Why CONSTRUKTR

Why HVAC Contractors Choose CONSTRUKTR

Keep maintenance agreements on schedule

Service agreements live on the customer record with recurring billing, so seasonal tune-ups get booked and invoiced without anyone chasing a spreadsheet.

Balance emergency calls against booked work

The dispatch board flags conflicts when a no-heat call has to slot into a day that is already full, so the office can reassign without stranding a tech.

One record from the load calc to the invoice

The estimate, the job photos, the equipment installed, and the invoice all sit on the same job, so the office and the field are never working from different notes.

FAQ

HVAC software questions, answered

Straight answers to what hvac businesses ask before they start a free trial.

Is CONSTRUKTR a good fit for a small HVAC shop?

Yes. It is built for shops running roughly 1 to 15 techs, and your whole crew is included on every plan with no per-user fees. A solo operator can run the whole business from the mobile app; a shop with an office unlocks the web platform at the Pro plan.

Can my techs build estimates in the field?

Yes. The AI smart estimator turns a scope of work into a structured estimate with materials, labor, and your margin, ready for you to review, and your tech can do it from the mobile app while standing at the unit.

Does it handle seasonal maintenance agreements?

Service agreements live on the customer record with recurring billing, so spring and fall tune-up plans get scheduled and invoiced on their own cadence instead of falling through the cracks.

How does it handle emergency no-heat or no-cool calls?

The dispatch board lets the office reassign jobs with drag and drop and flags conflicts when an emergency has to slot into a full day, so an urgent call does not quietly double-book a tech.

Can I take payment when the install is done?

Yes. Your tech can capture a card payment on site through Stripe, and the payment closes out the same job the estimate started on.

How much does CONSTRUKTR cost?

There are four paid plans, Starter, Core, Pro, and Business, with no per-user fees. Every plan starts with a 14-day free trial and no credit card is required. See the pricing page for the current monthly and annual rates.
