Frequently Asked Questions
How do I share my referral code?
Simply tell potential clients: "Contact ProCalcs for your HVAC design needs and mention referral code [YOUR CODE]." They can call, email, or use the website.
When do I get paid?
Commission is paid after the referred project is completed. We'll contact you to arrange payment.
Is there a limit to how many clients I can refer?
No limit! Refer as many new clients as you'd like.
What services qualify for commission?
The first project from each new client referral, including Manual J load calculations, duct design, and energy calculations.
Do I earn commission on repeat business from my referrals?
Commission is paid on the first project only for each new client you refer. This keeps the program simple and straightforward for everyone.
What qualifies as a "new client"?
A new client is someone who hasn't previously worked with ProCalcs. If they're already in our system or have done business with us before, they wouldn't qualify for referral commission.
What if my referral doesn't mention my code?
We always ask new clients how they heard about us. If they mention your name or company, we'll credit you. But having them use your code ensures proper tracking.
Do I need to be a current client to join?
No! We welcome referral partners whether you've worked with us before or not.
What if I want to leave the program?
No problem! Either party can exit the partnership with 30 days written notice. There's no long-term commitment.
