Every year, as the temperature pushes toward 100°F, I’ve proposed a ductless mini-split system to my father-in-law for his vacation home on Lake Michigan. Each year, his rebuttal remains logical: “We’re not there enough to justify the investment.” Until this year, his stance changed.
When considering the multitude of HVAC thermostat options available on the market, who better to decipher the best from the rest than those responsible for their installation and operation?
In the 12 months since the $41 billion law was signed into law, the U.S. Environmental Protection Agency (EPA) has leveraged the legislation as an engine to reduce emissions, build a cleaner economy, lower energy costs for American households, and advance environmental justice across the country.
Suddenly in high demand, HVAC contractors must quickly acclimate themselves with CO₂ refrigeration and its unique characteristics and service attributes, which differ from traditional hydrofluorocarbon (HFC)-based systems.
Water-source VRF/VRV units are often specified for large building and high rises applications as both contain water-cooled modules that are located indoors, closer to the space they’re serving.
CO2 is a highly attractive refrigerant for contractors and end users because it boasts a global warming potential (GWP) of 1 and an ozone depletion potential (ODP) of zero.
Numerous obstacles, including mild weather, a lack of demand, a shallow pool of skilled tradespeople, increased competition, inflation, supply chain shortages, and more, have stood in the way of contracting success throughout cooling season.
Building vertifications serve as environmental and sustainability badges of honor, demonstrating excellence not only for the facilities but the contractors twisting the wrenches as well.
