Modern-day architectural norms require buildings to be fitted with high-end technology systems, whether in their foundation or as part of the lighting and electrical systems. The inclination is towards automated and cost-effective systems that offer comfort, convenience and a healthy environment.

Lately, apart from other domestic automation systems, the Heating, Ventilation and Air-Conditioning (HVAC) systems are also gaining popularity.

HVAC systems involve a furnace, conditioner and ductwork and their primary purpose is to maintain high air quality in a building. These systems perform through their digital control systems and electronically commutated motors that allow heating, cooling and recirculating of air.

Apart from being cost-efficient, HVAC systems are also known for:

• Controlling temperature
• Maintaining fresh air circulation
• Filtering air

While this technology was more common in commercial buildings earlier, it is now common in residential buildings, too. In a residential setting, the heating system is fitted to deliver warm air during the winter and cool and fresh air during the summer months. When the thermostat senses that the air inside the house is too cold, it sends signals to the furnace to deliver warm air. The mechanism is the opposite during the summer.

One can control the temperature of the entire house or a specific room, depending on the type of HVAC system installed. In some systems, automatic sensors detect whether there are people in the room, and accordingly warm or cool the space. Linking the HVAC system with the home automation system also allows one to use their smartphone to turn off the air-conditioner, even when away from home.

The upfront cost of HVAC systems may be relatively higher than normal air-conditioning systems. But, the resulting long-term financial benefits compensate the instalment expense.
