1. A system for detecting behavior of HVAC control systems comprising:
- a first HVAC control system that receives inside temperature measurements from at least a structure conditioned by at least one HVAC system, and receives status of said HVAC system;
at least a second HVAC control system that obtains inside temperature measurements from at least a structure conditioned by a second HVAC system, and status of said second HVAC system;
one or more databases that store at least said temperature measurements and said at least a second climatic condition related to said first structure over time, andone or more processors that receive and records measurements of outside temperatures and at least a second variable outdoor climatic condition from at least one source other than said first and second HVAC systems and receives, records and compares said temperature measurements from said first HVAC system and said second HVAC system and said outside temperature measurements and at least a second variable climatic condition over time to determine the efficiency of the first HVAC system and the second HVAC system.

Abstract
The invention comprises systems and methods for evaluating changes in the operational efficiency of an HVAC system over time. The climate control system obtains temperature measurements from at least a first location conditioned by the climate system, and status of said HVAC system. One or more processors receives measurements of outside temperatures from at least one source other than said HVAC system and compares said temperature measurements from said first location with expected temperature measurements. The expected temperature measurements are based at least in part upon past temperature measurements.
