I have a 2 zone HVAC system in my home. We primarily stay in Zone 1 (downstairs) and marginally use Zone 2,(upstairs, office and spare bedrooms). Is it beneficial to have zone 2 AC on, say set to 80 to help keep the entire house cool during these hot winter months? There are also attic fans installed. This is my first experience with 2 zone HVAC. Any comments would be greatly appreciated Thanks, Ed
