Parker Hannifin Corp. addressed two of today’s most pressing HVACR issues ― a labor shortage and pandemic-fueled concerns about indoor air quality (IAQ) ― during the recent AHR Expo.

Among the various HVAC insulation options available, elastomeric closed-cell foam duct insulation (closed-cell foam) solutions stand out for providing safe, sustainable, high-performance thermal and acoustic insulation while resisting moisture and improving overall indoor air quality (IAQ).

"Baking the cost of a humidifier or dehumidifier into a full system offering is the trend today,” said Tom Ruse.

It has now been two years since the pandemic brought IAQ to the forefront of everyone’s minds. Manufacturers are stepping up with an array of products to clean and monitor the air people breathe.

Homeowners are increasingly paying attention to improving their indoor air quality, and dehumidification is a big part of the IAQ equation.

Following are several of the latest dehumidification products on the market, representing residential and industrial applications alike.

The Sensedge Go monitors up to 14 indoor air quality and environmental parameters, providing comprehensive insights into all aspects of the built environment.

The EERS required Indiana’s electric utilities to cut energy delivery by an average of 2 percent annually, as well as providing home energy assessments, low-income weatherization, and efficiency rebates for businesses, homeowners, and schools. In 2014, Indiana legislature passed SEA 340 to cancel the EERS. Then Gov. Mike Pence did not veto or sign the bill, so it became law, and Indiana became the first state to repeal its energy efficiency standard.

Digitalization is a technological paradigm shift that is transforming our lives, and is set to have a compelling impact on the cold chain.

If an HVAC contractor possesses knowledge pertaining to IAQ solutions and how to approach the subject with a homeowner, they are in a good spot to sell the equipment.

With the recent surge of interest in IAQ options, consumers might easily forget that those components must still work within a system.

Manufacturers in the realm of IAQ are seeing an uptick in interest due to increased awareness among consumers as well, as the air quality concerns that come as a byproduct of efforts to tighten up buildings to increase energy efficiency. In response, they’ve been updating IAQ products for the age of the smartphone and the “smart” HVAC system.

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

At the 2020 AHR Expo, Broan-NuTone introduced Overture, a fully automated, cloud-connected, whole-home IAQ system that monitors and optimizes air in the home.

Responding to increased public awareness of the importance of healthy indoor air quality, the hospitality industry is stepping up its game when it comes to providing guests with fresher, cleaner, and, sometimes, sanitized indoor air.

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

How can an effective airflow strategy ensure quality ventilation and optimal indoor air quality, without breaking the budget?

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

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.

Packaged rooftop units are the workhorses of the commercial market, providing cooling to approximately 60% of U.S. commercial building floor area.

Andy Kelso was named COO; Shane Lawrence, CFO; Brinnon Williams, vice president of residential business; and David Archer, vice president of commercial business.

Many of Fujitsu General America’s Halcyon mini-split system products now qualify for Energy Star Most Efficient certification.

As HVAC providers, we have the ability to advise homeowners, builders, and property managers on ways to improve their indoor air quality.

The proper application of modern HVAC technologies can help maximize indoor air quality while minimizing losses in operational efficiency.

After six meetings, the working group reached consensus and provided recommendations for energy conservation standards, test procedures, and metrics.

Since they don’t have to stay in one place, portable cooling units have been known to show up in some pretty unique places. Here’s a closer look at how portable units are serving in some outside-the-box applications.

Today’s commercial structures are full of sophisticated controls that have been changing building automation systems exponentially.

The exodus of users away from Twitter and Reddit has led many of those information refugees to discover the joy of subscribing to feeds in a reader. RSS and Atom feeds are an enormous open decentralized network that can never be ruined under new ownership -- because there's no owner.

Tara Calishain of ResearchBuzz has written a 4,000-word introduction to RSS for people who are new to the world of feeds:

I could not do ResearchBuzz without RSS feeds. They're invaluable. And I think if you learn more about them, you'll appreciate why I consider RSS the most underrated tech on the Internet. That's what this article is about: I'm going to explain what RSS feeds are, show you how to find them, go over some of the RSS feed readers available, and, finally, list several tools and resources you might find useful on your journey.

... I follow over a thousand RSS feeds which deliver information to me throughout the day. Do you think I could visit a thousand websites a day to check for new information? Even if I tried to visit a thousand a week that would be over 142 websites a day. Assuming it took me two minutes to visit a site and check for new content, I would spend over 4.5 hours a day just visiting websites.

Do you see why I'm so grateful for RSS?

Calishain, who was blogging before Netscape created RSS in 1999, covers a lot more than the basics, showing how to find hidden feeds on websites, check a bunch of feeds for freshness and create keyword-based feeds to search sites like Google News, Hacker News and WordPress. Even experienced readers of readers will learn new things, and there's a collection of nine handy RSS Gizmos she has developed.

On that subject, Calishain just began programming a year ago:

In spring 2022 I decided to find out if I could really learn JavaScript after being diagnosed as autistic. (I'm a high school dropout and didn't think I could learn something like programming.)

I CAN! And I LOVE IT!

Welcome to the not-so-secret society of programmers, Tara! Please slow down a little. You're making the rest of us look bad.
