At a national gathering of energy efficiency leaders, Midea introduced its newest heat pump technologies and took part in important discussions on accelerating the adoption of sustainable HVAC solutions across the U.S.

The certification process involved a thorough review and rigorous evaluation of Nationwide Boiler’s welding procedure by a review team from the National Board.

The survey, which included responses from over 200 CEOs, CFOs, and CSOs across various industries in July 2024, also highlighted the impact of government incentives on sustainability plans.

Exhibitors and organizers are excited to welcome thousands of HVAC contractors and other industry personnel to Chicago for the AHR Expo.

In this month’s troubleshooting situation, you are responding to a customer’s complaint that their walk-in cooler “isn’t cooling enough.”

In this month’s troubleshooting situation, you are responding to a restaurant manager’s call for service, and the equipment is a walk-in freezer.

Refrigerated Solutions Group and Budderfly announced the results of energy efficiency pilot projects across two Subway restaurant locations using RSG’s Capsule Pak ECO™.

Repairing reach-in coolers and freezers with electronic temperature controllers can be challenging at times.

Comprehensive troubleshooting can help technicians determine whether the compressor is working properly.

If a potential relay is malfunctioning, the compressor motor is in danger of not starting, stalling, locking rotor, or even burning out. That is why technicians should understand how to troubleshoot potential relays.

Learning how to troubleshoot a system that is experiencing leaky valves or worn rings can be challenging, so technicians need to take careful measurements in order to isolate the problem.

Consumers just want their A/C system fixed. It’s time to take off the contractor hat and put on the consumer hat.

Getting the right people on the team has always been essential for any company, in any industry, and HVAC is no exception.

HVAC contractors have to focus on recruiting and retaining technicians by focusing efforts on learning and then providing what the current workforce is looking for.

The question of replacing a blower versus an entire system – versus the chance something else is the real culprit – remains a case-by-case challenge.

Evapco had an exciting fourth quarter of 2017, and they used the 2018 AHR Expo to build upon that success.

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.

One of the reasons why Tecumseh regularly exhibits at the AHR Expo is for the increased visibility that it provides in the refrigeration industry.

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.

The higher the inlet water temperature, the more sensible heat must be removed from the water and the longer the freeze cycle. The latent heat removed causes the water to change state, thus producing ice.

In this puzzle, a restaurant manager complains that one of the ice machines in his high-volume establishment isn’t producing enough ice.

When the efficiency of an HVAC system is discussed, proper ductwork is often overlooked. But at the AHR Expo in Las Vegas, it was discussed plenty at the Johns Manville booth.

AI tools, such as Bluon’s MasterMechanic, could make a big dent in another aspect of the labor issue: the wisdom lost as older, highly skilled workers leave the industry.

Software company Bluon is betting that artificial intelligence, or AI, can help solve the labor shortage — and pass along decades of knowledge from retiring HVAC techs to the next generation.

The latest version of the ProMaster work van from Ram, the truck division of Stellantis, offers many features previously only available on consumer vehicles.

Software can increase productivity, better manage labor, encourage retention, and keep things consistent and organized. But it’s up to HVACR contractors to choose the right software and take the proper stops to implement it.

The ACHR NEWS caught up with Johnson Controls’ “Game On” Roadshow at its final stop in Rochester Hills, Michigan.

Refrigerant leaks in HVACR equipment – particularly commercial refrigeration systems -- are a significant problem.

The Refrigeration Showcase educates contractors about new refrigeration products, so they can help customers make the right choice.

The equipment and components in this showcase are designed to appeal to both end users and the people who work on them in the field.

The Showcase is designed to educate contractors about the new commercial and industrial refrigeration products available.

From ice machines to reach-ins to controls to components, the Showcase is designed to educate contractors about the new commercial and industrial refrigeration products available, so they can help their customers make the right choice for their application.

The NEWS introduces the latest cooling equipment available for summer 2022.

The ACHR NEWS is featuring the industry’s latest commercial cooling products for 2022.

In this showcase, The ACHR NEWS will introduce the newest cooling products that will help meet customer needs.

The annual Commercial Cooling Showcase highlights state-of-the-art equipment that often incorporates service-friendly features for contractors, as well as energy efficiency and comfort for end users.

Commercial cooling equipment manufacturers are introducing HVAC systems that are energy efficient, as well as service friendly for contractors.

A recent survey done by Daikin shows what state leads the globe in a/c usage.

How does a tech know the a/c compressor he or she is diagnosing is actually failed and that the problem is not a crankcase heater, condenser fan, or rubbed out wire?

One Stop Cooling studies technicians’ readings recorded on service calls. If you do the same, you might be surprised with the mistakes you find.

Thermostat manufacturers say they have the studies to show that the use of their smart, connected thermostats can help homeowners save on their HVAC-related energy costs.

The NEWS’ annual Cooling Showcase has traditionally introduced the latest air conditioning units available for the upcoming summer season. The intent is to help contractors prepare for this busy period by doing the research that will help them to distinguish between brands. In this issue, we focus on the commercial side of the air conditioning industry.

It’s time again for the Commercial Cooling Showcase. The NEWS’ annual issue has traditionally introduced the latest air conditioning units available for the upcoming summer season. The intent is to help contractors prepare for this busy period by doing the research that will help them distinguish between brands.

HVAC manufacturers share their latest heating products — including photos, specifications, warranty info, and more — in this detailed showcase.

Once only found in mild climates, the technology now stretches across the U.S., thanks to advances in inverter technology and zone controls. On the other hand, the level of sophistication in these systems sometimes makes them difficult to troubleshoot when something goes wrong.

An HVAC solution was the headliner for an event on Feb. 19 at a 121-year-old building in the nation’s capital named after one of America’s greatest composer-musicians. The event at Duke Ellington School of the Arts demonstrated how stepping beyond traditional non-inverter HVAC systems can preserve a building’s historical architecture, enhance energy efficiencies, minimize noise, and earn design-award accolades.

The equipment in this month’s troubleshooting situation is a split system that has only been in service for two years, but there is a lot of history.

The EEV is often used in modern refrigeration systems, but troubleshooting its common failures may be complicated.

Troubleshooting refrigeration systems can be complex and frustrating, so put aside any assumptions and inspect the system thoroughly before making any diagnosis.
