HVACR service technicians find themselves at the forefront of the refrigerant transition in AC and commercial refrigeration. As hydrofluorocarbon (HFC) refrigerants with high-global warming potential (GWP) are being phased down, mildly flammable A2L refrigerants have been identified as potential lower-GWP alternatives. But information about A2L servicing requirements is largely unknown in the U.S., which raises many questions within the technician community. If you’re an HVACR technician, the chances of soon encountering A2Ls is very likely. It’s important to gain a better understanding of A2Ls to maximize safety and assist your customers with installation and service calls.
In comparison, a modulating furnace goes beyond a two-stage furnace and can have dozens of “on” settings. A modulating furnace begins at full speed, and once your house is sufficiently warm adjusts its settings in slight increments to change the amount of heat being put out. This method is more efficient and budget-friendly and ensures your home stays within one to two degrees of the desired temperature throughout the entirety of your day.
Due to the warm climate, homes in the Southwest need efficient cooling and dehumidifying systems as well as an option for light winter heating. While the majority of homes continue to use central cooling and heating systems, heat pumps are also widely used in the Southwest as an ideal solution for the mild winters.
Before you put your AC system away for the winter, you might want to consider having it checked out by a certified contractor. If it is older or has been giving you problems, you might want to have it replaced. AC replacements done in the fall often have much better outcomes for consumers than those done in the heat of the summer or when you first start your system up in the spring.
