This was a solid, practical HVAC rundown—especially the parts about proper sizing, duct sealing, and not ignoring the house envelope. I liked that it didn’t just push new equipment and actually emphasized maintenance and airflow/refrigerant checks. A couple quick rules-of-thumb or example thermostat setpoints would make it even easier to apply, but overall it’s a helpful guide.
This guide does a solid job explaining that efficiency isn’t just about buying a newer unit—it’s sizing, controls, and fixing the house first. The sections on duct leaks and basic maintenance (filters/coils/refrigerant charge) were especially practical and easy to follow. I would’ve liked a quick checklist or rough “biggest impact” order at the end, but overall it’s a useful, no-nonsense overview.
