CFCs were once considered a triumph of modern chemistry. Stable and versatile, these chemicals were used in hundreds of products, from military systems to the ubiquitous can of hairspray.

Pinewood Forest is one of several large, master-planned developments that’s sidestepping the traditional HVAC system to embrace — and mandate — geothermal heat pumps for heating and cooling communitywide.

Midwest Machinery has sold and started up a ton of boilers to date. In the last 10 years, high-efficiency, high turn-down boilers have become the gold standard. Just like a Ferrari, which needs the right fuel, brakes, tires, and equipment precisely tuned to run like a champ - so does your new boiler. 

Researchers at the U.S. Department of Energy’s Ames Laboratory have designed and built an advanced model system that successfully uses very small quantities of magnetocaloric materials to achieve refrigeration-level cooling.

The California Air Resources Board (CARB) recently adopted a regulation that would prohibit the use of HFC refrigerants, claiming that the chemicals trap heat in the atmosphere at a rate thousands of times that of carbon dioxide.

The U.S. Environmental Protection Agency (EPA) recently issued guidance stating that it plans to abide by the recent court decision that ruled EPA is not authorized to ban HFC refrigerants under the Clean Air Act.

With almost 30 states now allowing some sort of legal use of marijuana, it is not surprising that the number of cannabis growing facilities in the U.S. is exploding. These growing facilities range from small farms that supply medical marijuana to local patients to large, multimillion-dollar facilities that produce enough to supply entire states with both recreational and medical marijuana.

Cultivating cannabis commercially is a difficult task. Growers can’t simply toss a few seeds into the soil and expect plants to produce the luscious buds desired by medicinal and recreational users across the nation.

The legality of marijuana use, both medically and recreationally, continues to increase across the U.S. Ballot initiatives are popping up in new states seemingly every year, which means the marketplace is burgeoning and spreading around the country. As it pertains to the HVAC industry, this can be a bit of a double-edged sword.
