For contractors and service pros

You did the work right. In three years nobody can tell.

The invoice goes in a drawer. The next tech has no idea what you found. The homeowner cannot remember which company they called. Every system you install or service gets a signed record that stays with the home for good, with your name on it, whether that is a furnace, a panel, a roof, or an attic full of new insulation. You know what is in that house, what you did to it, and what is about to give out, so nobody you serve gets caught without heat in January. Free to start, nothing to change on the truck. Furnaces, air conditioners, heat pumps and boilers. Water heaters and tankless. Panels, sub-panels and service entrances. Solar, storage and EV circuits. Pool and spa plant, irrigation and backflow.

The problem

Nobody knows the tank is on borrowed time.

A twelve year old water heater in a finished basement. A furnace with a heat exchanger someone flagged two winters ago. An air conditioner nobody has touched since it went in. You saw it. You wrote it on a work order. That paper is gone, the sticker peeled off, and the next person through the door starts from nothing.

Requests, without the phone call

Stay connected to your customers without having to answer a call.

When something goes wrong, your customer taps request on the system itself. It reaches your console, not a voicemail, and you decide whether to take it. Nothing is assigned to you and nothing routes around your office. Only shops connected to that property are asked.

And it arrives with the answer to every question you would have asked on the phone. The unit, its age, what it scores and why, the last three visits and who did them, what the readings say is trending, whether it is still under warranty, and what the customer says is happening in their own words.

You know exactly what is happening before you pick up a wrench. No guessing at a make from a description, no sending someone with the wrong ticket, no truck roll to find out it is a part you did not bring. Set your crew as taking work for the week and requests come to you; leave it off and they do not.

Why your customers are already here

Their first report is free. Your work is what is on it.

Any homeowner can bring us the invoices and permits they already have and get a full scored record of their house at no cost. Most of that paperwork has your name on it, because you are the one who did the work.

So the record starts with your history already in it. When you connect to a customer, you open a job knowing what is in the house, what you flagged last time, and what is still under warranty. You are not rebuilding the story every visit, and neither is the next tech you send.

It also means the homeowner has a reason to keep their record current, and the only way it stays current is if the work going into it is logged. That is the part you get paid for.

What changes

Three things change for the people you serve.

No surprise failures

You see it coming, they do too

A unit past its service life, or one with a part trending badly, shows up before it quits. Your customer replaces it on a Tuesday in September instead of at midnight in a cold snap.

No repeating the same diagnosis

Your tech arrives already knowing

Whoever shows up sees what was installed, what was fixed, and what keeps coming back. No customer pays twice for the same discovery, and nobody re-diagnoses a fault three techs already found.

No lost paperwork

Their warranty survives the move

Install dates, model numbers and warranty terms stay with the house. When a claim comes up, or the home sells, your customer has the paperwork instead of a peeled label and a guess.

Log from the field

Nothing changes on the truck

Your techs log and sign the work from their phone, on site, using your checklists or ours. No new office software, no paperwork back at the shop.

The field app

Your techs log it on site, in seconds.

Your crew opens the field app on their phone, finds the property in the registry, and signs the service right there. Readings, parts, photos, done before they pull out of the driveway. That signed record is what every screen in your console is built on.

No more showing up blind

Walk in already knowing what happened last time.

When a homeowner or building grants your shop access, every registered system shows up in the field app with its full service record. Your tech sees what was installed, what was fixed, and what keeps coming back, before they ever open a panel.

Faster diagnosis, less time spent guessing at history
Fewer callbacks, because the fix is right the first time

The homeowner owns it, you're on it

The record belongs to the homeowner, and your name stays on every system you touch for the life of the unit. That is what brings the call back.
