FAQs
Why is indoor air quality such a concern in Grandview?
Grandview’s mix of hot, humid summers and chilly winters means we spend long periods with windows closed and the HVAC system running. Because modern construction is tightly sealed for energy efficiency, airborne contaminants—pollen, pet dander, dust, and VOCs from household products—can accumulate quickly. Poor indoor air quality (IAQ) can aggravate allergies, trigger asthma, and contribute to headaches or fatigue. A well-maintained heating, cooling, and ventilation system keeps fresh outdoor air circulating and filters pollutants before they reach your living space.
How often should I replace or clean the HVAC air filter?
For most homes in Grandview, a standard 1-inch pleated filter should be changed every 30–60 days when the system is running daily. If you have pets, allergies, a recent renovation, or live close to construction or farmland, check it every 30 days. High-MERV media filters (4–5 inches thick) can last 6–12 months but still need quarterly inspections. A clogged filter reduces airflow, forces the blower to work harder, lowers system efficiency, and allows dust to bypass the filter and circulate indoors.
What common indoor pollutants can my HVAC system help remove?
1. Particulates: Dust, pollen, pet dander, and smoke can be captured by high-efficiency (MERV 11–16) filters. 2. Biological contaminants: Mold spores, bacteria, and some viruses can be reduced with a combination of filtration, UV-C lamps, and proper humidity control. 3. Volatile organic compounds (VOCs): Gases released by paints, cleaners, or new furniture are best addressed with increased ventilation and dedicated activated-carbon filtration or an air purifier. 4. Excess moisture: Whole-home dehumidifiers tied into your HVAC ductwork keep humidity in the 30–50 % range, discouraging mold growth and dust mites.
How does indoor humidity affect comfort and air quality?
When humidity is too high (above 55 %) during Grandview’s summer, your home can feel muggy, and condensation may form on walls or inside ductwork—ideal conditions for mold and dust mites. Too low (below 30 %) in winter, you may experience dry skin, static shocks, and a greater spread of airborne viruses. Your HVAC system can incorporate whole-house humidifiers, dehumidifiers, or variable-speed cooling equipment that automatically balances moisture, improving comfort and protecting wood floors, furniture, and electronics.
What ventilation options exist for today’s tightly sealed homes?
Energy-efficient homes often need mechanical ventilation to bring in fresh air without driving up utility bills. Popular solutions include: • Energy Recovery Ventilators (ERVs) and Heat Recovery Ventilators (HRVs) that exchange stale indoor air with fresh outdoor air while transferring heat and, in ERVs, moisture—maintaining comfort and efficiency. • Dedicated outdoor air intakes tied to the return duct. • Bathroom and kitchen exhaust fans with timers or humidity sensors. A properly sized and balanced system prevents carbon dioxide buildup, removes odors, and dilutes indoor pollutants year-round.
How can I tell if my house needs a professional air-quality assessment, and what happens during one?
Signs you may need an IAQ evaluation include persistent allergy or asthma symptoms indoors, noticeable musty or chemical odors, visible mold, frequent dust buildup, or inconsistent humidity. During an assessment, a certified technician will: 1) inspect HVAC equipment, ductwork, and filter efficacy; 2) measure temperature, relative humidity, and carbon dioxide levels; 3) perform particulate and VOC sampling if necessary; 4) check for mold or moisture intrusion; and 5) provide a written report with recommendations—ranging from filter upgrades and duct sealing to installing air purifiers or ventilation products—tailored to Grandview’s climate and your budget.
