The scheduling and invoicing app built for HVAC technicians
HVAC swings between planned and urgent: spring and fall tune-up season, then a heat wave fills the week with no-cool calls. MyKlient keeps maintenance plans on schedule while emergency jobs slot into the gaps — and every invoice goes out before you leave.
Scheduling that fits the work
Recurring spring and fall maintenance visits book themselves a season ahead. When an emergency call comes in, you see today's gaps instantly and squeeze it in — and a one-tap 'Running late' text keeps the next customer patient.
Client management that remembers everything
The client card holds what the basement will make you forget: furnace and AC model and serial, filter sizes, last service date, breaker panel location, and photos from previous visits. Repeat calls start with context instead of archaeology. Maintenance-plan customers are flagged as such, so you know who gets priority when the first heat wave hits.
Invoices that go out before you do
Quote the repair, get the nod, then send a branded invoice with parts and labor as line items. Week, month, quarter, and year tabs show exactly how tune-up season and emergency season each performed.
Texts your clients actually want
Time windows are HVAC's reputation-maker: 'On my way' and 'Running late' texts are one tap, and 'Job completed — invoice sent' follows the moment you finish. A quick broadcast in April — 'AC tune-up slots are booking' — reaches your whole client list from your phone and fills shoulder-season weeks.
Set up in an afternoon
HVAC is one of the 18 trades MyKlient pre-loads: pick it at sign-up and maintenance service types and checkmarks arrive ready to shape into your tune-up routine — a checklist the customer can see reflected on the invoice. Import your client base from a spreadsheet and the fall rush is scheduled in an afternoon, not a weekend of data entry.
