Best Software for Mechanical & HVAC Contractors (2026)

The two-sided problem mechanical contractors have

A mechanical contractor doing new commercial construction needs job costing built around production units — linear feet of ductwork, linear feet of pipe by size, tons of equipment set, hours per fixture or connection — the same discipline covered in our <a href="/blog/mechanical-estimating-labor-units">mechanical labor units guide</a>. That side of the business lives and dies on cost-coded daily reports and a real-time budget-vs-actual.

The service side of the same business — PM contracts, emergency repair calls, T&M billing — needs something almost entirely different: dispatch and scheduling, technician routing, time-and-material invoicing generated on-site, and often recurring maintenance contract tracking. A contractor running both sides typically ends up either running two separate software systems (with no unified view of company profitability) or picking one tool and living with a weak second half.

How the main options compare

<a href="/vs/servicetitan">ServiceTitan</a> and similar field-service platforms (also see our <a href="/vs/housecall-pro">Housecall Pro</a> and <a href="/vs/jobber">Jobber</a> comparisons) are strong at what they are built for: dispatch, technician scheduling, and service-call billing, particularly for residential and light-commercial HVAC. Where they fall short for a mechanical contractor with a real project division is cost-coded job costing on new construction — labor-unit tracking, AIA progress billing, RFIs and change orders — which is simply not the workflow those platforms were designed around.

<a href="/vs/simpro">Simpro</a> and <a href="/vs/buildops">BuildOps</a> both attempt to bridge project and service work for mechanical/electrical trades, and are worth evaluating directly against Field PM if that dual-sided need is central to the buying decision — the honest differentiators tend to be depth of cost-coded job costing on the project side versus depth of dispatch/routing on the service side, so the right answer depends on which side of the business is larger.

GC-centric platforms like <a href="/vs/procore">Procore</a> handle multi-trade project coordination well but, as with electrical subs, leave a self-perform mechanical contractor's own crew productivity and service dispatch largely unaddressed — fine as a project-level document system, incomplete as the whole company's operating system.

What to actually evaluate

• •Production tracking by system: can it log linear feet of duct or pipe, tons of equipment, and fixture/connection counts by cost code, and calculate a productivity factor against the estimate?
• •Service dispatch in the same system: if service is part of the business, does scheduling, routing, and T&M billing live in the same app as project job costing, or is it a second tool with no shared data?
• •AIA billing for commercial project work: does progress billing generate from the same quantities and cost codes as the job cost report, or does someone rebuild the schedule of values separately each month?
• •PM contract and maintenance agreement tracking: for the service side, are recurring contracts, visit scheduling, and renewal dates tracked natively?
• •ERP/accounting sync: does labor and job cost data flow to QuickBooks, Sage Intacct, or whatever accounting system runs payroll and AR, without manual re-entry?

Where Field PM fits

Field PM covers both sides in one platform: cost-coded <a href="/features/daily-reports">daily reports</a> and a real-time <a href="/features/pm-dashboard">PM dashboard</a> for the project/install side, and <a href="/features/service-dispatch">service/dispatch (FSM)</a> — scheduling, technician routing, and time-and-material ticketing — for the service side, sharing the same job/customer records and rolling into the same company-wide financial picture rather than two disconnected systems.

That breadth is the honest trade-off to weigh against a specialist tool: a mechanical contractor that is purely new-construction install, with no service division at all, may get more depth from a project-only competitor; one that is purely service, with no project work, may prefer a pure-play dispatch platform. Field PM's case is strongest for the (common) contractor running both, plus needing QA/QC, safety, tool tracking, and ERP sync that a narrower tool does not offer.

Pricing and total cost

Service-dispatch platforms typically price per technician per month, plus add-ons for advanced features like PM contract tracking or marketing tools; project-costing platforms typically price per project-side user. Running two systems means paying two separate subscriptions with no discount for the overlap in company and customer data.

Field PM runs $99-$799/month flat by tier, covering both project and service functionality, with unlimited free foreman/field/technician users — so a contractor with 15 install crew members and 8 service techs is not paying per-seat pricing that scales with every hire on either side of the business.
