Quick picks
In a hurry? Here's the short version by situation.
How the work actually runs
An HVAC day runs from the phone to the truck.
HVAC is dispatch, diagnosis, and big-ticket closes, smoothed out by maintenance agreements. Here is the daily loop, and where each pick pulls its weight.
The phone rings
The call becomes a booked job with the customer record attached.
All 4 start here
Dispatch picks the tech
The board shows who is where, and the nearest qualified tech gets the job.
Housecall Pro and ServiceTitan GPS
Tech diagnoses and quotes
Flat-rate options on the tablet, good, better, best.
ServiceTitan price book leads
Financing closes the big job
The customer applies from the estimate for the replacement they could not pay cash for.
Housecall Pro and ServiceTitan
Job done, paid on site
Invoice, card, and deposit before the truck leaves the driveway.
All 4 handle this
Maintenance agreement attaches
The one-off repair becomes a recurring service relationship.
FieldEdge agreements lead here
Owner reads the numbers
Revenue per truck, close rate, and agreement renewals.
ServiceTitan enterprise reporting
Season repeats
Agreements smooth the shoulder seasons. That is the model.
The point of all of it
For a shop running roughly 3 to 20 techs, Housecall Pro covers the whole loop in one platform: dispatch, financing on the estimate, payment on site, and more developed marketing than the cheaper rivals. Service Fusion is the flat-fee counter: one company-wide price with unlimited users, if your crews can live without an offline mode.
The other two are commitments with payoffs. FieldEdge earns its contract for established shops anchored to QuickBooks Desktop and maintenance agreements. ServiceTitan is the enterprise system of record, with the deepest price book and reporting in the trade, a quote-only contract, and an implementation that commonly runs 3 to 4 months.
Right pick for your size
The best tool changes with the crew.
A solo operator and a 10-person crew do not want the same software. Pick your size.
Housecall Pro
Real monthly cost, 2 to 5 techs: Essentials as the functional minimum for a small crew
- Scheduling, dispatch, invoicing, payment, and marketing in one platform.
- Wisetack financing and same-day deposits help close replacement jobs.
- More developed marketing automation than the cheaper rivals.
The headline Basic plan is a false floor: it excludes QuickBooks, GPS, and marketing, so Essentials is the real entry.
Full Housecall Pro reviewFlat-fee alternative
Service Fusion — 7.9
One company-wide price with unlimited users. No offline mode is the catch.
QuickBooks Desktop shops
FieldEdge — 7.6
A best-in-class two-way Desktop sync, behind a contract and a multi-week onboarding.
Housecall Pro
Real monthly cost, 6 to 15 techs: MAX tier territory, plus the add-ons you actually use
- Dispatch and the iOS field app hold up across a real board of techs.
- Vehicle GPS and the Profit Rhino price book bolt on as you grow.
- MAX includes a 60-day structured onboarding with a specialist.
Seats overflow at about $35 each above 8, vehicle GPS runs about $20 per truck, and Android app stability trails iOS.
Full Housecall Pro reviewStop paying per seat
Service Fusion — 7.9
Flat per-company pricing pays off fastest at exactly this size.
If you are outgrowing it
ServiceTitan — 8.3
The enterprise step, once you can absorb a quote-only contract and months of implementation.
ServiceTitan
Real monthly cost, 15 plus techs: quote-only, with an annual contract and a real implementation project
- Flat-rate price book, CSR coaching, and multi-location reporting few rivals match.
- Full offline field app, so techs work without signal and sync later.
- Built-in payments and multiple financing partners for big-ticket replacements.
Implementation commonly runs 3 to 4 months, and first-year totals for a 10-tech shop are reported well into five figures.
Full ServiceTitan reviewDesktop-anchored shops
FieldEdge — 7.6
Service agreements and a best-in-class QuickBooks Desktop sync for established operations.
Flat fee at scale
Service Fusion — 7.9
Unlimited users on one bill, if your crews can live without an offline mode.

Housecall Pro
Our #1 Pick· from $79/moThe sweet spot for most HVAC shops: strong dispatch, service agreements, flat-rate pricing, and a great mobile app, without the complexity or cost of an enterprise platform.
Excellent dispatch and mobile app
Solid agreements and pricing book
Some features sit in higher tiers
Less depth than ServiceTitan
- 28.3
ServiceTitan
Best for large ops· Quote-basedThe platform large operations grow into, with deep reporting, financing, and call-center tools. It is powerful and priced for it, so it rarely fits a one or two-truck shop.
Enterprise depth and reporting
Strong financing and memberships
Expensive
Heavy to implement
- 37.9
Service Fusion
Best value· from $245/moFlat per-company pricing with no per-user fee makes it a smart pick for a growing shop adding techs. The flat-rate pricing book is an add-on to plan for.
No per-user pricing
Good value as you add techs
Flat-rate book costs extra
Interface feels dated
- 47.6
FieldEdge
Best for agreements· Quote-basedA solid, service-agreement-focused option for established HVAC and plumbing shops. Dispatch and agreement tracking are strong, but the mobile experience and reporting feel a step behind Housecall Pro and ServiceTitan, and pricing is quote-only.
Strong on service agreements
Good dispatch for office staff
Quote-only pricing
Dated mobile app

All guidesWhat the sticker price hides
The headline is rarely the bill.
Every tool here advertises a low number. Here is what actually lands on the invoice once you run a real hvac business on it.
Housecall Pro
$79/moReal for a 5-truck team with GPS: ~$249/mo
- Basic excludes QuickBooks, GPS, and marketing, so Essentials is the functional minimum
- Vehicle GPS tracking is a paid add-on, about $20 per vehicle a month, on Essentials or higher
- The Profit Rhino flat-rate price book is a separate add-on, around $149 a month
ServiceTitan
Quote-basedReported first year, 10-tech shop: well into five figures
- Pricing is custom and quote-only; the vendor publishes no numbers
- An annual contract is required, with some users reporting multi-year terms
- A mandatory, non-trivial implementation fee applies on top of the subscription
Service Fusion
$245/moReal for a 10-person shop: the same flat bill as a 3-person one
- Plans are flat, but the tiers gate features, so growth can push you up a tier
- No offline mode, so spotty-signal crews lose access in the field
- SMS and payment processing are billed on top of the plan
FieldEdge
Quote-basedReported: low hundreds per user/mo, plus a setup fee
- Pricing is quote-only; the vendor publishes no numbers
- A contract is required and there is no free trial to test first
- Onboarding is a multi-week project, commonly reported around five weeks
Why we show this
No tool here is hiding the ball on purpose, but the sticker is a starting line, not a total. We price the real bill so you compare like for like. Numbers are researched from vendor pricing and docs, not hands-on.
