Sweetwater Home Services has served more than 35,000 Central Texas households since 1987, helping homeowners understand what is affecting the comfort and quality of their indoor spaces. A free indoor air quality test gives you a clearer look at what may be circulating through your home, including allergens, smoke particles, humidity-related concerns, and other airborne contaminants. Instead of guessing, you get real information from an in-house Sweetwater technician at no cost and with no obligation to purchase anything.
What Happens During Your Free Air Quality Test
Your free air quality test is completed in your home by a Sweetwater technician, not through a mail-in kit or a do-it-yourself checklist. During the visit, we evaluate the air quality in your space, explain our findings, and help you understand how they compare to acceptable indoor air quality levels.
The evaluation focuses on the factors that matter most in Central Texas homes, including airborne allergens, fine smoke particles, and humidity levels that may contribute to mold or mildew concerns. When the visit is complete, you’ll have straightforward information about your home’s indoor air and the options available if something needs attention. The test is completely free, and there is no obligation to move forward with any product or service.
What Air Quality Issues We Look for in Central Texas Homes
Indoor air quality concerns can look different from one home to the next, but Central Texas has a few common issues that often show up. During your free air quality test, Sweetwater looks at the conditions most likely to affect homes in the Austin and San Antonio areas.
Pollen: Oak, cedar, and ragweed seasons can significantly affect indoor comfort, especially for households already sensitive to seasonal allergens.
Dust and Pet Dander: These common indoor particles can accumulate year-round and continue to circulate throughout the home.
Wildfire Smoke Particles: When smoke moves into Central Texas, fine particles can enter homes and remain suspended longer than many homeowners expect.
Humidity-Related Concerns: Moisture fluctuations can create conditions that make mold and mildew more likely to develop, especially in less visible areas.
VOCs: Paints, cleaning products, adhesives, furniture, and other household materials can release volatile organic compounds that affect indoor air quality.
The goal of the test is not to create worry. It is to help you understand what is present in your home so you can make a clear decision about what to do next.
Stand-Alone HEPA Air Purifiers: Our Air Quality Solution
If your air quality test shows a concern worth addressing, Sweetwater offers stand-alone HEPA air purification units as a next step. These units remove 99.97% of airborne particles at 0.3 microns, which includes many allergens, smoke particles, and fine particulate matter. A single unit covers up to 2,500 square feet, making it a practical option for large rooms, open living areas, and connected spaces.
These air purifiers do not connect to your HVAC system and do not require ductwork. They are fully stand-alone units, so there is no need to modify your heating and cooling system or make structural changes to your home. Placement is straightforward, and our team can walk you through how the unit works.

Professional service. On time. Great communication from office staff and Technician alike. They told me the amount due at the time of making the appointment, and then mount stayed the same all the way through the service. He even changed out some parts that were wearing thin At no extra charge.
I would have to say this was one of the best presentations I've had in awhile. I learned a lot about the water inside my home and about how that water is affecting my fixtures and family. I am so glad that we decided to go with RainSoft for our family. And a great big thank you to Frank for educating us and taking the time to answer all our questions!
The water quality test was conducted in a professional manner and Gina explained everything in simple terms. Thank you Gina!
