I will do thermal load and heat loss calculations for hvac sizing
About this Gig
Struggling to size your HVAC system correctly? Wrong load calculations lead to oversized equipment, wasted energy, and uncomfortable spaces. I provide accurate thermal load and heat loss calculations that give you the exact numbers you need to size HVAC equipment with confidence.
What I calculate:
- Heat loss and heat gain (BTU/hr or kW)
- Room by room load breakdown
- Envelope losses (walls, roof, windows, floors)
- Infiltration and ventilation loads
- Design temperature analysis based on your location
Using Manual J and ASHRAE based methods, I deliver clean, submission ready reports that contractors, engineers, and permit offices can rely on. Whether you're a homeowner, contractor, or HVAC installer, you'll get precise numbers not guesswork.
Send me your building plans, dimensions, or specs, and I'll turn them into a clear, professional load calculation report fast.
Message me before ordering if your project has unique requirements I'm happy to scope it out first.

Building dimensions or floor plans, location (for design temperature data), insulation/wall assembly details, and window/door specs. I'll guide you if you're unsure what to send.
Can you use my existing floor plans or CAD files?
Yes, I can work from PDF, CAD, or hand-drawn plans as long as dimensions are legible.
Do you follow Manual J or ASHRAE standards?
Yes, calculations follow Manual J (residential) or ASHRAE Fundamentals (commercial), depending on your project type.
Will this report be accepted for permits?
Yes, reports are formatted to be submission-ready. However, some jurisdictions may require a stamped/sealed report from a licensed engineer in their state let me know if that applies to you.
