Sound Familiar?

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.

FAQ

Is Nexa actually built for hvac technicians?

Yes. The invoicing module is designed for hvac technicians who need to professional invoicing with payment tracking, reminders, and automated follow-ups. Plus you get scheduling, CRM, time tracking, and full accounting — tools most hvac technicians end up needing anyway. $279 total for everything.

$279 seems expensive upfront. Is it worth it?

$279 spread over 3 years is $7.75/month. You're currently paying $0/month for — that's $0 over 3 years. Nexa saves you $-279 over that period. The math isn't close.

What if I don't like it?

30-day money-back guarantee. Full refund, no questions. If Nexa doesn't save you $500 in year one, you get every penny back.

Can I switch from my current tools?

Yes. Export your data as CSV, import into Nexa. Most hvac technicians are fully switched in 1-2 days. Run both in parallel until you're confident — zero risk.

Why One App Beats Three Subscriptions

Most hvac technicians cobble together 3-5 separate apps — one for scheduling, one for invoicing, one for bookkeeping, maybe another for client management. Each one charges monthly. None of them talk to each other. So you end up copying client info between apps, manually reconciling invoices with your books, and losing track of details that fall through the cracks.

For the way a HVAC Technician actually works, Nexa keeps one record instead of five logins. You finish the job and the invoice generates from that same record — no retyping into a second app between calls. The hours feed your P&L automatically, a client who books online lands in your CRM with their history, and the Refrigerant gauge manifold set and a digital refrigerant scale you bought once is finally matched by software you buy once. The "surviving the summer first-ac-failure crush and the winter no-heat surge while the shoulder seasons go quiet" problem goes away. No Zapier, no CSV exports. $279 once — or $99 today and two more — and the whole integrated system is yours, break-even in ∞ months. 30-day money-back guarantee. And because there's nothing to renew, a HVAC Technician who switches keeps paying $0/month while competitors keep paying every month — that gap compounds every year you own it.
