About this example
This example is the invoice an air conditioning contractor in Honolulu, Hawaii, sends a dental practice after a repair and a scheduled maintenance visit: one of three split systems had stopped cooling, and the engineer found a failed capacitor and a refrigerant leak at a service valve, then serviced all three units under the maintenance agreement.
Facilities and practice managers approve an HVAC invoice when they can see what was wrong and what was done, so this one identifies the unit by model and serial number and ties the invoice to the job sheet. The repair is billed as a call-out, engineer and apprentice hours, and each part, with the refrigerant charged by the pound and weighed in to the nameplate charge. The maintenance visit, filters and condensate drain service follow under the agreement. Hawaii's general excise tax applies to the labour and parts alike. A table of readings shows the unit before and after the repair, the recommendations are priced, and the invoice ends with payment details and terms on warranty, refrigerant handling and late payment.
Who it is for
Air conditioning and HVAC contractors, refrigeration engineers and building services firms that invoice repairs and maintenance visits to their customers.
