I will carrier hap hourly analysis program hvac load calculation

If you just need a rough tonnage guess for a quick job, skip this cheaper, faster gigs exist for that. But if you're sizing equipment for a commercial or multi-zone building and can't afford a load calc that falls apart at plan review, keep reading.

I run precise HVAC load calculations in Carrier HAP (Hourly Analysis Program) accounting for occupancy schedules, ventilation rates, envelope construction, and equipment profiles, not a simplified block estimate. This is the tool engineers actually use for commercial-grade accuracy.

What you get: zone-by-zone load breakdown, equipment sizing recommendations, and a report built to hold up under contractor, engineer, or plan reviewer scrutiny.

Who this is for: mechanical engineers, contractors, and consultants working on commercial, multi-zone, or mixed-use buildings.

Who this is NOT for: single-room quick estimates see my Cool Calc Manual J gig for that instead.

If your project needs real commercial load accuracy, send me your building details. If not, no hard feelings good luck with your project.
