HVAC in Port Ludlow, WA.
HVAC in Port Ludlow should include a clear handover for a thermostat that changes between heating and cooling. Ask how the supplied control separates its heating and cooling targets in Auto mode.
The household should be able to identify both targets and the intended mode. A setpoint-separation setting is a different question from deciding the equipment size or diagnosing a comfort fault.
Heating and cooling
Have the installer explain both Auto-mode temperature targets.
Ask the installer to demonstrate the heating target, cooling target and minimum permitted separation on the actual supplied control. Have the provider identify which settings are appropriate for the installed equipment and which should be left to qualified service. Keep a simple record of the intended household operation with the model-specific instructions. If the display will not accept a requested pair of targets, ask the provider to explain its configured limits rather than changing installer settings by trial and error. Assess continuing comfort complaints through the provider.
