HVAC Estimating Softwarefor Indianapolis Contractors
If you're bidding hvac in Indianapolis, 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 tornado and severe thunderstorm risk. Drop a plan set in, walk away for 15 minutes, come back to a priced bid you can defend.
What Indianapolis does to a hvac bid
Extreme temperature swings, cold winters, hot summers, tornado risk. Temperatures swing 0°F - 95°F, rainfall runs 30-40 inches, and inspectors here are working off IRC R301.2 / IECC Zone 5. 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.

Stuff Indianapolis hvac contractors ask before they sign up
Does this respect IN code, or do I have to re-cut every quantity?
Counts assume IRC R301.2 / IECC Zone 5 (frost depth 42 in., Class 4 impact-resistant shingles on most insurers, R-49 attic). IN 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.
How do you handle manual load calculations take forever?
The model reads the plan once, counts symbols against your assembly library, and surfaces the count for review. You override anything that looks off before it hits the quote. For industrial work in Indianapolis, the typical correction is one or two assemblies — not redoing the whole thing.
What about tornado and severe thunderstorm risk?
Need efficient heating AND cooling. Heat pumps with gas backup common. Zoned systems for large homes. Whole-house humidifiers in winter.
