What Does HVAC Stand For and What Is It?

An HVAC system, which stands for heating, ventilation, and air conditioning, is a system that is used to control the temperature, humidity, and air quality in a building or space. It is designed to provide comfort and maintain a healthy indoor environment. They can be found in residential and commercial buildings and industrial facilities. An HVAC system consists of various components, including a furnace or heat pump, air conditioner, air ducts, and thermostat, all working together to regulate the temperature and airflow. Understanding the basics of HVAC systems is essential for anyone looking to maintain or upgrade their system, as well as for professionals in the industry.


How Does an HVAC System Work?

HVAC systems work by controlling the temperature, humidity, and air quality in a space. It typically consists of three main components: a heating unit, a cooling unit, and a ventilation system.

During the colder months, the heating system (such as a furnace or heat pump) will create warm air and distributes it throughout the space. The warm air is drawn in through return vents, passes through the heating unit where it is heated, and then is distributed through supply vents.

During the hotter months, the cooling unit (such as air conditioning systems or heat pumps) will create cool air and removes excess humidity. The air is drawn in through return vents, passes through the cooling system where it is cooled and dehumidified, and then is distributed through supply vents. Who doesn't value their cool air when the temperatures rise? If you need even more cooled air, you can consider adding in window air conditioning units to your home.

The ventilation system is responsible for bringing fresh air into the space and removing stale air. It helps maintain and improve indoor air quality by removing pollutants, odors, and excess moisture. The ventilation system can include features such as an air filter, air purifiers, and exhaust fans.

The HVAC system contained a temperature control unit called a thermostat, which allows the user to set the desired temperature and control the operation of the complete system. Some advanced HVAC systems also have smart features that can be controlled remotely through a smartphone or other devices.

Overall, a complete HVAC system works by providing a comfortable and healthy indoor environment by regulating temperature and humidity, while also working to improve air quality. Regular maintenance and proper usage are important to ensure the system operates efficiently and effectively, as well as using the proper amount of energy consumption. It is vital to make sure that your system has proper ventilation and is providing acceptable indoor air quality.

HVAC Care and Maintenance



Maintaining regular service for your heating ventilation and air conditioning system is crucial to ensuring that everything works correctly and that the likelihood of losing service in the middle of one of the hottest heat waves or one of the coldest winter days is reduced. It is also important to ensure that you are provided with fresh hair and consistent indoor air quality. At JF Denney we strive to make this a simple process, one where you do not have to worry about doing any of the work.



JF Denney offers a monthly maintenance plan for all of our HVAC systems. With our preferred customer agreement plan, you will receive two yearly check-ups on your HVAC system - one in the Spring and one in the Fall. What exactly do these check-ups consist of? On the day of your appointment, one of our skilled technicians in the HVAC industry will do the following:


  • Clean the burner assembly to improve combustion, which in turn will reduce wasted heat (saving you money!).


  • Tune the furnace burners for more efficient burns, promoting energy efficiency.


  • Clean the ignition assembly to ensure safe operation on demand.


  • Inspect the furnace heat exchanger to ensure safe operation and the absence of cracks from metal fatigue.


  • Verify the flue draft to ensure that dangerous gas by-products are properly venting to the outdoors, leading to better indoor air quality, and flue pipes are free from obstruction.


  • Inspect the flue draft to ensure no corrosion is present which can lead to cracks and the introduction of dangerous fumes into your home.


  • Check for carbon monoxide to ensure that none is present and your home and family are safe.
