Dryer Vent
According to the newsletter the dryer vents should be cleaned every 2 years, but the letter from Patterson Merkle states that they need to be done biannually ( which is twice a year) which is correct?

Just to clarify:
Key Terms Explained:
Biannual: Twice per year (e.g., twice-yearly meetings).
Biennial: Once every two years (e.g., a biennial report due every other year).
Semiannual: Twice a year, usually every six months (e.g., semiannual reports).
Example: A biannual sale happens twice a year, while a biennial convention happens every two years.
