What customers say about indoor air quality services
We were having trouble with water within the walls, and after getting the roof checked, and the water pipes checked, the problem was with the a/c system. Justin came in and after inspection, determined that we needed a humidifier, and all of our vents treated. He also recommended that we get humidity gauges, which we did. They were simple devices and very inexpensive. His work was quickly and very professionally done. And it totally solved the problem. His explanations were very clear, and he answered all of our questions. I would highly recommend him for any work on a/c and heating systems…

What Every Houston Resident Should Ask Before a Service Call
- When does indoor-air-quality work actually help, and when is it upsell?
- Helps for documented issues: high pollen counts (MERV-13 filtration), high-humidity climates (whole-home dehumidifier), wildfire-smoke regions (HEPA + UV-C), and tight modern homes with poor ventilation (ERV/HRV). Skip "duct fogging" and "air sanitizer" upsells — no peer-reviewed evidence they outperform standard filtration.
- What should I look for when verifying an HVAC contractor's credentials in Houston?
- To ensure a provider is legitimate, verify they hold an active Texas Department of Licensing and Regulation (TDLR) HVAC license and carry the required liability insurance. You can confirm their status through the state’s online licensing portal to ensure they meet the professional requirements for operating in Harris County. Reputable companies will readily provide their license number and proof of bonding, which are essential for protecting your property and ensuring code compliance during any repair or installation service.
- How much does HVAC service cost in Houston, TX?
- UV-C germicidal lamp typically runs $225–$625, and ERV/HRV ventilator runs $2,650–$5,800 in Houston, Texas. See the HVAC pricing table on this page for the full per-service breakdown.
