We installed Harvey double hungs in our living room and bedrooms about two years ago and have been happy with them. The harvey double hung windows price https://ubrothersconstruction.com/catalog/windows/double-and-single-hung/item/harvey-classic-vinyl-double-hung-window was in the mid-range compared to other brands. What stood out to us was the ease of cleaning—tilt-in sashes make a big difference. Plus, the vinyl frames haven’t warped or discolored, which had happened with a cheaper brand we previously used. Sound insulation improved dramatically too; we live near a busy street and it’s noticeably quieter inside now. If you're planning to stay in the house long-term, I'd say they're a worthwhile investment.
