The Best HVAC Estimate App for Solo Contractors (2026)
Send professional quotes from your phone in 60 seconds. E-signature included. Try free — no card required.
Create branded estimates from your truck. Send a link. Know when they open it. Get the signature. No paperwork, no chasing.
You do great work. Your proposal doesn't show it.
52% of HVAC contractors still don't use any software. They send quotes by text or scribbled on the back of a card. Homeowners compare three or four bids — and the one that looks professional and arrives fast wins. The average job lost to silence is worth over $3,500.
Your competition isn't cheaper. They're faster. An HVAC estimate app that lets you send a real proposal in 60 seconds — and know the second the customer opens it — turns you into the contractor who gets the callback.

Contractors Who Switched. Jobs They Won.
I sent my first quote through BidLock on a Monday morning from the parking lot. Customer signed it before I got to my next job. I've never had that happen with a text message.
I track every quote now. Last month I followed up on two quotes that had gone quiet — closed both of them. That's $6,800 I would have left on the table.
