For plumbers, HVAC & electricians

The AI receptionist that books the job while you're on one.

Sera answers every call, text and web chat 24/7 — on a roof, under a sink or at 2am. She books estimates and service calls, sorts emergencies from routine work by your rules, and texts back anyone you couldn't pick up.

Example call · 11:06 pm
  1. Caller

    Our furnace just quit and it's 30 degrees out. Can someone come tonight?

  2. Sera

    I'm sorry — no heat in this cold is an emergency. What's the address, and is anyone in the home elderly or very young?

  3. Caller

    88 Birch Lane. Two kids under five.

  4. Sera

    Thank you. I'm sending this to our on-call tech right now — they'll call you back shortly to confirm a time.

Emergency sent to the on-call tech with address and details

Try it right now

Call (650) 795-7838 and ask to book an AC tune-up.

That's Sera, live. Same agent your customers would reach — no form, no sign-up.

Sound familiar?

If you don't pick up, they call the next guy.

You can't answer from a crawlspace

You and your techs are on jobs all day. Every call you let ring is a customer scrolling to the next listing.

Emergencies don't wait for business hours

Burst pipes, no heat, a dead panel — the highest-value calls come at night and on weekends, straight to voicemail.

Messages don't book jobs

An answering service hands you a list of names to call back tomorrow. Half of them already hired someone.

What Sera handles

The office work of a trade business, covered.

Sera works from your own information — services, service area, hours, price ranges and on-call rules — and handles the phone work your office manager would hand to anyone.

  • Service calls & estimates

    Gets the job type, address and access details, offers open windows and books the visit or estimate.

  • Emergency triage & dispatch

    Spots emergencies by your rules — flooding, no heat, sparks — and sends them to your on-call tech right away.

  • Pricing & service-area questions

    Answers "do you service my town?" and gives your trip charge or price ranges for common jobs.

  • Reschedules & ETAs

    Moves appointments and answers "when is the tech coming?" from your schedule.

  • Maintenance plan bookings

    Books seasonal tune-ups and explains your maintenance plans to customers who ask.

  • Missed-call text-back

    Texts anyone whose call you couldn't take, so the job comes to you instead of the next listing.

  • Transfer to you or the office

    Hands live calls to the owner, dispatcher or office with a summary, or books a callback.

Every channel

One dispatcher. One record. Every channel.

Phone, text, website chat or email, it's the same Sera with the same memory — and you see one conversation per customer, not four.

Phone

Forward your business line, or just overflow and after-hours. Sera answers on the first ring.

Text

Booking confirmations, tech ETAs and replies to customers who text you.

Website chat

A chat on your site that books an estimate at 9pm instead of a contact form.

Email

Answers routine questions in your inbox and routes the rest.

Fits your workflow

Jobs and notes where your team already looks.

Bookings land in your schedule or calendar; call notes go to your inbox, phone or CRM.

How it works

Live the same day.

  1. Step 1: Forward your line

    Point your business number, overflow or after-hours line at Sera. Add the chat to your website with one snippet.

  2. Step 2: Sera learns your business

    Services, service area, hours, price ranges and what counts as an emergency. Paste your website and fill in the gaps.

  3. Step 3: Live same day

    Most shops are answering calls in under 30 minutes. Adjust what she books and escalates any time.

Guardrails & trust

She books jobs. She doesn't make promises you can't keep.

Only the prices you set

Sera quotes trip charges and ranges you've given her — never a firm price for a job a tech hasn't seen.

Emergencies go to a human

You define what's an emergency and who's on call. Sera sends it to them immediately and tells the customer what happens next.

Every conversation on record

Each call and chat is logged with a full transcript, so you can see exactly what was said and promised.

Questions, answered

What contractors ask first.

How does an AI receptionist for plumbers work?

Sera answers every inbound call in a natural voice. She works out the job — clogged drain, water heater, leak — checks urgency against your rules, and books the visit or sends emergencies to your on-call tech. Routine questions like service area and trip charge she answers herself.

Can AI handle HVAC call answering?

Yes. Sera handles no-heat and no-cool calls, maintenance and tune-up bookings, and replacement estimate requests, using your service list, hours and emergency rules.

Does this work as an AI dispatcher for electricians?

Sera takes the job type, address and access details, books the visit, and texts a confirmation. Anything you mark as an emergency — no power, sparks, burning smell — goes straight to whoever is on call.

What is missed-call text-back for HVAC and home services?

When you can't take a call, Sera texts the caller back with a short message asking what they need and offering to book. The customer gets a reply instead of a voicemail beep. Missed-call text-back is included on the Growth plan and above.

How is this different from a regular answering service?

An answering service takes a message and you still have to call back, qualify the job and schedule it. Sera books the job in the same conversation and sends emergencies to your on-call tech. Tell us which field service software you use and we'll confirm whether she books straight into it.

How much does this cost compared to hiring a CSR or answering service?

Sera starts at $49/mo, covers nights and weekends, and books jobs rather than taking messages. Booking, missed-call text-back and live transfers are on the Growth plan and above. Try her first: call (650) 795-7838.
