What Is a UV HVAC System and How Does It Work? 

A UV HVAC system uses ultraviolet (UV-C) light to disinfect the inside of your heating and cooling system. Installed near the coils or inside the ductwork, the UV light: 

• Breaks down the DNA of mold, bacteria, and viruses 

• Prevents microbial buildup on HVAC components 

• Helps reduce allergens and improve indoor air quality 

There are two main types of UV HVAC systems: 

1. Coil sterilization systems – Positioned near the evaporator coil to stop mold growth 

2. Air sterilization systems – Positioned inside the return air duct to sanitize moving air 

The Cost Breakdown of Installing UV in HVAC 

Initial Investment: 

• Basic coil UV system: $300–$600 

• Air sterilization system: $500–$1,000 

• Installation labor: $100–$250 

Maintenance Costs: 

• Annual UV bulb replacement: $95–$150 

• Optional cleaning during service: $50–$100 

Total First-Year Cost Range: 

$400–$1,200, depending on system and services selected 

Long-Term Savings: 

• Lower utility bills from cleaner, more efficient coils 

• Fewer HVAC breakdowns and service calls 

• Better health = fewer medical costs 

Top Benefits of UV HVAC Systems 

Homeowners in NY, NJ, and CT report: 

• Fresher indoor air with reduced odors 

• Relief from allergies and asthma 

• Energy savings from reduced coil contamination 

• Fewer repairs due to mold-related breakdowns 

• Bacteria and virus elimination in recirculated air 

In areas like Brooklyn, Stamford, and Montclair, where air pollution and moisture are common, UV systems add essential protection. 

Common Misconceptions About UV HVAC Systems 

Let’s clear up some myths: 

• ❌ “They’re dangerous” — UV lights are sealed inside the HVAC system 

• ❌ “They don’t work” — Clinical studies prove microbial reductions up to 97% 

• ❌ “They’re too expensive” — ROI is earned back in energy savings and repair avoidance 

Real ROI: What Homeowners in NY/NJ/CT Experience 

EnviroGreen clients share: 

• A family in Yonkers, NY noticed fewer allergy flare-ups after a UV install 

• A homeowner in Bridgeport, CT reported lower electric bills within 3 months 

• A Hoboken condo board installed UV in common ductwork and cut maintenance calls by 40% 

These examples show how health + savings = real value. 

UV HVAC System vs. Air Purifiers and Filters

Conclusion: UV isn’t a filter—it’s a microbial solution that complements other filtration for full protection.

When Is a UV System Not Worth It? 

It may not be ideal if: 

• Your HVAC system is older than 15 years 

• Ducts are poorly sealed and leak excessively

In those cases, we recommend duct cleaning or upgrades first, before UV.

FAQs About UV System Value 

Q1: Will it work with my existing HVAC system? 
Yes, most systems are compatible with UV add-ons. 

Q2: How soon will I notice a difference? 
Usually within a few days—especially for odor or allergy symptoms. 

Q3: Do I need to clean anything after install? 
No. The system is sealed and self-cleaning for microbial control. 

Q4: Can I DIY the install? 
Not recommended. Improper placement reduces effectiveness and may void warranties. 

Q5: Will it increase my electricity bill? 
Only slightly. Most UV bulbs use about 20 watts—similar to a small lightbulb.
