Circuit Breakers and Disconnect Switches
Make sure all breakers and switches are fully in the “ON” position. It is best to turn them off and then on again to be certain they are actually on.
Make sure the utility company has not interrupted electrical or gas service for any reason.
Check for clean filters. Excessively dirty filters restrict airflow and can damage your equipment. We recommend that the filters be changed at least twice a year.
Registers and Grilles
Make sure that your supply registers are open in the area that is not cooling or heating properly. (In no event should the registers be set so that more than 25% of the total system airflow is cut off.) Care should be taken to ensure that furniture or other items do not block the airflow to or from the registers and grilles.
The thermostat must be set in the proper mode (either heating or cooling) and the setting must be below the indoor temperature for cooling or above the indoor temperature for heating in order for the system to operate.
