Indoor Air Quality Services in South Pasadena | Due Date: 03/14/2025

Are you concerned about the air your family breathes? Indoor air pollution is among the top environmental health risks facing Californians. There are both external and internal pollution sources, and concentration levels are often much higher inside a home. Certified Service recommends our indoor air quality services in South Pasadena, CA. Our team can test your indoor air quality (IAQ). From there, we can help you explore air purification and other IAQ solutions.

Residential Indoor Air Quality Services

IAQ testing is an excellent first step, and regular testing can keep you aware of changes inside and outside your home. Annual testing is crucial for homes with furnaces and other fuel-burning appliances. It can also reveal issues with dust, moisture, volatile organic compounds, and much more.

Whole-home air purification is usually the most effective way to combat indoor air pollution. We offer in-duct air purifiers that deliver homes of all sizes four or more air changes per hour. These systems often have a high-efficiency particulate air (HEPA) filter for the primary filtration. HEPA filters trap 99.97% of particles as small as 0.3 microns in size. Activated carbon is effective for odor control and the removal of gases and chemicals. You can also opt for an in-duct ultraviolet (UV) lamp. UV lights eradicate up to 99% of viruses, mold spores, and other organic impurities.

If you have humidity issues, we offer humidity control equipment as well. Whole-house dehumidifiers remove moisture from the air to lower relative humidity (RH) in summer. Humidifiers add moisture to the air to raise RH in winter.

Your HVAC equipment is an important consideration as well. Schedule seasonal HVAC tune-ups. Choose a premium HVAC filter and replace it regularly. Our team also recommends scheduling duct camera inspections at least every other year. If you have air leakage, duct sealing will help prevent indoor pollution while improving your home’s energy efficiency. If you have excessive dust accumulation in your ductwork, professional duct cleaning will remove it.
