HVAC SOFTWARE
HVAC software that answers the no-heat call.
Fasite is HVAC software for a small heating and cooling business: customers, estimates, jobs, your techs' calendar and invoices in one place, plus a website built by our team and an AI receptionist that answers a new local number 24/7 when you are on a roof or under a house. One plan, Fasite Pro, is $199 a month with no charge per user, and it starts with 30 days free.

The no-heat call goes to voicemail.
A family with no heat on a freezing night does not wait for a callback. They call the next company on the list.
The AI receptionistThe AI receptionist answers its own number, takes the address and what has failed, offers two open times for a free visit or takes a message, and saves the call as a lead with a summary. - 7:30 AM
The first cold snap fills the week overnight.
Calls come in faster than the techs can cover them, and the whiteboard is out of date by breakfast.
FasiteEvery job sits on one dispatch board. Drag it onto a tech, and each person on it gets an email with the change. Each tech's day is on a private phone link. - 3:15 PM
The furnace quote goes out and goes quiet.
A replacement is a big yes. It leaves as a photo of a page, with no repair option beside it and no easy way to say yes.
FasitePick the lines from your price list and the prices fill in. Offer repair or replace, mark the thermostat optional, and email it. The customer picks on their phone and signs.
One furnace replacement, start to finish.
One job moving through Fasite, on Fasite Pro. Every picture is drawn from the real product, on sample data.
Repair or replace. The customer picks and signs.
Pick lines from your price list and the prices fill in. Offer a repair or a new furnace, mark the thermostat optional, then email it. They choose on their phone, sign with their name, and you get an email the moment they say yes.
The yes becomes a job.
It lands with every line they chose. Drag it onto a tech on the dispatch board, and each person on it gets an email with the change.
Their day is on their phone.
Each tech gets a private link with their jobs, addresses, gate codes and notes, and never your prices. No app, no password. They tap On my way, and the customer gets an email.
Finished work waits in Ready to bill.
One tap drafts the invoice, and you send it. Set reminders once, and Fasite emails anyone who is late.
Repeat work books itself. You see what it made.
A monthly filter check repeats on its own. Set it weekly, every two weeks or monthly, tech and all. Reports show who owes you and what each job earned.
The no-heat call at 2 a.m., answered.

- Answers 24/7: nights, weekends, and while you're in an attic.
- Offers two open times and books the free visit on the first call.
- Saves every call as a lead, with a summary in your email.

The 2 a.m. call does not go to voicemail

Short answers.
Get the call answered, get a tech there, and get paid. Fasite answers calls 24/7 on a new local number, works as HVAC scheduling software with your techs' jobs on one board and their phones, and turns finished work into invoices that track what is paid and what is owed.
With Fasite it is $199 a month, or $165.83 a month billed yearly, with no charge per user. That includes the website, the AI receptionist with 500 minutes a month, and the tools for estimates, jobs, techs and invoices.
For a small crew, yes. As HVAC field service software it keeps customers, jobs, a dispatch board for your techs and invoices in one login. It is not a large field service suite: it does not plan routes, track trucks with GPS or run a field app, and your techs use a phone link.
Yes. Finished jobs wait in Ready to bill, and one press makes a draft invoice you check and send. Each invoice shows paid, owed, part paid or overdue, so it works as HVAC billing software without retyping the job.
Fasite keeps a record for each customer and one lead inbox for every call and web form, next to estimates, jobs and invoices. As HVAC contractor software for a small crew, that puts the whole job in one login, with a website built by our team and a new local number for the AI receptionist.
Start the 30-day free trial. No card is needed to start. Ask for your website and a person on our team builds it the same day, with a preview link before it goes live. After the trial it is $199 a month, with no contract.
Yes. Pick the lines from your price list, mark extras like a smart thermostat as optional, and email it. The customer chooses on their phone and signs with their name, and you get an email the moment they say yes.
The receptionist answers on its own number. If anyone could be in danger, it tells them to hang up and call 911. Otherwise it takes their number and what has failed, and the details land in your inbox and in an email to you. It never quotes a price.
Yes. Set a visit to repeat weekly, every two weeks or monthly, tech and all. Each visit lands on the dispatch board and on that tech's phone link, and a finished one waits in Ready to bill.
No. Fasite runs the business side: calls, estimates, jobs, techs and invoices. You size the system and write the estimate from your own numbers.
