1. A system for evaluating changes in the operational efficiency of an HVAC system over time comprising:
- at least one HVAC control system associated with a first structure that receives temperature measurements from at least a first structure conditioned by at least one HVAC system, and receives status of said HVAC system;
one or more processors that receive measurements of outside temperatures from at least one source other than said HVAC system and compare said temperature measurements from said first structure over time; and
one or more databases that store at least said temperature measurements obtained from said first structure over time,wherein said one or more processors compares an inside temperature recorded inside the first structure with an inside temperature of said first structure recorded at a different time to determine whether the operational efficiency of the HVAC system has decreased over time.

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.

8. A system for detecting behavior of HVAC control systems comprising:
-
a first HVAC control system that receives 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 temperature measurements from at least a structure conditioned by a second HVAC system, and status of said second HVAC system; one or more processors that receive measurements of outside temperatures from at least one source other than said first and second HVAC systems and compare said temperature measurements from said first HVAC system and said second HVAC system and said outside temperature measurements over time to determine the efficiency of the first HVAC system and the second HVAC system; and one or more databases that store said temperature measurements from said first and second HVAC systems. - View Dependent Claims (9, 10, 11, 12, 13, 14)
