Though consumers are becoming more familiar with IAQ, it’s important for HVAC contractors to facilitate conversations that focus on indoor environmental problems and solutions and then let them make their own decisions.
On April 22, people all over the globe celebrated Earth Day. This holiday serves as a reminder to many that we all need to do our part to preserve the planet. While some plant trees, recycle, or clean parks, the HVACR industry touts the potency of geothermal heating and cooling.
As consumers become better educated about IAQ, the need for humidification and dehumidification — and the comfort solutions they provide — has increased. According to RnR Market Research, the global market for humidifiers is expected to surpass $1 billion by 2019. Another study, conducted by Grand View Research Inc., states the global dehumidifier market is expected to reach $3.54 billion by 2022.
Mold can be found everywhere, both indoors and outdoors. However, it’s usually not a problem until it begins growing indoors. According to the Centers for Disease Control and Prevention, exposure to mold can cause a number of health effects and symptoms, including allergic reactions, asthma, and other respiratory complaints. Mold can be a serious issue if left untreated, which is perhaps one of the reasons most HVAC contractors tend to avoid it.
While organizations that spend the most money will always gain favor in the marketplace, modern data analytics systems are now allowing suppliers to look at customers differently.
The Luxaire Acclimate Variable Capacity Residential Systems from Johnson Controls Inc. are high-efficiency residential systems with built-in advanced charge monitoring. This quick and accurate means of measuring refrigerant charge saves contractors time.
A few months ago, I wrote a Duct Dynasty article on the ideal duct system. The most frequent comments and questions I received about this article were regarding branch takeoffs. So, I thought it would be fun to take a deeper look at branch duct takeoffs and how to overcome some of the most common problems associated with them.
The Energy Star-rated EZ98-DV and EZ111-DV (Energy Factor: 0.97) are high-efficiency, condensing, tankless water heaters. The EZ98-DV has a maximum input of 180,000 Btuh and a maximum flow rate of 9.8 gallons per minute (gpm), making it generally suitable for homes with up to three baths.
The J-IIS variable refrigerant flow (VRF) technology is designed for smaller residential, multi-housing, and light commercial uses with equipment available in 3- and 4-ton sizes.
Every year, The NEWS introduces the latest cooling equipment available for the upcoming summer season in order to help contractors prepare for this busy period by doing the research that will help them to distinguish between brands.
The coverage features specific information about each individual product as submitted by the manufacturers.
Bob and Tim are at lunch after tuning up an oil burner. When they arrived at the job the home was cold and the oil burner was burning erratically if burning at all. They gave the system a tune-up, started the furnace, and decided to take a lunch break while the furnace heated the house. Then they were going back to do a combustion check on the furnace to make sure that it was set up for the best combustion.
At the 2017 AHR Expo in Las Vegas, several manufacturers showed off VR capabilities in their booths and explained how the technology is now being used for
Before I allow a tool into my work, I do a lot of online research. Then, I go for rigorous hands-on experience at trade shows, tool jamborees, or manufacturer
These high-efficiency systems feature inverter-driven variable capacity technology, which dynamically adjusts capacity and airflow, unlike systems that simply turn on or off. Air circulates more precisely and quietly, maximizing comfort while reducing energy consumption.
According to reports from AccuWeather, this summer is sure to leave Americans sizzling as most regions are expected to endure above-average temperatures.
Since the tax credits went into effect in 2008, many contractors have experienced a significant boost in their geothermal businesses. And, now that the geothermal tax credits have lapsed, contractors and manufacturers are prepared to continue forward without them.
Geothermal credits are being reintroduced in the form of the Reed Bill, legislation introduced by Tom Reed, R-N.Y., Mike Thompson, D-Calif., and 18 additional cosponsors (12 Republicans and six Democrats).
Ten years ago, the HVACR Industry Alliance was formed to act as the “unified voice of the North American heating, ventilation, air-conditioning, and refrigeration industry.”
Aire Serv Nation welcomed 175 members from the U.S. and Canada to the Hilton Nashville Downtown in February to celebrate a homecoming event that not only marked the franchise’s 25th anniversary, but also served as a springboard for the new Neighborly™ umbrella brand program for all Dwyer Group brands.
There is no doubt that we’ve come a long way from the 1990s, when there were very few people who knew the tax code and could fill out a paper IRS form properly. Now, technology is widely available, and many can create and file their own returns in a matter of hours and avoid any issues going down the road.
Demand for air source heat pumps is forecast to increase 2.5 percent per year through 2021 to $2.1 billion. Air source heat pumps comprise a significant amount of total heat pump demand, largely due to the easier installation requirements and lower initial costs than geothermal heat pumps. Air source heat pumps also compete more directly with other HVAC equipment and are a viable heating and cooling option in most buildings.
Recently, the Trump administration announced plans to defund Energy Star. The administration claims it is not a priority for taxpayer dollars and actually lumps it into the category of ‘lower priority and poorly performing programs.’ But, 25 years of Energy Star experience tells a much different tale.
Compressor burnout is a very specific mode of failure that may be caused by high temperatures in the motor windings or discharge area of the compressor.
While many educational sessions were presented at the Air-Conditioning, Heating, and Refrigeration (AHR) Expo, perhaps the most popular was the course on global HVAC trends offered by the Building Services Research and Information Association (BSRIA).
BACnet Intl. recently developed The BACnet Institute, an online center for BACnet educational resources that provides an easy path to BACnet information and learning for everyone involved with BACnet systems as well as forums to share knowledge.
Residential and commercial sectors, coupled with rising disposable income, are augmenting demand for air conditioners across the globe. Growing acceptance of air conditioners as a utility product, rather than a luxury product, is anticipated to boost growth in the global air conditioners market during the forecast period.
In 2017, the winds of change are blowing stronger than ever with a new commander in chief calling the shots. Most industry experts are hopeful and optimistic about the next four years under a Trump-led government.
According to Chisult Insight Co. Ltd.’s Global and U.S. HVAC Market Research Report, the U.S. HVAC market is estimated to achieve 5 percent growth in 2017.
