Notable Women in HVAC History

When we talk about the great technological achievements throughout history, we tend to focus on the accomplishments of men. However, in any field, there are always plenty of women whose contributions are just as important, but often go unsung. The field of HVAC is no exception. Here are two women in HVAC history who helped define home comfort as we know it.

Alice H. Parker

For years, homes were heated primarily using wood or coal burning furnaces. Heat would eminate from the unit, which would then spread to the rest of the house. Then in 1919, African American inventor Alice H. Parker changed all that, by inventing a new, safer furnace that burned natural gas instead.

Furthermore, the furnace would heat up the air and distribute it throughout the house via a system of ducts and vents. This way, heat could spread through a home more evenly. Her furnace even allowed homeowners to set different temperatures for different areas of the house according to their individual needs - a concept that wouldn't become widespread until decades later, with the introduction of zoning systems.

Margaret Ingels

Another of the important women in HVAC history was Margaret Ingels. One of the first female engineers in America, she was the first woman to receive a professional Mechanical Engineering degree.

Spending six years in the American Society of Heating and Ventilating Engineers research lab beginning in 1920, Ingels researched how to measure the amount of dust and contaminants in the air in public places. Her crowning achievement, though, was the sling psychrometer, which measures the amount of moisture in the air.

In so doing, Ingels was able to develop the "effective temperature" scale. This scale considers factors like relative humidity and air movement in order to determine the "feels like" temperature when it comes to home comfort.

These are just a few of the women who helped define home comfort as we know it today. To learn about other women in HVAC history, contact us at Air Assurance. We've provided Broken Arrow with quality home comfort solutions since 1985.

The Biggest Changes in HVAC History in the Last 5 Years

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.

Smart Technology

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.

Efficiency Standards

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.

Refrigerant Phase-Out

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.

Sensor-Driven Equipment

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.
