Ever wondered how a building automatically cools itself during the summer and warms up during the winter? Well, HVAC systems are responsible for keeping rooms, facilities, or spaces at the appropriate temperature.
Not to worry or get confused about the name though, simply put, HVAC is short for Heating, Ventilation, and Air Conditioning systems, and fortunately, this article simplifies everything you need to know about it and how it works. By the way, get here for heat repair Ashland City.
How do HVACs work?
Fresh air is necessary for human survival, and HVAC systems help to make it happen. When the weather is hot and stuffy, the Air Conditioning part of the HVAC system kicks in, cooling the air around you. Likewise, the heating system heats the room when the air is too cold – especially in the winter.
Although most buildings and houses have natural ventilation and aeration systems, the HVAC system functions as a mechanical ventilation system.
Uses of HVAC
HVACs are used in industries where human comfort is mandatory; industries such as pharmaceuticals, FMCGs, laboratories, hospitals, and other manufacturing industries.
Another industry that uses HVAC systems is the frozen food and icing industry. Do you know how your frozen foods are kept fresh and iced at the supermarket? Well, the HVAC system makes that happen.
HVAC systems are also used in the energy industry, as they are cost-efficient and energy-saving. HVACs provide the saves the environment through their minimal carbon usage and environment-friendly proponents, which is beneficial to the ozone layer.
HVAC system components
The HVAC system comprises some components that condition the air to maintain comfortable temperatures, suitable to spaces and people who occupy those spaces. These components include;
Air Filter
This component is a part of the HVAC system that takes out unwanted dust and particles, filtering the air quality circulated into the building or space.

Evaporator coil
This component cools the air when the thermostat is lower, especially during warm weather conditions.
Condensing unit
This is a component of the HVAC system that is connected to the evaporator coil. It is usually installed outside the house and is filled with refrigerant gas that helps it function properly.
Ducts
The duct system helps distribute air around the building and is kept clean for maximum performance.
Vents
These outlets transmit the heated or cooled air from the duct system into the house or office space.
Types of HVAC systems
HVAC systems are available in different sizes but come in four major types; Split HVAC systems, Hybrid Heat Split HVAC systems, Duct-free (ductless) HVAC systems, and Packaged heating and air HVAC systems.
Factors that affect pricing and cost of HVAC systems
Location
Depending on your geographical location and other related factors like climate change, the cost of finding a suitable HVAC system for your home or office space may differ. For moderately cool regions, heating systems may be more expensive, while getting in a more hot zone may be cheaper.
Size and construction
The more extensive the home or office space, the more energy is required to heat or cool it up. This, of course, would cost more when it comes down to finding an energy-saving HVAC system that works.
Ductwork
When a duct system is properly designed and installed, it ensures maximum comfort and minimal energy usage, and this feature does not come cheap. It would cost more to get an HVAC system that functions with a working duct system than one that doesn’t.
