UV Lights in Redmond, OR
Keeping the air in your Redmond home clean and your HVAC system running efficiently is a top priority for comfort and health. Ultraviolet (UV) light air treatment for HVAC systems is a proven way to reduce microbial growth on coils and in ducts, control odors, and help your system operate closer to its designed efficiency. Mountain View Heating, Inc. offers advanced UV light solutions that improve air quality and HVAC performance. This guide explains how UV lights work, the installation options for Redmond homes, maintenance expectations, and the health and efficiency benefits they provide.
Why UV Light Matters for Redmond Homes
Redmond and Central Oregon’s environment—with dry, dusty summers and smoky air from wildfire season—creates ideal conditions for contaminants to develop. Cooler, humid periods also lead to condensation within HVAC systems. These conditions can cause:
- Dust and particulates to build up on coils and ducts
- Moisture on evaporator coils and drain pans encouraging microbial growth
- Musty odors or recurring allergens during cooling seasons
Mountain View Heating, Inc. installs UV lights that target bacteria, mold, and certain viruses thriving on moist HVAC surfaces. Proper UV exposure prevents microbial growth, minimizing odors and improving indoor air quality.

Common UV Light Installation Types
Coil-Mounted (In-Evaporator) UV Lights
- Installed near the evaporator coil and drain pan inside the air handler.
- Purpose: Prevent and remove microbial growth on coils and in pans where moisture accumulates.
- Benefits: Reduces musty smells, improves condensate drainage, and maintains efficient heat transfer.
In-Duct UV Lights
- Mounted within the supply or return ductwork to treat circulating air.
- Purpose: Reduce airborne microbial load and keep duct interiors cleaner.
- Ideal for long duct systems or homes with occupants sensitive to airborne contaminants.
Additional Options
- Upper-Room UV Systems: More common in commercial environments, these are used for specific residential needs and require careful safety design.
- LED UV Modules: Modern alternatives offering long life, low heat, and energy efficiency compared to mercury-based lamps.
How Professional Installation and Sizing Work
Installing UV lights correctly requires expertise. Mountain View Heating, Inc. ensures every system is custom-fitted for optimal results by focusing on:
- Placement: Coil UVs face the coil and drain pan for maximum coverage; duct UVs are positioned for optimal airflow and dwell time.
- Lamp Strength and Quantity: Based on coil size, duct dimensions, and contamination levels.
- Mounting and Electrical Setup: Using corrosion-resistant hardware and properly rated components.
- Airflow and Exposure Time: Adjusted for system speed and duct design.
- System Compatibility: Some systems may need custom brackets or protective sleeves.
Professional technicians from Mountain View Heating, Inc. evaluate your HVAC layout, ensuring effective UV dosage where it’s needed most.
Safety Considerations
UV-C light (around 253.7 nm) effectively neutralizes microbes but must be used safely:
- Only ozone-free lamps (standard 254 nm) should be used—avoid any emitting at 185 nm.
- Lamps must remain enclosed within air handlers or ducts to prevent exposure.
- Access panels should be labeled, and protective shielding should be used near sensitive materials.
- If upper-room UV systems are applied, designs must follow established safety standards.
Maintenance and Replacement Schedule
UV systems require minimal maintenance but consistent care to remain effective:
- Lamp Replacement: Replace annually (every 9–12 months) or as recommended. LED models may last several years but should be checked periodically.
- Cleaning: Dust or soot buildup reduces output—inspect every 3–6 months, especially during Redmond’s dusty summers.
- Electrical Components: Ballasts or drivers should be checked every few years and replaced if flickering.
- Performance Testing: Use a UV-C meter every 1–2 years to ensure proper dosage.
- Coil and Drain Pan Inspection: UV lights prevent growth but do not replace deep cleaning when heavy buildup exists.
Expected Results and Benefits
When Mountain View Heating, Inc. installs a UV system, homeowners typically notice:
- Reduced microbial growth and odors around coils and drains.
- Improved airflow and heat transfer for enhanced efficiency.
- Potential energy savings due to cleaner, more efficient coils.
- Better indoor air quality, easing allergies and respiratory discomfort.
- Extended equipment lifespan and fewer service calls.
When UV Lights Are the Right Choice
You should consider UV installation from Mountain View Heating, Inc. if you experience:
- Persistent musty odors when your air handler operates
- Mold or slime near evaporator coils or drain pans
- Increased allergy symptoms when cooling
- Frequent but short-lived coil cleanings
- Reduced HVAC performance due to biological buildup
In Redmond’s climate—marked by dust and smoke—UV systems are a valuable addition for maintaining HVAC efficiency and cleaner indoor air.
