Why Pellet Stove Service Matters?
Your pellet stove is a high-efficiency heating appliance that relies on clean airways, precise fuel delivery, and sealed venting. Regular service keeps it safe, efficient, and long-lived, just like a car needs oil changes.
Regular Cleaning of Your Pellet Unit is Essential
Frequent upkeep is essential for proper operation of a pellet appliance. Sometimes it is difficult to keep up with the vacuuming required for pellet stoves. Thankfully, you can set a pellet unit and forget it each day. Pellet is an excellent option for folks who need to be away from home most of the day.
Make sure to get your pellet stove serviced by a professional who has completed their pellet certification through the National Fireplace Institute. Continued education is a good sign of a high quality pellet service tech.
Regular Cleaning (Homeowner Maintenance)
Every 4–6 Weeks or Every Ton of Pellets Burned
Empty the Ash Pan: Ash restricts airflow and reduces efficiency.
Clean the Burn Pot: Use a scraper to remove clinkers and hardened ash.
Brush the Heat Exchanger: Pull the rod or brush manually to remove buildup.
Vacuum the Firebox: Use a metal, ash-rated vacuum only.
Wipe Door Glass: Use a damp paper towel dipped in ash (natural abrasive).
Check Door and Ash Pan Gaskets: If they feel flat, frayed, or hard. Time to replace.
If you burn low quality, high-ash pellets, clean the vent pipe monthly.

Annual Professional Service (Technician Maintenance)
(Recommended every 12 months, ideally after heating season.)
A certified hearth technician will:
Disassemble and deep-clean the combustion and convection blowers.
Brush and vacuum the entire venting system from stove to cap.
Inspect the auger motor, vacuum switch, and igniter for wear.
Check all gaskets, seals, and sensors for leaks or damage.
Verify electrical components and control board operation.
Reassemble and test-fire the unit for safe startup and combustion quality.
Per NFPA 211, chimneys, vents, and connectors must be inspected annually and cleaned or repaired as necessary.
Off-Season Storage (End-of-Season Steps)
Burn remaining pellets and allow the stove to cool completely.
Unplug and vacuum all ash compartments and vents.
Empty and wipe down the hopper pellets absorb summer humidity.
Clean the glass and polish the exterior with a dry microfiber cloth.
Leave the door slightly open to relieve gasket compression.
Cover the vent termination to prevent rain or nesting animals.
These steps prevent rust, odor, and moisture damage during summer.
Signs You Need Earlier Service
If you notice any of these, call us before your annual cleaning:
Flame turns lazy or orange (not bright yellow-white).
Soot builds up quickly on glass.
Smoke odor during startup or shutdown.
Louder-than-normal fan noise or rattling.
Error codes for “vacuum” or “airflow.”
Watch for Component Wear
Combustion Blower:
Noisy, slow to start, or failing to maintain flame draft.
Triggers vacuum-switch faults.
Auger Motor:
Uneven feeding or loud “grinding” sounds.
Heat buildup or electrical smell.
Both motors typically last 5-8 years under daily winter use.
