Whether you call it invoice management, a app for jobs, or a invoicing system — most hvac technicians in Carmel string together and other tools. That's $2,520/year in SaaS payments. Across five years at today's prices, that stack costs $12,600.

In July his phone starts before the truck warms up, because the first 95-degree day turns every weak compressor into an emergency. He loads the manifold gauges, checks the refrigerant on the truck, and heads to a no-cool call where a capacitor's blown and the homeowner is sweating and impatient. He recovers refrigerant on a leaking system and has to write down exactly how much, because the EPA log isn't optional. The next stop is a maintenance-agreement tune-up; he runs the combustion analyzer, checks static pressure, and notes the unit's a fourteen-year-old that's living on borrowed time, which is a financing conversation for later. Between calls he's quoting a condenser replacement, checking whether the compressor is still under the manufacturer's ten-year parts warranty, and fielding three more emergency calls he can't all reach today. He pulls a vacuum on a new line set, watches the micron gauge, and charges the system by weight. By evening he's behind on paperwork: warranty serials to record, refrigerant amounts to log, and two estimates to send before customers call competitors. He restocks the truck, checks tomorrow's tune-up route, and knows the heat wave means another fourteen-hour day.
That is the work Nexa is built around: the job, the client, the hours and the invoice live in one place, so the paperwork side of the day doesn't need a second shift.
Every one of those was bought once and earns its keep for years. Nexa is priced the same way: $279 once, and it keeps working whether business is busy or slow.

We build a hvac technician's guide the same way every time, and we'd rather you trust it than take it on faith. Nexa is our product, so the test we hold ourselves to is simple: a tool only "wins" a job here when it genuinely does that job better for a hvac technician — and where something free, open-source, or buy-once does it better, we say so and link you to it. Where Nexa falls short (payroll is the honest example), we name the alternative outright.
Found something out of date? Prices change and we don't catch every move the day it happens. This guide is published and maintained by the Nexa team; if a figure here is wrong, tell us and we'll fix it — getting it right matters more to us than the sale.
