A Quick Guide to HVAC (Heating, Ventilation, and Air Conditioning)

What Does HVAC Stand For?

  • Heating 
  • Ventilation
  • Air 
  • Conditioning

HVAC is an abbreviation for heating, ventilation, and air conditioning. Heating and air conditioning refer to the temperature control of indoor spaces, and ventilation refers to the circulation of air through the home and indoor air quality. 

The HVAC industry has worked diligently to develop the efficient HVAC units found in modern homes. Heating, cooling, and ventilation are important parts of maintaining a healthy and comfortable home. In this blog post, HVAC experts share the basics that homeowners should know about heating, ventilation, and air conditioning units. 

How Does an HVAC System Work?

Homeowners should have a basic overview of how their HVAC system works. Most modern homes use a central air system, which distributes air to each room in the house through ductwork. HVAC systems include furnaces for heating and air conditioners for cooling the home. 

Modern home furnaces burn oil, gas, or propane to produce heat. Some heating systems use electricity or geothermal transfer to heat the home. Heat pump systems are extremely efficient for homes in moderate climates.

Ventilation is the part of the HVAC system that pushes the air throughout the home. The ventilation system includes components such as fans, vents, air filters, and ductwork. Ventilation is important for maintaining healthy indoor air quality and distributing air. 

Important Parts of the HVAC Systemcoil

  • Thermostat
  • Ductwork
  • Evaporator coil
  • Heat pump 
  • Furnace 
  • Air Filters

The thermostat controls the overall function of the HVAC system by turning on the heating or cooling to maintain the desired temperature. The furnace and air conditioner connect to ductwork that distributes the air through vents at the thermostat’s command. 

Most homes have both an indoor and outdoor component to their HVAC system. Air conditioners use evaporator coils containing refrigerant to cool the air, and then the heat and moisture are released via the outdoor unit. 

The ventilation of the HVAC system would not be complete without an air filter. An air filter is a mesh screen placed over the HVAC unit’s air intake to keep debris such as dust, dirt, and pet hair from getting sucked into the unit. Air filters are essential for protecting the indoor air quality inside the home. They should be replaced around every three months or more frequently, depending on the filter type or if allergy sufferers live in the house.

What Is HVAC Maintenance?

One of the best things homeowners can do for their HVAC systems is schedule routine HVAC maintenance with a qualified expert. Homeowners should always have a trusted local HVAC company a phone call away in case of an HVAC emergency. 

HVAC maintenance appointments include cleaning the air conditioning coils, changing the air filters, cleaning the inside of the unit, and checking for broken parts. During maintenance appointments, the technician will have a chance to fix small problems early before they get out of hand. 

Most HVAC maintenance should be left up to a qualified HVAC technician, but homeowners can change their air filters themselves. Changing an air filter at homet can take less than ten minutes. Changing the air filter on time can improve the performance and longevity of the HVAC system.

Learn About the Women Who Shaped the Heating and AC Industry

These Inspirational Women Changed Heating and Cooling with Their Contributions

Women in the HVAC industry stand out as trailblazers in the historically male-dominated profession. Despite there being fewer female HVAC technicians, women in the industry have been responsible for some of the most important inventions and advancements in technology. In this article, industry experts discuss the contributions of female inventors and engineers in the heating and cooling industry.

Women in the Cooling and Heating Industry Today

According to official labor statistics, women only make up a small percentage of the total workforce in the heating, air conditioning, and ventilation (HVAC) industry. The number of female HVAC technicians and contractors is as low as 1.4% of the workforce. Many more women work in management and support positions at HVAC companies as well.

A lot of the women in the modern HVAC industry are in senior leadership positions or own their own companies. Women in HVAC also work behind the scenes as engineers and inventors to create the latest heating and cooling technological advancements. Keep reading to learn about two of the most influential women in the HVAC industry.

Alice H Walker

Learn About Alice H. Walker, Inventor of the First Gas Furnace

Alice H. Walker is one of the trailblazing women in the heating and cooling industry that changed the world. Faced with chopping wood to warm her home during the freezing New Jersey winter, she set out to create a better solution.

She came up with the first gas furnace, which used a series of ductwork to distribute warm air throughout the house. Her design was unlike any that came before and was the basis for modern central heating systems. She patented her design in 1919.

Unfortunately, Alice H. Walker passed away a year following the patenting of her groundbreaking design. Her original patent had a few design flaws that made it a safety hazard. Still, by drawing off of her original concept, future inventors were able to create what we now consider the modern central heating unit found in most modern homes.

Learn About Margaret Ingels, First Female Mechanical Engineer

Margaret IngelsMargaret Ingels was a trailblazer for women in the heating and cooling industry. She is one of the most famous female engineers because she was the first ever to become a mechanical engineer. Margaret Ingels was only the second woman in America to get a degree in engineering, and she remains an inspiration to women in engineering today

She was driven from a young age to become an engineer. While most women in the 1950s were set out to become housewives, Margaret Ingels was determined to take her life in a different direction. After graduating with her engineering degree, she went to work for six years developing air conditioning units in a laboratory.

She worked alongside heating and air conditioning specialists to create a modern air conditioning unit. Margaret Ingels is an inspiration for women in engineering and other male-dominated career paths.
