Sound Familiar?

It's July, 97 degrees, and your phone won't stop ringing. You just finished an AC repair and the homeowner wants a receipt. You've got two more calls stacked and a maintenance agreement customer who was supposed to be scheduled last week. You're drenched in sweat, typing an invoice on your phone with greasy fingers, and you can't remember if you charged this customer the diagnostic fee or waived it.

Why HVAC Technicians Are Fed Up

"Minimum $300+/month with annual contract. They don't care that you're solo — same price as a 10-truck company."
— Common HVAC tech complaint about ServiceTitan
"No scheduling, no dispatch, no job costing without add-ons. You end up paying for QBO plus another app anyway."

Invoice from the truck: the 90-second close

Finish the job, tap the saved service, add any extras, send. The customer pays from the link before you've left the driveway. The longer an invoice sits, the lower the odds it's paid in full — speed is the collection strategy.

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 $355/month for ServiceTitan + QuickBooks — that's $14,293 over 3 years. Nexa saves you $14,014 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 ServiceTitan?

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.

How does Nexa compare to what other hvac technicians spend?

The median HVAC tech earns $50,590/year. Software subscriptions at $4,260/year represent 8.4% of that income — every single year. Nexa at $279 once is 0.55% of annual income, paid one time. The difference compounds every year you operate.

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 tech 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 Manifold gauge set you bought once is finally matched by software you buy once. The "seasonal income swings — buried in summer, slow in spring/fall" 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 0.8 months. 30-day money-back guarantee. And because there's nothing to renew, a HVAC tech who switches keeps paying $0/month while competitors keep paying $355/month — that gap compounds every year you own it.
