If you haven't updated your HVAC system in a number of years, you may not be aware of big changes that have taken place in the HVAC industry. Here are some things you might want to know about recent HVAC history that can have an impact on your next HVAC system purchase.
Of course smart technology has been coming on for a while, but in the last five years, it's moved front and center in the operation and control of HVAC systems. With the introduction of smart thermostats such as the Nest and others, more and more consumers are controlling their systems from near or far with a smart device.
In 2015, the Department of Energy adopted new energy efficiency standards for heat pumps, air conditioners and furnaces. These standards have motivated the HVAC industry to work harder on technological innovations for achieving ever greater efficiency.
The widely used refrigerant R-22, which has been proven to be harmful to the ozone layer, began to be phased a few years ago. While older systems still use R-22, as of Jan. 1, 2020, the refrigerant will no longer be manufactured and cannot be imported into this country. That means owners of equipment using R-22 will have to pay big prices for dwindling stocks of the refrigerant when their equipment develops a leak, as you cannot use the new refrigerants in air conditioners that require R-22.
So many systems are now being designed to be activated by sensors that we can't list them all, but here's one that was introduced in 2015 and can provide precise room-by-room temperature control: the Ecovent. Controlled by a smartphone app, the sensor-driven vents replace existing wall, ceiling or floor vents.
Non-Vapor Compression Technology
In 2015, the U.S. Department of Energy began funding research for non-vapor compression technologies, which won't require coolants to chill air. This could reduce energy use for cooling equipment by as much as 50 percent.
