Dear hvac-talk man,

I want to sell my condo, (more like need to as I have been laid off), but it will speed up the sale if I replace the old-troublesome HVAC system. My one-floor condo is in Mass. And is 945 sq.ft. with 5 windows. The quote is for $7,360, and I trust the guys who made the proposal. I am going to get a quote from Sears on a Carrier and another private HVAC co. (don't know the make they will quote.) I am thinking about asking Home Depot to give me a quote too. Do you have an opinion about Sears, Home Depot, Trane and Carrier, and do you think the$7,360 is a good price for the Trane that I mentioned above?
