Which calls reach the on-call tech?

A no-cooling call needs the address, symptoms and urgency before it reaches dispatch. Your rules decide whether it needs an on-call handoff or the next available visit. Live transfers are on Pro. A reported gas smell goes to emergency guidance rather than repair instructions.

  • No heat or no cooling: capture symptoms and route by your urgency rules.
  • Repair or tune-up: offer the next available visit in your service area.
  • Replacement estimate: book the assessment; quote only your approved rates.

What happens when the calendar is full?

The caller gets the next available option or a callback request. A full calendar never becomes a made-up appointment. If nobody accepts an urgent handoff, the caller gets the fallback you chose and your team gets the call details.

Dallas calls need a real service-area check

A heat-wave call in Dallas and a maintenance request across the metroplex need different scheduling decisions. Give the front desk the ZIP codes you cover, your travel limits and the on-call schedule. It checks those before offering a slot.

Answer first. Text when a call cannot connect.

The first job is to answer the phone and finish the booking conversation. Missed-call text back is the backup. Replies stay with the customer's request so the office does not have to reconstruct it later.

What are your missed calls worth?

Those inputs put about $3,248 in potential bookings at stake each month.

Missed calls per week × 4.33 weeks × average value × the share that would book. Booking value is not profit or a promise of recovered sales.

That's more than Core costs. Core is $697 a month. See the plans

What each plan includes

Three plans, month to month. Every plan answers every call, texts back missed calls and books on your calendar. See every plan

Frequently asked questions

Before you choose an answering service

Does the HVAC answering service cover after hours?

Yes. It answers after hours using your booking and handoff rules. An answered call does not mean a technician is available; the caller gets confirmed availability or the next step you set.

What does Front Desk cost?

FlowChainLabs Front Desk has three plans: Core $697, Plus $997 and Pro $1,497 a month. Each added location is $397 a month. No contract, no per-minute bills, unlimited changes. See every plan at https://flowchainlabs.com/front-desk.

Can I keep my business number?

Yes. Keep the number customers already call and forward the calls you want Front Desk to answer.

Does it book appointments?

It books available times on your connected calendar, using your service area and booking rules. We check the connection to your scheduling software before promising a direct booking there.

What happens when a caller needs a person?

It takes the caller's name, callback number and reason for calling. Pro adds live transfer to your team using your handoff rules. A person decides what needs a visit or a specialist.

Does the price go up in a busy month?

There are no per-minute bills. Pick the plan for the work you need handled, rather than a minute allowance.

Who changes the answers when my hours change?

We do. Send the new hours, service area or booking instructions and we update the front desk for you.
