Free HVAC software.
More room to run your shop.

Free HVAC software should complete a real service call, not merely store a contact or generate one invoice. Start with the working path: book the customer, schedule and assign the visit, find the property and equipment context, document the work, and prepare the invoice.

ClimaCall connects that path for an HVAC shop. Review the detailed scheduling, dispatch, work-order, and invoicing workflows instead of choosing from a feature list alone.

Free Forever includes up to 3 users and 20 work orders per month. It does not expire, and no credit card or contract is required. When you process payments for 5 work orders through ClimaCall Payments, the work-order allowance becomes up to 50 for that monthly cycle.

Those limits are part of the offer, not fine print. If your normal workload is above them, review current pricing before moving live work into the system. Payment-processing charges are separate from the software subscription.

A free trial ends after a stated number of days or requires payment to continue. ClimaCall Free Forever does not expire while the shop stays within the plan limits. The practical upgrade trigger is work volume or team size, not a countdown clock.

Core costs $49.99 per technician per month and includes up to 2 free back-office seats. The back-office allowance belongs to Core and does not add users to Free Forever.

1. Create a sample customer, property and equipment record.
2. Schedule and assign a representative service call.
3. Open the work order from the technician view and record the work performed.
4. Prepare the invoice and inspect the payment workflow.
5. Confirm that the office can find the same job details after the visit.

Route optimization and automatic estimate follow-up are available. GPS technician tracking and financing prompts are in development. Job-profit reporting is basic. Use the work-order guide, invoice guide, and current feature list while evaluating.

Free Forever is a practical starting point for an owner-operator, a new HVAC business, or a small team that can work within the user and monthly work-order limits. It gives the team a way to test a real workflow instead of choosing software from a feature list alone.

If you are adding technicians, need more capacity or want to compare team costs, see HVAC software for small businesses and the Core team-size examples. Core is $49.99 per technician/month and includes a maximum of 2 free back-office seats; that allowance does not add users to the Free plan.

Before switching systems, list the integrations, reports, permissions and data you actually need. Keep an export of existing records and validate a small sample before moving the rest. Free migration assistance covers organized customer, property and basic service-history data from supported spreadsheets or exports; cleanup and manual entry require a separate review.

For a one-person workflow, read the owner-operator guide. ClimaCall can serve HVAC shops across supported service areas, but local licensing, tax, payment, consumer, safety, code, and recordkeeping requirements remain the contractor’s responsibility.
