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.

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.

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.

In 2017, RenewAire moved into a 110,000-square-foot building and retrofitted it as one of the nation’s few LEED Gold-certified industrial facilities.

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

Some savvy investors realize the greatest potential for helping the environment and getting a good return on investment comes from the HVAC industry.

The ductless market has grown significantly in the U.S. in the last 20 years. What was once a fringe product has become a prominent subset of the HVAC world.

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.

Each service vehicle is a technician's roaming office. It can be a source of added expense and risk, or it can be managed with resourse like GPS and data-based solutions for the safest and most profitable use. Here's a bird's-eye view of what one fleet management software company sees in its customers.

At a booth thick with traffic at the AHR Expo’s, commercial product manager Schlegel talked about Johnson Controls’ new YORK Sun Choice rooftop unit.

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

Sustainability is core to the thinking at Rheem and was a common theme throughout the AHR Expo.

The rapid expansion of data centers has raised concerns about their massive energy use and carbon footprint. However, adopting sustainable HVAC solutions can reduce a data center’s environmental impact and energy consumption.

Lennox received a 2023 Green Builder Sustainable Product of the Year recognition.

Thermostats have come a long way since the first thermostat hit the market. So, it makes sense that consumers demand more from the technology’s capabilities than ever before.

The U.S. Department of Commerce is investigating whether Chinese HFCs are circumventing the 2016 antidumping duty order on HFC blends.

With more than a trillion dollars designated from the Infrastructure Investment and Jobs Act (IIJA) starting to hit the wider economic field, HVAC contractors and the utility industry should be aware of how to cash in.

Developments in zoning capabilites have brought mini splits into the multiroom realm. And it goes without mention that the march of engineering progress has taken ductless systems on the road, into parts of the country where no mini split has ever gone before.

Different areas have particular needs and also embrace new technology at different speeds.

While ductless HVAC is not without its flaws, the technology has evolved exponentially to now provide customers with numerous configurations at affordable prices appropriate for nearly every application, which is music to the ears of entrepreneurial contractors.

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.

Friedrich recently sponsored a NEWS webinar titled “Ductless Split System Innovations That Matter to Your Bottom Line.”  Below are questions taken from the Q&A portion of that webinar.

This product line features voice-activated control through the Google Assistant on smart speakers, if the mini split has built-in Wi-Fi.

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

The 25 SEER model is a wall mount unit with Wi-Fi capabilities, a silver ion filter, a cold catalyst filter, and a GoldFin anti-corrosive coating.

The two-story lake house totals 4,600 square feet above ground and 2,000 finished square feet in the daylight basement.

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.

Most of the rest of the world has relied on ductless mini-split systems for their heating and cooling needs for decades, but that has not been the case in the U.S. That may be changing with the advent of ducted mini-split systems.

In today's economy, cost-conscious end users want to extend their HVAC equipment lifespan as long as possible. Regular maintenance on condensing units can help maximize their longevity and performance.

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

In this month’s troubleshooting problem, the equipment is a split system that’s approximately 8 years old.

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

The first time a technician has to tackle a ductless mini-split can be nerve-racking, but by following these 10 tips, the job can be done without all the anxiety.

Panasonic Corp. of North America is honing in on its focus to make it easier for both residential and commercial building owners to control the temperature and comfort level within the space. The company hit its targets with the introduction of two new products — the ECONAVI air conditioner and the Variable Refrigerant Flow (VRF) Smart Connectivity Controller.

Honeywell announced the launch of Honeywell Forge Energy Optimization, a cloud-based, closed-loop, machine learning solution.

Aaon’s focus on serviceability and performance helped the WH Series earn gold in The NEWS’ 2017 Dealer Design Awards HVAC Light Commercial Equipment category.

David Heinemeier Hansson, creator of the Ruby on Rails framework and a partner at the software development company Basecamp, talks to Stefan Tilkov about the state of Ruby on Rails and its suitability for long-term development. He addresses some of its common criticisms, such as perceived usefulness for only simple problems, claimed lack of scalability, and increasing complexity. David also talks about the downsides of building JavaScript-centric, “sophisticated” web UIs, and why he prefers well-structured, “majestic” monoliths to microservices.
