What HVAC software actually has to do
Before you compare tools, get clear on the two halves of an HVAC business, because most software only handles one well. The first half is service: a customer's system is down, a dispatcher assigns the closest tech, the tech shows up, diagnoses, fixes, and invoices — one tech, one call, one day. The second half is installs and replacements: a full system changeout is a two-to-three-day job with a small crew, an equipment delivery to coordinate, and a quote-to-job handoff that has to survive the gap between the sales visit and the install date. A tool that treats an install as one giant service appointment will fight you every week.
On top of both sits the recurring layer that keeps an HVAC business alive between emergencies: maintenance agreements. Preventive-maintenance (PM) contracts are the recurring revenue that carries the slow shoulder seasons, and the software you choose either makes them effortless to schedule and track or lets them rot in a spreadsheet until customers churn.
So the real checklist is: can it quote and run installs as multi-day crew work, dispatch and invoice service calls cleanly, and keep PM agreements scheduled and visible — without you buying three separate apps to do it? Everything else is a detail. Start there.
The decision criteria that actually matter for HVAC
Ignore feature-count marketing. For an HVAC operation, five criteria decide whether the software fits the way you actually work. Weight these, and let everything else be a tiebreaker.
- Recurring PM scheduling — Maintenance agreements are recurring revenue, not a nice-to-have. The software must turn a contract into repeating visits (quarterly, biannual, annual) with the right crew and the customer's history attached, and remind you before the renewal lapses. If PM lives in a spreadsheet, you will lose agreements and the revenue that smooths your off-season.
- A real dispatch board — For service, the dispatcher needs to see who's where and assign the closest available tech fast. GPS-aware assignment and same-day reassignment matter more than a beautiful drag-and-drop calendar you'll use twice. Judge the board on a busy Monday, not in a demo with three fake jobs on it.
- Equipment and service history per address — This is the criterion most buyers underrate. When a customer calls, the tech should tap the address and see every system installed there, its install date, and warranty status — so they know in ten seconds whether a part is covered. Software that treats each visit as a blank slate makes your techs guess and your customers wait.
- Mobile tech workflow — Your techs live on a phone in an attic or a mechanical room, often with bad signal. The field app has to be genuinely usable one-handed: pull up the job, see the history, snap tagged photos, capture a signature, and clock in with GPS — ideally offline, syncing when it reconnects. A powerful office dashboard with a weak mobile app is a tool your techs will quietly route around.
- Invoicing and payments that close the loop — The job isn't done until it's paid. Look for invoicing that flows straight from the completed job (or the accepted quote), takes payment on-site or via a link, and syncs to your accounting so you're not re-keying every invoice into QuickBooks. Every manual re-entry step is a place money leaks or stalls.
Install workflow: the criterion service tools quietly fail
Here's the split that trips up most HVAC buyers. The best-known field-service platforms — the ones built around service dispatch — are genuinely excellent at the one-tech-one-call-one-invoice loop. But a system replacement isn't that shape. It's a quote for specific equipment (tonnage, SEER, model numbers, labor by phase), an e-signature that converts to a real job, a two-to-three-day schedule for two-to-four techs, and an equipment-delivery date the whole thing depends on.
When you demo a tool, don't let them show you a service call. Ask them to walk a full changeout: quote with equipment line items, homeowner signs, it becomes a multi-day crew job, the supplier delivery slips a day, you reschedule. If that flow is clumsy — if the install is really just a padded appointment — you've learned the most important thing about the tool, and you learned it before you signed. If your revenue is meaningfully installs, this criterion outranks the prettiest dispatch board on the market.
In Vexor
Vexor was built to handle both shapes without a second app. Install quotes carry equipment line items (tonnage, SEER, model numbers, labor by phase) with e-signature that converts an accepted quote into a job; that job schedules as crew assignments across multiple days with the equipment delivery tracked as a job event, so when a supplier slips you reschedule without losing the rest of the week. Service calls still get same-day, single-tech dispatch with GPS routing and on-site invoicing. It's honest about its lane, though: for heavy-commercial HVAC with building-management-system integration, chiller maintenance, or complex prevailing-wage requirements, a specialized commercial platform is the better fit.
Red flags that cost you money later
A demo is engineered to look good. These are the structural warning signs that don't show up in a demo but show up on your invoice and in your onboarding — watch for them specifically.
- Per-tech (per-seat) pricing — This is the big one for HVAC, because your headcount swings and your busy season needs bodies. Per-user pricing punishes exactly the growth you want: hire your third or fourth tech and your bill jumps a tier. Quote-only enterprise field-service platforms commonly land around $300+/tech/mo, which for a 10-tech shop can mean $20k–$60k/year. Do the math at the crew size you're growing into, not the one you have today.
- Quote-only pricing with no public number — If a vendor won't publish pricing and routes you straight to a sales call, that's a signal the number is high and negotiated per-account. There's nothing wrong with enterprise software that's worth it — but for a residential or light-commercial HVAC contractor, opaque enterprise pricing is often a sign you're being sold a tier above your business.
- Weeks-long (or paid) onboarding — If a tool requires a multi-week implementation, a dedicated onboarding fee, and a data-migration project before your crew can use it, factor that real cost and delay into the decision. Powerful platforms sometimes justify it; but for most residential HVAC shops, software you can't be running inside a day is a red flag, not a feature.
- A service-only tool sold to a business that also does installs — If the platform's whole model is one-tech-one-call, and half your revenue is multi-day installs, you'll spend every install week fighting the tool. Conversely, be wary of a heavy commercial-project platform (built for large GCs) sold to a service-heavy HVAC shop — it's the same mismatch in the other direction.
- Charging extra for the basics — Watch for add-on fees on things that should be included: extra for the mobile app, extra for more photo storage, extra per invoice. Nickel-and-dime pricing turns an attractive headline rate into a bill you can't predict.
Where Vexor fits — honestly
Vexor is field-service and crew-management software for residential and light-commercial trade contractors, and HVAC is squarely in its lane — specifically because it handles installs and service in the same tool without per-tech billing. Two plans, no per-seat fee: Field at $99/mo and Operations at $199/mo, both with unlimited office users and unlimited field crew plus subcontractors, and a 30-day free trial with no card. That pricing model is the deliberate answer to the per-tech red flag above: hire a fourth tech or ten seasonal helpers and your bill doesn't move.
Field ($99) covers the core HVAC workflow: quoting and estimating with line items and e-signature, jobs, a customers/CRM record that holds equipment and service history per address, job photos tagged by category with EXIF and GPS, crew scheduling for multi-day installs, GPS time clock, team messaging, JSA for electrical and refrigerant hazards, daily logs, and unlimited subcontractor invites. Operations ($199) adds invoicing, payment tracking, per-job profit dashboards, advanced reports, a branded client portal, custom permissions, and QuickBooks Online sync — the pieces that close the money loop.
And here's the honest boundary, because a buyer's guide that only sells is worthless. Vexor does not do CAD or automated equipment takeoff, it doesn't generate EPA Section 608 refrigerant-compliance reports (it captures the refrigerant data per call; you export it to a compliance tool), it doesn't natively bill recurring PM contracts on autopilot (you run PM as recurring jobs and invoice per-visit or annually), and it isn't built to replace a heavy-commercial platform with BMS integration and certified prevailing-wage payroll. If those are core to your business, pair Vexor with the specialist tool — or choose the specialist. If your business is residential and light-commercial HVAC that does both service and installs, it's built to be the one tool instead of four.
In Vexor
The tell that Vexor fits an HVAC shop is the install workflow: quote equipment as line items, e-signature converts it to a multi-day crew job, delivery date rides as a job event, and the customer record surfaces every system you've installed at that address with its warranty status on the next service call — all at $99–$199/mo flat, with the crew unlimited. Contractors who were quoted $20k–$40k/year by an enterprise service platform for a similar feature set are the ones this is built for.
Step by step
- 1
Map your revenue split first
Before you look at any tool, write down what share of your revenue is service calls versus installs/replacements versus PM agreements. That split, not a feature list, decides which capabilities you weight — a service-heavy shop and an install-heavy shop should buy differently.
- 2
Score the five criteria that matter
Rate each candidate on recurring PM scheduling, a real dispatch board, equipment/service history per address, mobile tech workflow, and invoicing/payments. Weight them by your revenue split. Let everything else be a tiebreaker.
- 3
Make them demo a full install, not a service call
Ask the vendor to walk a complete system changeout: equipment quote, e-signature, multi-day crew schedule, a supplier delivery that slips, and a reschedule. If the install is clumsy, you've learned the most important thing before signing.
- 4
Do the pricing math at your growth headcount
If pricing is per-tech, calculate the annual cost at the crew size you're growing into, not today's. Add any onboarding or migration fees and per-invoice or storage add-ons. Compare that total honestly against a flat per-workspace plan.
- 5
Test the mobile app in the field, offline
Put the app in a tech's hands in an attic or mechanical room with bad signal. Can they pull the job and history, snap tagged photos, capture a signature, and clock in — one-handed, and does it sync when signal returns? The office dashboard is never the bottleneck; the field app is.
- 6
Run the free trial on real jobs
Use any no-card trial to run two or three actual jobs — one service call, one install, one PM visit — end to end, quote to invoice. A tool that survives your real workflow for a week beats one that dazzled in a 30-minute demo.
