Air Quality Testing
Different Problems, Different Fixes
Cedar fever is not a figure of speech in the Hill Country. From December through February, mountain cedar pollen counts here run among the highest of any allergen anywhere in the United States, and it gets pulled into the house through every gap and every return.
Add the caliche dust of a dry summer and homes that are sealed tighter than they used to be, and indoor air is frequently worse than what is outside. Filtration, purification and ventilation each address a different part of that — which is why the right answer depends on what is actually bothering you.

What to Watch For
Reasons to Test
If any of these describe your house, testing tells you where to spend.
-
Symptoms that improve when you leave the house
The clearest single indicator that the problem is indoors.
-
Dust that returns days after cleaning
Often duct or filtration related.
-
Musty smell or damp patches
Humidity and possible microbial growth.
-
A new build or a recent remodel
Off-gassing and construction dust both linger.
What We Do
What We Assess
The house and the system together, since one drives the other.
- Filtration and airflow What your system is actually filtering, and at what cost to airflow.
- Humidity levels High and low both cause problems, and both are fixable.
- Ventilation rate Whether the house is getting any fresh air at all.
- Contaminant sources Ducts, combustion appliances, crawl spaces and attic paths.

Air Quality Testing — Common Questions
How Effective Are UV Air Filters In Improving Indoor Air Quality?
How Well UV Air Filters Work In Your Home
UV air filters are designed to improve indoor air quality by targeting biological contaminants that traditional filters don’t address. They use ultraviolet light to neutralize microorganisms like bacteria, mold, and some viruses as air passes through your HVAC system. Here’s what UV air filters do well:
- Reduce mold growth inside HVAC components
- Neutralize bacteria and other microorganisms
- Help prevent buildup on coils and internal system parts
- Support cleaner air throughout your home
However, UV systems do not remove dust, pollen, or pet dander. That’s why they are most effective when used alongside:
- High-quality air filters to capture particles
- Duct sealing to prevent contaminants from entering the system
- Proper ventilation to improve airflow
In the Texas Hill Country, where both allergens and humidity can impact indoor air, combining UV purification with filtration and ventilation provides a more complete air quality solution. 72 Degrees Texas helps homeowners in Fredericksburg, Kerrville, and surrounding areas choose the right combination of systems to improve indoor air quality and overall comfort.
Can Duct Sealing Improve My Home’s Indoor Air Quality?
How Duct Sealing Improves Indoor Air Quality
Leaky ductwork doesn’t just waste energy, it can also pull in dust, insulation particles, and other contaminants from areas like attics, crawl spaces, or wall cavities. When your ducts are sealed, those unwanted pollutants are kept out of your airflow. Here’s how duct sealing helps improve air quality:
- Prevents dust and allergens from entering the duct system
- Reduces the spread of pollutants throughout your home
- Improves filtration by keeping air moving through the proper system path
- Supports better overall airflow and ventilation
In many homes across the Texas Hill Country, ductwork runs through hot, dusty attic spaces. If there are leaks, your system can pull in that air and circulate it throughout your home. Sealing ducts helps ensure the air you’re breathing is coming through your filtration system, not from unconditioned spaces. 72 Degrees Texas can inspect your ductwork and recommend sealing solutions to help homeowners in Fredericksburg, Kerrville, and surrounding areas improve both comfort and indoor air quality.
Can My Heating Or Cooling System Affect Indoor Air Quality?
How Your HVAC System Impacts Indoor Air Quality
Your HVAC system doesn’t just control temperature, it also plays a major role in the quality of the air you breathe. As air circulates through your system, it passes through filters, ducts, and components that can either remove contaminants or spread them if not properly maintained. Here’s how your system can affect indoor air quality:
- Dirty air filters can allow dust, pollen, and allergens to circulate
- Leaky ductwork can pull in contaminants from attics or crawl spaces
- Poor airflow can lead to stale, stagnant air
- Moisture buildup in the system can promote mold growth
- Unclean components can spread debris throughout your home
On the other hand, a well-maintained HVAC system helps:
- Filter out airborne particles
- Maintain proper airflow and ventilation
- Support balanced humidity levels
- Improve overall indoor air quality
In the Texas Hill Country, where dust and seasonal allergens are common, keeping your HVAC system clean and properly maintained is key to maintaining healthy air. 72 Degrees Texas can inspect your system and recommend services like filter upgrades, duct cleaning, sealing, or air purification to help improve indoor air quality for homeowners in Fredericksburg, Kerrville, and surrounding areas.
How Can I Tell If My Home Has Poor Indoor Air Quality?
Signs Your Home May Have Poor Indoor Air Quality
Indoor air quality issues often show up through changes in how your home feels and how you feel living in it. If air isn’t properly filtered or ventilated, contaminants can build up and circulate throughout your home. Common signs of poor indoor air quality include:
- Frequent allergies, headaches, or respiratory irritation indoors
- Excess dust buildup even after regular cleaning
- Musty, stale, or lingering odors
- Uneven airflow or stuffy rooms
- Visible mold or mildew in certain areas
You may also notice your HVAC system running more often or struggling to maintain comfort, which can be tied to airflow or air quality issues. In the Texas Hill Country, where dust, pollen, and seasonal changes are common, indoor air quality problems can develop quickly if systems aren’t properly maintained. 72 Degrees Texas can evaluate your home in Fredericksburg, Kerrville, and surrounding areas to identify air quality issues and recommend solutions like filtration upgrades, duct services, or ventilation improvements to help restore clean, healthy air.
How Often Should I Have My Home’s Indoor Air Quality Tested?
How Often To Test Indoor Air Quality In Your Home
Indoor air quality testing isn’t something most homeowners think about regularly, but it can play an important role in maintaining a healthy living environment. In general, testing every 1 to 2 years is a good baseline. However, you may want to test more often if you notice signs of air quality issues. You may need testing sooner if:
- You experience frequent allergies or respiratory symptoms indoors
- You notice persistent odors or stale air
- Your home feels overly dusty or humid
- You’ve recently completed renovations or remodeling
- Your HVAC system isn’t performing as expected
In the Texas Hill Country, where dust, allergens, and seasonal changes can impact indoor air, periodic testing can help identify problems early before they affect comfort or health. 72 Degrees Texas can evaluate your home and recommend the right indoor air quality solutions based on your results, helping homeowners in Fredericksburg, Kerrville, and surrounding areas maintain cleaner, healthier air year-round.
