The top floor of my house (~100 years old) is a complete sauna. I'm starting by looking at replacing the windows but it's a minefield. Renewal by Andersen are twice the price but seem like the Apple of windows (but are they?). Others have scary used-car-salesman hard sells. One didn't know that a divider was load-bearing, which would have been catastrophic. It's an expensive minefield - and that's before I look at mini-splits etc.
@ben My impression is that Renewal by Anderson is mostly salespeople. Who the actual contractors that do the work are is key. We were able to just replace the glass panes with a local company (but our issue was failed double glass seal). But for heat issues, why start with the actual windows? What do you have for attic insulation and ventilation? The quick right now solution for windows would be heavy blackout drapes.
