What Should I Do Before and After Getting My Air Ducts Cleaned?

Air duct cleaning is a smart move for improving indoor air quality, HVAC efficiency, and even reducing allergens in your home. But to get the most from your service, it helps to know what to do before and after the professionals arrive. Here's your complete guide on how to prepare and what to expect afterward.

✅ Before Air Duct Cleaning: How to Prepare Your Home

1. Clear the Area Around Vents and Ducts
Move furniture, rugs, or anything blocking access to air vents or return registers. This allows the technicians to work quickly and safely.

2. Secure Pets in Another Room
The equipment can be loud, and technicians will need to move in and out. To keep your pets safe and stress-free, place them in a closed room or outside during the service.

3. Make a List of Problem Areas
Have you noticed musty odors, poor airflow, or more dust in certain rooms? Let the technician know in advance so they can inspect those areas more closely.

4. Ask About Pre-Inspection
Some companies perform a pre-cleaning inspection to check for mold, debris, or damage. Ask if your provider offers this, so you know what you're dealing with.

5. Replace Your Air Filter (Optional)
If it’s been a while, consider replacing your air filter. Or, ask your duct cleaning company if they offer filter replacement as part of the service.

🚫 What NOT to Do Before Duct Cleaning

• Don’t run your HVAC system an hour before the appointment.

• Don’t block driveway access if the company uses truck-mounted vacuums.

✅ After Air Duct Cleaning: Steps to Take Next

1. Inspect the Work
Check the vents, duct covers, and surrounding areas. Everything should be clean and free of debris. Don’t hesitate to ask the technician for a walkthrough or before-and-after photos.

2. Change the HVAC Filter
If it wasn’t replaced during the service, now’s a good time. A clean system deserves a clean filter to keep things running smoothly.

3. Run the System
Turn your HVAC system on to make sure airflow feels stronger and more consistent. This also helps remove any remaining particles that may have loosened during cleaning.

4. Monitor Indoor Air Quality
You may notice less dust on surfaces, improved airflow, or reduced allergy symptoms. Keep an eye out and consider scheduling regular maintenance going forward.

5. Schedule the Next Cleaning
Most homes benefit from air duct cleaning every 3–5 years. Mark your calendar or set a reminder to stay ahead of dust buildup and keep your HVAC system running efficiently.

If your ducts had mold, bacteria, or foul odors, ask your technician about sanitizing options. Some companies offer safe, EPA-approved treatments that kill lingering microbes.

Preparing your home before a duct cleaning — and knowing what to do afterward — helps ensure the best results. Clean air ducts don’t just make your HVAC system more efficient, they help create a healthier, more comfortable living space.
