Abstract
A system and method of monitoring the performance of an HVAC system including a controller in communication with an HVAC unit where the method includes monitoring environmental conditions using a controller. A target rate of change in indoor air temperature (IATR) can be established, and one or more adjusted environmental values can be adjusted to account for the adjusted IATR measurement. An adjusted IATR value can be established using one or more equations adjusting for a target sensible capacity value of one or more environmental factors in comparison to the measured sensible capacity of the one or more environmental factors to determine the adjusted IATR. The environmental factors can include but are not limited to the indoor air temperature, indoor humidity, outdoor air temperature, and any other measured parameter that could affect system capacity. The system can generate an alert when the adjusted IATR value reaches a pre-determined threshold.
