What invoicing app do HVAC technicians use?
HVAC and air con technicians use SMASH to invoice service calls, split system installs, refrigerant top-ups, emergency call-outs, parts and service agreements without typing it all after hours. Save your labour rates, refrigerant pricing, common parts and call-out fees once, then describe the job by voice from the van. SMASH builds the GST-compliant invoice, separates labour, refrigerant and parts, adds compliance notes, and can sync it to Xero or QuickBooks.
The HVAC invoicing problem
Sound familiar? You're not alone.
Refrigerant quantities to price accurately
How many grams of R410A? What was your rate per gram? Guessing means margin leaks on every regas job.
Emergency call-outs after hours
A 10pm breakdown is invoiced the next morning. After-hours rates, attendance fees and approval notes go fuzzy overnight.
Service and install on the same day
Two different job types, two different rate cards, on one invoice that needs to be clear for the customer.
Multi-unit commercial sites
Office buildings with a dozen units need site notes, unit identifiers and per-unit billing — not one vague "AC service" line.
Service agreements and recurring visits
Annual contracts, quarterly maintenance and filter schedules need consistent invoicing with correct rates every time.
Parts from the wholesaler
Capacitors, contactors, filters and expansion valves have trade pricing and markup that gets estimated or forgotten under pressure.

In practice
Just describe the job
SMASH turns your voice into a complete, priced invoice. Here's what that looks like for hvac & air con technicians.
You say
""Air con service and regas at the Parramatta office. Daikin 7.1kW split system. Two hours labour, topped up with 600 grams R410A, replaced filter pad.""
SMASH invoices
AC service + regas — 2 hrs labour + 600g R410A + filter pad = GST-ready invoice with refrigerant line item
You say
""Emergency breakdown at the Bondi restaurant. Cold room compressor, after-hours call-out, three hours, replaced capacitor and contactor.""
SMASH invoices
Emergency repair — after-hours call-out + 3 hrs fault labour + capacitor + contactor + payment link
You say
""New split system supply and install at the Cronulla residential. 6kW Mitsubishi, standard single-phase install, four hours labour.""
SMASH invoices
Split system install — supply + standard install + 4 hrs labour, GST and payment link ready
You say
""Repeat quarterly service for the Melbourne office block. Twelve units, filter clean and check, same rate per unit as last quarter.""
SMASH invoices
Quarterly service — saved client, 12 units, standard rate repeated with today's date and service notes
Built for the trade
Built for how hvac & air con technicians run
Refrigerant pricing by gram or kilogram
Save R410A, R32 and R22 rates. Mention the quantity used and SMASH calculates the exact refrigerant line item.
After-hours and emergency rates
Separate rates for standard, after-hours and emergency call-outs. Say which applies and SMASH uses the right fee.
Labour, refrigerant and parts together
Describe the job once. SMASH separates hours, refrigerant, parts and consumables into clear line items for customers and accountants.
Multi-unit commercial invoicing
Invoice commercial sites with unit identifiers, site notes and per-unit service items so facility managers can approve clearly.
Quote to invoice for new installations
Quote supply and install before work starts, record approval, then convert the approved quote to an invoice when commissioned.
Service agreement invoicing
Quarterly, six-monthly and annual service contracts saved as repeat invoice templates with standard site rates and terms.
Gmail quote requests
Open an HVAC enquiry in Gmail, use the Chrome extension, and turn the email into a quote without switching tabs.
Xero + QuickBooks sync
Starter and higher plans sync invoices to accounting software so the van invoice does not become a second admin job later.
