Sell the one
thing every HVAC
contractor can't fake

Proof that the install was done right. Klosum closes out every job with the permit, the serials, the photos and the warranty registration — then hands the homeowner a certificate with your client's name on it, and yours nowhere.

Why contractors pay for this

They did the work right.
They just can't prove it.

Every one of these is money already earned and then quietly lost — after the truck has left, when nobody is looking at the job any more.

01 — THE REBATE

The discount he already gave away

Utility rebates are applied by the contractor, straight off the invoice. He discounts the job up front and gets reimbursed later — but only after the mechanical inspection is finaled. No final, no reimbursement. He gave the money away and never gets it back.

02 — THE WARRANTY

A window nobody is watching

Miss the 60 or 90 day registration and parts coverage drops from ten years to five. The failure shows up in year seven, the homeowner expects coverage, and the contractor decides whether to eat a compressor to keep his name clean.

03 — THE PERMIT

It surfaces years later, at the sale

Unpermitted work is usually discovered when the house sells. Fines run to five figures, the sale stalls, and the homeowner remembers exactly who installed it.

The product

Three screens.
That's the whole thing.

Small contractors abandon software that needs training. Nothing here does.

In the driveway

The tech finishes
the job once

A phone checklist that will not let him drive away with a hole in the record. Camera first, big targets, no typing that can be avoided.

  • Model and serial entered once, then carried onto the certificate, the rebate paperwork and the warranty record — never typed twice
  • The pairing is checked against the refrigerant rules before it goes in
  • Six required photos, and the job cannot close until they exist
  • Homeowner sign-off captured on the job before it can close

The office sees
the money, not a list

It opens with the number that matters and works down. Not a task list — a recovery queue, sorted by what is worth the most.

  • Rebate money discounted and not yet recovered, in dollars
  • Blocked jobs ranked biggest first
  • A warranty clock per install that fills as the window closes
  • Every install, every status, one table

What the homeowner keeps

The one page that
leaves the building

A certificate of installation carrying your client's name, licence and colours. It is the thing a homeowner keeps in a drawer and produces years later — and the platform is named nowhere on it.

  • Equipment, serials, efficiency, refrigerant, permit, warranty
  • The installation photographs
  • A compliance record that states what is missing, not just what passed
  • Prints or saves as PDF from any browser

Not your logo
on our product

Run the vendor-visibility test: a homeowner opens the email, visits the portal, signs the closeout and gets the PDF. Our name appears nowhere in any of it.

YOUR BRAND

Your product name

Your agency name, product name, logo and colours across every screen a contractor sees, and their own name and licence on everything a homeowner receives.

YOUR OWN ADDRESS

You set up nothing. Ever.

Your agency gets its own address the day you sign — youragency.klosum.com. No DNS to change, no certificate to buy, no server to run, nothing pointed anywhere. Your product name is in the tab and on every page. It is live in minutes, not after an IT ticket.

YOUR EMAIL

Sending identity per contractor

Each contractor carries its own sender name, address and reply-to, and its own authenticated sending domain with DKIM and SPF. Sending the certificate straight from the app is on the roadmap — today it prints or saves as PDF.

YOUR ACCOUNTS

You provision, not us

Create a contractor, set their branding, issue logins, suspend, reactivate. No ticket, no waiting on us, no per-customer setup call.

YOUR RULES

Your programs, your jurisdictions

Program name, permit authority, efficiency minimums, capacity ceiling, approved refrigerants and the A2L cutover are configuration — not code.

YOUR DATA

Theirs to take

Every contractor can export their whole record set — jobs, users, photo manifest and audit history — in one file. It removes the objection before it is raised.

Your margin

Bill them yourself,
or bill through us

You set what a contractor pays. You keep the relationship either way.

Straight answers

The questions
agencies actually ask

Will my contractor ever see your company name?

No. Your agency name and product name run across every screen a contractor sees. The contractor's own name, licence and colours run across everything a homeowner receives — the portal, the certificate and the email. Our company name is not in the tab title, the PDF or the sender address. Contractors sign in at your own address on our infrastructure — you point nothing at us and set nothing up.

Does this replace ServiceTitan, Jobber or Housecall Pro?

No, and it should not. Those are systems of record — scheduling, dispatch, invoicing. This sits on top and does the one thing they leave to the contractor: proving the installation was legal, permitted, rebate-eligible and registered, before the deadline.

What happens if a contractor leaves?

They export everything — jobs, users, photo manifest and audit history — in one file. Their records are theirs. That answer is worth having in the room during the sale.

Who supports the contractor?

You do, as their agency — that is what makes it your product. Anything that turns out to be a platform defect escalates to us.

What does it cost me?

You set what your contractors pay. If you bill them on your own Stripe we take nothing from that transaction. If you bill through the platform we keep 5% plus the card fees. Talk to us about the platform rate for your volume.
