A ban on the installation of natural gas infrastructure in new buildings is coming soon to a town near you, and the local HVAC industry needs to be prepared — or maybe not.

Home builders need to begin preparing for the big refrigerant shift that is quickly approaching.

I made a comment about pairing larger-tonnage fans with smaller-tonnage outdoor units that has drawn a lot of interest.

Current trends are pointing toward unprecedented technological advances in the air movement sector.

Here’s an answer for contractors wondering, “How do I effectively sell air movement and ventilation efficiency, and why should I?”

Airflow takes the path of least resistance through buildings, often leaving much of the air stagnant and unaffected. A new IAQ strategy is needed.

Rated for indoor and outdoor covered spaces, this fan can cover up to 23,000 square feet.

This product features multicolored Chroma LEDs that allow users to choose from 24 hues with the included wall control.

Hunter Industrial, a division of the Hunter Fan Company, has donated and installed two HVLS fans to DCI Logistics.

Awarded the Energy Star® Most Efficient Mark in 2019, this product has a high-efficiency DC motor.

HVLS fans offer an affordable and effective solution for large-scale ventilation, as well as demonstrating success in smaller applications.

In the right situations, whole house fans provide a good option to homeowners who want to avoid running air conditioning all the time.

Filter fans perform a critical task of cooling equipment within electrical enclosures while also protecting equipment from harmful materials.

Superseding AMCA Publication 511-21, AMCA Publication 511-21 (Rev. 12-22) outlines technical procedures and the proper presentation of data for the certification of air-control devices through the AMCA Certified Ratings Program (CRP).

Frost on an evaporator coil will prevent the correct amount of airflow across the coil. Anytime the evaporator coil experiences reduced airflow across its face, there will be a reduced heat load on the coil.

Nothing lasts forever. This old adage holds true, especially when it comes to HVAC coils.

Once considered a temporary solution, portable heating and cooling units continue to evolve as consumer demand calls for new units and new uses.

The York^® Mission Critical Direct Evaporative Cooling (DEC) Air Handling Units (AHUs) from Johnson Controls Inc. are designed to meet data centers’ specific needs.

This unit is a semi-custom fabricated air handler that can utilize direct or indirect evaporative cooling or a combination of both to meet specific usage and dimensional requirements.

The future of classroom environments just got a little quieter, thanks to the recent certification of Changeair’s Freshman Series Vertical Air Handler by the Air Movement and Control Association (AMCA) Intl. Inc.

Trane and Stulz USA announced a strategic OEM supply sales agreement for the United States and Canadian markets.

Heat recovery systems can be divided into two categories based on the thermal parameters of the system: Systems with high and low thermal parameters.

Delivering 1 to 1.5 tons of nominal cooling, this formerly single packaged unit is now a separate module.

Designing, selling, and producing AHUs is a long process. Is there anything we can do to accelerate the process?

One-year study conducted on Atlanta commercial high rise’s HVAC systems proves UVC lamps reap energy efficiency payback benefits.

New technology has made air handlers more efficient and much quieter, and when paired with heat pumps, a great all-electric and sustainable option.

When customers call your service company, it’s for one thing — your expertise. They don’t want a price, the problem fixed, the fast and cheap solution, etc. like many technicians think. They want good information and possibly a little guidance to make a good decision.

Here is the potential problem: A contractor quotes a customer on the compressor replacement, and he agrees to repair the cooler at the quoted price. Then, as the technician is completing the job — or even after he has finished replacing the compressor — he finds out there is another system problem.

Chris Forth, vice president of codes, standards and environmental affairs at Johnson Controls Inc., told a group of AHR attendees the industry can increase equipment installations with the help of the tax incentives and consumer rebates in the Inflation Reduction Act (IRA).

An HVAC tech was stuck on a roof as a trio of brazen thieves made off with all his tools after kicking over his ladder during a daylight heist.

Refrigeration systems can become restricted in both their high and low sides for a variety of reasons.

If a condenser coil is dirty or fouled, its ability to reject heat is severely affected.

With over 20 years of experience in natural refrigerants, Embraco’s compressor portfolio features products for commercial food service, food retail, merchandisers, and aftermarket segments. Conveniently, the booth was sectioned into these four different segments, so AHR Expo attendees could easily find the R-290 solution they were looking for.

Johnson Controls Inc. had a big 2018, with the launch of several new products and the acquisition of Lux Products Corp. For Johnson Controls, the Lux acquisition enhances its commitment to thermostats. The move also enables faster product development cycles, improves customer service capabilities, and supports greater product innovation.

Troubleshooting the high side of a refrigeration system will often give service technicians valuable information. That’s because what happens in the condenser is a direct reflection of what is happening in the rest of the refrigeration system.

Designed to maximize reliability and uptime, this product allows technicians to stay dry while safely inspecting the basin with an internal walkway.

SPX Corporation has completed the acquisition of SGS Refrigeration Inc., based in Dixon, Illinois.

A look around the world of condensers these days shows three factors driving changes.

Most outdoor units will have survived another winter intact, but nearly all will need some routine (or added) TLC to get into game shape.

Occasionally while servicing refrigeration equipment, technicians may come across a system utilizing a water-cooled condenser instead of an air-cooled condenser.

What happens in the condenser is a direct reflection of what is happening in the rest of the refrigeration system.

There are several reasons why the compressor discharge temperature of a refrigeration system can be high when the condensing temperature is not, and a checklist can help a technician figure out the root problem.

Integrated Facility Services (IFS), a full-service mechanical contractor with offices in St. Louis and Columbia, Missouri, announced it has acquired Wally’s Refrigeration, Lake of the Ozarks, Missouri.

Homes, restaurants, bars, and businesses rely on clear, clean ice for many applications. Ice is considered a food source, and the water that makes the ice must be of good quality. Good quality water will produce a crystal-clear, hard piece of ice.

Emerson Climate Technologies has filed a patent application for a simulation model of a commercial ice machine to support development of more efficient equipment that can meet upcoming U.S. Department of Energy (DOE) targets.

The U.S. commercial refrigeration systems market is projected to expand at a healthy compound annual growth rate (CAGR) of 3.2 percent in terms of value through 2025, according to a report from Future Market Insights.

This year’s Dealer Design Awards gold winning product in the Refrigeration and Ice Machine category is the Quantum Air™ Remote Air Cooled Condenser from Heat Transfer Products Group Inc.

Emerson spent more than three years researching and designing its 2018 Dealer Design Award gold-winning product in the Refrigeration and Ice Machines category.
