Indoor air can often be more polluted than outdoor air. Yup, you read that right. Dust, allergens, mold spores, and even everyday household products all impact the air you breathe. Add in our damp Pacific Northwest climate, and it’s no wonder many homeowners deal with musty smells, allergies, and humidity problems.
At NW Energy Conservation, we provide complete indoor air quality (IAQ) and ventilation solutions for homes and businesses across Tacoma, Seattle, Renton, Puyallup, and the greater Puget Sound. From UV air purifiers and advanced filtration to bathroom exhaust fans and whole-home HRV/ERV systems, we’ll help you breathe easier, live healthier, and keep your indoor environment safe year-round.
Our region is known for fresh outdoor air - but indoors can be a different story.
Humidity & Mold: Tacoma, Seattle, and Puyallup homes often deal with high humidity that encourages mold growth inside ducts, crawlspaces, and basements.
Wildfire Smoke: In summer, wildfire smoke can travel across Puget Sound and infiltrate homes through leaky ducts or poor filtration. It can then stay there, being constantly inhaled.
Older Homes: Many historic homes in Seattle and Tacoma lack proper ventilation, trapping pollutants inside. This can lead to health issues down the road.
Energy-Efficient Homes: Newer “tight” homes are great for saving energy but can also trap stale air if they’re not paired with the right ventilation system.
Improving indoor air quality isn’t just about comfort - it’s about protecting your family’s health!
UV air purifiers help neutralize bacteria, viruses, and mold spores inside your HVAC system before they circulate through your home. Installed directly in ductwork, they work silently to disinfect the air you breathe.
• Destroys airborne germs at the source
• Reduces mold growth on coils and ducts
• Improves allergy and asthma symptoms
• Works 24/7 without adding noise
Local Tip: In damp basements and crawlspaces in Tacoma and nearby cities, we've found that UV systems are especially effective at reducing mold growth, improving indoor air quality.
Standard filters only catch the big stuff - dust and lint. For real indoor air quality improvement, we install advanced filtration systems like Honeywell filters, Aprilaire media filters, and HEPA upgrades. These have a much greater ability to:
• Capture tiny particles (pollen, smoke, pet dander) • Reduce odors and chemical VOCs • Protect your HVAC equipment from dust buildup
Sometimes the solution isn’t just filtering - it’s adding fresh air.
HRV (Heat Recovery Ventilator): Brings in fresh outdoor air while conserving heating/cooling energy.
ERV (Energy Recovery Ventilator): Adds humidity control, perfect for damp PNW winters.
These systems are ideal for energy-efficient or airtight homes in Seattle, Tacoma, and surrounding cities. They continuously refresh indoor air, reduce odors, and keep humidity levels balanced.
Balanced humidity is key to comfort and health. Too much = mold and musty smells. Too little = dry skin and static. We install whole-home humidifiers and dehumidifiers to keep levels consistent year-round.
Winter: Add moisture to dry heated air
Summer: Remove excess humidity to stop mold and mildew
This also protects wood floors, furniture, and musical instruments
