Homeowners struggle to determine correct HVAC system size for their homes, leading to inefficient cooling/heating and wasted money

Homeowners in cold climates like Rochester, NY don't know what size HVAC system they actually need, resulting in either undersized systems that can't maintain comfort or oversized systems that waste energy and money. Current solutions fail because homeowners lack technical knowledge to calculate proper sizing based on square footage, insulation, and climate zone, forcing them to rely on contractors who may upsell unnecessarily large systems for higher profits.
