Air Quality & Ductwork Services


If you’re dealing with dusty air, uneven temperatures, or allergies that won’t go away, your home or business may need better air quality solutions. At Steve Patrick Air, we specialize in complete air quality and ductwork services for homes, offices, and commercial buildings across Fresno, Clovis, and the Central Valley. Our goal is to deliver cleaner, healthier air—while helping your HVAC system run more efficiently.

Why Indoor Air Quality Matters in the Central Valley

The Central Valley is known for extreme weather, dust, and pollen. Combine that with smoke from wildfire season and poorly sealed buildings, and you’ve got a recipe for indoor air problems. Clean indoor air can improve sleep, reduce asthma and allergy symptoms, and lower your monthly energy bills. We take a whole-system approach to improve your air quality—from ductwork to filtration—so you get cleaner, more breathable air every day.

Air Duct Installation

Your ductwork plays a critical role in distributing clean air throughout your home or business. Improperly sized or outdated ducts reduce airflow and force your HVAC system to work harder. We custom design and install duct systems for maximum performance, airflow, and energy savings.
We ensure every connection, angle, and register is placed for efficient operation and long-term reliability.

Air Duct Sealing

Leaky ducts can waste up to 30% of your HVAC system’s energy output. That means you’re paying more for conditioned air that never reaches its destination. Our duct sealing service locates and eliminates leaks using professional-grade materials and equipment.
After sealing, your system uses less energy, reduces noise, and delivers consistent temperatures in every room.

Air Filtration Systems

Standard air filters only catch the largest particles. Our advanced filtration systems go further—removing dust, pollen, mold spores, and bacteria from your indoor air. We offer high-performance filters including MERV-rated and electronic air cleaners to match your needs.
Cleaner air leads to better respiratory health, improved system longevity, and less frequent filter changes.

Whole-House Humidifiers

Dry indoor air—especially in the winter—can cause dry skin, respiratory irritation, and static buildup. A whole-house humidifier helps balance moisture levels throughout your home, improving health and protecting wood furniture, floors, and instruments.
We install smart, efficient humidifiers that integrate directly with your existing HVAC system.

Dehumidifiers

If your home feels damp, musty, or shows signs of mold or mildew, excess humidity may be the culprit. A whole-house dehumidifier removes moisture from the air, reducing mold growth, improving comfort, and helping your AC system work more effectively.
Our technicians evaluate your humidity levels and recommend the right solution to balance your air.

Indoor Air Quality Testing

You can’t fix what you can’t see. That’s why we offer professional indoor air quality testing using state-of-the-art diagnostic tools. We measure airborne particulates, carbon monoxide, humidity, and volatile organic compounds (VOCs).
With the data in hand, we build a custom plan to clean and balance your air safely and effectively.
