FAQs
Why is indoor air-quality testing important for homes and businesses in Loudon?
Loudon’s mixed climate means buildings are closed up for heating in winter and air-conditioning in summer, allowing pollutants to accumulate. Dust, pollen, mold spores, volatile organic compounds (VOCs) and combustion by-products can trigger allergies, aggravate asthma, and reduce overall comfort. A professional air-quality test pinpoints exactly what is in your air so we can recommend targeted solutions instead of guesswork.
What does a professional air-quality test include?
Our technicians start with a visual HVAC and building envelope inspection, then deploy calibrated instruments to log temperature, humidity, carbon monoxide (CO), carbon dioxide (CO₂), and particulate levels (PM2.5/PM10). We collect air samples for lab analysis of mold spores, bacteria, and VOCs. Results are delivered in an easy-to-read report within 3–5 business days, along with actionable recommendations such as filtration upgrades, duct cleaning, or humidity control.
How often should my heating and air-conditioning system be checked to maintain good air quality?
We recommend a full HVAC tune-up and filter replacement every six months—once before the cooling season and once before the heating season. Households with pets, smokers, or allergy sufferers should consider quarterly filter changes and an annual duct inspection. Regular maintenance not only preserves air quality but also improves energy efficiency and equipment life.
What ventilation and filtration options are available if my test shows poor air quality?
Solutions range from high-MERV pleated filters and HEPA bypass filters to UV-C germicidal lamps, activated-carbon media for odor/VOC removal, and energy-recovery ventilators (ERVs) that introduce fresh outdoor air without large energy losses. For persistent humidity issues, whole-home dehumidifiers can be tied into existing ductwork. Our team will size and install the right combination for your Loudon property.
Will upgrading my thermostat or scheduling smart maintenance really improve air quality?
Yes. Smart thermostats can run your fan at low speed between heating or cooling calls, constantly pulling indoor air through the filter. Many models also monitor relative humidity and remind you when it’s time to change filters or schedule service. When paired with our preventive-maintenance program, you’ll ensure your filtration, coils, and drain pans stay clean—key factors in healthy indoor air.
How long does an air-quality test take and what does it cost in the Loudon area?
On-site testing typically takes 60–90 minutes for a standard 2,000-sq-ft home, longer for larger or multi-zone commercial spaces. Prices start at approximately $249, which includes sampling, lab fees, and the follow-up consultation. Because every building and concern is unique, we provide a firm quote upfront and credit the testing fee toward any remediation or HVAC upgrades you choose to complete with us.
