With innovative smart technology, HVAC systems perform to match your house's unique needs during the day when your family is spread throughout the house. All smart HVAC systems are programmable by time of day and day of the week. Some units utilize sensors to measure a room's occupancy. In the evening, when your family has retired to the bedrooms, these units turn off the fans heating or cooling rooms such as the kitchen and living room. For parties or family gatherings, these smart HVAC systems recognize higher occupancy, and the fans adjust accordingly.

Some of the newer HVAC systems with smart technologies can sense frost on the coils of the outdoor units and are equipped to reduce the frost. This feature is especially convenient on cold nights and makes these units almost maintenance-free.

Another feature that some systems have is a sensor to measure humidity. When an increase of humidity is detected somewhere in the house, the appropriate fans turn on to remove excess moisture, reducing the impact on the temperature. Ventilation is also measured with these sensors, controlling fans throughout the house to maintain proper air flow and freshness in the home.

For added convenience, some new HVAC systems are controllable with your phone or online remotely. They also send notifications to you or technicians when appropriate, saving time for both the owners and technicians.
