I will manual j hvac load calculation heating cooling loads calculations
About this Gig
Get accurate heating and cooling load calculations using the ACCA-approved Manual J methodology. Whether you're a builder needing permit documentation, a contractor sizing equipment, or a homeowner planning a new HVAC system, I deliver precise load calculations that ensure your system is neither oversized nor undersized.
Oversized systems short-cycle, waste energy, and fail to dehumidify properly. Undersized systems can't keep up during extreme weather. A correct Manual J calculation is the foundation of a comfortable, efficient home.
What's included:
- Complete heating load calculation (BTU/hr)
- Complete cooling load calculation (BTU/hr, sensible + latent)
- Climate-adjusted design conditions for your location
- Envelope analysis (walls, windows, roof, foundation)
- Internal gains and infiltration accounting
- Professional PDF report suitable for permitting

FAQ
What information do you need from me?
Architectural plans/floor plans, insulation R-values, window specs, building location, and orientation if available.
Will this pass permit review?
Reports are prepared following ACCA Manual J standards accepted by most jurisdictions, but please confirm specific local requirements with your building department.
Do you provide equipment recommendations?
Yes, general sizing guidance is included; detailed Manual S equipment selection is available as an add-on.
What's the difference between heating load and cooling load?
Heating load determines the BTU/hr needed to maintain indoor temperature during the coldest design day; cooling load accounts for both sensible heat and latent (humidity) loads during peak summer conditions. Both are calculated in this gig.
