Indoor Air Quality Services in Gaithersburg, MD
Indoor air quality affects how your home feels, how you sleep, and how healthy your family stays year-round. Everyday activities like cooking, cleaning, bathing, and even breathing add moisture and particles to the air. Without the right solutions, those pollutants can build up inside, aggravating allergies and asthma and making rooms feel stale or stuffy.
At Michael Bonsby HVAC, Plumbing & Electrical, we help DMV homeowners identify the sources of poor indoor air quality and match them with proven fixes. From whole-home humidifiers and air cleaners to germ-killing UV light systems, our team designs IAQ solutions that work with your HVAC equipment—not against it.
Whether you’re fighting dry winter air, high summer humidity, lingering odors, or constant dust, our experts can tailor a plan to improve your home’s indoor air quality. Contact us today to get clear recommendations and a no-pressure estimate.
Types of IAQ Systems
Humidifiers
Balanced humidity is essential to indoor air quality. Maryland’s sticky summers and dry winters can swing your indoor humidity far outside the ideal 30%–50% range. Low humidity dries out skin and sinuses and can make your home feel colder than it is; high humidity fuels mold growth and dust mites. Our whole-home humidifiers integrate with your ductwork to add just the right amount of moisture, improving comfort and supporting your heating system’s efficiency.
Benefits of proper humidification include:
- Relief from coughs, colds, and allergy symptoms
- Reduced static electricity and dry-air irritation
- Protection for wood floors and furniture
- More comfortable warmth at lower thermostat settings
Air Purifiers

If odors, smoke, or fine dust are your main concerns, a whole-home air purifier can dramatically improve indoor air quality. These systems pull air through high-efficiency media to capture fine particles and can include activated carbon for odors and VOCs. For households with asthma or allergies, a purifier paired with a quality filter helps keep triggers under control.
Choosing the right purifier: If seasonal allergies are the issue, look for high-MERV or HEPA-grade filtration. For strong odors, carbon media is helpful. For households concerned about microbes, see UV options below.
UV Light Systems
UV-C technology helps neutralize airborne microbes that standard filters can’t stop. Our UV light systems bathe the coil and passing air in germicidal light to reduce bacteria, viruses, and mold spores—supporting cleaner coils, steadier airflow, and better indoor air quality. We often pair UV with air cleaners to address particles, gases, and biologicals together.
