Indoor Air Quality

Frequently Asked Questions

• What causes poor indoor air quality?
  Common causes include dust, pet dander, pollen, mold spores, cleaning product chemicals, off-gassing from furniture and building materials, and inadequate ventilation. In tight, energy-efficient homes, pollutants can accumulate without proper air exchange and filtration.
• How do UV light systems improve air quality?
  UV-C light systems installed in your HVAC system neutralize bacteria, viruses, and mold spores as air passes through. They're particularly effective at preventing mold growth on evaporator coils and in drain pans, common problem areas in humid climates.
• Do I need a dehumidifier in Laredo?
  While Laredo is generally dry, indoor humidity can become an issue during monsoon season or if your AC is oversized. High indoor humidity promotes mold growth and dust mites. A whole-home dehumidifier can help maintain optimal 30-50% humidity levels year-round.
• How do I know if my home has air quality problems?
  Signs include persistent allergies or respiratory issues when home, excessive dust buildup, musty odors, condensation on windows, or family members with worsening asthma. We can test your air quality and recommend targeted solutions.
• What's the best air filter for allergies?
  MERV 11-13 filters capture most allergens including pollen, dust mites, and pet dander. Higher isn't always better—filters above MERV 13 can restrict airflow if your system isn't designed for them. We can recommend the right filter for your system and needs.
• Do UV air purifiers really work?
  Yes, UV-C germicidal lights effectively kill bacteria, viruses, and mold spores that pass through your HVAC system. They're especially beneficial for families with health concerns or homes with recurring mold issues. We install units inside your ductwork for whole-home protection.
