HVAC contractors are running more software than any other residential trade, partly because the business model is complex: you have service agreements, seasonal maintenance visits, emergency calls, equipment installs, fleet management, and a financing component all running simultaneously. Most HVAC shops that are growing beyond 3-4 techs are using at least 5-6 software tools, whether they realize it or not. This guide lays out the complete software stack for HVAC contractors in 2026, with pricing and specific recommendations by company size.
Why HVAC Contractors Need a Defined Software Stack
The alternative to a defined software stack is not simplicity. It is a collection of disconnected apps, shared spreadsheets, sticky notes, and group texts that creates exactly the kind of friction that prevents a business from scaling. Techs call the office to check availability instead of seeing a schedule in an app. Invoices get created in one place and tracked in another. Service agreements exist in a spreadsheet that two people are editing from different devices.
A coherent software stack does not mean the most software possible. It means the right tools in each category, connected where they need to be, and not duplicated where they do not need to be. The goal is one tool per job, with the minimum overlap.
The 6 Categories Every HVAC Operation Needs
1. CRM and Field Service Management (FSM)
This is the core of the stack. Your CRM and FSM is the system where customers exist, jobs are created, techs are dispatched, and work orders are completed. Everything else either feeds into this or pulls from it.
ServiceTitan is the enterprise-tier option for HVAC. It was built specifically for the trades and has the deepest HVAC-specific feature set: service agreements with automated renewal reminders, flat-rate price book, dispatch board, custom forms for install completion, and strong reporting. Pricing is not public but starts around $398 per month for smaller shops (as of 2026) and scales significantly for larger operations. Best fit: shops with 5 or more techs who need the full commercial-grade feature set and have the budget to match.
Jobber and Housecall Pro are the right-sized options for small to mid-sized HVAC shops (1-10 techs). Both include scheduling, dispatch, customer communication, invoicing, and mobile apps for techs. Jobber starts around $49 per month. Housecall Pro starts around $69 per month. The main difference in an HVAC context: Housecall Pro has a slightly deeper service agreement module out of the box, while Jobber has stronger quoting and proposal tools.
2. Customer Financing
HVAC is one of the highest-volume use cases for contractor financing because of large ticket sizes and frequent emergency situations. The two platforms most HVAC shops should know:
Hearth is the right choice for shops doing $46,000 or more in financed volume per year. Flat annual fee, 18-plus lenders, no per-job dealer fees. See Hearth’s program details here.
Wisetack is the right starting point for lower-volume shops or shops that want a no-commitment entry into financing. Per-job fee starting at 3.9%, no annual fee.
For shops with manufacturer dealer relationships, EnerBank (Regions Bank) or manufacturer-specific programs handle the 0% promotional financing that comes with seasonal equipment promotions.
3. Invoicing and Payments
Most HVAC shops handle invoicing through their CRM (Jobber, Housecall Pro, or ServiceTitan all include invoicing). The main decision is where to integrate accounting. QuickBooks Online is the standard for HVAC accounting integration and connects natively with all three major FSM platforms. Pricing starts around $30 per month (as of 2026) for the Simple Start plan. For shops doing custom fabrication or tracking equipment inventory, QuickBooks Plus (around $90 per month) with class tracking is worth the upgrade.
4. Marketing and Reviews
Google Business Profile (free) is the highest-leverage marketing tool for any local HVAC business. Regular photo updates, responding to reviews, and posting seasonal promotions all contribute to local pack rankings.
NiceJob or Birdeye automate the review request process. NiceJob starts around $75 per month (as of 2026) and sends automated review requests via text and email after job completion. Birdeye is a more full-featured reputation management platform starting around $299 per month. For most HVAC shops, NiceJob is sufficient and significantly cheaper.
5. Dispatching and GPS Fleet Tracking
For HVAC shops with 3 or more trucks on the road, GPS fleet tracking has a clear ROI through reduced fuel cost, better routing, and accountability for drive time. Samsara and Motive (formerly KeepTruckin) are the two most commonly used platforms in residential trades. Both start around $25-$35 per vehicle per month as of 2026. The main difference is that Samsara has stronger hardware integration and a more mature HVAC fleet feature set, while Motive is generally slightly cheaper and has a cleaner mobile interface.
If you are using ServiceTitan, its built-in dispatch board handles most of the scheduling and dispatch workflow without a separate fleet tool. The GPS fleet tool fills the gap for real-time location tracking and vehicle diagnostics.
6. Estimating
For HVAC equipment installs, most shops use either ServiceTitan’s built-in price book (which supports flat-rate pricing), Jobber’s quoting module, or a standalone tool like Improveit 360 or a custom flat-rate price book built in a spreadsheet or PDF template. The main thing to get right is having a standard flat-rate book so techs are not creating custom prices in the field. For shops that do new construction or commercial work with plan-based takeoff, a separate tool like PlanSwift is worth adding.
Complete Tool Table
| Tool | Category | Starting Monthly Cost | Best For |
|---|---|---|---|
| ServiceTitan | CRM / FSM | ~$398+/mo | 5+ tech shops needing enterprise features |
| Jobber | CRM / FSM | ~$49/mo | 1-5 tech shops, strong quoting |
| Housecall Pro | CRM / FSM | ~$69/mo | 1-5 tech shops, service agreements |
| Hearth | Financing | ~$150/mo (annual) | High-volume financing shops |
| Wisetack | Financing | No fee (3.9% per job) | Lower-volume or entry-level financing |
| QuickBooks Online | Accounting | ~$30-90/mo | All shops needing accounting integration |
| NiceJob | Reviews / Marketing | ~$75/mo | Automated review requests |
| Samsara | Fleet / GPS | ~$27-33/vehicle/mo | 3+ truck shops needing GPS tracking |
Estimated Total Stack Cost by Company Size
1-tech solo operation: Jobber ($49) + Wisetack (no monthly fee) + QuickBooks Simple Start ($30) + Google Business Profile (free) = roughly $80 per month. Add NiceJob ($75) when you are doing enough jobs to justify the review automation.
3-5 tech shop: Housecall Pro or Jobber ($69-$149 depending on plan) + Hearth ($150/mo on annual plan) + QuickBooks Plus ($90) + NiceJob ($75) + Samsara for 3 vehicles ($81-$99) = roughly $465-$563 per month. That stack runs a full-service HVAC operation efficiently.
10+ tech operation: ServiceTitan ($398+, likely $600-$1,200 at this scale) + Hearth ($150) + QuickBooks Plus ($90) + Birdeye ($299) + Samsara for 10 vehicles ($270-$330) = roughly $1,300-$2,100 per month. ServiceTitan replaces many point tools at this level, so the total cost is proportionally lower per tech than it looks.
