How your Phone Calls Are Processed by Centratel
Incoming Calls
Our Telephone Service Representative (TSR) answers a call promptly, stating, “Answering for (your HVAC company’s name.) How may I assist you?” (Of course, this “phraseology” can be adjusted to your preference.)
Screen for Urgency
Our TSR quickly determines if the call is urgent or not, based on the pre-determined criteria that you’ve specified.
Message Information
The TSR takes all the pertinent information from your caller: name, phone number, and the reason for the call, then informs your caller they should expect a return phone call within a specified amount of time.
Notify On-Call
Our agent either instantly dispatches the message by texting the on-call technician (called, CLEAN-SCREEN℠ service, and preferred by most of our HVAC clients) or by placing a direct call to the tech. Your choice!
Instantly enhance the efficiency of your HVAC operation.
You know it’s true: Four out of five first-time callers to your company will hang up if they can’t reach a human being, with the vast majority never calling back. Missed calls mean forever lost opportunities. By employing Centratel, no calls will be lost. You’ll have 100% call-capture.
24/7 Live Answering Service
Offer uninterrupted client support—as well as new-customer call capture—with our super-efficient 24/7 live answering service that includes emergency response, after-hours front-office answering, and daytime overflow call-traffic support. Our highly paid career Telephone Service Representatives will process your calls around the clock so you can coddle your customers with an always-reliable connection to your company.
Call Capture
When you are unavailable to take calls, we’ll cover for you, ensuring no calls go unanswered. Whether it’s regular customer inquiries or urgent messages, our flawless call-capture protocols guarantee that your people are always in the loop, never missing a beat. Dramatically elevate your customers’ experience today with our tailored call-capturing approach.
Free Automated Message Delivery
Messages can be delivered via email, text message, alpha-pager, or fax, at no extra cost. And these message-delivery mediums can be combined to meet your exact requirements. These options ensure that you and your people receive critical information immediately, streamlining your customer service and offering a seamless, perfect experience for your HVAC staff.
Online Message Portal
Centratel’s secure, hyper-efficient online message-access feature allows you to retrieve and manage messages from anywhere at any time, eliminating the need for phone-call inquiries to our agents. Say goodbye to missed messages and hello to a more efficient, responsive, and productive way of managing your HVAC business!
US Based…and Zero Artificial Intelligence
For four decades (our 40th anniversary is December 1, 2025), Centratel has been proudly owned and operated exclusively within the United States by a single owner, Sam Carpenter. We never route calls offshore. Never! And we don’t use AI for call handling. We promise one hundred percent human engagement.
Monthly Billing Cycle
Centratel’s billing process encompasses an entire month, resulting in twelve statements per year. In contrast, and as a too-clever method of surcharging their customers, many of our larger competitors use a 28-day billing cycle, effectively creating an additional thirteenth billing statement in a given year. Centratel’s traditional, clearly defined monthly billing is transparent, consistent, and simple to understand.
Pay-per-Call
And, unlike many of our competitors, we charge for the work we accomplish, not for the time we spend with your callers.* At Centratel, we offer a fixed fee for each call, while we don’t charge for electronic message delivery. This ensures clear and predictable costs, leading to understandable and dependable billing.

Why Choose Centratel
BY SAM CARPENTER
May 1, 2025
1.CENTRATEL’S UNIQUE 30-DAY FREE TRIAL
Why is this important? Because it will provide you a truly accurate estimate of cost (we bill monthly), it will demonstrate our quality, and it gives both sides of this brand new relationship—you and Centratel—plenty of time to refine and perfect operational details.
Here’s a testimonial from a new medical client that had just finished their 30-day trial: “Of course, I love the cost as it is close to the amount I was allowed by the president of the company. I told him that if we did not continue with Centratel, I would resign as the Director of Customer Service, and I meant it. It’s a great fit. We have had NOT ONE complaint from a patient or in-house which, as you know, we received daily with our former answering service. I love you, Centratel, and the price. I’m ready to sign whatever documents you require. Thanks for the great service, and the free month! To a great partnership! -KB, Phoenix“
2.STATISTICALLY, THE BEST IN THE U.S.?
Answering service quality is 100% dependent on human action and reaction, and in the course of a single day a multitude of human decisions are made by the people who process the calls: Telephone Service Representatives, or TSRs. (Some answering services refer to them as “agents.” Others, “operators.”)
Like any other answering service, at Centratel we’re dealing with real live human beings and so human errors can occur. But within this labor intensive service industry that is historically known for marginal quality, Centratel’s error rate is light years ahead of established standards. Our most recent Customer Reported Error Rate (January through December, 2024) was 1 customer-reported error for every 6,161 message transactions processed. That statistic is unmatched.
There’s no artificial intelligence manipulation, we do not offshore calls, and we were founded and have always operated within the United States. (Note that since early 2020, the COVID six-foot social distancing mandate drove thousands of small-to-medium sized answering services out of business. Large, often foreign-owned multi-nationals, disguised by the name of the local answering services they acquired, now thoroughly dominate the industry. Hence, an even further decline in general service quality. See this analysis.)
3.CUSTOMER SERVICE EXTRAORDINAIRE
Your concerns will be instantly acted upon. It’s a work ethic that stands in stark contrast to the general quality decline in human-to-human business-customer communications nowadays. You’ve seen it yourself, all around. At Centratel you will know by name the customer service people you’re working with, appreciating their special listening abilities as well as their take-action-now comportment. i.e. see the testimonial in point #1 above. ‘Nuff said!
4.GETTING STARTED: IT’S SIMPLE AND FAST
Getting your new Centratel answering service 30-day free trial started is accomplished within 24-48 hours. From the start, your “onboarding” customer service representative will be with you every step of the way, listening carefully to your concerns, answering questions and offering suggestions.
5.NEW TO USING AN ANSWERING SERVICE?
A majority of our current answering service accounts switched to us from another service because of quality and/or cost problems. However, if you have not used a service before, you are not familiar with the options, benefits, and pitfalls. Our 30-day free trial provides you—and us—plenty of time to precisely refine your desired message-taking and delivery protocols; to get things exactly the way you want them to be without any financial risk, undue pressure, or obligation.
6.PRICING
Starting at $150 per month, our rates lie in the mid-range of the industry. Note that we charge by the “transaction unit” rather than the duration of time spent handling calls. Large “mega-services” operating in the U.S. prefer time billing because it ensures the company is compensated for lower-paid/high-turnover — and thus slower — agents. No matter the quality or how long they keep your callers on hold, they still make a profit. And yes, it can also get expensive, especially if caller on-hold time is also billed.
In any answering service, it takes a long time for a new agent to become fast, efficient, and stable. At Centratel, we pamper and reward experienced agents (via higher pay and great benefits) and therefore have extremely low staff turnover. Needless to say, experienced agents make fewer errors than trainees who learn on-the-job. And, transaction-unit billing is easy to understand. There is no room for fraudulence as in time-billing. We can easily document and explain any monthly billing we send you.
7.ACCURATELY COMPARING ANSWERING SERVICE PRICING IS COMPLICATED
It’s apples and oranges. There isn’t an industry standard for billing, and each answering service has its own formula. Also, as noted above, some services charge by agent “time” while a few still charge by “transaction units. Some others combine the two. At Centratel, we charge for the work we do, not by the time we spend. The raw truth is that the only reliable way to determine monthly cost for a new service is to use that service for a solid month. Most answering services offer a 7-day free trial or no trial at all. With Centratel you get 30-days.
8.BEWARE: MONTHLY OR 28-DAY BILLING?
Important! At Centratel, we use a “monthly” billing cycle in which invoices are compiled from the first day of a month to the last day of that month. When soliciting quotes from other services, be sure to ask if the base-rate charges are billed monthly or on a “28-day billing cycle.” There is no good reason for a 28-day billing cycle! It’s bait-and-switch: customers billed on a 28-day cycle actually receive thirteen billings per year and therefore the overall cost is higher.
9.NO CONTRACT AND SIMPLE TERMS OF SERVICE
We don’t ask for a term contract for service because you should be able to evaluate us real-time, without restraint. Our terms of service are simple and straight-forward.
10.VALUABLE FREE GIFT FOR CONTACTING US
If you take the time to discuss answering service with us, on the same day we will ship you a hardcover copy of Sam Carpenter’s bestselling book, Work The System: The Simple Mechanics of Making More and Working Less, now just released in its 5th edition. We’ll send you a copy just for contacting us. (Sam is Centatel’s (very active) CEO. December 1st 2024 marked his fortieth year of ownership.)
