Why do prices vary so much? Here's what affects how much you'll pay.
Larger homes have more rooms, windows, and surfaces to analyze. Some providers charge more for homes over 3,000 sq ft.
Multi-zone systems require separate calculations for each zone, increasing complexity and cost.
Rush jobs cost more. Standard 24-48 hour turnaround is cheaper than same-day service.
Block load calculations are cheaper than full room-by-room analysis with duct design.
Online services are cheaper than local contractors who may include on-site visits.
Costs vary by region. Major metros often have higher rates than rural areas.
The ROI of proper HVAC sizing is enormous

CoolCalc charges $5-15 per report depending on volume. They offer discount packs for multiple calculations. However, it requires manual data entry which takes 30+ minutes per calculation.
Wrightsoft starts around $200/month for their HVAC design software suite. They're the industry standard for large firms but require significant training to use effectively.
