This product has a new modular construction scheme with the thermal performance of the company’s patented nuCore Heat Exchanger.

Designed to maximize reliability and uptime, this product allows technicians to stay dry while safely inspecting the basin with an internal walkway.

Demand is changing the landscape of coils and condensers. Efficiency, refrigerant, and market demands are adjusting to a global cooling marketplace.

The higher the inlet water temperature, the more sensible heat must be removed from the water and the longer the freeze cycle. The latent heat removed causes the water to change state, thus producing ice.

If an ice machine evaporator has a grid design, it can separate from the evaporator plate over time, causing ice to form between the two parts, causing problems.

Ducts play a crucial role but are often overlooked.

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

Don’t assume equipment capacity or conditions. Instead, do some digging and find the tables for the equipment you install and service.

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.

These new programs and reactivations include occupations such as machinist, HVACR technician, electrician, plumber, cement mason, ironworker, operating engineer, and a new occupation in certified cyber analyst operator.

Seven of the awards include funding specifically for HVAC-related projects.

67% of contractors see digital transformation as important to their success.

With modern technology, HVAC contractors can leave paperwork behind, and instead share information in real-time.

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.

Azuga studied 3.6 million driver behavior datasets from its GPS fleet tracking devices over the first five months of 2019.

Having the right fleet management solution can increase employee accountability, efficiency, safety, and grow an HVAC company.

Used in new construction and retrofit applications, the product is small, light, and customizable.

Daikin Applied introduced two chillers and a rooftop unit and also took the opportunity to discuss the company’s decision to transition to R-32.

The 48,000-square-foot facility aims to streamline Endress+Hauser's global product distribution.

EPA recently expanded its list of acceptable refrigerant substitutes for new refrigeration equipment to include R-471A and R-515B.

Renters who can’t turn on the a/c want to change mandates that don’t require cooling until May 15.

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

Evaporative cooling is growing in demand as cooling needs are expanding.

Renewable energy enthusiasts now have reason to celebrate: EVAPCO offers a solar-powered evaporative cooling tower. The SUN cooling tower is paired with PV panels to dramatically reduce energy consumption.  

Although evaporative cooling is great at saving energy, it does consume some water, but the benefits on energy savings outweigh the water usage, which in some places is a scarce resource.

In the past few years, the thermostat has become a cutting edge electronic. This creates new opportunities for HVAC contractors.

Thermostats are like other pieces of interactive equipment: People are thrilled by each development but move on quickly when the next feature comes along.

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.

While traditional hospital HVAC systems often consist of chillers and boilers, other types of equipment are becoming more widely accepted in the health care market, including variable refrigerant flow (VRF) systems, air curtains, and geothermal heat pumps. 

Food retailers shared their concerns and experiences with refrigeration systems that use alternative refrigerants at the Food Marketing Institute’s (FMI’s) 2023 Energy & Store Development Conference.

AHRI launched an interactive US map showing state codes for A2L refrigerants, alongside a video series on low-GWP refrigerant transition.

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.

The proposed new approach to chilled water HVAC systems promises to provide significant capital cost savings, energy cost savings, and a path to eliminate CO₂ emissions.

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 buildings of tomorrow are chock full of Internet of Things (IoT) devices and equipment that connect tenants, mechanical systems, and facility managers to up-to-the-minute data and progress reports.

This product is integrated to help users work toward earning LEED requirements and other sustainability and accreditation and education agendas.

Aircuity has been named a New York State Energy Research and Development Authority Qualified Vendor for the RTEM program.

On Dec. 17, 2015, the U.S. Department of Energy (DOE) finalized new negotiated energy conservation standards for commercial air conditioners, heat pumps, and commercial warm-air furnaces, otherwise known as rooftop units (RTUs).

Daikin Applied’s recently introduced SiteLine Building Controls gives building owners and operators the tools and insights needed to optimize performance, improve IAQ, and trim energy use and carbon emissions.

HiberSense Inc. appointed Chris Lawson as channel sales manager for the U.S. market.
