What an AI receptionist does for a Centennial phone line

A missed call can waste a search that cost money to win. Lithium Marketing puts an AI receptionist on a Centennial service business’s phone line and builds custom automation for the work around the call. “Garage door repair centennial” alone draws about 50 searches a month. The phone can ring while the crew is on a job.

“Electrician centennial” draws about 170 searches a month, and “pest control centennial” draws about 50 searches a month. Every one of those searches can end in a call, and the receptionist answers with your services, hours and service area before booking the job or sending the call to the right person.

The Centennial market

Who calls a Centennial service business

Most occupied homes in Centennial belong to the people who live in them: 80.6% are owner-occupied. Centennial holds 43,291 housing units in all, and a caller may still be a tenant, a landlord or a property manager, so the receptionist can ask who controls the property and send that call where you want it.

The median home in Centennial was built in 1983, so the knowledge base should answer older-home questions in your words: which repairs you take on, what you need to see first and when a job needs a different trade.

Trades in Arapahoe County

Repair calls and project calls need different rules

Arapahoe County has 251 plumbing, heating and air-conditioning contractors. When a burst pipe or a dead furnace needs same-day help, the receptionist follows your rules: ring the on-call tech, hold the first opening or send the address and issue by text.

Arapahoe County has 129 painting contractors, and a caller planning a paint job describes a room, a cabinet or an exterior. The receptionist captures the scope, address and timing before putting the estimate on your calendar.

Set up for you

Getting the receptionist ready for Centennial calls

Nothing goes live until you have signed off on how each kind of call is handled.

1

Decide what a person must hear

Start with the calls that need a human, such as an emergency or an existing customer, and decide where those calls should ring. The rest can be booked or answered by text.

2

Teach it the jobs you take

The receptionist learns your services, the cities you cover, your hours and the answers you want it to give, then says them in the voice you pick.

3

Choose where bookings and transfers land

We test the calendar or CRM you already use before connecting it, then set the number a transfer rings.

4

Call the line and fix what sounds wrong

You call the finished line yourself, and we rewrite any answer that sends a caller the wrong way before it takes a live call.

What the AI receptionist does on every call

The same eight parts go into every AI receptionist setup, wherever the business is.

Proof

A plumbing after-hours system and a garage door website

One example is a plumbing company that was losing after-hours emergency calls to voicemail until Lithium built a custom AI phone system. The other is Smart Doors LLC, a garage door company that took a website first and later added the AI receptionist for its phones.

Around Centennial

A phone line that covers the whole service map

A caller does not care which city the job sits in. The receptionist can cover Highlands Ranch, Aurora, Denver, Lakewood, Westminster and Arvada from the same number, and each city link below opens its own AI page. The Colorado directory lists the rest of the state.

FAQ

Centennial phone questions, answered

Still curious?

Call (503) 766-5964 or email [email protected].

What happens when a caller asks for a person?

The receptionist transfers the caller to the number you choose. You decide which calls need a person, such as an emergency or an existing customer, and everything else gets answered, qualified and booked or sent a follow-up text.

How does $179 a month compare with a receptionist hire?

Compare the two bills: $179 a month for the AI receptionist, with no contract and no setup fee, and $3,500 or more for a person at the front desk. The AI also works nights and weekends, when one hire is off.

How long does setup take?

Allow a few days. Lithium needs your rules, the services you sell and access to the calendar, then builds the voice and answers. You get to call the line and hear it before any customer does.

Who gets the 2 a.m. emergency call?

The call goes to your on-call tech if your rules send emergencies there. The receptionist asks how urgent the problem is, then transfers the call, holds the next opening or texts the details to your team.

Can it handle follow-up texts and CRM updates?

Texts after a call and calendar bookings come with the receptionist. Work beyond the phone, such as syncing a CRM, requesting reviews or processing documents, is a separate automation project that Lithium scopes on a free discovery call.
