Abstract: A controller is configured to operate a heating, ventilation, and air conditioning (HVAC) system based on a first plurality of particulate matter measurements and a second plurality of particulate matter measurements. The controller is configured to determine an air filter efficiency for an air filter based on the received first plurality of particulate matter measurements and the received second plurality of particulate matter measurements. The controller is further configured to determine if a quantity of particulate matter in an airflow exceeds a first threshold value based on the received second plurality of particulate matter measurements. In response to determining that the quantity of particulate matter in the airflow does exceed the first threshold value, the controller is configured to transmit a notification indicating an action to inspect the air filter.

Abstract: A controller is configured to operate a heating, ventilation, and air conditioning (HVAC) system based on a plurality of concentration measurements received from a gas sensor, wherein the gas sensor is disposed within a sensor housing upstream of an evaporator coil. The controller is configured to receive the plurality of concentration measurements and determine if a concentration of total volatile organic compounds (TVOCs) in an airflow exceeds a first threshold value. The controller is further configured to operate the HVAC system in a second mode of operation to increase ventilation in response to determining that the concentration of TVOCs in the airflow does exceed the first threshold value, wherein a volume of air is introduced into and discharged from the HVAC system during the second mode of operation.
