Heating, ventilation, and air conditioning (HVAC) systems are often referred to as climate control. They regulate temperature, air quality, and humidity. Heating and cooling systems were first used in commercial buildings but are now routinely installed in residential homes.
The HVAC system consists of two main parts – an external condenser and an internal evaporator coil. These two components work together to circulate cooling, drying, or warm air through the HVAC ducts in your home. The heating, ventilation, and air conditioning offsite build system is designed to achieve the environmental requirements of the comfort of occupants.

Depending on your specific needs, it may be possible to get both components in one external device. Consult your HVAC installation company to determine if this is an option for you.

Compared to traditional heating and cooling methods, HVAC systems are easier to adjust and more efficient. They can be installed with a "zone" control, which allows you to precisely regulate the climate in a particular area or room. Central air systems are initially more expensive than traditional heating and cooling methods, but the costs can be recouped in the long run due to energy efficiency, flexibility, and the ability to upgrade heating systems.

Keep in mind that lowering the thermostat even one degree can have a dramatic impact on your energy bill. You can choose to install a thermostat that allows you to precisely control the climate in your home on a schedule or a thermostat that controls a specific room.

Remember to change the air filter regularly, usually once a month. Keep the external components of the air conditioner away from dust and dirt to prolong its service life.
