Often we are asked how many vents are needed to be replaced for Hibersense to operate effectively and our answer is always the same. “You should put sensors in every room and replace all (or most) vents.”
Of course, this is the easy answer, but it is also the correct answer as it allows Hibersense maximum information and control of airflow (the key driver of comfort in individual rooms). In our experience, you just cannot replace a few vents and expect to have sufficient airflow control. If you could, you would be able to open and close one or two vents manually and be happy but you know this does not work because you have tried that!
Many times, people try to figure out how they can use Hibersense products in a way that makes sense to them, but not following our recommendations. The problem with this approach is that most of us don’t know how to engineer an HVAC duct system nor how to fix a system that is already installed. This is where the power of Hibersense can come into play, but only if you let it.
Hibersense analyzes the data from all room sensors and all vent sensors while monitoring your preferred settings and room occupancy. Hibersense then intelligently conditions rooms as needed unlike conventional “smart” thermostats that still indiscriminately blow air around the entire house. Further, Hibersense can make additional recommendations for system operations based on temperature of conditioned air at each vent. It should be well noted that individual vent discharge air temperature is NOT the same in every vent. This further adds to the challenge of comfort control which NO thermostat can monitor let alone control.
These are just some of the reasons why we recommend what we do. There are many, many more factors that impact your HVAC system’s ability to properly heat and cool your home. Thankfully, we no longer need to accept these limitations and we now have the power to take control, but only if we do so properly.
