About This Service
Keep an earlier report available
An earlier report gives the assessment useful context, particularly when you were advised to repair a particular component. Share the complete relevant finding if available. Twin reviews the current condition and recommendation, rather than assuming an old photograph still represents the installed system.
Make inaccessible areas explicit
Some areas cannot be assessed through ordinary available access. That limitation should remain visible in the explanation of findings. Twin discusses whether another step is needed to resolve the question, rather than treating an unseen component as confirmed sound or confirmed damaged.
Understand a Damper Observation
A handle that moves does not by itself describe the position or condition of every connected part. Tell us what seems different and avoid forcing the mechanism. The assessment identifies the relevant components before a damper adjustment, repair or replacement is proposed as the next step.
Identify a Reported Termination Obstruction
A concern at the outside termination should be described without trying to remove the material or climb to it. The assessment needs to identify both the obstruction and the installed system. Ordinary cleaning, component repair and an active animal concern may need different next steps.
