HVAC service software that remembers every unit
Equipment make, model, serial, and refrigerant type at every site — so techs roll prepared, diagnostics get documented, and invoices go out with the job still warm.
No credit card required. Signup starts you on the HVAC Service setup — you can change your business type later.
Sound familiar?
The problems that eat evenings in a hvac service business.
Every call starts with twenty questions
What's the unit? How old? What refrigerant? If the answers aren't on the site record, the tech spends the first visit rediscovering them.
Seasonal crunch breaks the board
The first heat wave stacks service calls faster than a whiteboard can absorb, and no-cool customers don't wait quietly.
Diagnostics evaporate
The fault code, what was found, what was recommended — if it never leaves the tech's head, the callback three weeks later starts from scratch.
Invoices trail the work
Paper tickets ride around in the van for a week before anyone can bill them.
How FieldLasso runs your day
Build the site's equipment record
Equipment type, make, model, serial number, installation date, and refrigerant type live on the service location — every future call starts informed.
Dispatch the crunch
Drag service calls between techs on the dispatch board as no-cool calls stack up. Scheduling stays timezone-correct.
Document the diagnosis
Diagnostic codes and findings recorded on the service call are visible to the tech in the field app. Field photos remain offline-safe in basements and attics.
Invoice and collect on site
The completed service call generates the invoice with the equipment serviced noted on it. Techs collect card payment in the field through Stripe.
Built for hvac service
The HVAC Service pack calls service calls what you call them and ships with the fields your paperwork already asks for.
Equipment type
Furnace, AC, heat pump, boiler, mini-split, or packaged unit — on the site record before the truck rolls.
Refrigerant type
Kept with the equipment so the right recovery gear is on the truck.
Diagnostic code
The fault code recorded on the service call, so the callback conversation starts from evidence.
Equipment model
With make, serial number, and installation date, the unit's identity lives at the site.
Equipment serviced
Shown on the invoice, so customers see exactly which unit the charge covers.
HVAC Service FAQ
Can I keep equipment history per address?
Yes. Make, model, serial number, installation date, equipment type, and refrigerant type are fields on the service location, visible to the tech in the field app.
How do urgent no-cool calls get scheduled?
Drop them on the dispatch board and drag work between techs to make room. Customers who opt in to texts get an on-the-way message.
Can techs collect payment on completion?
Yes — invoices generate from completed service calls and techs take card payment in the field through Stripe-hosted entry.
Do maintenance visits recur automatically?
Put the client on a recurring plan and visits generate on schedule — useful for seasonal tune-up customers.
