Not for you if: you need dispatch, scheduling, or invoicing — this is estimating only. Not for shops running more than 10 techs. Not for trades other than HVAC.

Built for the field, not the office

AI line items

AI reads your photos and notes, then proposes equipment, labor and parts with real installed pricing.

Who built this

Fast Estimate was built by Scott Herberg, who has spent 28 years in HVAC — most of it as a manufacturer's rep in the Pacific Northwest, working with the contractors this is built for. The estimate flow follows how a replacement job actually gets quoted in the driveway, not how software people think it works.

Questions, answered

How does AI HVAC estimating work?

You pick the job type, add a few details, and snap photos of the unit. AI vision inspects the photos, flags rust, sizing and access issues, and drafts line-itemized equipment, labor and parts pricing you can review and adjust before sending.

How accurate is the AI pricing?

The AI proposes equipment, labor and parts with installed pricing, then you edit every line before it goes out. Nothing sends until you approve it. Most techs adjust two or three lines and send. Your own prices override the defaults and stick for next time.

Is this priced per seat?

No. Fast Estimate is one flat $99.99/month for your whole company — unlimited technicians, each with their own login. Adding a tech never changes your bill.

How fast can I really build an estimate?

Under two minutes for most jobs. Pick the job type, add a couple notes and photos, and the AI fills in the line items.

Do I need a credit card for the free trial?

No. Every account starts with a full-featured 7-day free trial — no credit card required. Subscribe for $99.99/month only if it's winning you jobs.

Can my whole team use it?

Yes. Add unlimited technicians, each with their own login, all sharing your company branding, templates and customer book — at no extra cost.

Do I need any technical skill?

None. If you can take a photo and tap a button, you can build a polished estimate.

What job types are supported?

AC replacement, furnace, mini-split, heat pump, ductwork and service calls.

Can I put my logo and company info on it?

Yes. Upload your logo and license in Settings and it shows up on every PDF and signing page.

Yes. Send them a link, they sign with their finger, and you get notified instantly.
