HVAC Estimating Softwarefor Fort Collins Contractors
If you're bidding hvac in Fort Collins, the gap between a job that nets margin and one that doesn't usually comes down to undersizing equipment for actual load — and how you handle heavy snow loads on roofs. Drop a plan set in, walk away for 15 minutes, come back to a priced bid you can defend.
What Fort Collins does to a hvac bid
Cold winters, mild summers, significant snowfall, high UV. Temperatures swing 10°F - 85°F, rainfall runs 15-25 inches (plus heavy snow), and inspectors here are working off IRC R301.2 / IECC Zone 6–7. None of that shows up on a plan symbol legend — but it changes your fastener schedule, your waste factor, and whether the building department signs off on the rough.

CO doesn't license hvac at the state level, so the variability comes from local amendments. Quantities are correct; you adjust crew rates and local permit assumptions in the bid summary.
