Make a decision
Pre-winter booking versus emergency no-heat
One scope
Planned service allows inspection before sustained demand and time to compare a scope.
The other scope
A no-heat call prioritizes diagnosis and safe restoration, often under urgent timing.
A concrete example
A planned October inspection permits a documented comparison. A December no-heat call needs diagnosis first; its urgency and after-hours labour are separate from cleaning scope.
Which question settles it?
Do not delay urgent safety issues to preserve a low seasonal cleaning price.
