The second trip is the most expensive event in a service business, and most second trips are a part that was not on the truck. Inventory management in a small HVAC business is therefore mostly about the truck: what each vehicle carries, what was used on which ticket, and what needs restocking before tomorrow. Installs add the material list per job. This page is for the owner or service manager of a US HVAC contracting business asking what HVAC inventory management software should do, what the truck's HVAC inventory list should hold, and how the equipment list and material list templates keep installs from stalling at the supply house.
The truck's HVAC inventory list is the product
Each truck carries a defined stock: capacitors by rating, contactors, motors by common frame, igniters, flame sensors, thermostats, filters by common size, refrigerant, fittings, wire, fuses. The list is set from what the trucks actually used last season, reviewed twice a year, and restocked to a par level. Software or spreadsheet, the discipline is the same: a list per truck with a par quantity and a count.
Parts used against the ticket
The list only stays true if every part used is recorded against the ticket that used it, at the moment it is used. HVAC inventory management software does this by letting the technician pick the part from the truck's list when pricing the repair, which decrements the count and prices the part from the book at once. If the technician has to record the part twice, once for the price and once for the stock, the stock record will be wrong within a week.
Restocking without a phone call
At the end of each day the software should show, per truck, what fell below par and produce the restock list for the supply house run or the warehouse. The best products let the technician scan the restock in. Without software, the same job is a spreadsheet the office updates from tickets, which works for two trucks and fails at five.
The HVAC equipment list template and the HVAC material list template
Installs need two lists per job. The equipment list names the units by model and serial with their accessories: pad, disconnect, thermostat, lineset kit. The material list names the consumables and fittings: refrigerant, brazing rod, nitrogen, hangers, sealant, wire by gauge, drain fittings, flue components. Build both from the quote so the supply house order is placed the day the job is sold and the crew loads from the list rather than from memory.
When to buy software for it
When the truck count outgrows one person's spreadsheet, or when the parts on tickets stop matching the parts leaving the shelf. Inventory is usually a module of a broader product. Jobber lists Core at $49 per month for one user and $29 per month for each additional user; Housecall Pro lists Basic at $79 per month for one user. CoilDesk Pro is $29 per month for the whole crew; the material list arithmetic for a quote is on the quote builder here for free.
Questions people ask about hvac inventory management software
How often should the truck's HVAC inventory list be counted?
A quick daily check against the restock list and a full count monthly. The daily check is what stops the second trip.
Should technicians be able to see other trucks' stock?
Yes. The part that saves the second trip is often on the next truck over, and the dispatcher should be able to see it.
Do we need separate HVAC inventory management software?
Rarely. Inventory should live with the ticket and the price book so a part is recorded once. A separate inventory product means recording it twice.
