HVAC contractors live in a constellation of software: a CRM for dispatch and invoicing, a website for marketing, a quoting tool, maybe QuickBooks, maybe email and SMS. When those systems don't talk to each other, your team wastes hours re-typing data and leads get lost between apps.
This guide focuses on the integrations that matter for HVAC in 2026 — what to look for, where each major CRM shines, and a reference architecture that wires everything together.
The four major HVAC CRMs in 2026
ServiceTitan
The enterprise option. Built for shops doing $2M+ in revenue with dispatch, call centers, and complex reporting needs. Deep integration library (Zapier, Make, dozens of native partners). Starting cost is high — usually $500–$1,000+ per user per month — but the integration surface is the best in the industry.
- Best for: Shops with 10+ techs, multiple trucks, and office staff.
- Strongest integrations: Google LSA, direct-to-QuickBooks, nCino, third-party quoting tools.
- Weakest: Overkill for 1–5 tech shops. Onboarding is 30+ days.
Housecall Pro
The mid-market option. Simpler than ServiceTitan, cleaner mobile app, price lands around $50–$150 per user per month. Integrations are growing fast — Zapier, QuickBooks, Google, Mailchimp, Stripe, and an open API.
- Best for: Shops with 2–15 techs.
- Strongest integrations: Stripe, QuickBooks, Mailchimp, Google Local Services.
- Weakest: Not as deep on call-tracking and marketing attribution.
Jobber
Similar tier to Housecall Pro — clean, mobile-friendly, and priced from $40–$120 per user per month. Integrations are solid but lean more toward field-service-general, not HVAC-specific.
- Best for: Shops doing mixed service (HVAC + plumbing + electrical).
- Strongest integrations: QuickBooks, Stripe, Zapier, Google Calendar.
- Weakest: Lighter on HVAC-specific features (equipment tracking, IAQ options).
Workiz
The scrappy option. Affordable ($50–$100/user/month), solid built-in call-tracking, and a handful of native integrations. Good choice for shops just moving off spreadsheets.
- Best for: 1–3 tech shops starting their first CRM.
- Strongest integrations: Call-tracking, SMS, QuickBooks.
- Weakest: Smaller partner ecosystem than the top three.
The integrations that actually matter
You don't need every integration in the marketplace. You need these seven:
- Your website → CRM. When a lead submits on your site, it should create a job card in your CRM with name, address, phone, and quoted options — no re-typing.
- CRM → QuickBooks. Invoice sync, tax handling, and payment reconciliation. Saves ~10 hours/week on the admin side.
- Phone → CRM. Call tracking with attribution (CallRail, ServiceTitan Pro, Workiz native). Shows which marketing channel is actually producing jobs.
- Email/SMS → customers. Appointment confirmations, on-my-way texts, invoice links, and review requests.
- Google Business Profile → CRM. Messages and booking requests from GBP land in your CRM, not a random inbox.
- Online review requests. Automated after every completed job — NiceJob, Podium, or native.
- Filter/maintenance subscriptions → CRM. Recurring revenue belongs in your CRM alongside service jobs, not a separate spreadsheet.
A reference architecture for HVAC contractors
Here's the setup we see perform best for shops doing $500K–$5M in annual revenue:
- Website: Modern marketing site with embedded instant quoting tool.
- Quoting + lead capture: DinoQuote (generates estimates, captures homeowner info, pushes to CRM).
- CRM: Housecall Pro or ServiceTitan, depending on size.
- Filter + maintenance subscriptions: DinoQuote filter store and maintenance plans, synced into CRM.
- Payments: Stripe or native CRM processing.
- Accounting: QuickBooks Online.
- Reviews: Podium or NiceJob firing automatically after each job.
This stack takes the friction out of the lead-to-invoice flow without locking you into any single platform.
How DinoQuote fits in
DinoQuote is intentionally CRM-agnostic. It sits on your website as a quoting, filter store, and maintenance plan layer — and syncs leads and subscriptions directly into ServiceTitan, Housecall Pro, Jobber, or Workiz. You keep your existing dispatch and invoicing system; DinoQuote handles the customer-facing “shop from my website” experience.
Every lead created on your website lands as a full customer record in your CRM — ready to be dispatched, called, or closed. No double entry. No lost leads.
How to choose
If you're evaluating right now, use this shortcut:
- Doing <$500K/year or 1–3 techs: Workiz or Jobber.
- Doing $500K–$2M: Housecall Pro.
- Doing $2M+: ServiceTitan.
- Any size: Add DinoQuote as the website/quoting layer — it works with all of the above.
The right CRM saves you hours per week. The right integrations save you revenue per customer. Don't overthink the platform — just make sure everything connects.
