What Is HVAC Technology & How Does It Work?

What Is HVAC Technology & How Does It Work_

HVAC systems are a fundamental part of modern-day living. HVAC maintenance is important to ensure that it continues working at its optimal condition. If you are looking to ensure that your HVAC maintenance plan keeps your system functioning, then you should contact us at Chapman Air & Heat, as we know HVAC technology like the back of our hands.

Let’s take a look at what exactly HVAC technology is so that you can have a better understanding of the kind of technology that has such a large impact on your quality of life.

What Is HVAC?

HVAC, which stands for heating, ventilation, and air-conditioning, is a technological development that traces back to the invention of the air conditioner in the early 1900s. The HVAC system is designed to control the indoor climate by maintaining a healthy humidity level and regulating temperature, while simultaneously purifying the air by processing it through a series of filters. 

Climate Control

The whole concept of HVAC is that it contains a heating component and a cooling component that work together to control the temperature of the air. The air is processed through a series of fans that distribute it throughout a network of ducts. Some HVAC systems can be quite large, with modern HVAC systems incorporating a range of smart controls and automated options, including automatic temperature and humidity control, air testing capabilities, and various other programmable actions.

HVAC systems incorporate a thermostat that regulates the temperature. These are generally highly programmable and can be adjusted manually as desired. Modern HVAC systems also include an array of sensors to detect things like humidity, temperature, and even air quality. These sensors help the modern system automatically adjust its settings to account for any changes in the air.

Heating And Cooling

The HVAC system consists of various different components that operate together to provide function. The first and most important of these is the actual heating and cooling equipment. 

We have come a long way since the days of simply lighting a fire in the fireplace to heat the building. Various furnaces, boilers, and other kinds of heating apparatus can be used to heat the air through either electronic means or by the consumption of fuel, such as gas.

In addition to the heating equipment, the HVAC system also houses a cooling unit. Such air conditioners generate cold air to assist in the regulation of the temperature. 

Air Cleansing

In addition to the heating and cooling equipment, which is central to the HVAC system’s functionality, the HVAC system also contains a range of air filters. Modern air filters are highly effective at eliminating pollutants from the air and improving indoor air quality. With a properly functioning HVAC system and clean filters, the incidence of dust, pollen, and mold spores is significantly reduced. 

Modern air purifiers have become extremely advanced, capable of eradicating numerous contaminants and allergens. The Reme Halo air purifier, in particular, is highly effective at sanitizing the air inside your home or business.


Modern HVAC systems typically use refrigerants to ensure that they are able to cool the air. These refrigerants are generally hydrofluorocarbons (HFCs), which are more environmentally friendly than chlorofluorocarbons (CFCs), which were used previously.

Air Distribution

The HVAC system would be incapable of having any impact on the air without a means of distribution, which is achieved through various ducts, vents, fans, and exhausts to distribute the air as needed throughout the building. All of these components require rigorous upkeep and maintenance.

Here at Chapman Air & Heat, we provide a comprehensive HVAC maintenance plan that will ensure that you receive your HVAC annual service. This will minimize the incidence of air conditioning repair that is required, saving you money in the long run. Keep your HVAC system working like it should by contacting us today.
