HVAC, or heating and ventilation systems, are a necessary part of homes and commercial buildings. These systems use a series of electrical components to regulate temperature and humidity. They can also be found in vehicles, medical facilities, and marine environments. While these units work independently, they are most commonly combined to create a more efficient environment.
HVAC is a complex system that combines design, installation, controls, and cooling functions. A contractor will determine the required capacity of a building before designing and constructing an HVAC system. They will also choose the proper refrigerant and components. HVAC systems are also designed and analyzed by mechanical and building service designers. Specialty mechanical suppliers and contractors will fabricate and install these systems. These systems normally require building permits and code compliance inspections.
A thermostat is another essential part of HVAC systems. This device allows the homeowner to control the temperature in their home. However, the thermostat must be compatible with the HVAC system that is in place. Many manufacturers now make thermostats that work with different HVAC systems. Some thermostats are digital, while others are analog. Choosing the thermostat that best fits your needs is an important part of maintaining a comfortable home or office.
Proper maintenance is essential in order to keep the HVAC system in working order. Properly maintained HVAC systems will save energy while minimizing exposure to pollutants.
