Indoor Air Quality

Common signs of poor indoor air quality include excessive dust buildup, musty odors, frequent allergy or asthma flare-ups, dry or irritated eyes, headaches, and increased respiratory issues, especially when you're indoors. You may also notice uneven humidity, lingering smells, or that your HVAC system is constantly running. If your home feels stuffy or symptoms improve when you leave the house, it's a strong indicator that your indoor air could use attention.

Our team can assess your air quality and recommend solutions like purification systems, duct cleaning, or improved filtration to help you breathe easier.

Yes. Poor indoor air quality can have a significant impact on your health, especially if you or your family members suffer from allergies, asthma, or other respiratory conditions. Dust, pollen, pet dander, mold spores, and even bacteria and viruses can circulate through your home and trigger symptoms like sneezing, coughing, headaches, fatigue, and irritated eyes or throat.

Over time, continued exposure to polluted indoor air can contribute to chronic health issues or make existing conditions worse. Improving your home’s air quality with proper filtration, air purification, and regular HVAC maintenance can make a noticeable difference in your comfort and overall well-being.

Improving your indoor air quality starts with a few simple steps, like regularly replacing your HVAC filter, keeping your home clean and well-ventilated, and scheduling routine maintenance on your heating and cooling systems.

During allergy season or wildfire smoke events, indoor air quality becomes even more important. That’s when whole-home solutions like the iWave Residential Air Cleaner or Air Scrubber can make a big difference by reducing airborne particles, allergens, odors, and contaminants.

Not sure where to start? We’ll help you choose the best solution based on your home, your system, and the seasons you're up against.

Yes! Your HVAC system plays a major role in your home’s air quality. It continuously circulates air, so if it's equipped with the right filters, kept clean, and maintained properly, it can help reduce dust, allergens, and airborne pollutants.

Adding whole-home air purification systems or upgraded filtration can further enhance how your system supports a healthier indoor environment.

Regular maintenance is also key. That’s why we include indoor air quality checks as part of our Love Club Maintenance Program, which ensures your system stays clean, efficient, and ready to help you breathe easier year-round.

Air filters trap dust, pollen, and other particles as air passes through your HVAC system—helping protect your equipment and reduce airborne allergens. They're your system’s first line of defense and should be replaced regularly to maintain good airflow and performance.

Air purifiers, on the other hand, go a step further. These systems actively remove or neutralize contaminants like bacteria, viruses, odors, and even smoke particles from the air. Whole-home air purifiers work alongside your HVAC system to clean the air throughout your entire home, not just in one room.

Using both together offers the best results, with filters catching larger particles and purifiers handling the microscopic ones that affect your health and comfort.

Yes, we do. DeHart offers indoor air quality assessments to help identify potential issues like excess dust, poor ventilation, allergens, or airborne contaminants in your home.

We’ll evaluate your current HVAC system, check filter conditions, and recommend customized solutions, whether it’s upgraded filtration, air purification, duct cleaning, or humidity control to help you breathe easier and live more comfortably.

In most homes, air filters should be replaced every 1 to 3 months, depending on the type of filter, your system, and household factors like pets, allergies, or indoor air quality concerns.

If you have a high-efficiency filter, it may last longer but it’s always a good idea to check it monthly and replace it when it looks dirty.

Regular filter changes help your system run efficiently, reduce wear and tear, and improve your home’s air quality.

And to make it even easier, you can now order filters directly through our website. Our online filter store lets you browse the right sizes and types for your system, and even subscribe for auto-delivery, so you never forget to replace them again.

Yes, when performed by trained professionals using the right equipment, duct cleaning is completely safe for your HVAC system. It can actually improve performance by clearing out dust, debris, and allergens that restrict airflow and strain your system.

At DeHart, we use specialized tools and methods that are designed to clean thoroughly without damaging your ductwork or components so you can breathe easier and help your system run more efficiently.

Right now, we’re offering $250 off professional duct cleaning, making it a great time to schedule this important service.

In general, air ducts should be professionally cleaned every 3 to 5 years, depending on your home's conditions. However, you may need more frequent cleaning if you have pets, allergies, recent renovations, or notice visible dust or mold around vents.

Regular duct cleaning helps improve indoor air quality, reduce allergens, and keep your HVAC system running efficiently.

DeHart offers expert duct cleaning and right now, you can save $250 with our current promotion.

We don’t offer dryer vent cleaning as a standalone service, but it can be added on when you schedule a full home duct cleaning.

Costs can vary based on your home and the solution that’s right for you. Basic upgrades like high-efficiency filters are relatively inexpensive, while whole-home air purification systems typically range from a few hundred to over a thousand dollars.

Professional duct cleaning is another valuable service that can improve both air quality and HVAC system performance. Pricing depends on the size and layout of your home, but we always provide upfront estimates and right now, we’re offering $250 off duct cleaning to make it even more affordable.
