When faced with a leaky coil on a reach-in cooler, a decision needs to be made whether to repair or replace it. The final decision may come down to where the leak is located.

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

Although CO₂ systems may seem a bit more complicated than HFC DX systems, they are actually quite similar, with the main difference being CO2’s higher pressure.

How do we motivate HVAC contractors to do more refrigerant recovery? The ACHR NEWS posed the question to three industry experts on the front lines of the refrigerant transition. Here’s what they had to say about what that will take — and what we’re all going to be in for if we don’t.

CO₂ refrigeration, which has gained significant traction in ice arenas and supermarket coolers, is now emerging as a groundbreaking technology revolutionizing the way we cool and heat across industries worldwide.

New HVACR cooling innovations promise to enhance sustainability and improve energy efficiency. 

A new technology has been developed that can decompose refrigerants, using a catalyst made from industrial waste called “red mud.'’ 

As the industry continues to evolve, it’s essential for HVACR contractors to embrace comprehensive training programs that address both foundational knowledge and hands-on experience with CO₂ systems.

In this episode, The ACHR NEWS speaks with Andre Patenaude from Copeland about some of the current issues that are shaping the commercial refrigeration industry.

New cooling technologies that promise to revolutionize the way climate control is approached are emerging in the HVACR industry.

Chillventa 2024, held Oct. 13-15 in Nuremberg, Germany, showcased some of the world’s most innovative technologies to more than 33,000 attendees from 49 countries. Through more than 250 presentations, visitors were privy to the latest developments driving innovation throughout the HVAC industry.

HB 738, introduced Oct. 4 by Rep. Niraj Antani (R-Miamisburg), requires the Ohio Facilities Construction Commission (OFCC) and the Department of Education (ODE) to study the status of school buildings regarding air conditioning, accessibility, and school safety.

Seven of the new full-time employees hired to start up operations previously worked at the VISE-GRIP factory. Malco plans to add jobs as production increases.

Gov. John Kasich and the legislature targeted funding in the state capital budget to assist Ohio’s public universities, community colleges, and career technical centers in providing the most up-to-date education possible, part of an effort to provide a skilled workforce for in-demand jobs.

A compressor design proposes a new drive mechanism for compressors used for cooling in homes, buildings, airplanes, and cars.

Condensing units that are exposed to low ambient conditions must have some sort of low ambient control installed on them.

Performing a more detailed inspection of a compressor might reveal a system issue that could lead to a failed compressor.

Little by little, a compressor’s lubricating oil will eventually escape the compressor’s crankcase and enter the system’s tubing.

Compressor manufacturers have been improving the products on multiple fronts in recent months.

When electrically inspecting or troubleshooting a compressor, you should always protect yourself against the possibility of terminal venting.

Any compressor that gets too hot or is overheated is subject to premature wear between its internal moving parts.

Any compressor that gets too hot or is overheated is subject to premature wear between its internal moving parts.

The first step consists of determining the compressor’s mode of failure. Was it electrical or mechanical?

Have 166 years of small improvements and occasional leaps in chemistry taken us to the limit of what compressors can do?

Airflow is one of the leading causes of failure for compressors.

Even though the circulated refrigerant is the working fluid required for cooling, lubricant or oil is needed for lubrication of the compressor’s moving mechanical parts.

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

There are a few different things HVAC contractors can check to ensure proper compressor function. This article highlights seven of them.

At its press conference at the AHR Expo, LG Electronics Component Solutions highlighted its new compressors for residential applications that will utilize the low-GWP refrigerants.

End users are looking for more from their systems than just reliable cooling; they also want sustainable equipment that features better energy efficiency and low-GWP solutions. Several compressor manufacturers have happily obliged.

HVACR systems consume a significant amount of energy, which leads to increased carbon emissions. Manufacturers have found that the variable-speed compressor may be the solution to this problem.

Ross B. Shuster, CEO, Copeland, discusses Blackstone’s investment into the company, how the transaction will impact the company’s HVAC offerings, and more.

More than 130,000 Danfoss Turbocor compressors have been installed around the world.

Compressors in A2L systems are similar to A1 systems, so technicians won't need extensive retraining, especially if they follow best practices.

Continuous and rapid cycling is hard on a compressor, but the use of a simple time delay relay can mitigate the risk of compressor failure.

End users are looking for low-GWP solutions, and compressor manufacturers displayed their options at the AHR Expo.

The move to A2L refrigerants means compressors in new a/c and heat pump systems will have different features than older models. Three compressor manufacturers say they’re prepared.

Read this white paper to learn more about why variable-speed compressors are the best solution for heat pump applications.

“We put together some sections of 2 ½-inch pipe, and Joe tried to drive a nail through them with a hammer. I remember him reporting back and saying, ‘This is not your typical plastic.’”

Complex buildings come with increasingly unique requirements, including the vital aspect of climate control.

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

There has been debate on the transition from traditional a/c units to the smaller ones, or to find other worthy alternatives.
