HVAC Load Calculation & Design Services

What Are HVAC Load Calculations?
HVAC load calculations are the essential first step in designing an efficient heating and cooling system. These calculations determine exactly how much heating and cooling capacity your building requires based on multiple factors including size, layout, insulation, windows, climate zone, and occupancy patterns.
Proper load calculations prevent the common and costly problems of oversized or undersized equipment. An oversized system cycles on and off too frequently, wasting energy and creating uncomfortable temperature swings.
At Consac, we perform comprehensive calculations following ACCA (Air Conditioning Contractors of America) standards, including:
Benefits of Accurate HVAC Design
Investing in professional HVAC load calculation and design services delivers significant returns through improved comfort, efficiency, and system longevity. Here's how proper HVAC design benefits your project:

Energy Efficiency
Properly sized systems use up to 40% less energy than oversized units, significantly reducing utility bills and environmental impact.

Enhanced Comfort
Eliminate hot and cold spots with balanced airflow and proper temperature control throughout your entire space.

Extended Equipment Life
Correctly sized systems experience less wear and tear, reducing maintenance costs and extending equipment lifespan by 5-10 years.
Code Compliance
Meet building code requirements and avoid permit delays with professionally prepared documentation that satisfies local authorities.
Humidity Control
Maintain optimal humidity levels to prevent mold growth, protect building materials, and improve indoor air quality.
