Invented in the field

Brent Lush saw it first.

Brent runs GoodFellas Air Conditioning & Plumbing in Tucson, a family owned crew with 4.9 stars from over 1,700 Google reviews. He watched good techs lose good jobs because the homeowner couldn't see it, and watched installs go sideways because the unit sold didn't fit the space. So he drew up the fix: snap the space, drop in the unit, and let the app call it. FitCheck is Brent's idea, built by Hella, and proven first on GoodFellas trucks.

“What gets sold should be what actually fits.”

The problem

Every other tool in this trade looks like 2009.

01

Homeowners can't picture it, so they say let me think about it.

02

Techs guess if it fits. A wrong guess is a callback.

03

The software you run on was built for the office, not the living room.

How it works

01

Snap the space.

Capture the install area and set scale from one known measurement.

02

Drop in the unit.

Choose the exact model from your own equipment catalog.

03

Get the call.

FITS, TIGHT or NO FIT, with the fix your crew needs.

Hand the homeowner a plan with your name on it.

Six ways it earns its spot

Built for the whole replacement call.

Fit check

Real clearance rules show what fits before the quote is signed.

Right-size

Start with the address and flag oversized or undersized systems.

Read the old unit

Turn the data plate into age, refrigerant and urgency.

Share from the couch

A link the homeowner can review and sign with their spouse.

Plans for both sides

Print a clear homeowner plan and a field-ready installer plan.

Replacement forecast

Build the next call list from equipment seen on every visit.

Founding crews

Built with contractors, not for them.

We're opening FitCheck to a small group of HVAC shops that care how their brand looks on the truck, the shirt and the proposal. Founding crews shape the product and lock in early access.

Works with what you run

Not another CRM. The best friend of the one you have.
