Cleaner, Healthier Air Starts with Dragonfly Heating & Cooling

Ontario, CA is known for its vibrant community, beautiful outdoor spaces like Cucamonga-Guasti Regional Park, and entertainment hotspots such as Toyota Arena. But while residents enjoy what the city has to offer, many are unaware that the air inside their homes could be more polluted than the air outside.

At Dragonfly Heating & Cooling, we work to improve indoor air quality in Ontario, CA. Our IAQ solutions help homeowners reduce airborne contaminants, control humidity, and breathe easier – no matter what’s happening outdoors.

Why Indoor Air Quality Matters in Ontario, CA

According to the EPA, indoor air can be up to five times more polluted than outdoor air. Modern construction practices – while great for energy efficiency – can trap airborne pollutants inside your home, recirculating dust, dander, allergens, and volatile organic compounds (VOCs).

Common indoor air quality concerns include:

  • Persistent allergy or asthma symptoms
  • Unexplained headaches or fatigue
  • Dry skin, itchy eyes, or sinus irritation
  • Musty odors and visible mold
  • Lingering dust even after cleaning

Humidity plays a major role, too. Air that’s too dry causes discomfort, while excessive humidity encourages mold growth and respiratory issues. A well-balanced indoor environment promotes comfort, better health, and even improved HVAC system performance.

Our IAQ Solutions for Ontario Residents

Dragonfly provides expert, customized indoor air quality services designed for the Inland Empire’s unique climate and air quality conditions.

Humidity Control

Ideal indoor humidity should range between 30% and 50%. We install whole-home humidifiers and dehumidifiers that help prevent mold growth, protect wooden surfaces, and keep your indoor environment comfortable year-round.

Air Purification Systems

Our advanced air purifiers remove pollutants such as dust, pet dander, pollen, smoke particles, and microscopic pathogens. We offer both standalone and integrated solutions that work alongside your HVAC system for full-home protection.

Allergen Filtration

We help you upgrade your HVAC filters or install high-performance filter systems to capture airborne allergens before they circulate through your space. Ideal for homes with pets, children, or allergy-prone occupants.

HEPA Filtration & UV Light Technology

For enhances protection, we combine HEPA filters with UV light systems that neutralize bacteria, mold spores, and viruses. This powerful duo is especially beneficial for homes where air quality is a serious health priority.

Signs You May Need IAQ Help

Not sure if your indoor air quality is causing issues? Here are common signs to watch for:

  • You experience worsened allergy or asthma symptoms indoors
  • There’s a lingering musty or chemical smell in the home
  • Your home has recently undergone renovations or construction

Great business and they have employed very polite and capable technicians.
Response from the owner:Thank you so much for taking the time to leave us a 5 star review!
I always request Dustin, who has been doing regular annual maintenance on our mini split AC/heating system in our tenant's unit for years since it first had leaking issues. He takes pride in the work he does and takes his time to do a thorough job. Not many companies work on mini splits, so I was happy to find a reliable company I can call when needed. He was also able to flush my water heater as well and make sure everything was running smoothly. Everyone at Dragonfly has been really friendly and I highly recommend this company.

Dustin did a great job diagnosing and fixing my heater, which had a bad connection. He was professional, efficient, and took the time to explain the issue. He also recommended swapping out the board while we still have time, which I appreciate. Solid service and honest advice—definitely recommend!

Got a concrete patio put in where my condenser units were and Dragon Fly came out to lift my units while the pad was poured. My concrete guy didn’t even realize that was an option. Super friendly and professional staff. Highly recommend these guys.
