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.

AI-enabled HVAC systems can offer benefits for building owners and occupants. By monitoring and analyzing conditions inside a space, as well as outdoors, the system can constantly make adjustments to the environment based on the data being collected.

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

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.

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.

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

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

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

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.

Sensibo produces smart heating and cooling devices and IAQ monitoring products, allowing users to control their heating and cooling equipment with artificial intelligence, data, and sensors, while taking advantage of air quality data to optimize equipment use and reduce energy consumption.

Residential air movement and ventilation can be a challenge that requires multiple callbacks. There is a way to fix that, though.

This time, the conversation turns to duct sealing and what it means in terms of system efficiency and energy savings.

Properly sealing and maintaining heating and cooling ducts is a low-cost measure that can improve energy efficiency.

By employing a ventilation strategy such as a DOAS, conditioned fresh air can be brought into the building, thus improving IAQ and ensuring a safer environment.

Diverse examples show the importance of air movement and the creative ways in which contractors and manufacturers have dealt with it successfully.

In the end, it's about airflow control. Unless your solution involves airflow and pressure measurement, you're guessing whether the repair worked.

Many homeowners may underestimate the importance of proper ventilation, which a lack of could cause discomfort and higher energy bills.

Many in our industry believe the duct material used in an installation determines how well the HVAC system moves air. The issue isn’t the material type, it’s how we install the product.

My advice is simple: Don’t be afraid to pursue this industry if you have a passion for it. The HVACR field is full of opportunities, and your technical skills, creativity, and leadership can make a significant impact.

AI promises to revolutionize IAQ, but first, it needs to overcome several challenges, like unreliable data, incomplete automation, and gimmicky solutions that fail to deliver real value.

HVACR distributors today are introducing software to meet contractors where they’re at and to fit the way they place electronic orders. At the same time, they’re working to maintain the personal relationships they’ve built with those customers.
