BuildOps is the best software for a commercial mechanical or HVAC contractor, because it is built for the service trades and handles both service work and projects in one system. A custom system from Black Badger ranks third, behind ServiceTitan, and it moves up when your maintenance agreements, dispatch rules or project billing do not match what a product expects.
The ranking, entry by entry
1 BuildOps
Best for commercial mechanical firms running service and projects
A mechanical contractor runs two businesses. One sells service agreements and dispatches technicians, and the other builds projects with crews and change orders. BuildOps is first because it names mechanical and HVAC contractors as its market and suits a firm that runs both sides. It also connects to Viewpoint Vista, Viewpoint Spectrum, Sage Intacct, NetSuite and QuickBooks, so the accounting system a contractor of this size already has can stay.
Watch for. Pricing depends on field and office user counts, trades and back office tools, and none of it is published. Fleet+, Payments+ and CRM+ cost extra.
- How it charges
- Quoted by field and office users, trades and back office tools
- Main limit
- Built for commercial service trades, with add-ons for fleet, payments and CRM
2 ServiceTitan
Best for service-led HVAC companies with many technicians
ServiceTitan ranks second for HVAC. If most of your revenue is service calls and maintenance visits, it puts dispatch, invoicing and payroll in one system built for a large technician team. Memberships are part of the product, though customizable memberships are not listed on the two lower plans. It ranks behind BuildOps for this question because a mechanical contractor with a construction division needs the project side as well.
Watch for. It is priced per technician and every plan says Request Pricing. Add-ons such as Dispatch Pro are listed without prices and sold separately.
- How it charges
- Per technician, by plan, quoted on request
- Main limit
- Payroll, advanced reporting and commissions sit in higher plans
3 Custom build by Black Badger
Best for mechanical contractors with their own agreement and billing rules
Black Badger publishes this guide and builds custom software, and for mechanical contractors that route ranks third. Good products exist for this trade, so we do not put ourselves first. A build fits when your maintenance agreements, dispatch rules or project billing are particular enough that the office keeps a second set of records to make the product work. We build those rules in, connect to accounting, and you own the code with no per-seat fee.
Watch for. If BuildOps or ServiceTitan covers your work with ordinary setup, choose one of them. A build begins with discovery and a written scope.
- How it charges
- One-time build scoped in writing, then running costs such as hosting
- Main limit
- Needs a scoping call first, and suits companies of 50 or more employees
What a custom build involves, and how to ask about one
4 eSUB
Best for mechanical subcontractors that are mostly project work
eSUB is fourth. For the plan-and-spec side of mechanical work it gives foremen and project managers field and project tracking, with change orders, T&M tracking and progress billing in its Advanced tier. A mechanical contractor that does little service will find it a closer fit than a dispatch product. It ranks below the top three here because it is a project tool, and service dispatch is not what eSUB describes.
Watch for. Drawings and integrations are optional add-ons. QuickBooks Online is the one accounting integration the homepage names, so ask about yours.
- How it charges
- Quoted by user count and modules, not by annual revenue
- Main limit
- Built for subcontractors, with drawings and integrations as optional add-ons
5 FOUNDATION
Best for mechanical contractors that want payroll and dispatch together
FOUNDATION ranks fifth. Its core is Job Costing, Payroll and Accounts Receivable for contractors, and Service Dispatch is available as an add-on module. For a mechanical contractor with complicated payroll, having dispatch belong to the same product that pays the technicians is attractive. It ranks here because dispatch is an add-on to an accounting product.
Watch for. Service Dispatch, Mobile Time Tracking and Equipment Management are each add-on modules. Pricing is modular with no published amounts.
- How it charges
- Quoted, modular pricing with paid add-on modules
- Main limit
- Modular pricing, with Service Dispatch and Equipment Management as add-ons
6 Microsoft Dynamics 365 Field Service
Best for mechanical contractors standardized on Microsoft tools
Microsoft Dynamics 365 Field Service is sixth. It is a general field service product with a published per-user price, billed yearly. The fit is a company on Microsoft 365 and Dynamics that wants service connected to its other Microsoft tools. It ranks low for mechanical contractors because it is sold for field service and not for construction projects, so the project side needs another system.
Watch for. Resource Scheduling Optimization is a paid add-on billed per resource. The lower-priced Contractor plan does not include planned maintenance agreements.
- How it charges
- Per user, billed yearly, with per-resource add-ons
- Main limit
- Schedule optimization is an add-on charged per resource
7 Procore
Best for large mechanical contractors on big construction projects
Procore ranks seventh for this trade. A large mechanical contractor working on major projects may be asked to work in the general contractor's platform anyway. Owning its own account gives its project teams one system with no user charge. It ranks last here because the service business, which carries a mechanical contractor between projects, is outside what the Procore pages we read describe.
Watch for. The fee is based on annual construction volume, and Field Productivity is priced separately based on FTE.
- How it charges
- Annual fee by product, based on construction volume
- Main limit
- Priced on your annual construction volume, so cost rises as your work grows
Questions buyers ask
Should a mechanical contractor run service and construction in the same system?
Service and construction should run in the same system if the same customers, technicians and equipment appear on both sides. Splitting them means two customer lists and two versions of job history. BuildOps is aimed at exactly that combined shop. If your service and construction divisions operate apart, two tools can work.
What does field service software cost per technician?
Most trade vendors quote field service software per customer and publish no price. ServiceTitan prices per technician and shows Request Pricing on every plan. Microsoft publishes a per-user price, billed yearly, for Dynamics 365 Field Service, with schedule optimization as a paid add-on per resource. Use the vendor's published price list as a reference point when a quote arrives.
When does a mechanical contractor need a custom system?
A mechanical contractor needs a custom system when the office is running a second set of records to cover what the product cannot do. Typical cases are maintenance agreements with unusual billing, dispatch rules tied to technician licenses, or project billing an owner dictates. Black Badger scopes that in writing before anything is built.
