Field Ascend is heat pump service software for U.S. HVAC teams that install, commission, maintain and repair air-source heat pumps, ductless mini-splits, hybrid systems and related heating and cooling equipment.
Use one platform for scheduled preventive maintenance, emergency repairs, mobile technician updates, asset history, follow-up quotes and billing handoff.
From $13/user/month. All core features included for U.S. service teams.

Heat pump service software helps HVAC contractors manage installations, preventive maintenance, service agreements, technician dispatch, equipment history, photos, checklists, quotes, invoices and customer updates in one system.
Heat pump fleets live or die on maintenance discipline. Missed seasonal services shorten equipment life, void manufacturer warranties and turn small faults into emergency call-outs, so contractors need service intervals, equipment history and field evidence in one connected record rather than scattered across spreadsheets and paper job tickets.
Field Ascend ties every air-source heat pump, mini-split and air handler to its own service history, automates the preventive maintenance schedule, and gives technicians an offline mobile app for readings, photos and checklists. Findings flow straight into quotes and invoicing, so revenue from follow-up repairs is never lost between the field and the office.
Recurring service contracts need planned visits that are easy to schedule, track and prove.
Create recurring maintenance schedules for heat pumps, mini-splits, air handlers and connected HVAC assets.
Keep upcoming and overdue visits visible so the office can protect maintenance revenue and customer uptime.
Technicians need the service history and checklist in the field, even when signal is unreliable.
Give technicians access to customer details, site notes, equipment records and previous visit history.
Standardize field capture so every visit produces useful evidence for the customer and office.
Small findings during a service visit should not disappear into notes that nobody prices.
Technicians can record recommended repairs, attach photos and keep findings tied to the asset.
Accepted quotes can become scheduled work orders without retyping the same information.
