Common Questions About Indoor Air Quality Answered

What is indoor air quality, and why does it matter?

Indoor air quality refers to the cleanliness and overall condition of the air inside your home. Poor air quality can cause or worsen respiratory issues, allergies, and discomfort, especially for children, seniors, or individuals with asthma.

How can I tell if my home has poor air quality?

Common signs include musty odors, excessive dust buildup, uneven temperatures, or worsened allergy symptoms. If your HVAC system runs constantly but comfort doesn’t improve, that could be another sign.

What are common indoor air pollutants?

Dust mites, mold spores, pet dander, pollen, cleaning chemicals, and tobacco smoke are some of the most prevalent.

How often should I change my HVAC air filter?

Most standard filters should be replaced every 1 to 3 months. Homes with pets or allergy concerns may need more frequent changes.

Do air purifiers really help improve indoor air quality?

Yes—when sized and installed correctly, whole-home air purifiers can trap or neutralize airborne particles and reduce allergens and pathogens.

Humidity, Allergens, and Specialized Equipment

What is the ideal humidity level for indoor air?

The recommended range is between 30% and 50%. Below this range, dry air can irritate your skin and lungs. Above it, mold and dust mites thrive. We can install humidifiers or dehumidifiers to keep it balanced.

How can I reduce allergens in my home?

Use HEPA filters, wash bedding frequently in hot water, and vacuum with a sealed, HEPA-grade vacuum. Sealing ducts and regular HVAC maintenance also helps limit dust and allergens from circulating.

What role do UV germicidal lights play in air quality?

UV lights installed in HVAC systems kill mold spores, bacteria, and viruses as air passes through. They’re especially useful in humid climates or homes with recurring mold or allergy issues.

Should I invest in a whole-home air purifier?

If you have respiratory issues, pets, or live in a high-pollen area like Lawrenceville, a whole-home purifier can be a worthwhile investment. These systems work 24/7 and treat every room, unlike portable units.

Choosing the Right Tools for Your Indoor Air

What’s the difference between a humidifier and a dehumidifier?

A humidifier adds moisture to dry indoor air, which helps in winter or arid climates. A dehumidifier removes excess moisture, which prevents mold and helps homes feel cooler and less sticky in summer.

Each home has unique needs, and we can help assess whether you need one, both, or none depending on your home’s conditions.

At Wall Heating & Air Conditioning, our team works with trusted products and provides honest recommendations—whether it’s advanced filtration systems, upgraded HVAC filters, or air quality monitors. We take time to explain options in plain terms, so you feel confident about your home’s health and comfort.
