SmartZone is great opportunity for DISTRIBUTORS.

There are many reasons that distributors should take a look at stocking SmartZone, but basically because they can make more money & have a higher customer satisfaction with a very low up-front investment.

  1. Only 2 models needed to cover all applications.
    A lot of manufacturers require stocking 5,6... even dozens of different products to get the best price.  With SmartZone, you only need the SmartZone-2 and the SmartZone-4X.  That's right, only 2 models will cover everything from 2 zones to 20 zones, single & multi-stage, gas/electric & heat pump (including dual fuel).  As a bonus, the SmartZone-4X has built-in Fresh-Air control.
     
  2. Best wholesale pricing.
    Options for small and large volume distributors with 30 day NET terms pending credit approval.  Start with a small order or only 10 zone controllers.  Contact ECOJAY (www.smartzoning.com) for details.
     
  3. Documentation & training.
    Ecojay is committed to supporting distributors with documentation, signs, marketing materials, phone & online support.  Ecojay will even do an in-person training for contractors at new distributor locations (minimum order required for free training - normal price for training $500)
     
  4. Increase zone control profits & sales.
    SmartZone has allowed many of our distributors to increase sales of zoning because it is so much easier for contractors to use & install... they buy more.  Distributors of SmartZone also have increased margins on the higher-end controllers because SmartZone-4X can do everything the Honeywell HZ432 can do at a much lower price.
     
  5. Contractors will love you for it.
    Even contractors that "don't do zoning" occasionally come across a system that needs it or a customer that wants it.  SmartZone is the best the the occasional zoning contractor or the contractor that does it every day.  Most contractors that try it, don't want to use anything else.


Right now, only about 25-35% of the US has physical distribution of ECOJAY products, specifically SmartZone.  This is a HUGE missed opportunity.  Online distribution reaches nationwide, but even this is in it's infancy.  SmartZone deserves to be on the shelf of your local distributor and contractors deserve to have access to it.  Right now it is available on Amazon.com, Ebay, ZoningSupply.com for contractors in the US & Canada to have in a couple of days shipping time.

It would be great if some of the large online supply houses like ... Supplyhouse.com or AlpineAir.com would stock SmartZone so it could be purchased and shipped along with systems.  Or some of the national-chain distributors like Johnstone would also carry SmartZone for the sake of availability and exposure to SmartZone style zoning.

SmartZone is not a new gimmic in zoning, it is simply the BEST traditional forced-air zone control board that is available.  SmartZone has been designed with the HVAC contractor in mind and it shows with the feedback that is received over and over again from contractors.  SmartZone has been shipping since 2004 and has had rave reviews from the beginning. 

Contractors that never liked zoning before even love SmartZone.  Many of the problems that people had 10 or 15 years ago with zoning such as freezing coils or short cycling have been solved by more sophisticated zone controls but SmartZone made it simple.  Using Ecojay SmartZone makes zoning simple.
