Summer in Texas is no joke. Your A/C becomes the MVP of your home — but even the best system can struggle if your air ducts are packed with dust, debris, or that weird mystery fluff no one wants to talk about.
Most homeowners forget about their ductwork because it’s out of sight. But if you’re a hardcore DIYer (and not afraid of a little dust), cleaning your air ducts yourself is absolutely doable. Here’s how to prep your home for summer and breathe cleaner, cooler air all season long.
Tools & Supplies You’ll Need For Air Duct Cleaning
Before you start your duct-cleaning adventure, gather your gear:
Screwdriver or drill (for vent covers)
Shop vac or heavy-duty vacuum with a long hose
Stiff-bristle brush or dryer vent brush
Microfiber cloths
Flashlight or headlamp
Non-toxic cleaner (like white vinegar or plant-based cleaning spray)
Gloves + dust mask
Optional: ladder or step stool for high vents
The Best Non-Toxic Cleaner for the Job
You don’t need harsh chemicals inside your ductwork. A simple 50/50 mix of white vinegar and water works surprisingly well. For a more “spa day for your ducts” vibe, try a fragrance-free, plant-based cleaner like Seventh Generation Free & Clear.
These options clean grime without leaving behind residue that could irritate allergies or reduce indoor air quality.
Step-by-Step DIY Air Duct Cleaning (Texas Edition)
Turn Off Your HVAC System
Safety first! You don’t want a blast of air turning duct dust into a confetti cannon while you’re working.
Remove and Clean the Vent Covers
Unscrew the vent covers and wash them in warm, soapy water. Let them dry completely — moisture + dust = trouble later.
Vacuum Inside the Ducts
Use your vacuum hose to reach as far inside the duct as possible. Move slowly to loosen dust and debris without damaging the duct interior.
Scrub What You Can Reach
Wrap a microfiber cloth around your brush, spray with non-toxic cleaner, and gently wipe down the duct walls. If you can reach it, you can clean it.
Clean Around the Vent Area
Dust the walls, floors, and trim around the vent. Why clean the ducts if the dust outside just falls back in?
Replace Vent Covers & Restart Your System
Turn your system back on and enjoy that fresh, clean airflow. If your allergies don’t thank you, your A/C efficiency will.
Pro Tips to Keep Your Ducts Cleaner, Longer
Change your air filter right after cleaning the ducts.
Clean ducts once a year, or every 6 months if you have pets or allergies.
If you see signs of mold, pests, or excessive debris, skip the DIY — call in the pros.
Keep humidity under control; Houston humidity can encourage microbial growth inside ducts.
When DIY Isn’t Enough
Some ductwork issues need professional tools and training — especially if you notice:
Strong musty smells
Visible mold
Poor airflow throughout the home
Pest evidence in the vents
Thick, packed debris deeper in the duct system
In these cases, a professional duct cleaning helps protect your air quality and HVAC system.
