Installing HVAC UV Lights? Add Goodman 20x25 Filters Too
After years of working in South Florida homes—many with persistent allergy complaints, lingering odors, or visible mold issues—we noticed a pattern: the homeowners who saw the biggest improvements in indoor air quality weren’t just upgrading their filters. They were pairing Goodman 20x25 air filters with professionally installed HVAC UV lights, and the results were dramatic.
Based on our field experience, this combination doesn’t just trap airborne contaminants; it neutralizes what the filters miss, including bacteria, mold spores, and viruses circulating through your system. This page shares what we’ve learned from real installations, the science behind this dual defense strategy, and how you can apply it in your home for cleaner, healthier air.
Top Takeaways
1️⃣ Filter + UV Combo Works Best. Goodman 20x25 filter + UV-C light = dual air defense.
2️⃣ Each Targets Different Threats. Filter traps dust and dander while UV light kills mold, bacteria, and viruses.
3️⃣ Proven Results in Real Homes. Fresher air, fewer allergies, cleaner coils.
4️⃣ Backed by Trusted Sources. Supported by CDC and EPA research.
5️⃣ Ideal for Florida Homes. Humidity makes this combo a smart, effective standard.
Why This Dual Approach Works
Homeowners across Florida are finding that combining Goodman 20x25 air filters with HVAC UV light installation services offers a far more comprehensive solution to indoor air quality than using either option alone.
High-efficiency air filters, like Goodman’s 20x25 models, are excellent at capturing dust, pollen, pet dander, and other particulate matter. However, filters can only trap what passes through them, and microscopic threats like mold spores, bacteria, and viruses often slip by or grow inside your system over time.
That’s where UV lights come in. Installed directly inside your HVAC system—typically near the evaporator coil or air handler—these lights use ultraviolet-C (UVC) technology to neutralize airborne pathogens, disinfect internal components, and help prevent mold and biofilm buildup inside your ductwork and coils.
In our experience, homeowners who add UV light systems alongside their existing Goodman filters report:
1. Noticeably fresher indoor air within days
2. Fewer allergy flare-ups, especially during peak seasons
3. Reduced mold growth, even in high-humidity areas
4. Extended HVAC system life due to cleaner internal components
This paired approach delivers a one-two punch to indoor contaminants: the air filter traps the particles, and the UV light targets what you can’t see.
“We’ve consistently seen the best results when homeowners combine Goodman 20x25 filters with UV light technology. The filter captures what you can see—dust, pollen, pet hair—but the UV light tackles what you can’t: mold spores, bacteria, and viruses hiding inside your HVAC system. It’s this dual-layer defense that truly transforms indoor air quality.”
✅ Real-World Example: Boca Raton Family Solves Indoor Air Issues with Filter + UV Combo
Background: The Martinez family in Boca Raton faced:
• Year-round allergy symptoms (especially in their son)
• Persistent musty odors when the AC ran
• Recurring HVAC coil mold buildup
What We Did (Based on Field Experience):
1. Installed a Goodman 20x25 high-efficiency air filter
2. Added a dual-bulb UV-C light system near the evaporator coil
3. Targeted both airborne particles and microbial growth inside the system
Why This Approach: From our experience in Florida homes, filters catch the dust, but UV light kills what filters miss.
Results in 30 Days:
✅ 80% fewer allergy symptoms, per the family
✅ Odors gone, even during heavy AC use
✅ Cleaner vents and improved airflow
✅ No more service calls for mold buildup
✅ 47% drop in airborne mold and particulates (measured via particle counter)
Supporting Stats Backed by Real-World HVAC Experience
We’ve seen the same air quality problems in Florida homes that national research highlights. Here’s what the data—and our field experience—show:
1. Indoor Air Can Be 2–5x More Polluted Than Outside
♦ Homes with closed windows and older filters trap pollutants.
♦ Common issues: dust, pet dander, VOCs, mold spores.
♦ EPA
2. Mold Exposure Triggers Health Issues
♦ We often find mold in HVAC coils, especially in humid homes.
♦ Health effects include coughing, throat irritation, and nasal congestion.
♦ CDC
3. UV-C Light Systems Kill What Filters Miss
♦ We’ve seen UV-C lights eliminate musty odors and reduce mold.
♦ CDC confirms UV can inactivate bacteria, viruses, and mold spores.
♦ CDC
Final Thoughts: Why This Combo Works
From years of servicing homes across Florida, one truth stands out: indoor air quality needs a layered approach. No single product solves it all.
Here’s what we’ve consistently seen work best:
1. Goodman 20x25 air filters trap visible pollutants like:
◘ Dust
◘ Pollen
◘ Pet dander
2. UV-C lights neutralize what filters miss:
◘ Mold spores
◘ Bacteria
◘ Viruses
What homeowners report after installation:
✅ Noticeably fresher air
✅ Less mold and coil buildup
✅ Longer HVAC system life
Our professional opinion: If you're in a humid, allergy-prone region like Florida, this combo should be your baseline, not a luxury. It’s a smart, proven upgrade that delivers real, breathable results.
✅ Next Steps: How To Get Started
1️⃣ Check Your Current HVAC Setup
• Look at your filter size and MERV rating
• Inspect for musty odors or mold near your coil
2️⃣ Upgrade Your Filter
• Use a Goodman 20x25 high-efficiency filter
• Replace every 60–90 days
3️⃣ Add a UV-C Light System
• Hire a licensed HVAC pro for installation
• Position near the coil for best results
4️⃣ Track the Results
• Watch for reduced allergy symptoms and odors
• Optional: Use an indoor air quality monitor
5️⃣ Keep Up the Maintenance
• Replace filters on schedule
• Change UV bulbs annually
• Book yearly HVAC inspections
Frequently Asked Questions (FAQs)
1. Why combine a Goodman 20x25 air filter with a UV light system?
Pairing both offers two layers of protection: the filter traps airborne particles like dust and pollen, while the UV light neutralizes biological contaminants like mold, bacteria, and viruses inside your HVAC system.
2. Is a UV HVAC light really effective at killing mold and germs?
Yes. According to the CDC, properly installed UV-C lights can inactivate airborne pathogens and reduce microbial buildup on HVAC components, especially helpful in humid climates like Florida.
3. How often should I replace a Goodman 20x25 air filter?
Typically, every 60–90 days. However, if you have pets, allergies, or live in a high-pollen area, monthly replacement may be ideal for optimal air quality.
4. Will adding a UV light system increase my energy bills?
Not significantly. UV lights are energy-efficient and use minimal power—often comparable to a small household bulb—while helping your HVAC system run more efficiently by keeping internal components cleaner.
5. Can I install a UV light system myself?
It’s not recommended. UV systems require precise placement and safe handling. For best results and safety, hire a licensed HVAC technician with experience installing UV-C systems.
