Most field service software starts from the calendar or the customer account. Thermal starts from the equipment. The installed unit is the record, and agreements, PM visits and service history hang off it; coverage is written against the unit, not a customer name. Built for commercial and mechanical contractors; residential crews inside those shops are supported too. If you run 5 to 200 technicians across several trades and your revenue lives in service agreements on equipment you maintain, Thermal is built the way your work already runs, and switching cost is low: it imports price books from 11 named sources, there is no implementation project, and it runs month to month with no exit penalty.
This is an independent editorial review by Chip, based on Thermal’s public documentation rather than a hands-on trial. Thermal is built by Thermal Fieldserv Software Inc. of Nanoose Bay, BC, Canada.
Chip’s take
Thermal’s own line is that “Equipment is the centre of the spine. Everything hangs off the unit on purpose” (equipment). That is a real design choice, not a slogan. Age, warranty, refrigerant and every past visit live on one serialized unit, so a callback connects to a cause instead of starting over. Agreements follow the same rule: “Coverage is written against installed equipment, not against a customer name” (agreements).
For a commercial HVAC, mechanical or refrigeration shop, that is the right starting point. The work you sell is coverage on units; the work you dispatch is PM and repair on units; the history your customer asks for is the history of a unit. Thermal puts that record at the centre and builds dispatch, agreements and invoicing around it.
Who it is for
Commercial and mechanical service contractors “run more than one trade under one roof — HVAC, mechanical, refrigeration, fire & life safety, commercial plumbing” (industries), and that is Thermal’s buyer: a shop of 5 to 200 technicians, agreement- and asset-heavy, often multi-branch, that wants a modern, lightweight system without an implementation project.
The three things that set it apart
Equipment-first. The installed unit, not the job or the customer, is the record everything else hangs off. PM work orders generate from the agreement’s schedule, and service history, warranty and nameplate data travel with the equipment.
Multi-trade commercial shops. One system for a contractor running several trades across 5 to 200 technicians, with every branch in the same tenant rather than a second instance.
Low switching cost. Thermal imports price books from 11 named sources (ServiceTitan, Jobber, Housecall Pro, Service Fusion, FieldPulse, FieldEdge Flat Rate/Coolfront, Profit Rhino, The New Flat Rate, PricebookPlus, Allpriser, Callahan Roach) (integrations). There is no implementation project: you export what you have, stage it for review, and approve what moves (migration). There is no minimum term, it runs month to month, and there is no exit penalty (terms). If it doesn’t fit, you leave owing nothing. You can sign up for a self-serve trial.
What you get
The platform is one schema: customer, service site, equipment, agreement, work order and invoice, wired together. The live modules are Dispatch, Equipment, Preventive maintenance, Service agreements, Quoting, Invoicing, Customer portal, Subcontractors and Inventory. The Rentals and Job costing modules are early access.
Dispatch covers emergency work orders and multi-visit jobs on one board. Service agreements handle tiered agreements, escalations, MSAs, per-equipment coverage, route-based PM and SLA reporting. Quoting runs from the job record to an accepted proposal, and invoicing runs from the job. Serialized inventory ties parts to the truck and the job, subcontractors and vendors share one compliance queue, and customers see their own quotes, invoices and documents through a magic-link portal.
In the field. Technician mobile web app. Install it to the home screen, and it keeps working with poor or no signal; changes sync when you reconnect.
On the phone. After-hours call answering that takes the caller’s details and drafts the work order for your office to confirm.
Automation. Thermal’s automation framework is in production. The available modules are smart scheduling, PM sweep and PM optimization, dispatch auto-assign, agreement renewal, AR and collections follow-up, quote follow-up, equipment health, KPI watch, call intake drafting, pre-visit briefing, refrigerant compliance and accounting sync. Each has Off, Suggest and Auto modes and a mandatory reason string on every action, behind a per-company master kill switch, with an activity ledger of what ran and why (automation). Nothing is forced on: each module is available, and you decide which ones run and how far.
Integrations. QuickBooks Online two-way sync (customers, items, invoices, payments) (QuickBooks integration). Xero, Sage Intacct and Microsoft Dynamics 365 Business Central are on the roadmap. Approved technician hours export as a generic CSV or an ADP RUN time-sheet import file (canonical facts). Card payments and text messaging are built in: technicians take a card on site or send a Pay-Now link, and the invoice closes out the moment it is paid; appointment reminders and “tech on the way” texts go out from your shop’s number (integrations). Invoices and proposals go to customers by email.
Security. Security details are on Thermal’s security page.
A young, fast-moving product
Thermal is modern, lightweight and agile. The company says it is “early — still a small team, on purpose, for now” (about), and it ships that way: one schema, with Rentals and Job costing labelled as early access modules while they mature. No commercial-customer testimonials are public yet (canonical facts), so judge it on your own data. The trade is agility over tenure: a fast-moving product that changes often.
Who should pick Thermal, and who should look elsewhere
Pick Thermal if you run a commercial or mechanical shop with 5 to 200 technicians, more than one trade, and a book of agreements on equipment you maintain. Switching cost is low: bring your price book, skip the implementation project, and stay month to month.
Look elsewhere if you need live Xero, Sage Intacct or Business Central sync today, or if you are a single-trade residential crew that does not track equipment; Jobber or Housecall Pro are the better fit there.

How we scored Thermal
We reviewed Thermal’s public platform, equipment, agreements, automation, industries, integrations, migration, contract-terms and security pages against the workflows commercial contractors run. Scores reflect documented capabilities and editorial assessment rather than hands-on testing.
Feature depth scores highest because equipment, agreements, PM and dispatch are wired together in one schema. Usability scores well for a lightweight product with no implementation project. Integrations score lowest because, with card payments and text messaging built in, QuickBooks Online two-way sync (customers, items, invoices, payments) is the one live accounting sync today, and Xero, Sage Intacct and Business Central are on the roadmap. The overall score is 8.7.
Verdict
Thermal is the equipment-first choice for multi-trade commercial and mechanical contractors. The unit is the record, agreements are written against it, and PM, dispatch and invoicing follow from it. It is a young, fast-moving product, and its switching cost is low: bring your price book, skip the implementation project, and stay month to month.
