AHR Expo 2025: Innovation, Insights, and Industry Connections in Orlando

Last week, we had the incredible opportunity to attend the AHR Expo 2025 in Orlando, Florida—one of the HVACR industry’s most significant annual gatherings. This event brought together manufacturers, engineers, contractors, distributors, and industry leaders from around the world to showcase the latest innovations, discuss key industry trends, and forge valuable business connections.

Held at the Orange County Convention Center, the expo was a sprawling hub of cutting-edge technology, networking opportunities, and insightful education sessions. From the moment we stepped onto the showroom floor, it was clear that this year’s event was set to be one of the most dynamic yet. The energy was electric, with thousands of attendees exploring booths from more than 1,600 exhibitors, each showcasing groundbreaking products and solutions aimed at driving the HVACR industry forward.

One of the key highlights was seeing firsthand how the industry is embracing sustainability and energy efficiency. With increasing demand for environmentally friendly solutions, many exhibitors unveiled high-efficiency HVAC systems, advanced building automation technologies, and new refrigerants designed to meet evolving regulations. Smart building solutions were a major theme, with numerous companies demonstrating how IoT and AI-driven systems are enhancing climate control, optimizing energy usage, and improving system diagnostics.

Our team took full advantage of the opportunity to connect with both new and existing partners. The expo provided an ideal setting to strengthen relationships with suppliers, discover new technologies, and gain insights into emerging trends that will shape the industry in the coming years. We were particularly impressed with innovations in smart zoning solutions, advancements in heat pump technology, and improvements in indoor air quality (IAQ) management—all of which are critical to the future of HVACR.

Beyond the exhibitor floor, the AHR Expo also featured a robust lineup of educational sessions, keynote speakers, and industry panels. We attended several thought-provoking discussions on topics ranging from decarbonization efforts to the future of smart HVAC systems. The conversations around workforce development and the role of technology in addressing labor shortages were particularly insightful, reinforcing the need for continued investment in training and upskilling.

Of course, an event like this isn’t just about business—it’s also about community. Whether it was reconnecting with long-time colleagues, engaging in lively discussions at networking events, or simply sharing a coffee with fellow industry professionals, the AHR Expo reminded us of the passion and innovation that drive this industry forward.

As we wrap up our time in Orlando and reflect on everything we experienced, one thing is clear: the future of HVACR is bright. The technologies we saw, the discussions we participated in, and the connections we made will all play a crucial role in shaping our strategy for the coming year. We left the expo feeling inspired, informed, and excited for what’s ahead.

Is Zone Control really for everyone?

Why Your Residential and Light Commercial Forced-Air Systems Need a Zone Control System

In today's world, energy efficiency and personalized comfort are top priorities for homeowners and business owners alike. One technology that can significantly improve both is a zone control system for your forced-air heating and cooling systems. At ZoningSupply.com, we believe that implementing a zone control system, such as the SmartZone from Ecojay, can transform how you experience comfort in your home or business. Here’s why.

Understanding Zone Control Systems

A zone control system divides your home or business into different zones, each of which can be heated or cooled independently. This is achieved through the use of dampers installed in the ductwork and controlled by a central system that responds to separate thermostats placed in each zone. This allows for precise temperature control in different areas, leading to numerous benefits.

Benefits of Zone Control Systems

1. Enhanced Comfort

With a zone control system, you can maintain different temperatures in different areas of your home or business. For example, you might prefer a cooler bedroom at night but a warmer living room during the day. Zoning allows you to set the perfect temperature for each zone, ensuring optimal comfort for everyone.

2. Energy Efficiency and Cost Savings

Heating or cooling your entire home or business uniformly can lead to wasted energy and higher utility bills. Zone control systems reduce energy consumption by only conditioning the areas that need it, rather than the entire building. This targeted approach can lead to significant cost savings over time.

3. Extended HVAC System Lifespan

By reducing the workload on your HVAC system, zone control can help extend its lifespan. Since the system isn’t working as hard to maintain a uniform temperature throughout the entire building, there’s less wear and tear on the equipment. This can result in fewer repairs and a longer life for your system.

4. Improved Indoor Air Quality

Zone control systems can improve indoor air quality by ensuring that the HVAC system is not overworking and potentially spreading dust, allergens, and other pollutants throughout the entire building. By focusing on specific zones, it’s easier to manage and maintain cleaner air.

5. Customization and Control

Modern zone control systems, like Ecojay's SmartZone, offer advanced customization and control options. You can easily set schedules, make adjustments remotely, and monitor system performance, all of which contribute to a more efficient and user-friendly experience.

Why Choose Ecojay's SmartZone?

Ecojay's SmartZone system stands out in the market for several reasons:

1. Advanced Technology

SmartZone utilizes advanced technology to ensure precise control and efficient operation. Its intelligent algorithms and user-friendly interface make it easy to customize settings for optimal performance.

2. Easy Integration

3. Reliable Performance

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.

View fullsize

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.

HVAC Contractors: Out-Perform the Competition with ZoningSupply.com

Contractors nowadays are finding that homeowners and business-owners are looking for all the bells and whistles they can reasonably afford and install. Among features like energy-efficient fixtures and home-automation, HVAC zoning is usually near the top of this list. Of course, zoning offers multiple benefits to homes and buildings as it can save energy and provide a custom level of comfort.

As HVAC zoning rises in popularity, homeowners and business-owners are beginning to ask for it by name.

How can contractors make the most of this movement?
It starts with choices. Many contractors have unfortunately limited themselves to zone control systems that sit at the top of the market (as well as the top of the price-range.) This would be great if these “name-brand” zoning systems offered quality, reliability and features that justified the price. This is simply not the case. Contractors who have worked with zoning for a while can attest to this. The good news is that there are now many choices when it comes to zone controls, dampers, and equipment. Contractors and suppliers can now sift through the choices and figure out which systems are the simplest to install, the most reliable, and provide the best customer support.

This is where ZoningSupply.com comes in. ZoningSupply guarantees their products to be the most reliable, the easiest to install, and the most affordable in the marketplace. Hundreds of contractor and homeowner testimonials over the past 10+ years sing praises of the top-notch products they offer.
Here’s why . . .

Contractor-Friendly
The engineers behind ZoningSupply products will tell you that their systems were designed with the contractor in mind. In other words, full-color install guides, screwless wiring, and color-coded LEDs are only the start. If a contractor picks up the phone and talks to Jeff or one of our other tech-support specialists, they’ll be sure to have all of their questions answered quickly but thoroughly.  

Easy-to-follow instructions and simple design make for a lightning-fast install.  

Ship Direct for Free
Furthermore, ZoningSupply.com can ship anywhere in the U.S. for free. Individual components or entire systems can be purchased on the website and delivered straight to your office or job site,  

Affordable
ZoningSupply’s featured SmartZone 2x, 4x, and 2L systems are among the most affordable in the marketplace. This puts money in your pocket and provides savings that can be passed along to homeowners.

Universally Compatible
If a contractor uses ZoningSupply, they can confidently offer retrofit options for virtually any existing HVAC system on the market. This means not having to learn and re-learn various installation procedures. This also means that nearly every home or building in your area can be retrofitted for zoning . . . Think of the opportunities!

With zone control systems, as with any product, there are the good, the bad, and the ugly. In the end, they all must answer to the contractors and ultimately the homeowners. When bidding on projects or marketing their services, contractors should equip themselves with the confidence and reliability that ZoningSupply.com products provide.
