Professional Heating & Cooling Load Calculation That Saves Energy & Boosts Performance
Ensure year-round comfort with our precise HVAC load calculations. We use trusted tools like HAP and AutoCAD to design efficient systems that reduce energy bills and improve indoor air quality. Serving clients across the USA, UK, Canada, and Australia, our expert team delivers tailored solutions for homes, offices, and industrial spaces.
We are specialist in:
We leverage advanced tools and software to deliver data-driven HVAC system design. Our expertise covers:
AutoCAD for precise drafting
HAP (Hourly Analysis Program)
Revit MEP for BIM integration
Carrier load analysis tool.
These platforms ensure our HVAC layout plans meet ASHRAE, SMACNA, and local code standards in all service regions.
Home comfort starts with properly sized systems. We assess building orientation, insulation, windows, occupancy, and local weather to provide:
- Room-by-room load analysis
- Duct sizing and airflow distribution
- Equipment selection support
- Integration with smart home HVAC setups
You’ll receive a detailed report with BTU requirements per room, peak load data, and energy-saving recommendations.
For offices, malls, schools, and public spaces, HVAC load design must be precise and scalable. Our commercial load calculations include:
- Variable occupancy modeling
- Internal heat gains (people, lighting, equipment)
- Fresh air ventilation loads
- Humidity control
- Zone-based temperature control
We produce accurate models that support HVAC zoning, load scheduling, and building automation systems.
We calculate:
- High ceiling and open space volume loads
- Heat gain from machinery
- Exhaust and ventilation loads
- Thermal zoning for warehouse and manufacturing are
Our data-backed approach ensures reliable climate control in complex environments.
Updating an old HVAC system?
We assess:
- New building envelope performance
- Updated occupancy and usage
- Window/door changes
- Ventilation and code upgrades
This prevents overspending on oversized HVAC units and helps meet modern energy codes.

FAQs
What is a heating and cooling load calculation?
A heating and cooling load calculation is a detailed analysis that determines how much heating or cooling a building needs to maintain a comfortable indoor temperature. It considers factors like climate, building materials, insulation, windows, orientation, and occupancy. Accurate load calculations prevent HVAC systems from being oversized or undersized.
Why is an accurate HVAC load calculation important?
An accurate HVAC load calculation ensures your system is properly sized. Oversized systems waste energy and money, while undersized ones can’t maintain comfort. A precise load calculation reduces energy bills, prevents system wear, and improves indoor air quality.
Which software do you use for HVAC load calculations?
We primarily use HAP (Hourly Analysis Program) for load calculations. We also use Trace 700, Revit MEP, and EnergyPlus depending on project needs. Our HVAC designs are created with AutoCAD and fully integrated with plumbing schematic diagrams, hot and cold water layouts, and more.
Do I need a load calculation for an existing building?
Yes. Even for retrofits or HVAC replacements, a new load calculation is essential. Building usage, insulation, and internal loads often change over time. A fresh calculation helps ensure energy efficiency and system longevity.
Can you integrate plumbing designs into HVAC plans?
Absolutely. We offer plumbing CAD drawings, plumbing riser diagrams, and plumbing schematic diagrams that align with your HVAC layout. We also design hot and cold water layouts and french drain diagrams when required, ensuring seamless coordination between systems.
Is your service compliant with local building codes?
Yes. We follow all major international and local standards:
USA: ASHRAE, IMC, IECC, SMACNA
UK: CIBSE & Part L
Canada: CSA B52 & NBC
Australia: AS/NZS 3666 & NCC
Our HVAC load calculations and mechanical plans are always code-compliant.
How long does it take to receive the load calculation report?
Delivery time depends on project size and complexity. For residential projects, it usually takes 2–3 business days. For commercial or industrial systems, it may take 5–7 business days. We also offer express delivery for urgent projects.
What types of buildings do you work on?
We work on all types of buildings, including:
Residential homes & apartments
Commercial offices & retail shops
Hospitals, schools & hotels
Warehouses & factories
No project is too small or too large—we tailor every HVAC design to your space and usage.
