Problems crews often find
These issues come up regularly during cleanings.
- Missing or damaged filters
- Ducts without enough access panels
- Fans without hinge kits
- Worn or loose fan belts
- Overflowing rooftop containment
- Grease leaking from duct seams
Why they matter
Each of these either lets grease build where it should not or makes the system harder to clean. Addressing them makes future cleanings more complete.
Final tips
Many of these problems start small, so a quick look at the fan and filters each month can catch them early.
When a problem keeps coming back after cleaning, the cause is often airflow or access, which is worth raising with your contractor.
