The same receptionist who answers our own line — call and she picks up, 24/7. No signup, no sales pitch.

The calls you're missing are the expensive ones

The 6 PM no-cool call

A family's AC dies at dinner time. If your line rings out, they don't leave a voicemail — they call the next company. Della answers on the second ring, books the service call, and texts you the details.

The mid-job ring

You're elbow-deep in an air handler and the phone buzzes. Let it ring — Della takes the message, marks it urgent if it is, and your on-call tech gets a text (and a phone call that reads the message out loud, on the Office plan).

The Spanish-speaking caller

Tampa Bay speaks two languages. So does Della, on every plan — greet callers in Spanish, run whole calls in Spanish, or switch mid-sentence. The Office plan adds 18 more languages.

The maintenance-plan spring rush

Tune-up season floods the line with bookings. Della books them straight into your calendar — real appointments, reminders included, no double-booking.

Your number, honestly

Say you miss 5 calls a week and win half of them back, at an average repair ticket around $450:

≈ $59,000 a year, answered back

That's the yearly revenue sitting in unanswered rings — and one install call you save pays for Della for a year by itself. Run your own numbers in the cost calculator.

Built for how your phone actually rings

Emergency dispatch

Urgent no-cool with a baby in the house? Your whole on-call list gets texted instantly; the first tech gets a call reading the message aloud.

Booked, not just answered

Service calls land on your calendar with confirmations and 24-hour reminders — synced to Google, Apple, or Outlook.

Every call texted to you

The moment a call ends you get a text with the name, address, and the job — you decide who runs it without digging through voicemail.

Remembers your regulars

Maintenance-plan customers get greeted like the regulars they are — she knows who they are and what unit you service.

Della Desk is run by HG Installations LLC, a Tampa Bay trades company — we bid jobs, miss calls, and answer to GCs like you do. She answers our phones too: we built her because we needed her.

What it costs

Plans from $35/month (answering, messages, bookings) to the full front office. Most HVAC companies land on Front Desk at $89 or Office at $149 — every plan includes 100 minutes, and extra minutes are always a flat 30¢, dialed in advance. Every price is public on the pricing page. No setup fees, 7-day free trial, and no surprise bills, ever: if you use up your minutes, nothing extra is billed — you pre-choose whether the line pauses or steps up, and a one-time $50 top-up adds 100 minutes.

Questions owners ask

Can she tell an emergency from a tune-up request?

Yes — you set the house rules in plain English ("no cooling with elderly or infants at home = urgent"). Urgent messages trigger the dispatch cascade; routine ones book or wait politely in your inbox.

What happens during a heat wave when everyone calls at once?

She answers every call simultaneously — there is no busy signal, no hold queue, no fifth ring. That's the whole point.

Does she know refrigerant from a capacitor?

She knows your business: your services, your service area, your pricing rules, your FAQs — you teach her in plain English in about five minutes, and she never freelances technical advice you didn't approve.
