UV Air Filtration
What UV Actually Does
Your evaporator coil spends every summer wet, dark and cool — close to ideal conditions for mould and bacteria. Growth there does two things: it puts spores into the air you breathe, and it insulates the coil so the system loses efficiency.
A UV-C lamp aimed at the coil keeps that surface sterile. It is not a substitute for filtration — it does nothing about dust or pollen — but for musty smells when the AC starts, and for keeping a coil clean between services, it does a job nothing else does.

What to Watch For
Signs UV Would Help
UV solves a specific problem. These are its symptoms.
-
Musty smell when the AC first starts
The classic sign of biological growth on the coil.
-
High indoor humidity
Damp coils grow more.
-
Allergy symptoms that worsen with the AC running
Suggests the system is distributing something.
-
A coil that fouls quickly between services
UV keeps it clean between visits.
What We Do
UV Services
Correct placement matters more than lamp wattage.
- Coil sterilisation lamps Aimed at the coil surface, where growth actually happens.
- Air-stream UV systems Treating air as it passes rather than the coil alone.
- Annual lamp replacement Output falls well before the lamp stops lighting.
- Retrofit to existing systems Most systems can take one.
How It Works
How We Handle Your UV Air Filtration
A good install is mostly what happens before anyone picks up a wrench.

You get a written proposal with real options at different price points, plus financing if you want it. No pressure and no same-day-only discounts.
-
Permitted, Code-Compliant Installation
We pull the permits the job requires and install to code. Shortcuts here are what turn up years later as a failed inspection or a denied claim.
-
Commissioning and Walkthrough
We verify the system performs to spec, then show you how to run it before we leave. The work is backed in writing.

UV Air Filtration — Common Questions
Can UV Light Air Filters Help With Allergies Or Respiratory Issues?
Do UV Air Filters Help With Allergies And Breathing Issues?
UV light air filters are designed to target biological contaminants like bacteria, mold, and some viruses as air moves through your HVAC system. While they don’t remove dust or pollen directly, they can still play a role in improving indoor air quality, which may help reduce allergy and respiratory symptoms. Here’s how they help:
- Neutralize mold spores that can trigger allergies
- Reduce bacteria and airborne contaminants
- Improve overall air cleanliness when combined with filtration
- Support a healthier indoor environment
For best results, UV systems should be used alongside:
- High-quality air filters to capture dust and allergens
- Duct cleaning and sealing to prevent contaminants from entering the system
- Proper ventilation to improve airflow
In the Texas Hill Country, where dust, pollen, and seasonal allergens are common, combining multiple indoor air quality solutions often delivers the best results. 72 Degrees Texas can evaluate your home and recommend the right combination of filtration, UV systems, and ventilation improvements to help reduce allergy symptoms and improve comfort in Fredericksburg, Kerrville, and surrounding areas.
How Does A Whole-Home Air Purifier Work With My HVAC System And Will It Affect Energy Bills?
How Whole-Home Air Purifiers Work And Their Impact On Energy Use
A whole-home air purifier is installed directly into your HVAC system, typically within the ductwork or near the air handler. As your system runs, air passes through the purifier, where contaminants like dust, allergens, and bacteria are reduced or removed. Because it works with your existing system, it doesn’t require a separate airflow system or major additional energy use. Here’s how it works:
- Air circulates through your HVAC system as usual
- The purifier treats the air before it’s distributed throughout your home
- Cleaned air is delivered to every room connected to your duct system
In terms of energy impact:
- Most systems use very little additional electricity
- Cleaner components, like coils and filters, can improve HVAC efficiency
- Better airflow can reduce how hard your system has to work
In many cases, maintaining a cleaner HVAC system can actually help reduce long-term energy costs by preventing buildup that restricts airflow. In the Texas Hill Country, where HVAC systems run frequently, keeping your system clean and efficient can make a noticeable difference. 72 Degrees Texas installs whole-home air purifiers in Fredericksburg, Kerrville, and surrounding areas, helping homeowners improve air quality without significantly increasing energy use.
Are Air Scrubbers Dangerous?
Are Air Scrubbers Safe For Your Home?
Air scrubbers are generally safe for residential use when installed correctly and maintained as recommended. They are designed to work with your HVAC system to improve indoor air quality, not create hazards. These systems help reduce airborne particles like dust, pollen, and other contaminants that can affect comfort and health. However, there are a few important considerations:
- Proper installation is key to ensure safe and effective operation
- The system should be matched correctly to your HVAC setup
- Regular maintenance helps keep the unit working as intended
Some air scrubbers use advanced technologies to neutralize contaminants, so it’s important to choose a system that is designed for residential use and installed by a qualified professional. In the Texas Hill Country, where dust and allergens are common, air scrubbers can be a helpful addition to improve indoor air quality without introducing risk when properly set up. 72 Degrees Texas can help determine if an air scrubber is right for your home and ensure it’s installed safely for long-term performance.

Can A Whole-Home Air Filter Help With Allergies And Respiratory Issues?
How Whole-Home Air Filters Help With Allergies And Breathing Issues
A whole-home air filter works with your HVAC system to remove airborne particles as air circulates through your home. For homeowners dealing with allergies or respiratory issues, reducing these particles can make a noticeable difference in comfort and air quality. Here’s how whole-home air filters help:
- Capture dust, pollen, and pet dander before they circulate
- Reduce airborne irritants that can trigger allergy symptoms
- Improve overall indoor air cleanliness
- Support a healthier breathing environment
Higher-efficiency filters, such as those with higher MERV ratings, can capture smaller particles and provide better protection for sensitive individuals. For best results, whole-home filtration should be combined with:
- Regular filter replacement to maintain airflow
- Duct sealing to prevent contaminants from entering the system
- Additional air quality solutions if needed, such as UV systems or air scrubbers
In the Texas Hill Country, where dust and seasonal allergens are common, improving filtration can help create a more comfortable indoor environment. 72 Degrees Texas can evaluate your home in Fredericksburg, Kerrville, and surrounding areas to recommend the right filtration setup to help reduce allergy symptoms and improve indoor air quality.
