OUR INDOOR AIR QUALITY SERVICES
A Whole Home Approach to cleaner, healthier air
Indoor air quality is rarely solved by a single product. Marble City Heating & Air takes a whole-home approach that improves airflow, filtration, and system performance, based on what is actually happening inside your home.
Indoor Air Quality Testing
We start with data. IAQ testing helps identify what is circulating through your home, including fine particles, pet dander, and volatile organic compounds from common household products and materials. Using professional-grade tools, we pinpoint the issues and recommend targeted solutions that match your health and comfort goals.
Air Duct Repair
Leaky or damaged ducts waste energy and can spread dust and contaminants. Our duct repair focuses on sealing, reconnecting, and insulating ductwork to restore proper airflow, reduce dust infiltration, and help your HVAC system deliver cleaner air more efficiently.
Air Duct Installation
If your ductwork is beyond repair or your home needs a better distribution layout, we design and install new duct systems that balance airflow from room to room. Proper duct design improves comfort, reduces hot and cold spots, and supports better filtration and air cleaning across the entire home.
Home Energy Audit
Air quality issues often connect to hidden problems like poor insulation, inadequate ventilation, or pressure imbalances. A home energy audit helps identify where your home is leaking air, where stale air is trapped, and what upgrades will make the biggest difference for comfort, health, and efficiency.
Not sure where to start? We will help you prioritize the highest-impact improvements based on your symptoms, home layout, and budget.
FAQ
Frequently Asked Questions
Clear answers to common questions about filtration, purification, ductwork, and indoor air health.
What is the difference between air purifiers and air filters
Air filters primarily trap particles like dust, pollen, and pet dander as air moves through your HVAC system. Air purifiers go further by actively reducing certain pollutants using technologies such as UV, activated carbon, or ionization. The right setup depends on your goals and what testing or symptoms suggest.
How do whole-home air purification systems work with my HVAC
Whole-home systems integrate into your ductwork or air handler and treat air as it circulates through the HVAC system. That means every room benefits, not just a single space like with a portable unit. We verify compatibility and airflow so the system performs properly without stressing equipment.
What are VOCs and how can I reduce them in my home
VOCs are gases released by items like paint, furniture, flooring, and many cleaning products. Reducing VOCs usually involves improving ventilation, choosing low-VOC materials, and using high-efficiency filtration or purification that can absorb or neutralize certain compounds.
Why do some rooms feel dusty even when I change filters
Persistent dust often points to duct leakage, poor return airflow, gaps in the filtration path, or insulation and debris entering the system from attics or crawlspaces. Sealing ducts, improving returns, and ensuring a proper filter fit can make a big difference.
How often should I replace HVAC filters
Most homes do well with replacement every 1 to 3 months depending on pets, allergies, and usage. Higher-MERV filters may need more frequent changes if airflow is restricted. We can recommend the best filter type and replacement schedule for your system.
