Visual Heat Attic

Since heat naturally travels from hot to cold areas hot air will enter and leave a conditioned home through leaks and holes the largest of which are usually in the attic.

Visual heat attic.

Achieving greater r values in attics the higher the r value the better the thermal performance of the insulation. Attic hvac systems save space. Most updated central air conditioned homes have a new air conditioner split system meaning the ac is broken up into parts. So why put an hvac system up in the attic at all.

Visual inspection can go a long way to heading off these problems.
