How to Improve Indoor Air Quality During AC Installation
When it comes to making your home healthier and more comfortable, indoor air quality (IAQ) matters. One of the best times to improve your air quality is during a new air conditioner installation.
By choosing the right products and setup, your home can have cleaner, fresher air from day one. Here’s how to improve indoor air quality when installing a new AC system.
1. Choose Better Air Filters
The first step to cleaner air is using the right kind of filter.
Instead of using basic filters, upgrade to:
- Pleated filters
- HEPA filters
These filters trap more dust, pollen, allergens, and pollutants. That means cleaner air throughout your home. Choosing a high-quality filter during installation sets your system up for better air from the beginning.
2. Make Sure Your Home Has Good Ventilation
Good airflow is key to healthy air. During AC installation, it’s important to make sure your home has proper ventilation.
This includes:
- Placing air vents in the right spots
- Ensuring stale air can exit and fresh air can enter
- Avoiding areas where air gets trapped or stagnant
When your HVAC system has strong airflow, it helps remove indoor pollutants and keeps air fresh and moving.
3. Add Humidity Control
Too much or too little moisture in the air can cause problems:
- Too much humidity can lead to mold and mildew.
- Air that’s too dry can cause dry skin and breathing problems.
During installation, consider adding:
- A whole-home dehumidifier
- An AC system with built-in humidity control
Keeping humidity between 40% and 60% helps your home feel more comfortable and prevents mold growth.
4. Seal Your Ductwork
If your ducts have leaks, they can let in dust and pollutants—and your AC won’t work as well.
During installation, your HVAC technician should:
- Check for any leaks or gaps in the ducts
- Use mastic sealant or foil tape to seal them
- Replace old ductwork if it’s damaged
Sealed ducts mean cleaner air, better energy efficiency, and fewer system problems in the future.
5. Install an Air Scrubber
Want to take your air cleaning to the next level? Ask about adding an air scrubber.
Air scrubbers clean your air by removing:
- Dust
- Mold spores
- Allergens
- Germs
- Odors
- VOCs (harmful chemicals in the air)
They use UV-C light and photocatalytic oxidation to kill germs and neutralize bad particles. When installed during AC installation, air scrubbers give your home a strong layer of protection against indoor air pollution.

6. Test and Balance the System
After installing your new AC, your HVAC technician should test and balance the system.
This means they’ll:
- Check the airflow in each room
- Make sure vents are working correctly
- Look for any problems with air quality
This step ensures the system is running properly and your home is getting the cleanest air possible.
7. Learn How to Keep Air Clean with Maintenance
Your work doesn’t end after installation. To keep your indoor air quality high, you need regular maintenance.
Simple tips include:
- Changing filters regularly (every 1–3 months)
- Scheduling annual inspections
- Watching for signs of poor air quality (like odors or excess dust)
Routine care keeps your HVAC system running strong and your indoor air clean.
Final Thoughts
Installing a new air conditioning system is the perfect time to improve your indoor air quality. By choosing high-quality filters, sealing ducts, managing humidity, and adding air purification tools like air scrubbers, you can enjoy cleaner, healthier air from day one.
