Abstract
Methods and related systems for diagnosing a loss of capacity of a heating, ventilation, and air conditioning (HVAC) system are disclosed. In an embodiment, the method includes summing a runtime of an auxiliary heat source of the HVAC system over a plurality of time blocks. Additionally, the method includes summing an expected runtime of the auxiliary heat source over the plurality of time blocks. Further, the method includes comparing the runtime sum with the expected runtime sum, wherein the expected runtime for each of the plurality of time blocks is a function of an outdoor ambient temperature over a time-delay block beginning before the corresponding time block.
