HVAC Estimating Softwarefor Grand Rapids Contractors
If you're bidding hvac in Grand Rapids, 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 Grand Rapids 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.

Subbing under a licensed GC is one workaround, but on direct-to-owner jobs the homeowner can void the contract if you don't hold the card.

Stuff Grand Rapids hvac contractors ask before they sign up
Does this respect MI 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). The takeoff doesn't pull a permit for you — that's still on whoever holds the Mechanical Contractor License — but the assemblies match what MI inspectors look for.
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 manufacturing work in Grand Rapids, the typical correction is one or two assemblies — not redoing the whole thing.
What about tornado and severe thunderstorm risk?
