Frequently Asked Questions
Is it really free to join?
Yes, completely. There is no registration fee, no credit card required to sign up, and no monthly subscription. When you register you receive 10 free credits — enough to place your first promotion in one app for a full month at zero cost. The optional top-up packs are only needed if you want to advertise beyond those free credits.
Who sees my deal?
EzeCalc is used by HVAC designers and contractors performing heat load calculations and equipment selection across New Zealand. Gas Cylinder Mate is used by refrigerant technicians for gas cylinder tracking, fill calculations, and compliance tools. Both are trade-specific apps — no general public traffic.
What can I advertise?
Products, services, promotions, training courses, or anything relevant to the HVAC and refrigeration trade. You write your own headline, deal details, and choose your call-to-action URL — we don't restrict the content as long as it's trade-relevant.
When does my deal go live?
Immediately after you book a slot in the Supplier Portal. You choose which month to book — current month or next month. Your deal appears in the Deals tab of the app for every user during that calendar month.
What if I want to cancel?
You can cancel a booking from the Supplier Portal. Cancellations made within 24 hours of booking receive a full credit refund. After that window the slot has been held in your name and credits are not refunded. Credits never expire so unused credits carry forward to your next booking. There are no lock-in contracts or monthly fees.
