BUILT FOR RESIDENTIAL HVAC CONTRACTORS
We own the follow-up. You run the jobs.
Book more work before you buy more leads. Plenum follows up on the calls that didn't book, the estimates that didn't close, and the customers already in your system, and shows you exactly which ones turned into booked jobs.
You would never sell a homeowner a part when the system is the problem. We work the same way. Four systems, installed alongside the software you already run, operated every week by one person.

THE REVENUE RECOVERY SYSTEM
FOUR SYSTEMS. ONE PRICE. INSTALLED ALONGSIDE YOUR CRM.
Every one of these goes after work already in your business.
Missed-Call & After-Hours Rescue
A call that rings out at eight on a Saturday gets a text back from your number, usually within a minute. It captures the problem, sorts service from replacement, and books it or gets your on-call tech the details. Plus a number you have never had: how many calls you actually missed last week.
Unsold-Estimate Recovery
An unsigned replacement quote is the most valuable piece of paper in your shop. Twelve to eighteen months of them are sitting in a folder. Those homeowners already let you in the house and already heard your price. They did not say no — nobody followed up. We work that list on a schedule, and every job that comes back is traced to the estimate that predates us.
Database Reactivation
Your past customers get sorted by equipment age. Anything twelve years or older gets a replacement conversation before the season turns. Lapsed maintenance agreements get a renewal reach-out. Everyone else gets a tune-up or a plan offer. It runs on a seasonal cadence, in your name.
Review Requests at Job Close
Your tech just came out of a 130-degree attic. He is not asking anyone for a favor. So the ask happens at random, if it happens at all, while the shop up the road stacks reviews every week. We automate the request at job close-out, from your number, in your name, when the customer is happiest — and every new review helps the next first call book.
THE FIRST 30 DAYS
THE FIRST 30 DAYS
All four systems are built in 30 days. You see results reported against your own starting point.
Week 1
Capture & baseline
Missed-call text-back and review requests get built. We record where you're starting, so every result is measured against your numbers, not ours.
Week 2
Estimates out
Your unsold estimates get cleaned up and worked. You approve every word before anything sends.
Week 3
Past customers
Your customer list gets sorted by equipment age and lapsed agreements, and seasonal outreach goes live.
Day 30
The first report
Booked jobs and booked revenue, each one traced to the call, estimate, or customer it came from.
WE DO IT BACKWARDS
Most agencies start you at ad spend on day one, which means you are writing two checks, theirs and the platform's, before you have booked a single job.
We start with the work already in your business. No ads before Day 60, and only if the weekly reports show the system working and your crew can take on more.
If you need ads at all, they get paid for by work the system already booked, not by your savings.
GROWTH YOU CAN SCHEDULE.
WHAT YOU CAN COUNT ON
All four systems live and reporting within 30 days of access, or your build fee comes back. Conditions in writing.
Month-to-month. Thirty days' notice. Everything we build stays yours.
One page every week: calls rescued, estimates re-engaged, booked jobs and booked revenue against your own baseline.
One named person who reads every conversation. Every message goes out from your number, in your name, in wording you approved.
Your CRM stays. We work alongside ServiceTitan, Housecall Pro, Jobber, or a spreadsheet.
What we don't do: sell leads, run ads before Day 60, replace your CRM, or promise you a dollar amount.
BUILT FOR RESIDENTIAL HVAC CONTRACTORS
Whether your work comes from referrals, repeat customers, Google, or ads, it ends up in the same places: a call, an estimate, a customer record. That's where we work.
If you've got a year of estimates in a folder and nobody whose job it is to call them back, we should talk.
WHO YOU'RE WORKING WITH
ABOUT US
I'm Ozzie, founder of Plenum.
I spent over two decades in airline operations, load planning, network planning, and managing flight operations across some of the busiest hubs in North America. That work runs on one principle: good outcomes aren't left to chance. A plane doesn't get loaded on hope. It gets loaded on a system that works every time.
It's the same problem you have. Right equipment, right place, right time. An empty seat is gone at five o'clock the same way an unsold truck-hour is, and neither one comes back.
Most HVAC marketing runs on hope. Boost a post, run an ad, cross your fingers, pray the phone rings. Plenum was built to do the opposite, to go after the work already sitting in your business. The estimates that didn't close. The calls nobody caught. The customers who bought from you once and never heard from you again.
The best contractor in town shouldn't lose to the one with the biggest ad budget. Usually it isn't the work that loses it. It's what leaks out the back while nobody's watching.
That's what we fix. Every account has one person who owns it and knows your numbers, not a support queue, not a rotating account manager.
