Fast Estimate vs. ServiceTitan
Built by Scott Herberg, 28 years in HVAC. Not a generalist app that added HVAC as a category.
Looking for a ServiceTitan alternative built for small HVAC shops?
ServiceTitan is a powerful platform — for operations running 20+ technicians with office staff to manage it. If you're a solo operator or small crew that just needs professional estimates out the door fast, you don't need weeks of implementation. You need a photo, two minutes, and a signed PDF.
Where the real difference shows up: total cost of ownership
ServiceTitan pricing is quote-based, but industry surveys consistently put it in the hundreds of dollars per technician per month, plus onboarding fees that can run into the thousands. That math works when the software is managing twenty trucks, a call center and a marketing budget. For a three-truck shop, the same line item buys a lot of features that never get opened. Fast Estimate charges a flat $99.99 a month for the whole company — the trade-off is scope: it does estimating, signatures, deposits, invoicing and job scheduling, and deliberately nothing else.
The second difference is time-to-value. ServiceTitan implementations are measured in weeks and involve data migration specialists and training sessions — reasonable for an enterprise rollout, painful for a shop that needed quotes out the door yesterday. Fast Estimate is self-serve: contractors typically send their first signed estimate the same afternoon they create an account. If your bottleneck is quoting speed rather than dispatch coordination, that is really the whole decision.

Fast Estimate
The pitch: Snap a photo of the unit, describe the job, and get a branded, line-itemized PDF estimate with e-signature and deposit collection — in under two minutes, built by Scott Herberg, 28 years in HVAC.
Pros
- Purpose-built for HVAC replacement and service work — not a side category in a 50-trade platform
- AI reads the photos and proposes equipment, labor, and parts pricing automatically
- AI vision actually inspects your photos — flagging rust, corrosion, sizing, access, and electrical issues — and writes a customer-facing site assessment right onto the estimate
- The customer sees their own unit: job photos are attached to the estimate and the branded PDF, right next to the AI assessment — a powerful trust and close booster
- E-signature, deposits, and branded PDF export included on every account
- Mobile-first — designed to be used standing in the driveway, not at a desk
- No bloated FSM you don't need if all you want is fast, accurate estimates
Cons
- Not a full field service management platform — no dispatch, scheduling, or job costing module (by design)
- Newer platform without the years of reviews larger competitors have
ServiceTitan
The pitch: The enterprise-grade field service operating system for large HVAC and trade businesses.
Pros
- Extremely deep functionality — pricebook integration, real-time job costing, AIA billing, full procurement-to-cash workflow
- Built for complex commercial and large residential operations
- Industry-leading for 20+ technician shops
Cons
- Explicitly not built for businesses with 3 or fewer technicians
- Requires dedicated office staff to manage its complexity
- Significant implementation time and cost — not a same-day setup
Which one fits your shop?

- You want to be sending signed, branded estimates the same afternoon you sign up
Switching takes an afternoon, not a quarter
- 1 Create your account and upload your logo, license number and terms — about five minutes

- 3 Quote your next call with the photo flow and send it for e-signature before you leave the driveway
Fast Estimate vs. ServiceTitan — common questions
Is Fast Estimate a full ServiceTitan replacement?
No — and it doesn't try to be. Fast Estimate focuses on estimating: AI-drafted line items, branded PDFs, e-signatures, deposits and follow-ups. It doesn't do dispatch, payroll or marketing attribution. If those are why you pay for ServiceTitan, keep them; many small shops simply never needed them.
How long does setup take compared to ServiceTitan?
Most contractors send their first estimate the same day they sign up. Add your company details, optionally import your price book CSV, and the AI is ready — there's no implementation team or training program because there's nothing complicated to learn.
Can my whole crew use it?
Yes. The flat $99.99/month plan includes unlimited technician seats, so every tech can quote from their phone and every install can be assigned to a crew member on the job calendar.
