoughts are now to keep looking. A dealer with 15-30 years in the business and does not need to do calculations I should steer clear.
Is there any systems I should steer clear of due to reliability issues?
also the ac units have been the R22. Is this a problem? Or is it ok and the summers are warm in Chicago, but not overly hot as we have spent the past 16 years in Florida. Cold Yes hot No!
