Looking Back at the Last Decade of HVAC

Looking Back at the Last Decade of HVAC

The HVAC industry is tremendously different from what it looked like several decades ago. We’ve seen a number of technological changes in the past few years that have aimed to increase energy efficiency and customer utility. Let’s take a quick look into recent HVAC history.

R-22 Phase-Out

The R-22 refrigerant contains ozone-depleting chemicals. As a result, it was phased out by the Environmental Protection Agency (EPA). In January 2010, the production, importation, and use of the refrigerant were banned, with the exception of continued servicing of the needs of existing HVAC equipment. On January 1, 2020, a ban on the remaining production and import of the refrigerant came into effect. The servicing of R-22 equipment will now have to use reclaimed quantities of the coolant.

Smart Technology

In 2011, Nest launched its smart thermostat, which allowed users to connect their HVAC systems to the internet. Other startups followed suit. By 2015, the smart thermostat market had grown by 123%.

In 2016, smart vent systems started gaining traction, with several systems hitting the market. These ventilation systems have sensors that allow you to monitor and customize the airflow in the rooms of your house.

Variable Speed Technology

In 2011, Emerson released its variable speed compressor, which would significantly reduce energy consumption by HVAC systems. It became critical to other HVAC advancements in the next few years.

According to research released in December 2013, variable speed, magnetic-levitation chiller compressors were found to improve A/C efficiency significantly. Research also revealed that variable flow refrigerant (VRF) technology could result in greater temperature control and energy savings. A VRF system can heat and cool different spaces in your home simultaneously, allowing you to create different temperature zones.

From recent HVAC history, it’s clear to see that the next generation of HVAC systems will be significantly more energy-efficient and environmentally friendly.
