Use this guide to prepare for a conversation with a qualified chimney professional. The right scope depends on the appliance, venting system, building and on-site findings.
Inspection and cleaning answer different questions
An inspection evaluates condition within its stated scope. Cleaning removes deposits and accessible obstructions. They are often booked together but are not interchangeable. Ask the company to identify both tasks in the estimate so an appointment described as a check does not leave a cleaning expectation unresolved.
Start with annual assessment
CSIA homeowner guidance recommends at least annual inspection of chimneys, fireplaces and vents, with cleaning and repair when necessary. This is a planning baseline, not permission to ignore new symptoms until an anniversary. Appliance manuals and findings can call for additional maintenance or earlier attention.
Usage changes the conversation
Tell the professional whether the appliance is a main heat source or occasionally used, which fuel is burned and what the prior inspection found. A calendar alone cannot establish deposit condition. A heavily used system and an occasional-use fireplace may require different cleaning plans even when both need regular inspection.
An idle system still has a history
A long period without use does not establish that the vent remains clear or undamaged. Share known weather damage, animal activity and changes to appliances or the building. Ask what inspection is appropriate before restarting a dormant system, especially when service records are missing.
Act on changed conditions
Smoke indoors, a carbon-monoxide alarm, a suspected fire or other immediate hazard requires action now, not a future maintenance reminder. Stop use and contact emergency services for an active hazard. For non-emergency changes, request an appropriate assessment and preserve the observation without testing the appliance again.

Questions answered
Chimney service FAQs
Is annual inspection the same as annual sweeping?
No. Inspection evaluates condition within its scope. The need for cleaning depends on deposits, system condition, appliance instructions and use.
Should I wait until the next appointment if smoke appears?
No. Stop use and address the concern promptly. For active smoke accumulation, a CO alarm or fire concern, leave and contact emergency services.
Does occasional use remove the need for inspection?
No. Low use does not establish that a vent is unobstructed or undamaged. Share the actual history with the inspector.
Can one reminder cover every appliance?
Keep a separate model and service history for each system. Manufacturer maintenance tasks and service intervals may differ.
