Free HVAC Scheduling Software in 2026: Dispatch, Booking, and Maintenance Agreements

Krib Team · 2026-06-10

HVAC scheduling is harder than most trades: summer AC surges, winter heating emergencies, and maintenance agreements that repeat every season. This guide covers what HVAC appointment scheduling software actually needs to handle, why per-tech pricing punishes seasonal shops, which "free" tools are really trials, and how to run dispatch, customer self-booking, and recurring tune-ups at $0/month.

What is the best free HVAC scheduling software?

Krib is one of the best free HVAC scheduling software options in 2026. It includes a drag-and-drop team calendar, multi-technician dispatch, a customer booking widget with conflict detection, recurring service scheduling for maintenance agreements, and a technician PIN portal — all at $0/month with no per-user fees and no trial expiration. FieldVibe offers free scheduling for a single user, and Google Calendar is free but has no dispatch or job workflow.

Is there HVAC appointment scheduling software that is actually free?

Yes, but read carefully — most "free" results are 14-day trials (Jobber, Housecall Pro) or single-user freemium caps (FieldVibe). Genuinely free HVAC appointment scheduling software charges no monthly fee and no per-user fee with no expiration. Krib fits that definition: it makes money from optional payment processing (standard Stripe fees plus a 0.1% platform fee), not subscriptions, so the scheduling features stay free whether or not you ever process a payment.

What is HVAC booking software and do I need it?

HVAC booking software lets customers schedule their own appointments from your website or Google Business Profile instead of calling. The customer picks a service type and an open time slot, and the booking lands on your calendar. It matters most during seasonal surges, when missed phone calls are missed revenue. Look for conflict detection (so customers can only book genuinely open slots) and lead capture. Krib includes a free embeddable booking widget that auto-creates a lead from every booking.

How do I schedule recurring HVAC maintenance agreements for free?

Use a tool with recurring service scheduling rather than repeating calendar events. In Krib, you set up each maintenance agreement customer once with their visit cadence (for example, a spring AC tune-up and a fall heating check), and the visits regenerate automatically each cycle — connected to the customer record, service history, and invoicing. That prevents the common failure mode where agreement visits get postponed during the busy season and never rescheduled.

How much does HVAC scheduling software usually cost?

Paid options range widely. Jobber runs $22–$387/month on annual prepaid billing ($49–$699/month month-to-month) with $29/month per user beyond your tier cap (verified May 2026). Housecall Pro runs $59–$299/month annual ($79–$329/month monthly) with $35/month per extra user on MAX (verified May 2026). ServiceTitan reportedly costs $245–$500+ per technician per month with implementation fees of $5,000–$50,000 and is aimed at larger operations. Krib provides scheduling, dispatch, and customer booking free, with revenue coming from optional payment processing instead.

Can my technicians see their own schedules with free HVAC software?

Yes. Krib includes a technician portal at no per-user cost — each tech logs in on their phone with a PIN and sees their own daily schedule with job details, addresses, and customer info, plus clock-in/clock-out for timesheets. You assign jobs from the dispatch calendar and each technician sees only their own day.

Is there free HVAC business software that goes beyond scheduling?

Yes. Krib pairs its free scheduling with the rest of the business workflow: multi-option quotes, invoicing, Stripe payments, a CRM lead inbox, customer chat, QuickBooks sync, permanent property and service records, and a homeowner portal — all free with no per-user fees.

Does free HVAC scheduling software work in Spanish?

Krib is fully bilingual — the scheduling calendar, dispatch, booking widget, technician portal, and customer-facing notifications all work in both English and Spanish, and you can switch languages anytime in settings. Most established platforms like Jobber and Housecall Pro offer their dashboards primarily in English.
