Working as an HVAC technician is a demanding job that requires specialized training. Typical tasks include lifting heavy equipment and working in tight spaces. Technicians may also need to climb ladders and perform installation work on rooftops. This job also requires the ability to diagnose and adjust system components. A degree in HVAC technology will be beneficial for a career in this field.

HVAC systems are integrated systems that combine ventilation, heating and cooling functions. These systems are controlled by a thermostat, which can be conventional or smart. Some models can alert homeowners of a problem or share diagnostics with an HVAC contractor. HVACs are required in all types of buildings, whether residential, commercial, or industrial.

A duct system is an important component of an HVAC system. It routes air in and out of a building to different areas based on the requirements of the building. It can also remove dust or reduce humidity. A central air system moves air through a network of ducts. If the ducts are blocked by plants, they may cause an HVAC problem.

HVAC systems can be installed as standalone units or as part of a larger network. This allows for economies of scale and can utilize renewable energy sources. Some systems utilize solar heat, lake and seawater, seasonal thermal energy storage, and other natural resources to heat or cool a home or business.
