Original Request Description

I’m trying to sanity-check a small B2B SaaS idea before I sink more time into it. The product would be a simple web/mobile tool for independent commercial HVAC contractors with 5-50 techs: job photos, field notes, quote follow-ups, and a lightweight customer handoff log that sits between text messages and a full FSM system. I do not need a full business plan, just a reality check on whether this niche is big enough to support a paid product. Please estimate the likely buyer pool in the US, rough TAM/SAM/SOM, realistic price bands, and the main competitors or substitutes people already use. If you think the market is too small, say why and point to the closest adjacent niches that would be larger. A good answer should include a short assumptions table, the key data points you used, and a blunt conclusion on whether this is worth pursuing.

Short recommendation: pursue this as a narrow paid niche, not as a broad FSM platform. The buyer pool is real, but the standalone market for independent commercial HVAC shops with 5-50 techs looks like a roughly $20M-$56M ARR opportunity, not a giant category.
| Assumption | Base case | Why I used it |
|---|---:|---|
| U.S. HVAC tech jobs | 425,200 | BLS OOH, 2024 employment |
| Share at plumbing/heating/air-conditioning contractors | 70% | BLS says this is the largest employer for the occupation |
| Employer HVAC contractor firms | 92,572 | Census-based count summarized by PM Magazine |
| 5-49 employee firms | ~32,500 | 2015 Census size-shape proxy: 5-9 = 17,788, 10-19 = 10,834, 20-99 = 7,853; I split 20-99 roughly in half to approximate 20-49 |
| Commercial/mixed share of 5-49 firms | 25% | Directional haircut because commercial specialists skew larger and most contractors are not majority-commercial |
| List price | $29-$49 per tech/month | Anchored to Jobber, Housecall Pro, and ServiceTitan pricing signals |
| Option | Price signal | What it already covers | Why it matters |
|---|---|---|---|
| ServiceTitan | Per-tech, quote-based | Full FSM, dispatch, pricebook, memberships, reporting, customer portal | It is the obvious upper-end incumbent if the shop outgrows a lightweight tool. ServiceTitan pricing |
| Housecall Pro | From $59/mo | Quotes, scheduling, job details, photos, attachments, invoicing, follow-ups | Strong SMB default; broad enough to swallow a generic photo+notes workflow. Housecall Pro pricing |
| Jobber | Plans start at $29/mo; users add $29/mo each | Scheduling, job details/photos, quoting, automated follow-ups, invoicing, payments | Good horizontal substitute for small teams; pricing is low enough to block a thin wedge. Jobber pricing |
