Final Thoughts
Frequently Asked Questions (FAQ)
1. How often should I schedule air duct cleaning in Fort Collins?
Every 3 to 5 years is recommended, but if you have pets, allergies, or recent renovations, cleaning every 2 to 3 years is ideal. Fort Collins’ dry air and pollen levels can accelerate dust buildup, making more frequent service a smart move for cleaner air and better HVAC performance.
