Frequently Asked Questions

For most homes, professional air duct cleaning is recommended every 1–3 years. Homes with pets, allergies, higher dust levels, or recent renovations may benefit from more frequent cleaning. The exact timing depends on system usage and overall household conditions.

Dryer vent cleaning is typically recommended once per year for normal households with average laundry use and no pets. Homes with pets, large families, or heavy laundry usage should have their dryer vents cleaned every 6 months to maintain proper airflow and reduce fire risk.

Lint and debris buildup inside dryer vents restrict airflow, causing dryers to overheat, take longer to dry clothes, and use more energy. Clogged dryer vents are also a common cause of household fires. Regular dryer vent cleaning improves efficiency and helps keep your home safe.

Furnace cleaning frequency depends on how well the system is maintained. Homes with regular filter changes and proper maintenance may only need cleaning every 2–3 years. Systems with pets, infrequent filter changes, or heavy usage may benefit from cleaning every 1–2 years.

AC and evaporator coil cleaning is recommended based on system condition and maintenance habits. Dirty coils reduce airflow and efficiency. Well-maintained systems may only need cleaning every 2–3 years, while neglected systems or homes with pets may require more frequent service.

Common signs include excessive dust in the home, visible dust around vents, musty odors when the system runs, reduced airflow, or worsening allergy symptoms. If it’s been several years since your last cleaning, an inspection may be beneficial.

Signs of a clogged dryer vent include longer drying times, excessive heat from the dryer, a burning smell, lint buildup around the vent opening, or the dryer shutting off mid-cycle. These issues should be addressed promptly for safety reasons.

Air duct cleaning can help reduce dust, pet dander, and other airborne particles that circulate through your HVAC system. While it is not a cure for allergies, many homeowners notice improved indoor air quality after professional cleaning.
