The most important features of electronic measuring devices have been established in customer surveys and are discussed in this article.

Technicians have the choice of using either a digital or mechanical manifold gauge. Each one has its benefits and disadvantages, which is why it may pay to own one of each kind.

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

OK, you’ve exhausted all of the existing air from an interior space; now how do you replace it? You bring in makeup air from another source. For the purpose of an HVAC discussion, your source will be mechanical equipment — makeup air units.

Heat-only, direct-fired, and indirect-fired makeup air units have been added to the company’s product line. 

The Magnitude^® magnetic bearing centrifugal chillers from Daikin Applied not only reduce maintenance requirements and offer increased efficiencies, according to one Dealer Design Awards judge, but they also feature nearly nonexistent compressor vibration and top-tier customer support. 

The unit includes a standard neoprene, vibration-isolated blower and motor for quiet operation.

Ideal for cost-conscious applications that require 100 percent outside air, the new unit from Modine provides first-rate efficiency with a 100 percent thermal efficiency (92 percent sensible), and extends airflow capability to as low as 800CFM to cover far more applications than previously offered.

The MUAA distributes tempered fresh air to provide maximum comfort to the occupants in well-ventilated homes. The heating elements modulate continuously, which allow fresh, hot air at a low cost.

Not only has VRF technology been widely accepted by contractors and end users alike, virtually every major U.S. manufacturer is now offering these systems, as well.

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.

Our Lady of Guadalupe Catholic Church’s community center in the Tempe, Arizona suburb of Guadalupe now has state-of-the-art HVAC thanks to variable refrigerant flow equipment, accessories, and installation labor donations from RectorSeal, Panasonic Air Conditioning Group (a division of Panasonic Corp. of North America), and Woody’s Heating and Air Conditioning.

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.

With over 1,000 Sunday service attendees and many church activities throughout the week, energy efficiency for the sake of cost savings was critical.

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

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.

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

Cleaning coils is a fairly simple task, but one that plays an important role in keeping a unit running strong.

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.

Over time, dirt, dust, pet dander, debris, and more accumulate in air ducts. And since the HVAC system works basically as a whole-home vacuum, all of that is recirculated through homes when the HVAC system runs, unless the ducts are cleaned out.

Soap bubbles have long been thought of as the standard method for leak detection, but times, and technology, are changing.

Cleaning evaporator coils in a walk-in cooler can be challenging, but it needs to be done in order to keep the system operating efficiently.  

The moment for geothermal seemed to have arrived several times since the 1970s. A number of factors are forecasting wider use of this type of heating and cooling solution.

Decarbonization and electrification, the refrigerant transition, and incentives were big topics among geothermal companies at the AHR Expo. Consumer education and ease of product serviceability were also discussed.

The bill significantly reduces the cost of a geothermal installation, spurs job creation, and hopes to inspire more contractors to tap into the geothermal market.
